There has been an awareness of industrial hygiene since antiquity. The environment and its relation to worker health was recognized as early as the fourth century BC when Hippocrates noted lead toxicity in the mining industry. In the first century AD, Pliny the Elder, a Roman scholar, perceived health risks to those working with zinc and sulfur. He devised a face mask made from an animal bladder to protect workers from exposure to dust and lead fumes. In the second century AD, the Greek physician, Galen, accurately described the pathology of lead poisoning and also recognized the hazardous exposures of copper miners to acid mists.
Industrial safety in the United States as we know it today did not begin to take shape until the early 20th century. Before that, many risked their lives daily going to work in industrial settings that included mines, construction, mills and manufacturing. In today's world, work safety statistics are usually measured by the number of injuries or deaths that take place yearly. Prior to 1900 these type of statistics are hard to come by, in part because it appeared that no one cared enough to make tracking on-the-job injuries and deaths a priority.Lecture Materials
Lesson 3: Breakdown of forces in space
In physics, a force is any influence which tends to change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.
Lesson 4: SAFETY AND INDUSTRIAL HYGIENE IV
Please note: The term incident is used in some situations and jurisdictions to cover both an "accident" and "incident". It is argued that the word "accident" implies that the event was related to fate or chance. When the root cause is determined, it is usually found that many events were predictable and could have been prevented if the right actions were taken -- making the event not one of fate or chance (thus, the word incident is used). For simplicity, we will use the term accident to mean all of the above events.
Lesson 5: SAFETY OF OPERATIONS
Crushed hands and arms, severed fingers, blindness -- the list of possible machinery-related injuries is as long as it is horrifying. There seem to be as many hazards created by moving machine parts as there are types of machines. Safeguards are essential for protecting workers from needless and preventable injuries. A good rule to remember is: Any machine part, function, or process which many cause injury must be safeguarded. When the operation of a machine or accidental contact with it can injure the operator or others in the vicinity, the hazards must be either controlled or eliminated.Lecture Materials
Lesson 6: SAFETY OF OPERATION II
Electrically powered equipment, such as hot plates, stirrers, vacuum pumps , electrophoresis apparatus, lasers, heating mantles, ultrasonicators, power supplies, and microwave ovens are essential elements of many word areas. These devices can pose a significant hazard to workers, particularly when mishandled or not maintained. Many electrical devices have high voltage or high power requirements, carrying even more risk. Large capacitors found in many laser flash lamps and other systems are capable of storing lethal amounts of electrical energy and pose a serious danger even if the power source has been disconnected.Lecture Materials
Lesson 7: SAFETY OF OPERATIONS III
Radioactivity naturally decays over time, so radioactive waste has to be isolated and confined in appropriate disposal facilities for a sufficient period of time until it no longer poses a hazard. The period of time waste must be stored depends on the type of waste and radioactive isotopes. It can range from a few days for very short-lived isotopes to millions of years for spent nuclear fuel. Current major approaches to managing radioactive waste have been segregation and storage for short-lived waste, near-surface disposal for low and some intermediate level waste, and deep burial or partitioning / transmutation for the high-level waste.Lecture Materials
Lesson 8: Chemical Toxicity
Toxicology is the study of the nature and action of chemical substances on living systems. Toxicity is the ability of a chemical molecule or compound to produce injury once it reaches a susceptible site in or on the body. Hazard is the probability or likelihood that injury will occur considering the manner in which the substance is used..Lecture Materials
Lesson 9: PROGRAM OF SAFETY AND INDUSTRIAL HYGIENE
An OSHA Safety Plan is a written document that describes the process for identifying the physical and health hazards that could harm workers, procedures to prevent accidents, and steps to take when accidents occur. The written safety plan is your blueprint for keeping workers safe. Many organizations compile their activity-specific safety plans into a single safety manual.Lecture Materials
Lesson 10: ECONOMIC ANALYSIS OF SAFETY AND HYGIENE
The European Agency for Safety and Health at Work estimates that every year about 5,500 people are killed in the workplace across the European Union, with another 4.5 million accidents resulting in more than three days absence from work (amounting to around 146 million working days lost). These accidents are estimated to cost the EU about 20 billion euro. The problem affects all sectors of the economy and is particularly acute in enterprises with less than 50 workers. Accidents and occupational diseases can give rise to heavy costs to the company, particularly small companies. Preventing work accidents, occupational injuries and diseases has more benefits than just reducing damages: it has also been shown to be a contributory factor in improving company performance.Lecture Materials
