Safety • Reduction of cold stress through engineering and administrative controls, and the use of PPE. 5-09.6.1 Control Measures Continuous exposure of skin should not be permitted when the Wind-chill factor results in an equivalent temperature of-320C (-260F). Workers exposed to air temperatures of 20C (35.6°F) or lower who become immersed in water or whose clothing gets wet should be given dry clothing immediately and treated for hypothermia. 5-09.6.1.1 Engineering Controls The following are some of the ways engineering controls can be used to reduce the stress of a cold environment: • General or spot heating should be used to increase temperature at the workplace. • If fine work is to be performed with bare hands for 10 or 20 minutes or more, special provisions should be made to keep the worker's hands warm. Warm air jets, radiant heaters, or contact warm plates can be used. • The work area should be shielded if the air velocity at the job site is increased by wind, draft, or ventilating equipment. • At temperatures below-1°C (300F), metal handles of tools and control bars should be covered with thermal insulating material. • Unprotected metal chair seats should not be used. • When necessary, equipment and processes should be substituted, isolated, relocated, or redesigned to reduce cold stress at the work-site. • Power tools, hoists, cranes or lifting aids should be used to reduce the metabolic workload. • Heated warming shelters, such as tents and cabins should be made available if work is performed continuously in an equivalent chill temperature of-70C (20°F) or below. Workers should be encouraged to use the shelters regularly. 5-09.6.1.2 Administrative Work Practice Controls • A work-rest schedule to reduce cold stress; • Enforcing scheduled rest breaks; • Enforcing frequent intake of warm, sweet, caffeine-free, non-alcoholic drinks or soup; • Scheduling the coldest work for the warmest part of the day; • Moving work to warmer areas whenever possible; Page b of 11 Copyright 2019 Kleinfelder, Inc Important: When modifying this document, update properties with your name, date, and nature of changes made.
