Work Environment

Heating, air conditioning, and refrigeration mechanics and installers work in homes, retail establishments, hospitals, office buildings, and factories-anywhere there is climate-control equipment that needs to be installed, repaired, or serviced. Technicians may work outside in cold or hot weather, or in buildings that are uncomfortable because the air conditioning or heating equipment is broken. In addition, technicians might work in awkward or cramped positions, and sometimes they are required to work in high places. Hazards include electrical shock, burns, muscle strains, and other injuries from handling heavy equipment. Appropriate safety equipment is necessary when handling refrigerants because contact can cause skin damage, frostbite, or blindness. When working in tight spaces, inhalation of refrigerant is a possible hazard.
