Key Hazards
- Lightning, severe storms, or sudden weather changes
- High winds affecting ladders, lifts, materials, and equipment
- Rain, mud, snow, or ice changing walking and driving surfaces
- Heat stress or cold stress during outdoor work

- Workers continuing tasks after weather makes conditions unsafe
2–3 Minute Talk Script
Outdoor work can change quickly when the weather changes. A task that starts safely can become unsafe because of wind, lightning, rain, heat, cold, fog, or ground conditions.
Workers should review the forecast before outdoor work begins and continue watching conditions during the shift.
Lightning and severe storms require early action. Crews should know where to shelter and when work must stop.
Wind can affect ladders, aerial lifts, cranes, signs, tarps, panels, traffic control devices, and unsecured materials.
Rain, snow, ice, and mud can create slip hazards, vehicle control problems, unstable shoulders, and poor access to the work area.
Heat and cold exposure should be managed with water, breaks, shade, warm clothing, dry clothing, and task pacing as conditions require.
Reduced visibility can make traffic control, equipment operation, and pedestrian movement more dangerous.
Safe weather monitoring depends on checking conditions, recognizing changes early, communicating with the crew, and stopping or adjusting work before the weather creates an emergency.
Safety Reminders
- Check the forecast before outdoor work.
- Monitor weather throughout the shift.
- Stop work for lightning or severe weather when required.
- Secure materials before wind increases.
- Control slippery surfaces from rain, snow, ice, or mud.
- Adjust work for heat or cold exposure.
- Communicate weather changes to the crew.
Ask the Crew
- What weather hazards are possible today?
- Where will workers shelter if lightning or severe weather develops?
- Could wind affect materials, lifts, ladders, or traffic control?
- Are walking and driving surfaces changing?
- At what point should work pause or be rescheduled?
