refrigeration installation in Jefferson CountyAmerican Services refrigeration repair service in MO,  as well as technicians  working  daily with refrigerant systems, know full well the potential hazards the refrigerants pose while installing, maintaining, and servicing the systems.  All of these operations, when  mishandled can lead to serious injury. Today’s classification system which includes toxicity rating, based on exposure of the individual during his working life without incurring ill effects.  Refrigerants in the A  class have no toxicity at concentrations at or below 400 ppm. The 1 represents flammability characteristics with the parameters being tested in there at 14.7, and 65, degrees Fahrenheit. Not all refrigerants in use today carry the safety classifications mentioned above.  This is a safety factor a technician should keep in mind when operating, with refrigerants outside the a 1 rating. Even below 20 degrees below 0, evaporation can happen, safety hazards, can still occur if abused, or handled roughly. Make sure all gaskets belonging to refrigerant hoses and other related equipment are maintained in good working order. If not split hoses can occur causing liquid refrigerant spray out, possibly resulting in severe frostbite. Technicians also need to use extreme caution with the schrader valve. Purchasing hoses with low lost fittings or adapters can reduce this hazard. Overall refrigerants are considered in the non toxic classification, however when operating in an enclosed area be careful not to inhale vapors or use a safety mask. Some symptoms of inhaling vapors include; dizziness, unconsciousness, nausea, irregular heartbeat, and even death which could occur if inhaled long enough. When refrigerants are exposed to heat and high temperatures, decomposed toxic and irritating byproducts are formed. Some of these toxic byproducts are hydrogen chloride hydrogen fluoride for c f c and h.  F c, and CFC, HCFC, HFC.

These vapors are acidic and extremely dangerous, all people should  evacuate the area and ventilate as soon as possible if vapors are released. Removal of any remaining refrigerant, prior to soldering or brazing will prevent this problem.

Another hazard is unsafe handling of cylinders.  Here are some safety handling features; never store cylinders above 130 degrees Fahrenheit, never use the torch on a refrigerant cylinder, never use a cylinder that is rusty or shows a bulge, relief valves should not be tampered with and recovery tanks tested every 5 years. Do not fill cylinders more than 80 percent capacity.

Following these safety steps will reduce injuries caused by refrigerant operation.
