WORKING CONDITIONS: Shop conditions encountered at this level are the same as the WG-08 level, however, they differ in the requirement to
occasionally work outside on top of tall buildings, in drafty attic spaces, and in areas with low overhead clearance. Face masks and protective clothing may be worn to reduce the possibility of exposure to toxic refrigerants or other conditions. Refrigerants are used in larger quantities at this level due to the larger size of the systems which increases the amount of exposure when making repairs.

PHYSICAL EFFORT: The physical effort at this level is greater than that of the WG-08 level due to the larger size of the equipment that requires dismantling and reassembling to fit into their location. Carrying parts and equipment weighing up to 50 pounds is frequently required. Hoists, holders, and pulleys are utilized when removing large units. Ladders, scaffolding, and platforms are utilized to reach high up or hard to reach areas where equipment is located. Stooping, stretching, bending, and kneeling is required for long period of time to carry out the regular and recurring work.
