ASF Risk Management & Mitigation 4

Question 1

A technician replaces a gas valve on a range and uses a soap solution to check for leaks. Small bubbles appear at one fitting. What is the correct next step?

Accepted Answer

Re-tighten or reseal the fitting until no bubbles appear, then retest

Answer

Any bubbling during a gas leak test indicates an active leak that must be corrected and retested before the appliance can be used.

Question 2

Which of the following is an example of a 'residual risk' after safety controls have been implemented during appliance service?

Accepted Answer

The possibility of injury remaining after all practical controls are in place

Answer

Residual risk is the level of risk that remains after all feasible safety controls have been applied — it can never be completely eliminated.

Question 3

When a technician identifies that a customer's appliance has a recalled component, what is the MOST appropriate action?

Accepted Answer

Inform the customer of the recall, advise discontinuing use, and report to the manufacturer or CPSC as required

Answer

Federal recall obligations require notifying the customer, recommending the appliance not be used, and following the manufacturer's recall procedure or CPSC guidance.

Question 4

A technician arrives at a service call and finds the appliance is plugged into a heavily damaged power cord with exposed wiring. What is the CORRECT first action?

Accepted Answer

Unplug the appliance using the plug body (not the cord) or shut off the circuit breaker

Answer

Exposed wiring is an immediate shock and fire hazard; the circuit must be de-energized safely before any work can proceed.

Question 5

What is the PRIMARY goal of conducting a pre-task risk assessment before beginning appliance service?

Accepted Answer

To identify hazards and implement controls before work begins

Answer

A pre-task risk assessment proactively identifies potential hazards so controls can be established before the technician is exposed to them.
