KLE/NFELOER (�H e a l t h& Safety Procedure HSP-5-09 Version 10 COLD STRESS Number: Number: Published 5/4/2018 Revised N/A Date: Date: • Assigning extra workers to highly demanding tasks; • Allowing workers to pace themselves, and take extra work breaks when needed; • Making relief workers available for workers who need breaks; • Teaching workers the basic principles of preventing cold stress and emergency response to cold stress; • Maintaining protective supervision or a buddy system for those who work at— 12°C (10°F) or below; • Allowing new employees time to adjust to conditions before they work full-time in cold environments; • Arranging work to minimize sitting still or standing for long periods of time; • Reorganizing work procedures so that as much of the job as possible is performed in a warm environment. This will reduce the amount of work that must be done in a cold environment; and • Including the weight and bulkiness of clothing when estimating work performance requirements and weights to be lifted. 5-09.6.2 Special Considerations Older workers or workers with circulatory problems need to be extra careful in the cold. Additional insulating clothing and reduced exposure time should be considered for these workers. Obese, extraordinarily thin, and chronically ill people need to make a special effort to follow preventive measures. Sufficient sleep and good nutrition are important for maintaining a high level of tolerance to cold. If possible, the most stressful tasks should be performed during the warmer parts of the day. Double shifts and overtime should be avoided. Rest periods should be extended to cope with increases in cold stress. A worker should immediately go to warm shelter if any of the following symptoms are spotted: the onset of heavy shivering, frostbite, the feeling of excessive fatigue, drowsiness, and/or euphoria. The outer layer of clothing should be removed when entering a heated shelter. If possible, a change of dry work clothing should be provided to prevent workers from returning to work with wet clothing. If this is not feasible, the remaining clothing should be loosened to permit sweat to evaporate. Alcohol should not be consumed while in the warmer environment. Anyone on medications such as blood pressure control or water pills should consult a physician about possible side effects from cold stress. It is strongly recommended that workers suffering from diseases or taking medication that interferes with normal body temperature regulation, or that reduces tolerance of cold, not be permitted to work in temperatures of-10C (30°F) or below.
