G3 - Gas Technician Level 3 Workplace Safety and PPE Questions and Answers

Question 1

A gas technician is preparing to service a rooftop unit. Which of the following PPE is essential for protection against potential falling objects and impact hazards?

Accepted Answer

A CSA-certified hard hat

Answer

A CSA-certified hard hat is the primary piece of personal protective equipment designed to protect the head from impact from falling objects, which is a significant risk when working on construction sites or below areas where overhead work is being performed. While other PPE is important, the hard hat specifically addresses the hazard of falling objects.

Question 2

When drilling into masonry to run a gas line, a technician is exposed to flying particles and dust. According to CSA Standard Z94.3, what is the most appropriate eye protection for this specific task?

Accepted Answer

A full-face shield worn over safety glasses

Answer

A full-face shield worn over safety glasses offers the highest level of protection against the high-velocity flying particles and pervasive dust generated by drilling into masonry. Safety glasses protect the eyes, while the face shield protects the entire face from impact and splashes. CSA Standard Z94.3 recommends this combination for high-hazard tasks.

Question 3

A technician needs to enter a crawl space to inspect a gas line. Atmospheric testing reveals a potentially hazardous atmosphere. What is a critical safety procedure that must be followed according to Ontario's confined space regulations?

Accepted Answer

Having a trained attendant stationed outside the space for monitoring and communication.

Answer

Ontario Regulation 632/05 requires a trained attendant to be stationed outside a confined space at all times during entry. The attendant's role is to monitor the entrant, maintain communication, and initiate rescue procedures if necessary. This is a non-negotiable part of the confined space entry plan.

Question 4

Before starting maintenance on a gas-fired boiler, the technician must isolate it from the electrical supply. What is the correct procedure to ensure the equipment cannot be accidentally re-energized?

Accepted Answer

Applying a Lockout/Tagout (LOTO) device to the electrical breaker.

Answer

The proper and safest method for isolating electrical energy is to use a Lockout/Tagout (LOTO) procedure. This involves shutting off the breaker, applying a personal lock to prevent it from being turned back on, and attaching a tag to inform others that work is in progress. Simply turning off a switch is insufficient as it can be easily turned back on.

Question 5

While handling pipe sealant and cleaning solvents, a gas technician should consult which document to understand the specific health hazards and required protective measures?

Accepted Answer

The product's Safety Data Sheet (SDS).

Answer

The Safety Data Sheet (SDS), a key component of the Workplace Hazardous Materials Information System (WHMIS), provides detailed information about a hazardous product's potential health effects, physical and chemical properties, and safe handling procedures, including required PPE.
