Safety Trained Supervisor Hazard Control Principles Questions and Answers 1

Question 1

According to the hierarchy of controls, which of the following is considered the MOST effective method for controlling a hazard?

Accepted Answer

Elimination

Answer

The hierarchy of controls ranks hazard control methods from most to least effective. Elimination, which physically removes the hazard, is at the top and is considered the most effective method because it removes the risk of exposure entirely.

Question 2

A supervisor at a construction site observes workers being exposed to loud noise from a piece of machinery. Implementing a 'buy quiet' program and purchasing newer, quieter equipment is an example of which type of hazard control?

Accepted Answer

Substitution

Answer

Substitution involves replacing a hazardous material or process with a less hazardous one. In this scenario, replacing the noisy equipment with a quieter model is a direct example of substitution.

Question 3

Which of the following is an example of an administrative control for hazard management?

Accepted Answer

Rotating workers through a high-noise area to limit exposure time.

Answer

Administrative controls are changes in work procedures or policies to reduce exposure. Job rotation is a classic example of an administrative control that limits the duration of a worker's exposure to a hazard.

Question 4

A manufacturing facility installs a local exhaust ventilation (LEV) system to capture welding fumes at the source. This is an example of what type of hazard control?

Accepted Answer

Engineering Control

Answer

Engineering controls are physical changes to the work environment or equipment to isolate workers from hazards. A local exhaust ventilation system is a prime example of an engineering control because it physically removes the hazardous fumes from the breathing zone of the worker.

Question 5

In the context of the hierarchy of controls, Personal Protective Equipment (PPE) is considered the last line of defense. When is it most appropriate to rely on PPE?

Accepted Answer

When engineering and administrative controls are not feasible or do not provide sufficient protection.

Answer

PPE is considered the least effective control and should be used as a last resort. It is appropriate when higher-level controls like elimination, substitution, and engineering controls are not feasible, or to supplement other controls that do not fully eliminate the risk.
