Question 1

What is the purpose of lockout/tagout before applicable service work?

Authorize deliberate venting Prevent unexpected energization or startup Replace recovery requirements Set the refrigerant's saturation temperature

Question 2

How should recovery cylinders be secured in a service vehicle?

Unrestrained on a seat Against movement in the required orientation Loose beside sharp tools Suspended by their valves

Question 3

Who must perform reclamation for refrigerant sold as reclaimed under Section 608?

Any cylinder owner Any appliance wholesaler automatically An EPA-certified reclaimer Any Type I technician

Question 4

What is cylinder tare weight?

The maximum refrigerant mass for every gas The gross shipping weight when full The empty cylinder's weight The refrigerant's vapor pressure

Question 5

What is the safe response to a missing cylinder identification label?

Resolve identity before transfer or shipment Guess from odor Mix contents with a known refrigerant Apply any available refrigerant label

Question 6

What is a dry-nitrogen break used for in an approved multiple-evacuation procedure?

Create an oxygen-rich circuit Replace all recovery requirements Permanently raise refrigerant ODP Help dilute and remove residual moisture and gases

Question 7

Liquid saturation temperature is 100°F and actual liquid temperature is 88°F. What is subcooling?

88°F 188°F 100°F 12°F

Question 8

Which protection is appropriate for handling refrigerant connections?

Cotton gloves as the only required protection Unprotected eyes if pressure is low Suitable gloves and eye protection Ordinary sunglasses alone

Question 9

What is a limitation of using pressure decay alone?

It directly measures refrigerant composition Temperature changes and test conditions affect interpretation It distinguishes every thermal change from leakage automatically It pinpoints the leaking joint without another method

Question 10

For a zeotropic blend, which chart point is normally used to calculate liquid subcooling?

Critical point Dew point Bubble point Freezing point of water
