Hose/Line HVAC: Service Precautions

REFRIGERANT IN EYES OR ON SKIN

1.

If liquid refrigerant contacts the eyes, bathe eyes quickly in cool water and apply a non-irritating disinfectant oil.  Contact a physician immediately. 
Do not attempt self-treatment.

2.

If liquid refrigerant contacts the skin, do not rub.  Flush area with cool water and apply clean petroleum jelly.  Contact a physician immediately.  Do
not attempt self-treatment.

HANDLING REFRIGERANT (R-12 FREON)

1.

Shops performing A/C service must be equipped with approved refrigerant recycling equipment.  Technicians must be trained in proper handling of
R-12 and in the operation of recycling equipment.

2.

As either gas or liquid, Freon (R-12) is colorless and odorless.  It boils (vaporizes) at - 21.7°F.  Liquid refrigerant that may contact the skin will
momentarily be approximately 22°F below zero.

3.

Always wear eye protection.

4.

Do not handle refrigerant near an open flame.  Poisonous phosgene gas is produced when R-12 is burned.

5.

Keep refrigerant service and storage drums below 104°F (40°C).  Pressure caused by high temperatures may cause safety plugs to blow or drums to
burst.

6.

When connecting and disconnecting manifold gauges, ensure that both gauge valves and compressor service valves (if equipped) are closed.

7.

When purging system, discharge refrigerant slowly to minimize oil loss.

8.

When disconnecting or connecting refrigerant lines, use a back-up wrench and torque carefully. Over-tightening will result in line and flare seat
distortion and a system leak.

9.

After disconnecting gauge lines, check valve areas to be sure service valves are correctly seated and Schrader valves (if equipped) are not leaking.
