Low GWP refrigerant practice Questions 100% Correct!

The minimum concentration of a refrigerant that can propagate a flame through a consistent mixture of the refrigerant and air is known as the: Acute toxicity exposure limit (ATELL). Immediately dangerous to life or health concentration (IDLH). Lower flmmability limit (LFL). Upper explosive limit (UEL). - ANSWERLower flmmability limit (LFL). The first stage of the evacuation process which removes non-condensables from a system is called: degassing. dehydration. recovery. Recycling. - ANSWERrecovery Once a flammable refrigerant has been recovered and stored in a cylinder: It can be taken a safe distance from the jobsite and vented to the atmosphere. It must be placed a safe distance away from the work area before a system repair or installation is started. It must be placed in ice to ensure it stays below the refrigerant's ignition temperature. It should be returned toa reclamation facility prior to beginning the installation of new equipment. - ANSWERIt must be placed a safe distance away from the work area before a system repair or installation is started.
