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 important to identify hazards and assess the associated ris...read more

The hierarchy of control is a systematic approach to managing workplace hazards.

• Elimination: Completely remove the hazard from the workplace.

• Substitution: Replace the hazard with a less hazardous alternative.

• Engineering controls: Modify the workplace or equipment to reduce the risk.

• Administrative controls: Implement policies, procedures, and training to minimize exposure.

• Personal protective equipment (PPE): Provide protective gear to reduce the risk of exposure.

• Example: Elimi...read more

Pyrophoric material is a substance that ignites spontaneously in air at or below room temperature.

• Pyrophoric materials are highly reactive and can ignite without an external ignition source.

• They can ignite upon contact with air, moisture, or other substances.

• Examples of pyrophoric materials include white phosphorus, alkali metals, and certain organometallic compounds.

C.S.I.D.L.H stands for Control of Substances Hazardous to Health. It is a set of regulations that aim to protect workers from exposure to hazardous substances.

• C.S.I.D.L.H is a set of regulations in the field of occupational health and safety.

• It requires employers to assess and control the risks associated with hazardous substances in the workplace.

• The regulations cover a wide range of substances, including chemicals, fumes, dusts, and biological agents.

• Employers must provide ...read more

Hierarchy of Hazard controls refers to a systematic approach to eliminate or minimize workplace hazards.

• Hierarchy of Hazard controls is a framework used to prioritize and implement measures to control workplace hazards.
