THE SAFETY AND HEALTH MOVEMENTTHE SAFETY AND HEALTH MOVEMENT

– In 1907, more than 3,200 people were killed in mining accidents.

• Legislation, precedent, and public opinion allfavored management.– There were few protections for workers’ safety.

• Working conditions for industrial employees today



g p y yhave improved significantly.– Chance of worker death in an industrial accident

is less than half of what it was 60 years ago.


DEVELOPMENTS BEFORE THE INDUSTRIAL DEVELOPMENTS BEFORE THE INDUSTRIAL REVOLUTIONREVOLUTION

• Understanding the past can help safety & health professionals examine the present and futurewith a sense of perspective and continuitywith a sense of perspective and continuity.

• Modern developments in health & safety are partof the long continuum of developments.– Beginning in the days of the ancient Babylonians.

• Circa 2000 BC, their ruler developed his Code of Hammurabi, which encompassed all the laws of



Hammurabi, which encompassed all the laws ofthe land at that time.– Showed Hammurabi to be a just ruler, and set a

precedent followed by other Mesopotamian kings.

• Significance of the code from the perspective of safety & health are clauses dealing with injuries.– Allowable fees for physicians & monetary damages– Allowable fees for physicians & monetary damages

assessed against those who injured others.

• Later emerged in the industrious Egyptian civilization.– Much labor was provided by slaves & slaves were

not treated well—unless it suited the needs ofE ti t k t



Egyptian taskmasters.



• To ensure maintenance of a workforce to build a huge temple bearing his name, Rameses II createdan industrial medical service to care for the workersan industrial medical service to care for the workers.– They were required to bathe daily in the Nile and given

regular medical examinations, & sick workers isolated.

• The Romans were vitally concerned with safety & health, as seen from their construction projects.– Aqueducts, sewerage systems, public baths, latrines,



and well-ventilated houses.

• In 1567, Philippus Aureolus produced a treatiseon the pulmonary diseases of miners.– Covered diseases of smelter workers & metallurgists– Covered diseases of smelter workers & metallurgists.

• Diseases associated with handling/exposure to mercury.

• Around the same time, Georgius Agricola published De Re Metallica, emphasizing need for ventilation in mines, showing devices to bring fresh air into mines.

• The eighteenth century saw Bernardino Ramazzini,

by workers and their occupations.



• The Industrial Revolution changed forever the methods of producing goods, summarized as: – Introduction of inanimate power (i e steam power) to– Introduction of inanimate power (i.e., steam power) to

replace people and animal power.

– Substitution of machines for people.

– Introduction of new methods for converting raw materials.

– Organization/specialization of work, resulting in a division of labor.

• These changes necessitated a greater focusing of attention on the safety and health of workers.– Steam power increased markedly the potential for– Steam power increased markedly the potential for

life-threatening injuries, as did machines.

– The new methods used for converting raw materialsalso introduced new risks of injuries and diseases.

– Specialization, by increasing the likelihood of boredomand inattentiveness, also made the workplace a more dangerous environment

MILESTONES IN THE SAFETY MOVEMENT MILESTONES IN THE SAFETY MOVEMENT

• The safety movement traces its roots to England.– In the Industrial Revolution, child labor in factories was

common.common.

– Hours were long, work hard, and conditions often unhealthy & unsafe.

• After an outbreak of fever among children workingin their cotton mills, people of Manchester, England, demanded better factory working conditionsdemanded better factory working conditions.– In 1802 the Health & Morals of Apprentices Act passed.

• Marked the beginning of governmental involvement in workplace safety.





• When the industrial sector began to grow in the US, hazardous working conditions were commonplace.– Factory inspection began in Massachusetts in 1867– Factory inspection began in Massachusetts in 1867.

– In 1868, the first barrier safeguard was patented.

– In 1869, the Pennsylvania legislature passed a mine safety law requiring two exits from all mines.

– The Bureau of Labor Statistics (BLS) was started in 1869.

– In 1877, the Massachusetts legislature passed a law i i f d f h d hi



requiring safeguards for hazardous machinery.

– 1877 also saw passage of the Employer’s Liability Law.• Establishing potential for employer liability in workplace

accidents.

• Following the explosion, a committee of managers formed to investigate and make recommendations.– Used as the basis for development of a safety program

considered to be the first in American industry.





• Around 1900, Frederick Taylor began studying efficiency in manufacturing, and drew a connection between lost personnel time & management policiesbetween lost personnel time & management policies and procedures.

• In 1907, the U.S. Dept. of the Interior created the Bureau of Mines to investigate accidents, examine health hazards, and make recommendations for improvements.



– In 1908 an early form of workers’ compensation was introduced in the United States.

• Workers’ compensation actually had its beginnings in Germany, and soon spread through Europe.

• Workers’ compensation made great strides in the• Workers compensation made great strides in the US when Wisconsin passed the first effective workers’ compensation law in 1911.– Today, all 50 states have some form of workers’

compensation.





• The Association of Iron and Steel Electrical Engineers (AISEE), formed in the early 1900s, pressed for a national conference on safetypressed for a national conference on safety.– The first meeting of the Cooperative Safety Congress

(CSC) took place in Milwaukee in 1912.

• A year after the initial meeting of the CSC, the National Council of Industrial Safety (NCIS) was established in Chicago.



– In 1915, this organization changed its name to the National Safety Council, now the premier safety organization in the United States.

• From 1918 through the 1950s, the federal government encouraged contractors toimplement & maintain a safe work environmentimplement & maintain a safe work environment.

• Industry in the US arrived at two critical conclusions– There is a definite connection between quality & safety.

– Off-the-job accidents have a negative impact on productivity.





• The 1960s saw the passage of a flurry of legislation promoting workplace safety.– The Service Contract Act– The Service Contract Act

– The Federal Metal & Nonmetallic Mine Safety Act.

– The Federal Coal Mine and Safety Act

– The Contract Workers and Safety Standards Act.

• These laws applied to a limited audience of workers, and the injury & death toll due to industrial mishaps



j y pwas still too high.– In the late 1960s, more than 14,000 employees

were killed annually in connection with their jobs.

TRAGEDIES THAT HAVE CHANGED THETRAGEDIES THAT HAVE CHANGED THESAFETY MOVEMENTSAFETY MOVEMENT

• Safety & health tragedies in the workplace greatly accelerated the pace of the safety movement inthe USthe US.





• Hawk’s Nest Tragedy - solidified public opinion in favor of protecting workers from the debilitating disease silicosisdisease silicosis.

• A company contracted to drill a passage through a mountain in the Hawk’s Nest region of West Virginia.– Workers spent as many as 10 hours per day breathing

dust created by drilling and blasting.• This mountain had an unusually high silica content.



• Silicosis normally takes 10 to 30 years to show up.– Hawk’s Nest workers began dying in as little as a year.

• By the time the project was completed, hundreds had died.

1/11/2011

12



• This tragedy & resulting public outcry led a groupof companies to form the Air Hygiene Foundation.– To research & develop standards for work in dusty areas– To research & develop standards for work in dusty areas.

• The US Department of Labor helped make silicosis a compensable disease in most states.– Approximately 1 million workers in the US are

still exposed to silica every year.• 250 people die annually from silicosis.





• Asbestos Menace - in 1964, Dr. Irving J. Selikoff told a conference on biological effects of asbestos that the widely used material was killing workersthat the widely used material was killing workers.– Asbestos was once considered a “miracle” fiber.

• At the time of Selikoff’s findings, asbestos was one of the most widely used materials in the US.– Found in homes, schools, offices, factories, ships, and

even in the filters of cigarettes.



• This conference changed how Americans viewed not just asbestos, but workplace hazards in general.– Selikoff was the first to link asbestos to lung cancer and

respiratory diseases.

1/11/2011

• Selikoff continued to study the effects of asbestos exposure from 1967 to 1986.– In the 1970s-80s asbestos became a controlled material– In the 1970s-80s, asbestos became a controlled material.

• Regulations governing use, standards for exposure were established, and asbestos-related lawsuits changed how industry dealt with this tragic material.





• Bhopal Tragedy - On Dec. 3, 1984, over 40 tonsof methyl isocyanate (MIC) & other gases, including hydrogen cyanide leaked into north Bhopal Indiahydrogen cyanide, leaked into north Bhopal, India.– Killing more than 3,000 people in its aftermath.

• It was discovered the protective equipment that could have halted impending disaster was notin full working order.

• The International Medical Commission found that



The International Medical Commission found thatas many as 50,000 people were exposed, andmay still suffer disability as a result.– This disaster shocked the world.

• Union Carbide Corporation, owner of the plant, was accused of many things, including: – Criminal negligence– Criminal negligence.

– Corporate prejudice - choosing poverty-stricken Bhopal, on the assumption few would care if anything went wrong.

– Avoidance - putting its plant in Bhopal to avoid stricter US safety & health standards.

• In February 1989, India’s Supreme Court ordered U i C bid I di Ltd t $470 illi i



Union Carbide India Ltd., to pay $470 million in compensatory damages.– Funds were paid to the Indian government to be

used to compensate the victims.


ROLE OF ORGANIZED LABOR ROLE OF ORGANIZED LABOR

• Organized labor has played a crucial role in the development of the safety movement in the US.– Many of the earliest safety developments were the– Many of the earliest safety developments were the

result of long, hard-fought battles by organized labor.

• A dissenting view holds union involvement actually slowed development of the safety movement.– Unions allowed demands for safer working conditions to

become entangled with their demands for better wages.



• As a result, they met with resistance from management.

1/11/2011

15



• A most important contribution of organized laborto the safety movement was their work to overturn antilabor laws relating to safety in the workplaceantilabor laws relating to safety in the workplace– The fellow servant rule held that employers were

not liable for workplace injuries resulting fromnegligence of other employees.

– Contributory negligence absolved an employer if the actions of employees contributed to their own injuries.

Assumption of risk was based on the theory that people



– Assumption of risk was based on the theory that people who accept a job assume the risks that go with it.



• Because the overwhelming majority of industrial accidents involve negligence on the part of one or more workers employers had little to worry aboutmore workers, employers had little to worry about.– And little incentive to promote a safe work environment.

• Organized labor played a crucial role in bringing deplorable working conditions to public attention.– Awareness & outrage eventually led to employer-biased

laws being overturned in all states except one.



• In New Hampshire, the fellow servant rule still applies.

ROLE OF SPECIFIC HEALTH PROBLEMS ROLE OF SPECIFIC HEALTH PROBLEMS

• Specific health problems tied to workplace hazards have played significant roles in the development of the modern safety and health movementthe modern safety and health movement.





• Lung disease in coal miners was a major problem in the 1800s, particularly in Great Britain, where much of the Western world’s coal was mined at the timeof the Western world s coal was mined at the time.

• Anthrocosis, or the black spit, persisted from the early 1800s, when first identified, until about 1875. – It was finally eliminated by safety &health measures.

• By the early 1940s, British scientists were usingthe term coal-miner’s pneumoconiosis, or CWP,



the term coal miner s pneumoconiosis, or CWP,to describe a disease suffered by many miners.– Designated a separate, compensable disease in 1943.

1/11/2011

• An West Virginia coal mine explosion that killed 78 miners focused attention on mining health & safety.– Congress passes Coal Mine Health & Safety Act 1969– Congress passes Coal Mine Health & Safety Act, 1969.

• Amended 1977/78 to broaden scope of coverage.

• Congress held hearings on silicosis in 1936, and business, industry & government representatives attended the National Silicosis Conference.– Finding that silica dust particulates did, in fact,



cause silicosis.



• Mercury poisoning was first noticed among citizens of a Japanese fishing village in the early 1930s.– A chemical plant near the village Minamata periodically– A chemical plant near the village Minamata periodically

dumped methyl mercury into the bay that was the village’s primary source of food.

– The citizens ingested hazardous dosages of mercury every time they ate fish from the bay.



1/11/2011

• Mercury poisoning became an issue in the US after a 1940s study on New York’s hat-making industry.– Many workers displayed the same types of symptoms– Many workers displayed the same types of symptoms

as the citizens of Minamata, Japan.• A study linked mercury nitrate used in hat production.

• As a result, use of this hazardous chemical in the hat-making industry was stopped.– A suitable substitute—hydrogen peroxide—was found.





• By the time it was determined that asbestos is a hazardous material, the fibers of which can cause asbestosis or lung cancer (mesothelioma)asbestosis or lung cancer (mesothelioma), thousands of buildings contained the substance.– As these buildings began to age, the asbestos—

particularly that used to insulate pipes—breaks down.

– As asbestos breaks down, it releases dangerous microscopic fibers into the air.

Th fib h d th t i b t



• The fibers are so hazardous that removing asbestos from old buildings has become a highly specialized task requiring special equipment & training.

– Personal protective equipment.

– Redundancy, timed replacements, etc.





• Individual components of broader safety programs have evolved since the late 1800s.– Early employers had little concern for worker safety– Early employers had little concern for worker safety.

• And little incentive to be concerned.

– Between World War I & World War II, industry discovered the connection between quality & safety.

– World War II labor shortages created a greater openness toward giving safety the serious consideration it deserved.
