  25. ORGANIZED LABOR • Organized labor has fought for safer working conditions and compensation for injured workers. • Overturned the anti-labor laws: • Fellow-servant rule – employers were not liable for workplace injuries that resulted from negligence of other employees • Contributory negligence – If actions of employees contributed to own injuries • Assumption of Risk – workers who accept a job assume the risks of the job and consequences of the risk COM - Safety Principles

  26. SPECIFIC HEALTH PROBLEMS • Coal Worker’s Pneumoconiosis (Black Lung) • Mercury poisoning • Minimata Japan • 1940s hat making industry in New York • Silicosis • Asbestosis COM - Safety Principles

  27. ACCIDENT PREVENTION PROGRAMS • World Wars I and II – discovered connection between quality and safety • World War II – labor shortage ( women in workplace) • Incentive for employers to create safe workplace Organized safety programs by management introduced the three E’s of safety: • ENGINEERING • EDUCATION • ENFORCEMENT COM - Safety Principles

  28.

AIHA • 1970- Occupational Safety & Health Administration OSHA • 1970 - National Institute of Occupational Safety and Health NIOSH COM - Safety Principles

  29. GROWTH OF PROFESSION • More large companies employing H & S professionals • Influence of OSHA Standards • Greatest growth is in construction and service industries • Increasing emphasis on certified professionals • Public awareness and employee expectations COM - Safety Principles

  30. CHAPTER 1 REVIEW and DISCUSSION • If OSHA went away, what would companies do? • Do Unions do much for Safety and Health anymore? • What other regulation or movement have an impact on safety and health besides OSHA? • What is next in the safety and health field? Review Questions 1. How did workplace tragedies affect the safety movement? 2. Explain the three E’s of safety and how does it apply to safety in the field? Key Terms: Assumption of Risk, Contributory Negligence, Fellow Servant Rule COM - Safety Principles

  31. Chapter 2 Accidents and their Effects • According to National Safety Council: • During a 10 minute speech -- 2 persons will be killed and about 170 will suffer a disabling injury, costing $2,800,000. • On the average -- 11 accidental deaths and 1,030 disabling injuries every hour. • Occupationally – 14 deaths a day • Are Deaths at Work going up or down? COM - Safety Principles

  32. DIRECT AND INDIRECT COSTS OF ACCIDENTS Direct Costs • Lost wages • Medical Expenses • Insurance premiums & administration • Property damage Indirect Costs (Hidden and/or Uninsured Costs) • Production loss • Job -retraining • Downtime and decreased production • Costs of investigator’s time • Overtime wages resulting from incident COM - Safety Principles

  33. COSTS OF ACCIDENTS • $$$$$ spent responding to accidents are $$$ that could have been reinvested in technology, research, facility upgrades etc. • Proactive vs. Reactive • Why should WE prevent accidents? • Economic reasons • Moral reasons • Legal reasons COM - Safety Principles

  34. WORK-RELATEDNESS AND LOST TIME • Not all accidents are “work-related” • Bureau of Labor Statistics (BLS) website provides work-related death/injury statistics • Lost time due to work injuries accounts for approximately 35,000,000 hours/year! • Work-related fatalities and lost time injuries must be recorded for OSHA and BLS. • INCIDENT RATE ? IR = No. recordable injuries / illness X 200,000 Total no. hrs worked by employees/year COM - Safety Principles

  35. WORK INJURIES BY ACCIDENT TYPE • from which the accident resulted, such as: • OVEREXERTION • IMPACT INJURIES ( STRUCK-BY OR CAUGHT BETWEEN) • FALLS • According to the latest BLS report, what are the two leading types of injuries? COM - Safety Principles

  36. DEATH RATES BY INDUSTRY Agencies/ organizations which collect statistics on fatalities include: 1. BLS - Bureau of Labor Statistics 2. NSC - National Safety Council 3. National Center for Health Statistics SIC codes - Standard Industry Classification COM - Safety Principles

  37. PARTS OF BODY INJURED • Important to keep records on the parts of the body injured. Why? • Most frequent injured body parts include: 1. Back 2. Legs and fingers 3. Arms 4. Trunk 5. Hands COM - Safety Principles

  38. REPETITIVE STRESS INJURIES • RSI - Repetitive Stress Injuries is a broad term which includes injuries resulting from cumulative trauma to the soft tissues • MSD - Musculoskeletal Disorders • CTS - Carpal Tunnel Syndrome - common repetitive stress injury to the wrist which effects the median nerve. COM - Safety Principles

  39. ESTIMATING COSTS OF ACCIDENTS • Safety professionals must show COSTS of accidents are greater than the COSTS of prevention. WHY? - CBA • Look at both the INSURED AND UNINSURED (direct and indirect) costs • Calculate the costs • HOW DO YOU GET THE NUMBERS? COM - Safety Principles

  40. CHAPTER 2 REVIEW AND DISCUSSION • How does Lawsuits affect the reasons to increase the safety? • If Company A has a IR of .7 and Company B has a IR of 5.6, does that mean the Company A has a better safety program? • Why is Company C’s IR of 2.5 better than Company’s D 1.3? Review 1. What are some direct and indirect costs? 2. Why is it important for the Safety Professional to estimate accident costs? 3. How are incident rates calculated? Define the following ACRONYMS: BLS, NSC, OSHA, MSD, SIC COM - Safety Principles

  41. Chapter 3 – THEORIES OF ACCIDENT CAUSATION • DOMINO THEORY • HUMAN FACTORS THEORY • ACCIDENT INCIDENT • SYSTEMS THEORY • COMBINATION THEORY • DRUGS, ALCOHOL, AND DEPRESSION • MANAGEMENT FAILURE COM - Safety Principles

  42. THE DOMINO THEORY • 1920’s - Herbert Heinrich, Travelers Insurance • 88% caused by UNSAFE ACTS • 10% caused by UNSAFE CONDITIONS • 2% UNAVOIDABLE • **This has been proven false in many other theories. COM - Safety Principles

  43. HEINRICH’S AXIOMS 1. Injuries result from series of factors, one is the accident itself. 2. Accident occurs only from an unsafe act by a person and/or hazardous condition. 3. Most accidents result from unsafe behavior. 4. Unsafe act does not always immediately result in accident. 5. Reason for unsafe act can guide correction COM - Safety Principles

  44. AXIOM’S CON’T 6. Severity of accident is fortuitous and accident is preventable 7. Best accident prevention = best quality & production techniques 8. Management should assume responsibility for safety. 9. Supervisor is key in prevention 10. Accidents have direct and indirect costs. COM - Safety Principles

  45. 5 DOMINO’S • 5 FACTORS in sequence lead to accident: 1. Ancestry and social environment 2. Fault of person 3. Unsafe act/ Hazardous condition 4. Accident 5. Injury COM - Safety Principles

  46. DOMINO THEORY - 2 POINTS 1. Injuries are caused by the action of preceding factors 2. The removal of the central factor (unsafe act or hazardous condition) negates the action of the preceding factors, thereby preventing accidents and injuries. How do you use this model to prevent accidents? COM - Safety Principles

  47. HUMAN FACTORS THEORY Attributes accidents to chain of events ultimately caused by human error. 1. Overload • Environmental factors • Internal factors • Situational factors 2. Inappropriate response 3. Inappropriate activities COM - Safety Principles

  48. ACCIDENT/INCIDENT THEORY • An extension of H.F. Theory • Developed by Dan Petersen • New elements ie. “ergonomic traps” • Conscious or unconscious decision to err • Causal relationship between management decision, management behavior and safety. • MULTIPLE CAUSES COM - Safety Principles

  49. SYSTEMS THEORY • A system is a group of interrelated components that interact together to form a whole. • Likelihood of an accident determined by how these components interact. • Interacting components: • Machine • Person • Environment COM - Safety Principles

  50. RISK DECISIONS 1. JOB REQUIREMENTS 2. WORKER ABILITY & LIMITATION 3. GAIN IF TASK IS ACCOMPLISHED 4. LOSS IF ATTEMPTED TASK FAILS 5. LOSS IF TASK IS NOT ATTEMPTED What is you HAD to do a job that is extremely high hazard? COM - Safety Principles
