• Hazard is a potential source of harm or danger that can cause an adverse effect.

• Risks and hazards can be physical, chemical, biological, ergonomic, or psychosocial in nature.

• Examples of risks/hazards inclu...read more

Risk is the product of the probability of a hazard resulting in an adverse event, times the severity of the event.

• Risk is calculated by multiplying the likelihood of an adverse event occurring by the severity of the event.

• Hazards are anything that has the potential to cause harm.

• If there is no hazard, there is no risk.

• Examples of hazards include chemicals, machinery, and environmental factors.

• As an HSE Officer, it is i...read more
