Methods Of Hazard Identification

What Is Hazard Identification?

Hazard Identification is a method used to determine attainable things where people may be exposed to injury, sickness, or disease. Moreover,

  • It is a part of risk assessment;
  • Once the hazards are identified, proper measures must be taken to eliminate them.

The Best 6 Methods of Hazard Identification

  1. Formal Safety Audits
  2. Workplace Inspections Observation
  3. Incident Investigations
  4. Historical Safety Records
  5. Safety Committee Recommendations
  6. Employee Complaints Suggestions


Core Concept of Hazard

A hazard could be a state of affairs that poses a threat to life, health, property, or the environment.


Hazard = Possibility (P) + No Consequence (C) or, Possibility x No Consequence.


Most hazards are inactive or potential; it is only theoretical risk of harm. But, once a hazard becomes “active”, it will produce an associate degree of emergency.

Hazards and possibilities interact together to create risk.

Methods Of Hazard Identification

Major Types

  • Corrosives – cause tissue injury and burns on contact with skin or eyes
  • Primary Irritants – cause intense redness/swelling of skin or eyes on contact. No permanent tissue injury
  • Sensitizers – cause allergic skin or lung reaction

  • Carcinogens – might cause cancer
  • Teratogens – might cause birth defects
  • Organ-Specific Hazards – injury to specific organ systems like the liver or lungs.

Labels – Reactivity Labels – Special Hazard
▪ The flammability of liquids defined by their flash-point

-the lowest temperature at which a fuel-air mixture present above the surface of a liquid will ignite if an ignition source is introduced.

▪ 21-55    Flammable

▪ Highly flammable

▪ Extremely flammable

What the letters show

▪ OX = Oxidizer
