A Casper technician completes a repair on a system containing more than 50 pounds of refrigerant. What record-keeping is required under EPA Section 608?

Answer: Lower toxicity and no flame propagation
ASHRAE's 'A' designation means lower toxicity and '1' means no flame propagation was observed during testing.
Which condition would require a technician to perform an immediate equipment shutdown and evacuation of an occupied space?
Answer: Detection of refrigerant concentration above the ASHRAE 34 ATEL or room concentration limit
When refrigerant concentration reaches or exceeds ASHRAE 34's Acute Toxicity Exposure Limit (ATEL) or room concentration limit, immediate evacuation is required to protect occupants.
