Answer

It violates OSHA confined-space entry standards

Answer

It contaminates local groundwater and soil

Question 3

Which type of refrigerant release is considered 'de minimis' and is NOT prohibited by EPA 608?

Accepted Answer

Small unavoidable releases when attaching or detaching service hoses

Answer

Venting refrigerant deliberately to speed up a service repair

Answer

Releasing refrigerant from a system that is overfilled

Answer

Question 4

Which statement about the reuse of recovered refrigerant is TRUE under EPA 608?

Accepted Answer

Recovered refrigerant can be returned to the same system or equipment owned by the same customer without further treatment

Answer

All recovered refrigerant must be tested and reclaimed before any reuse

Question 5

What must a technician do if recovery equipment is unavailable at a job site?

Accepted Answer

Answer

Transfer refrigerant between systems directly without recovery equipment

Answer

Apply for a temporary EPA exemption before proceeding

Question 6

Which recovery method is typically fastest when servicing large commercial refrigeration systems with substantial refrigerant charges?

Accepted Answer

Liquid recovery or the push-pull method

Answer

Vapor-only recovery through the low-side service port

Answer

System-dependent passive recovery using system pressure alone

Answer

Single-pass vapor recovery through an external filter-drier

Question 7

After recovering refrigerant, how should a technician properly handle and store the recovery cylinder?

Accepted Answer

Label it with the refrigerant type and store it upright in a cool, well-ventilated area away from heat sources

Answer

Store it upside down to prevent moisture from entering the valve

Answer

Fill it to 100% capacity to maximize storage before transport

Answer

Leave the service valves open to prevent internal pressure buildup
