Key Hazards
- Heat stress or cold stress during outdoor work
- Lightning, high winds, or severe storms
- Slips and falls from rain, mud, snow, or ice
- Reduced visibility from fog, rain, snow, dust, or darkness
- Unstable ground from wet or frozen conditions
- Delayed response to changing weather
2–3 Minute Talk Script
Weather exposure affects nearly every part of jobsite safety. Heat, cold, wind, rain, lightning, snow, ice, fog, and mud can change footing, visibility, equipment operation, communication, and worker condition.
Crews should check weather conditions before work begins and continue monitoring throughout the day. Conditions can change quickly, especially during storms, seasonal transitions, or long outdoor shifts.
Heat and cold exposure should be managed before workers become sick. Water, shade, warm-up areas, breaks, proper clothing, and adjusted work pace may be needed depending on the conditions.
Rain, snow, ice, and mud can make walking surfaces unstable. Workers should watch for slick ladders, wet equipment steps, muddy slopes, soft ground, and hidden holes or debris.
High winds can create hazards with ladders, lifts, cranes, materials, signs, temporary structures, and suspended loads. Loose materials should be secured before wind becomes a problem.
Lightning and severe weather require early action. Outdoor work should stop when conditions become unsafe, and workers should know where to shelter before the storm arrives.
Weather can also affect equipment and traffic safety. Poor visibility, longer stopping distances, soft ground, and reduced traction can increase the risk of struck-by incidents and vehicle loss of control.
Jobsite weather exposure should be treated as a changing condition, not background noise. The crew should be willing to pause, adjust, or stop work when weather changes the risk.
Safety Reminders
- Check weather before and during the job.
- Plan for heat, cold, rain, wind, lightning, and poor visibility.
- Adjust work pace and breaks for weather exposure.
- Secure loose materials before high winds.
- Watch for slick, muddy, frozen, or unstable surfaces.
- Know where shelter is located.
- Stop work when weather creates uncontrolled hazards.
Ask the Crew
- What weather conditions could affect the job today?
- Are workers prepared for heat, cold, rain, wind, or storms?
- Could footing, visibility, or equipment operation change during the day?
- Where will workers shelter if severe weather develops?
- Who will make the stop-work decision if conditions become unsafe?
