AECOM 4.5.9 Operation of internal combustion or similar devices within warming shelters is prohibited. 4.5.10 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. 4.5.11 Walking and working surfaces shall be cleared of ice and snow to prevent slips and falls. 4.5.12 Confirm that employees carry fire starter materials if working in remote areas. 4.5.13 Supplies such as PPE,fuels, enclosures, de-icing,traction aids, warm drinks, and batteries will be specified by the SH&E Manager and/or the Manager and made available.These supplies will be inspected at least weekly during cold weather projects and replaced when necessary. 4.6 Cold Stress Prevention Measures for the Hands 4.6.1 Special protection of the hands is required to maintain manual dexterity for the prevention of accidents including, but not limited to the following: • If fine work is to be performed with bare hands for more than 10 to 20 minutes in an environment below 60°F (15°C), special provisions should be established for keeping the employees' hands warm. For this purpose, warm air jets, radiant heaters(fuel burner or electric radiator), or contact warm plates may be utilized. Metal handles of tools and control bars should be covered by thermal insulating material at temperatures below 30°F(-1°C). • If the air temperature falls below 60°F (15°C)for sedentary work,40°F(4.4°C)for light work, or 20°F (-6°C)for moderate work, and fine manual dexterity is not required, employees should use gloves. 4.6.2 To prevent contact frostbite, employees should wear anti-contact gloves: • When cold surfaces below 20°F(-6°C)are within reach, each employee should be warned to prevent inadvertent contact by bare skin. • If the air temperature is 0°F (-18°C)or less, employees should protect their hands with mittens or appropriate gloves. Machine controls and tools for use in cold conditions should be designed so that they can be handled without removing the mittens or gloves. • Ensure an adequate supply of dry gloves is available to replace wet gloves. 4.6.3 Provisions for additional total body protection are required if work is performed in an environment at or below 40°F (4.40C).The employees should wear cold protective clothing appropriate for the level of cold and physical activity. 4.6.4 Additional Cold Stress Prevention Measures: For work practices at or below 10°F (-12°C) ECT,the following will apply: • The employee should be under constant protective observation (buddy system or supervision). • The work rate should not be so high as to cause heavy sweating that will result in wet clothing. If heavy work is being performed, rest periods should be taken in heated shelters and opportunities to change into dry clothing should be provided. • New employees should not be required to work full time in the cold during the first days of employment until they become acclimated to the working conditions and required protective clothing. Refer to S3AM-112-ATT1 Temperature Thresholds for guidance. • The weight and bulkiness of clothing should be included in estimating the required work performance and weights to be lifted by the employee. • The work should be arranged in such a way that sitting still or standing still for long periods is minimized. Unprotected metal chair seats should not be used. The employee should be protected from drafts to the greatest extent possible.
