Free CESCO Risk Assessment & Hazard Control Questions and Answers

Question 1

What is the primary purpose of a risk assessment?

Accepted Answer

To identify hazards and evaluate risks

Answer

The primary purpose of a risk assessment is to systematically identify potential hazards in the workplace and then evaluate the associated risks. This process helps determine the likelihood and severity of harm, allowing organizations to prioritize and implement effective control measures to mitigate those risks.

Question 2

Which step comes first in hazard control?

Accepted Answer

Elimination or substitution

Answer

In the hierarchy of controls, elimination or substitution is the first and most effective step in hazard control. Elimination involves physically removing the hazard, while substitution replaces the hazardous material or process with a less dangerous one, thereby preventing exposure at its source.

Question 3

What is the hierarchy of controls?

Accepted Answer

Ranking controls by effectiveness

Answer

The hierarchy of controls is a systematic approach to ranking hazard control methods based on their effectiveness in reducing or eliminating risks. It prioritizes controls from most effective (elimination, substitution) to least effective (PPE), guiding organizations to implement the strongest possible protective measures.

Question 4

What is an engineering control?

Accepted Answer

Physical modifications for safety

Answer

An engineering control involves making physical modifications to the workplace, equipment, or process to reduce or eliminate hazards. Examples include installing machine guards, ventilation systems, or ergonomic workstations, which are highly effective as they control the hazard at the source rather than relying on worker behavior.

Question 5

What is the role of personal protective equipment (PPE)?

Accepted Answer

To protect workers when hazards remain

Answer

The role of Personal Protective Equipment (PPE) is to protect workers when hazards cannot be entirely eliminated or controlled through engineering or administrative measures. PPE acts as a last line of defense, minimizing exposure to risks by providing a barrier between the worker and the hazard, such as safety glasses, gloves, or respirators.
