Job Safety Analysis:

Step / Description / Hazard / Controls
1 / Inspect work area. Ensure clean work area, check for any flammable or combustible materials. / Fire, Explosion. / Good Housekeeping, keep area clean, clear away debris. Ensure that flammable or combustible materials are moved away before starting work. Make sure surface is clean and dry.
2 / Check the power cord for any nicks or cuts. Make sure the cord is properly grounded. / Electrical short or shock may occur. / Make sure there are no cuts in the power cord. Make sure it is properly grounded and all three prongs are in good working order.
Do not use if cord is damaged. Report to instructor for tag out and repair.
3 / Use in areas with sufficient ventilation.
Do not allow refrigerants to come in contact with open flame. Refrigerant decomposition in flame results in phosgene gas. / Avoid dangerous environments.
Flammable, combustibility.
Breathing phosgene gas can be fatal. / Use in areas with sufficient ventilation.
Check surrounding areas for combustibles.
4 / Instructor must first visually inspect the tanks and project before recovering the gas. / Exposure of gas in the environment. Transfer of wrong gas causing major damage to the Yellow Jacket System. / Instructors to inspect the project before the students continue.
5 / Turn off power to the system being serviced. Turn the selector knob to the off position. / Electrocution / Make sure all power is off.
6 / Identify type and quantity of refrigerant to be recovered. Find label on the system. / Familiarize yourself to the system and refrigerant.
7 / Set up recovery tank on refrigerant scale on a level and stable surface. Record weight without hose attached. / Muscle strain
Crush hazard if dropped / Use proper lifting techniques.
Wear CSA approved safety shoes.
8 / Make sure the hoses for handling the refrigerant are 3/8”. The hoses should be the minimum length required for each job and equipped with a shut-off device (such as the compact ball valve). / Reduce the likelihood of refrigerant leaks to the atmosphere. / Check the hoses and the shut off valves before starting the process.
9 / Use caution when connecting or disconnecting the hoses. / Frostbite / Personal protective equipment should be worn to protect operator from frostbite.
10 / Connect your manifold to the system being serviced. High side to the liquid(red) port and low side to the vapor(blue). See manual. / Frostbite / Make sure the valves are in the closed position before connecting. Be sure to connect hose ends with shut-off to suction and discharge ports of recovery machine. (For best performance use 3/8” hoses).
11 / Connect the utility port of your manifold to the ¼” suction port of the Recover XL. See manual. / Frostbite / Make sure the valves are in the closed position before connecting. Be sure to connect hose ends with shut-off to suction and discharge ports of recovery machine. (For best performance use 3/8” hoses).
12 / Connect one hose from the recovery cylinder (liquid side) to the ¼” discharge port of the recovery XL. / Frostbite / Make sure the valves are in the closed position before connecting. Be sure to connect hose ends with shut-off to suction and discharge ports of recovery machine. (For best performance use 3/8” hoses).
13 / Double check connections, type of refrigerant before proceeding. Make sure recovery unit is switched OFF, and selector is in OFF position. / Refrigerant leaks
Improper refrigerant tank
Damage to Yellow Jacket unit / Make sure all connections are properly secured and refrigerant recovery tank matches type of refrigerant in system.
14 / Plug the recovery unit into a properly grounded receptacle using the appropriate plug. / Electrical short or shock may occur. / Check plug and receptacle before continuing.
15 / Open the liquid valve on the recovery tank. / Frostbite / Ensure the hose is attached securely.
16 / Turn the Recovery Unit on.
17 / Turn the selector VALVE on the Recovery Unit to LIQUID RECOVERY position.
18 / Open the High Side and Utility valves on your manifold and use them to regulate the refrigerant pressure to 80 psi maximum.
19 / The Recovery Unit will recover the liquid refrigerant. When you have removed all the liquid in the system switch to vapor recovery procedure step 9 to reduce your recovery time.

#21
Purge all hoses of non condensable before recovering refrigerant into recovery cylinder. / Frostbite
