ASF Risk Management & Mitigation 5

Question 1

A technician discovers that an oven's thermal limiter has been bypassed with a jumper wire by a previous technician. What is the risk and correct action?

Accepted Answer

Remove the jumper, replace the thermal limiter, and document the unsafe modification found

Answer

A bypassed thermal limiter removes the appliance's primary overheating protection, creating a serious fire and burn risk that must be corrected immediately.

Question 2

What is the significance of a 'hierarchy of controls' in appliance service risk management?

Accepted Answer

It provides a prioritized framework for selecting the most effective hazard control method

Answer

The hierarchy of controls ranks hazard control methods from most to least effective: elimination, substitution, engineering controls, administrative controls, and PPE.

Question 3

A technician is servicing a range hood and finds the grease filters have not been cleaned in years, with heavy grease buildup. What risk does this present beyond poor ventilation?

Accepted Answer

Fire risk from ignition of accumulated grease if heat or a spark reaches the filter

Answer

Heavy grease accumulation in range hood filters is a significant fire hazard because grease is flammable and can ignite from cooking flames or sparks.

Question 4

When transporting a recovered refrigerant cylinder in a service vehicle, which safety practice is REQUIRED?

Accepted Answer

Secure the cylinder upright in a ventilated area and keep it away from heat sources

Answer

Refrigerant cylinders must be secured to prevent tipping, kept in ventilated spaces, and away from heat to prevent pressure buildup and potential rupture.

Question 5

A technician notices that a customer has installed an appliance closer to combustible materials than the manufacturer's clearance specification. What should the technician do?

Accepted Answer

Document the hazard, inform the customer of the fire risk and required clearance, and note it in the service record

Answer

Improper installation clearances create fire risks; the technician must inform the customer and document the hazard as part of their professional duty of care.
