Since the publication of the first and second editions of this book, some things have not changed. Today, engineers still have a moral, legal, and ethical responsibility to protect the public in professional practice and in design of products, buildings, processes, equipment, work, and workplaces. The importance of safety in engineering education remains a concern for most engineering degree programs. There is still a need for safety and health specialists who help employers, manufacturers and others to protect people, property and the environment. They must recognize, evaluate, and control hazards. They must assist management, supervisors, and workers to use safe practices so all employees return home safely each day. Yes, there is still a need for this book.
Also since the second edition, many things have changed. There are regulatory changes, changes in technology, changes in business practices, and broadening of participants in achieving safety. Perhaps the greatest changes have resulted from the Internet and its influence on information, communications, and work. While the third edition of this book reflects many such changes, it is impossible to capture all changes affecting safety. In addition, change is constant and a book cannot keep up with change. That is why this edition tries to link readers to new information resources.
Technology continues to change. Computer technology has changed the toolbox for nearly every professional field and it impacts safety practice as well. At first, personal, desktop computers took over the role of most mainframe systems. Now applications work on cell phones and tablets and allow individuals to carry tools with them in their pockets or briefcases. Technology has compressed information storage. Volumes of paper records, photographs, hard copy books, and other documents now fit into memory devices the size of a button.
Not only has the Internet offered an explosion in information and access to it, it has linked people through new devices in new ways. For nearly a century, the telephone linked places. You called a business or home. Today, cell phones and other devices link individuals wherever they are. The links offer voice, text, photos, applications, and data in ways never possible. Concurrently, a challenge for everyone is differentiating quality information from misinformation in nearly every field, including safety and health. Individuals must decide what is valid and reliable information.
Technology has changed businesses and the global economy as well. Companies no longer need layers of employees who formerly collected, processed, evaluated, and reported on business information vital to success. Anyone authorized at any organizational level can access data and reports electronically.
Today, companies organize work differently from the past. The hierarchical structure of work and its supervision has shifted to increased use of teams. The role of supervisors has shifted to team leaders with leading, coaching, and mentoring responsibilities. Work teams have increased participation in recognizing and controlling hazards related to their work, rather than reporting problems to a safety department for action.
The overall field of safety has changed. Safety and health professional work demands higher levels of education. Roles of safety and health professionals have shifted from implementing safety details to overseeing strategies, methods, and practices that achieve safety. The changing roles reflect the business practice of moving safety knowledge and skills deeper into organizations and workgroups.
There continues to be a convergence of related areas. In the 1960s and 1970s, the United States passed a range of laws to protect workers and the environment. At that time the approach was one of specialization in safety, industrial hygiene, environment science and engineering, fire protection, occupational health and nursing, and related fields. More recently, many companies have combined these functions into a single organizational unit. That increased the need for generalists while retaining a need for specialists. Since the tragedy at the World Trade Center on 9/11/2001, some in safety and health have security as an additional responsibility.
Another kind of change involves laws, regulations, and standards. The regulatory system in the United States continues to assign responsibility to government units. There continues to be a shift from state and local government toward the federal level to decide how best to protect people, property, and the environment. The system relies heavily on government prescribing details in regulations and standards.
In the United Kingdom and other Commonwealth countries, there was a shift away from central government toward risk management assigned to employers, manufacturers, and workers. In the United States, some have begun to adopt this approach.
In addition, there is a growing emphasis on management systems and a global expansion of standards for them. The shift started with general business management systems, such as those covered by ISO 9000. Now they also encompass environmental, safety, and health management systems.
An original goal for this book was helping engineers and others gain a broad, quick overview of safety and health practices. Another goal was identifying some of the detailed resources that may provide expanded help in specific topics. An additional goal was making the content easy to read and comprehend.
It has been rewarding to learn how the book continues to meet these goals. One exciting kind of feedback has been meeting people who have used this book. A number reported that the book helped them improve their understanding of safety and health. Others reported that the book remains a key reference at their desks. An exciting report was from a group of Indonesian engineers completing a special program in safety engineering at a university in the United States. They voted this book the easiest to read during that program.
Completing this third edition remains a work devoted to the love of the engineering and safety professions, even after retirement from full-time employment. While completing my education, my goal was to find ways to apply engineering for the benefit of people. With this third edition, my hope is to continue helping engineers who have an ethical and professional responsibility to protect the health, safety, and welfare of the public. I also hope the book helps those seeking roles in safety and health or expanding such roles.
I must continue to thank those who guided me into the safety, health, and ergonomics fields from my engineering background. Many helped motivate me to complete the first, second, and now the third editions. My greatest thanks goes to my wife, Char, who has supported my professional work over the years. I also thank my children, Michelle and David, and my grandchildren, Matt, Michaela, Nicolas, and Reagan, who also gave me support and motivation while tolerating time often stolen from or interrupting family activities.

Modern Western society continues to place a high value on human life. That was not always the case. Even today, some societies place a limited value on human life.
In the United States today, life expectancy for males is 76 years and 81 years for females and increasing slowly. Some other developed countries have slightly higher life expectancies. Some underdeveloped countries have life expectancies around 50 years.
In the past few centuries, engineering and medicine have all but eliminated some diseases that previously were major threats. Examples are smallpox, typhoid, cholera, bubonic plague, diphtheria, tuberculosis, and polio. Medicine has contributed vaccinations, improved treatments, and the use of antibiotics. Engineering contributed sanitation systems to manage human and other waste and to prevent the spread of diseases and illnesses by treating water.
Today we are on the threshold of biological medicine that helps with diagnosis and treatment of disease. A few drops of blood can test for nearly 1,000 medical conditions. Mapping of the DNA molecule and DNA testing can now link many diseases to individual conditions. Biologically grown substances, tissue, and even organs are leading to revolutionary treatments.
The industrial revolution occurred between 1760 and 1840. Early in the industrial revolution, the life expectancy for the working class in Manchester, England, was 17 years. For the gentry living in the country on manors, life expectancy was 35 years. Child labor was common. The industrial revolution introduced new hazards to workers. Early on, the rate of injury and death at work was very high, often from machines. While the rates have come down a lot, there is still much to be done. New equipment and technology have added hazards, often extending from workers to the general population. For example, the automobile continues to cause significant injury and death to the general population. The number of chemicals and materials in daily use has exploded. The CAS Registry1 contains more than 65 million entries with 15,000 additions daily. There are about 300,000 inventoried or regulated substances. We know little about the safety and health hazards of many of these substances.
The industrial revolution spawned a major safety movement. The result was government laws and regulations aimed at protecting workers. Early in 1900, many new organizations devoted to safety and health were founded. One surviving example is the National Safety Council. There were many others at national, state, regional, and industry levels. Many no longer exist. Another derivative of the industrial revolution is workers' compensation, the idea that workers receive compensation for work-related injuries.
What is the value of a human life today? In defending proposed regulations, federal agencies often estimate the value of human life. The Environmental Protection Agency has used $9.1 million. The Food and Drug Administration estimated human life at $7.9 million. The Transportation Department set human worth at $6 million. The average payout for victims of the 9/11 terrorist tragedy in New York in 2001 was $2.1 million. Some insurance companies use $50,000 per year in managing insurance decisions.
Governments, employers, and individuals spend significant money to avoid loss of human life and to prevent injuries and illnesses. Many buy insurance to cover the financial risks related to death, injury, illness, and property loss. For employers, there is also the resulting return on such investments.
Many professions, including engineers and others, play significant roles in these protective endeavors. Protection focuses on people, property and the environment. While all are important, this book will focus primarily on people. The book will concentrate on matters that cause injury, illness, and death. Injury, illness, and death can occur at work, at home, while traveling and during leisure and recreational activities. This book mainly addresses work situations. However, discussion of some topics extends to other activities as well.
Why is safety important? Why bother with it? There are three general reasons.
One reason is humanitarianism. Many societies place value on human life and welfare. Not all societies have the same degree of regard for people. Having value for human life is a moral basis for the field of safety and health.
Another reason is the law. Different societies use different standards for right and wrong. Societies set standards of conduct through laws and regulations. This reason for safety derives from the first. Laws define a society's moral code. The laws protect the safety, health, and welfare of individuals, property, and the environment.
Cost is a third reason. Some governments and businesses have established a value for human life. Some have established values for injuries and illnesses. The costs involved in injury, illness and death are part of the economic system of a society. So are costs for loss of property. Damage to the environment may also incur costs as part of business. Society often defines the costs through laws.
Humanitarianism has many aspects derived from the value placed on human life, property and the environment in which we live. Humanitarianism represents the moral part of safety and health. Protecting people is the right thing to do, the moral action.
Humanitarianism varies with societies. Some place a high value on human life, property, and the environment. Others have little regard for these elements, especially when one group has different views from other groups. The differences may involve political or religious factors or other characteristics.
The moral aspect of safety and health often is linked to professional ethics. Many codes of professional conduct and ethics place high value on human life. For example, the National Society of Professional Engineers (NSPE) places protection of people at the top of its Code of Professional Conduct:2
I. Fundamental Canons
Engineers, in the fulfillment of their professional duties, shall:
Hold paramount the safety, health, and welfare of the public.
The Code continues later with the first Rule of Practice:
II. Rules of Practice
Engineers shall hold paramount the safety, health, and welfare of the public.
If engineers' judgment is overruled under circumstances that endanger life or property, they shall notify their employer or client and such other authority as may be appropriate.
There are other codes of ethics and professional conduct for those involved in safety and health. The codes have similar provisions placing high importance on protecting people, property, and the environment.
Many companies have set a moral standard for their businesses that defines responsibilities to their stakeholders. These companies make a commitment to those they serve, including employees, customers, communities and others. Corporate Social Responsibility refers to operating a business in a manner that accounts for the social and environmental impact created by the business. Often CSR policies include commitments to the safety and health of workers, customers and communities, and action plans to implement them. The Internet shows many sources of help with CSR and examples of corporate CSR statements and action programs.
In 1984, chemical releases in Bhopal, India, killed between 2,300 and 16,000 people (depending on estimates) and harmed as many as 550,000 others. As a result, the American Chemical Society set up a program called “Responsible Care.” This program reflects the moral basis for the field of safety and health. The program sets standards that guide producers and users of chemicals in protecting people, property, and the environment.
Another moral concept involving protection of people, property, and the environment is sustainability. Sustainability is similar to CSR. One definition of sustainability is “improving the quality of human life while living within the carrying capacity of supporting eco-systems.” Sustainability involves three elements: economy, society, and environment.
One study asked senior executives from around the world to rank their top ten challenges. Overall, sustainability came in ninth. The European Union (EU) has proposed setting sustainability reporting requirements as part of the Global Reporting Initiative (GRI). The goal is to improve transparency and accountability to the public.
Some studies have included safety and health as part of the sustainability concept. Safety and health are simply parts of the societal element of sustainability. The Center for Safety and Health Sustainability3 addresses ways to assure that employee safety and health become part of sustainability globally.
The domain of laws, regulations and standards that require protection of people, property and the environment has many parts. Individuals, companies, and organizations seek to comply with them. Part II of this book deals with laws, regulations, and standards in greater detail.
In general, society codifies protection through laws enacted at international, national, state or province, and local government levels. Often, government agencies issue regulations and standards as interpretations of laws. Laws may conflict with each other, a problem for those trying to comply.
In addition, groups of interested parties, such as companies, industry groups and associations or others, may create and publish voluntary or consensus standards applicable to their groups. A variety of associations and organizations engage in the creation of these standards.
Finally, standards may refer to standards of practice. These are generally accepted practices by crafts, professions, managers or others without formally codifying them.
There are many kinds of costs associated with the protection of people, property, and the environment. One way to discuss costs involves dividing costs into direct and indirect costs.
For safety and health, there are direct costs focused on prevention of injury, illness, and death. Examples are training on how to perform jobs properly and safely. There are costs for equipment and clothing to prevent injuries, illness, and deaths. There are costs to complete work effectively.
There are safety costs for employers. Examples are creating a brand that includes safety concepts and creating loyalty of employees and customers in support of safety. Costs may include creating a positive image for a company or a product that includes safety. There are costs to incorporate safety into designs and the testing of products and processes.
There are costs to comply with laws, regulations, and standards. There are costs to establish and operate safety management systems, covered in Part V. Preventive costs should have significant returns on investments and contribute to business financial success.
When there is a loss, there are many possible costs. Treating injuries and illnesses incur costs. Deaths create costs. The costs may involve cleanup, recovery, repair, and replacement of materials, equipment and facilities and hiring and training new personnel. Investigations have expenses. Lost production and productivity cost money. Insurance and processing of insurance claims incur costs. There may also be costs related to preventing or resolving legal challenges related to loss events.
Many statistics tell stories about the protection of people, property, and the environment. Over the years, many people have helped improve the performance statistics. However, much remains to be done. In addition, change brings new challenges to address.
The terminology has changed over the years. Some time ago records tracked injuries, illnesses and deaths from “accidents.” Today, records use the term “unintentional” instead, such as unintentional injury deaths.
In April, 2014, a garment factory in the Rana Plaza of Dhaka, Bangladesh, collapsed, killing 1,129 people and injuring 2,515 others. An investigation report blamed the mayor for wrongly granting construction approvals and the owner for bribing local officials for construction permits. It appears that the project used substandard materials and had a blatant disregard for building codes.
The day before, cracks had appeared in the building, shaking the structure. An engineer who then inspected the building declared it unsafe, but factory bosses disregarded the concerns and ordered workers into the building the next morning.
The disaster sparked global responses. New safety standards for garment factories in third world countries and closer involvement in supply chains by major retail companies from the United States and other countries were instigated. Many saw the need for clothing retailers to conduct audits of supplier facilities and safety practices as part of their corporate social responsibilities.
Wal-Mart Stores does business with more than 200 factories in Bangladesh and began inspecting all of them after the April 2013 tragedy. The first 75 audits cost more than $4 million. Wal-Mart found that nearly half of the factories failed the initial safety inspections. One factory was torn down and others faced major changes. Wal-Mart stopped doing business with two of the 75 factories. It employed 10 engineers to regularly inspect factories in Bangladesh and posted the audit results on its website.
The International Labour Organizations (ILO) estimates 4 that around the world:
Every 15 seconds, a worker dies from a work-related accident or disease.
Every 15 seconds, 160 workers have a work-related accident.
Every day, 6,300 people die as a result of occupational accidents or work-related diseases.
Every year, 317 million accidents occur on the job.
Every year, there are more than 2.3 million deaths per year.
The annual economic burden is 4% of global Gross Domestic Product.
The World Health Organization statistics for 2008 show that there were nearly 4 million unintentional injury deaths worldwide. The average unintentional fatality rate among all age groups was 59 per 100,000 population. Road traffic accidents were the leading unintentional fatality cause for all age groups under 70.
The globalization of businesses and the interconnection among world economies cause change. Companies and entire industry groups have a growing responsibility to ensure safe practices among their global partners. There are many examples, see the Bangladesh story in Case1-1 that highlights such efforts among retailers.
Another example is the global pressure on the airline industry to improve the overall safety of air travel. 5 During 2012 and 2013, there was a significant drop in airline fatalities below the 10-year average of 750 fatalities. In 2013, there were 29 airline accidents and a record-low 265 fatalities for about 31 million passenger and cargo commercial flights worldwide. In 2012, there were 23 airline accidents and 475 fatalities. Qantas Airline is one of the safest airlines in the world and has not had a fatal accident since 1951.
The European Aviation Safety Agency (EASA) reported that there were 17 commercial (non-cargo) air transport aircraft accidents in 2013, compared with an average of 27 annually during the last decade. 6 During the same periods, there were 224 fatalities compared to an average of 703. There were no fatal crashes among EASA member companies during 6 million flights in 2013, carrying 800 million passengers.
There are at least three major sources of injury, disease, and death statistics in the United States. One is the Centers for Disease Control and Prevention (CDC). Another is the Bureau of Labor Statistics (BLS). These are federal government agencies. A private source is the National Safety Council. In addition, there are many other federal and state agency sources for injury data. Overall, the data show that accidental injuries are significant. After achieving major reductions, there is still an ongoing need to prevent injuries, illnesses, and deaths.
CDC has several data collection and analysis resources. An agency within CDC is the National Center for Injury Prevention and Control (NCIPC). 7 Its mission is to prevent violence and injury and reduce their impacts. The agency operates an online database of injury data and statistics called “Web-based Injury Statistics Query and Reporting System” (WISQARS). This is an interactive database system that provides customized reports of injury-related data.
NCIPC data for 2010 include the following:
120,859 unintentional injury deaths.
26,009 unintentional fall deaths.
33,687 vehicle traffic deaths.
33,041 unintentional poisoning deaths.
More than 180,000 total injury deaths each year.
Injuries are the leading cause of death for people ages 1 through 44.
About 2.5 million people hospitalized with injuries each year.
About 31.6 million people treated for injuries in emergency departments each year.
Violence and injuries cost more than $406 billion annually.
The overall death rate from all causes in 2011 was 807 per 100,000 population. Table 1-1 lists the top ten causes of death in 2011 for the total population, based on death rates.

BLS, an agency within the U.S. Department of Labor, compiles work-related injury, illness and death statistics for workers in the United States. 8 BLS refers to this activity as the Injuries, Illnesses and Fatalities (IIF) program. While the Occupational Safety and Health Administration (OSHA) sets rules for work-related injury and illness recordkeeping, BLS compiles information from data submitted by employers. Refer to BLS annual and other reports for detailed statistics on injuries, illnesses, and deaths broken down by age, industry, occupation, injury type, and other factors.
Results for 2012 include 4,693 fatal work injuries, the third lowest since the Census of Fatal Occupational Injuries (CFOI) began in 1992. The overall fatal injury rate in 2012 was 3.5 per 100,000 full-time equivalent workers.
Here are a few facts from the 2012 report about work-related deaths:
1,789 were transportation related, with 1,044 occurring on roadways.
125 involved aircraft incidents.
463 were homicides and 225 suicides.
668 died from slips, trips, and falls, with 544 from falls.
509 resulted from objects or equipment striking people.
838 occurred in construction-related occupations.
1,150 occurred in transportation and material moving occupations.
224 occurred in protective service occupations.
245 occurred in farming, fishing, and forestry occupations.
429 occurred in management occupations, with 268 in agricultural business.
For several decades, the National Safety Council (NSC) has compiled data on accidents, incidents, injuries, illnesses, and deaths. An annual publication provided detailed analysis of the data. For many years the publication title was Accident Facts. More recently, the title is Injury Facts. This publication breaks down data and analysis into three groups: occupational, motor vehicle, and home and community. Also the publication now reports information on intentional injuries, such as assaults and self-harm. Data come from a variety of sources.
The U.S. population today is four times larger than in 1903. During the same period, the annual number of unintentional deaths has increased from about 70,000 to more than 120,000. The death rate per 100,000 has decreased from about 90 to about 40. This shows some progress, but much preventive work remains.
Table 1-2 shows the NSC-reported unintentional injury deaths information for 2009. The data provide a picture of current performance.

For 2012, NSC reported information about work-related injuries and illnesses. For example, the top three events leading to injuries, the rate per 100,000 workers and median days away from work include:
Overexertion and bodily reaction (39.8, 12)
Slips, trips or falls (27.8, 11)
Contact with object or equipment (25.5, 5).
Also for 2012, NSC reported the five deadliest industry sectors and death rates per 100,000:
Agriculture (21.2)
Mining, quarrying, and oil and gas extraction (15.6)
Transportation and warehousing (13.3)
Construction (9.5)
Wholesale trade (5).
Similarly, the five deadliest occupations in 2012 were (along with death rates per 100,000):
Logging workers (127.8)
Fishers and related fishing workers (117)
Aircraft pilots and flight engineers (53.4)
Roofers (40.5)
Structural iron and steel workers (37).
The above are samples of injury and death statistics. The aim is to illustrate how well or badly modern society is preventing injuries and deaths. While work-related injury and death rates continue to go down, the need remains to ensure that workers and others return home safely each day.
Change is constant. The rate of change appears to be increasing, almost accelerating. There are changes in materials, technology, business practices, societal expectations, and governments and elsewhere. Each of these affects people and the risks they face at work and home as well as in travel and recreation. Not everyone will recognize or understand the changes. Not everyone will learn how to deal with the changes. Not everyone will recognize the risks and foresee how to reduce potential harm.
This section will provide a few examples of challenges for safety and health practice.
Up to 7,500 gallons of a chemical, 4-methylcyclohexane methanol, leaked from a 40,000 gallon Freedom Industries Inc. storage tank and surrounding dike into the Elk River in Charleston, West Virginia, in the USA. The tank was about a mile and a half upstream from an inlet for the public drinking water of the city and surrounding communities. The water system supplied about 300,000 people. The chemical is used in coal processing. The brick and concrete dike was failing and needed repair. Officials learned of the spill from odor reports, located the source within hours, and took action.
For days the water supply was not useable for drinking, cooking or washing. Officials quickly told all residents affected, but some experienced skin and other problems before understanding the dangers. Local and state agencies quickly trucked in water and set up distribution points.
After five days, the contaminated river water had moved downstream and become diluted. Sampling showed the contaminant levels were below toxic levels or there was no contaminant. The water company then began a process of flushing supply pipes and allowing customers to flush their water pipes to remove any contaminated water. The flushing protocol took several days to avoid excess demand on the supply system. Weeks later, many individuals claimed that risks and resulting health conditions remained. Many people did not trust the public water supply for some time.
Initial studies determined that the facility had not received any inspections from federal or state environmental agencies for years. The chemical was not very hazardous. There were few inspectors and they focused on more hazardous sites. Freedom Industries Inc. had purchased the facility about a month before the spill. Within days of the spill, Freedom Industries filed for bankruptcy.
A few weeks later the federal Centers for Disease Control and Preventions reported that a second chemical made up 5 percent of the contents of the leaking tank. It was polyglycol ethers, PPH, less hazardous than the main chemical.
Nanomaterials have emerged recently as a new class of materials. The hazards associated with them are not well known, but studies are starting to track potential hazards. Nanotechnology in general covers engineered structures, devices, and systems that have a length scale between 1 and 100 nanometers. At this size, materials begin to exhibit unique properties that affect physical, chemical, and biological behavior.
Some nanoparticles may be toxic. Early studies show toxicity varying with various chemical and physical properties. Some nanoparticles can penetrate through the skin or move from the respiratory system to other organs. Research is beginning to understand properties leading to specific health effects. Those involved in protecting workers and other from potential harm from nanomaterials must monitor research results. NIOSH continues to publish guidelines 9 for nanomaterials.
Medical diagnostics methods continue to advance rapidly. On January 17, 2014, Google released information about a contact lens-type device that monitors blood sugar levels in the tears of diabetics once per second. The device contains a miniature transmitter that can relay the results continuously to other equipment. The potential value of the instrumentation is high because of the large and growing number of diabetic patients. Studies will define the hazards for wearers.
Researchers have created very thin sheets of silicon that incorporate electronic sensors and circuits. They are flexible and attachable to human skin. They can monitor a range of functions and send information to other equipment.
A highlight of the 2014 Consumer Electronic Show was “wearable electronics.” One example is the computerized display glasses that present visuals just above the normal eye viewing field. The eyeglasses have a display, camera and computer. The model for the show also handled voice commands from the wearer.
Another wearable device is a smart watch. It handles most of the display and computer applications available for smart phones, but only in a smaller package wearable on a wrist. Newer models will add GPS technology and new kinds of applications. These new technologies may have major applications for safety and health. The devices can help track the physical locations of employees, especially if working in hazardous situations. Potentially, the devices can monitor exposures and warn the wearer of pending danger. The devices can make communication with or between workers easy, using hands-free operation. Monitoring patches and wearable electronics can be a major help for certain safety and health functions.
Another highlight of the 2014 Consumer Electronics Show was the expansion of driverless automobile features. A new term is “autonomous car.” A vehicle may operate as a robot using remote control similar to flying drone airplanes. It can automatically maneuver from one location to another in traffic. A vehicle may supplement the limitations of drivers by taking over operations in difficult and frustrating conditions. Audi has produced a Piloted Driving vehicle with front and rear laser to see and monitor traffic and cameras to monitor lane traffic. In addition, the State of Nevada issued a special motor vehicle license to test the autonomous car in real traffic. Such vehicles may help to reduce the high rate of vehicle accidents and resulting injuries and deaths. Such vehicles may allow the operation of vehicles in dangerous off-road mining and materials-handling functions.
