1 PATH216 Mohamed M. B. Alnoor SAFETY and INJURY PREVENTION

2  Definition of injury  Epidemiologic Triangle  Causes of Accident  Impact of injury and accidents  Prevention of Injury CONTENT

3  Injury: Physical damage due to transfer of energy Definition: kinetic thermal chemical electrical radiant Over a period of time: “exposure” either acute or chronic INJURY

4  Accident: An unexpected occurrence, happening by chance  Injury: a definable, understandable, predictable, preventable, correctable event, with specific risks for occurrence. Injury, Not Accident! Definition: INJURY  A result of poorly managed risk

5 Epidemiologic Triangle “Prevention is the vaccine for the disease of injury.” Environment Host AGENT A causal relationship! Definition: INJURY  “Disease of injury” concept

6 Causes of Accident Accidents are caused by: – Unsafe acts – Unsafe conditions Most difficult to address Changing behavior isn’t easy Best prevented by developing a “safety culture” INJURY

7 Unsafe Conditions  Easiest to correct (and very cost effective)  Easiest to prevent Safety audits Safety inspections Maintenance schedules for equipment Encouraging employee reporting Good housekeeping INJURY Causes of Accident

20 Categories of injury prevention:  Primary prevention:  Secondary prevention:  Tertiary prevention: Eliminate the event Diminish effect Improve outcomes INJURY Injury Prevention PRE EVENT POST EVENT EVENT

21  Direct Costs Medical Costs(including worker’s compensation) Indemnity Payments  Indirect Costs Time Lost (by worker and supervisor) Schedule delays Training new employees Cleanup time / equipment repairs Legal fees Cost of Accidents INJURY

22 The Iceberg Effect Cost of Accidents On average, the indirect costs of accidents exceed the direct costs by a 4:1 ratio INJURY

23 Examples of effective injury prevention: Highway speed limits Apartment window guards Smoke detectors Child passenger restraint laws “Cycle” helmet laws Strategies of injury prevention: INJURY Injury Prevention

24  Establish accountability for safety  Define safety responsibilities Safety Cultures INJURY Injury Prevention

25  Establish accountability for safety Safety Cultures INJURY Injury Prevention Employees should be evaluated on their safety Performance: Doing a job correctly includes doing it safely

26  Define safety responsibilities Employee responsibilities include  Maintaining good housekeeping  Recognizing and reporting safety hazards  Using personal protective equipment (PPE) Safety Cultures INJURY Injury Prevention

27  Providing access to information  Providing personal protective equipment  Providing training Safety Cultures INJURY Injury Prevention  Define safety responsibilities Employer responsibilities include
