1. University of Minnesota Duluth Job Hazard Analysis Assessing Risk & Eliminating Hazards Prepared by Environmental Health and Safety Office 218-726-7139

2. What is a Job Hazard Analysis? • A technique to identify hazards, and prevents accidents before they occur. • It focuses on the relationship between the worker, thetask, the tools, the work environmentand resultingconsequences. When all uncontrolled hazards and resulting effects/harm are identified, safe SOP (Standard Operating Procedure) summarizing steps to be taken to eliminate/reduce hazards to an acceptable risk level will be implemented.

3. What is a Hazard? A hazard is the potential for harm! • Any source with the potential to cause damage, harm, or adverse (health) effects on something or someone under certain conditions at work. • The adverse effect or harm is caused to individuals (as health effects), or to organizations (as property damage, or equipment loss).

4. Hazard Types • Biological- bacteria, viruses, insects, plants, birds, animals, and humans, etc., • Chemical- depends on the physical, chemical and toxic properties of the chemical. • Ergonomic- repetitive movements, improper set up of workstation, etc., • Physical- radiation, magnetic fields, pressure extremes (high pressure or vacuum), noise, etc, • Psychosocial- stress, violence, etc., • Safety- slipping/tripping hazards, lack of machine guarding, equipment malfunctions or breakdowns

6. Other Examples of Hazards • Noise levels (>85 dBA 8 hr TWA) that result in hearing damage or inability to communicate safety-critical information. • Struck By Accelerated object that strikes the body causing injury or death. (Examples are falling objects and Accelerated projectiles.) • Fire Harm to individuals, or Damage to property

7. A word about risk? [Risk is the Chance of Loss!] The probability, or likelihood that an adverse event will occur in which: A person (worker) will be harmed or experience an adverse health effect if exposed to a hazard, or The organization (employer) will sustain property damage, equipment loss, and therefore an economical setback.

8. How to identify hazards? • What can go wrong? • What are the consequences? • How likely is it that harm will occur? • Where it is happening (environment)? • Who or what it is happening to (exposure)? • What precipitates the hazard (triggers)? • Are there other contributing factors?

9. How are Appropriate Preventive Measures Determined? Eliminating the hazard : • Through engineering controls, such as increasing ventilation • Product substitution, or (using les toxic materials) • Changing equipment or tools. Containing the hazard • Separating the employee from the hazard with enclosures, guards, booths, etc. Administrative measures • Revising work procedures, (changing the sequence of steps or adding steps, such as lockout/ tagout). • Retraining employees Choosing Adequate Personal Protective Equipment (PPE) (This is the least effective control measure, and should be used only if other solutions are not possible)
