To implement winter weather safety precautions on a construction jobsite, consider the following measures:

1. Hazard Identification and Assessment: Identify potential hazards associated with extreme cold and winter weather that could lead to injury, illness, or incidents. Assess these hazards based on the probability and severity of potential harm to workers. [4]

2. Engineering Controls: Improve heating in work areas and provide heated shelters for rest and breaks. Ensure that tools and equipment can be safely operated while wearing gloves or other winter clothing. Maintain work vehicles and ensure they have snow tires and functioning heaters. [1]

3. Administrative Controls: Use weather surveillance procedures to identify upcoming cold events and detect the sudden onset of cold events. Have emergency plans and procedures in place to respond to extreme cold events. Train workers on how to identify health effects of cold stress, emergency procedures, pacing work to avoid overheating and cooling, and the proper use of winter weather clothing and PPE. [1]

4. Personal Protective Equipment (PPE): Provide workers with appropriate PPE and clothing for working in the cold, considering temperature, weather conditions, activity level and duration, and job design. Equip workers with emergency supplies and equipment, especially if they are offsite or traveling. [1]

5. Preventing Slips and Falls: Clear snow and ice from walking surfaces and spread deicer as quickly as possible after a winter storm. Train workers to wear footwear with good traction and insulation, take short steps, and walk at a slower pace. [2]

6. Preventing Falls from Elevated Surfaces: Consider options to avoid working on roofs or elevated heights. If work at height is unavoidable, provide required fall protection and training. Ensure ladders are used safely, clearing snow and ice from surfaces. [2]

7. Cold Stress Prevention: Schedule heavy work during warmer parts of the day and assign workers in pairs to monitor each other for signs of cold stress. [2]

8. Carbon Monoxide (CO) Prevention: When heating an enclosed space, use an indirect-fired heater. Check propane vehicle-cab heaters for leaks and proper venting. Operate engines outdoors when possible, and monitor CO levels regularly with a gas detector when engines must be operated indoors. [3]

9. Winter Driving Safety: Slow down, increase following distance, and be aware of black ice. Avoid using cruise control and steer with smooth movements. Keep a winter driving kit in vehicles. [7] [6]

10. Emergency Preparedness: Develop and implement a cold stress plan and an emergency response plan. [5]
