Appendix L
Maintenance Level Guidelines
Whole Body and Skin Provisions for additional total body protection are required if work is done in an environment at or below 40 degrees Fahrenheit. At air temperatures of 35 degrees Fahrenheit or less, it is imperative that workers who become immersed in water or whose clothing becomes wet be immediately provided a change of clothing and be treated for hypothermia. The workers should wear cold protective clothing appropriate for the level of cold and physical activity as follows: 1. If the wind speed at the job site is increased by a draft, the cooling effect of the wind should be reduced by shielding the work area or by wearing a removable windbreak garment. 2. If only light work is involved and if the clothing on the worker may become wet on the job site, the outer layer of the clothing in use should be of a type impermeable to water. With more severe work under such conditions, the outer layer should be water repellant, and the outerwear should be changed if it becomes wet. If clothing is wet, the employee should change into dry clothes before re-entering the cold area. 3. If the available clothing does not give adequate protection to prevent hypothermia or frostbite, work should be modified or suspended until adequate clothing is made available or until weather conditions improve. 4. Workers handling evaporative liquid (gasoline, alcohol or cleaning fluids) at air temperatures below 40 degrees Fahrenheit should take special precautions to avoid soaking of clothing or gloves with the liquids because of the added danger of cold injury due to evaporative cooling. Warming Regimen If work is done continuously in the cold at or below 20 degrees Fahrenheit, the following issues should be considered: 1. Heated warming shelters (trucks, rest rooms, warming shelters, etc.) should be made available nearby and should be used with Table 2. The workers should use these shelters at regular intervals, depending on the severity of the environmental exposure. 2. Workers should work in dry clothing, if none is available, work should stop until clothing dries. When entering the heated shelter, the outer layer of clothing should be removed and the remainder of the clothing loosened to permit sweat evaporation or a change of dry work clothing provided. 3. Dehydration, or the loss of body fluids, occurs deceptively in the cold environment and may increase the susceptibility of the worker to cold injury due to a significant change in blood flow to the extremities. Warm sweet drinks and soups should be eaten to provide caloric intake and fluid volume. The intake of coffee should be limited because of the diuretic and circulatory effects.
