Clothing, shelter and site measures for heat, cold, rain, snow, wind and smoke.
Tap your level and the boxes below open to the advice for you. Remembered on this device.
By the end you can
- Dress in layers for cold and wet.
- Set up a hot-weather routine.
- Tell heat exhaustion from heat stroke and act.
- Protect the work from the weather and plan around the forecast.
Heat stroke and cold stress are emergencies. Confusion, collapse, seizures or hot red or dry skin means heat stroke: call 911 and cool the person now. Stop work when the weather makes it unsafe, and do not run an unvented fuel burner in a closed space.
The big idea
Weather decides how fast you work, how well concrete cures and whether people get hurt. The building code does not set worker heat and cold rules; provincial OHS rules do. Concrete in hot and cold weather is covered by the code and CSA A23.1 (see Hot and Cold Weather Adjustments). Employers are expected to protect workers from heat and cold. Confirm the sections and any temperature triggers with your regulator.
Hot weather
- Water within reach, and drink regularly before you are thirsty.
- Shade or a cool place to rest, and extra breaks as the heat builds.
- Light, breathable, hi-vis clothing, a brimmed hard hat or sun shade, UV-rated glasses and sunscreen.
- Fans and misting where you can. Give new or returning workers time to adjust.
| Condition | Signs | Act |
|---|---|---|
| Heat exhaustion | Heavy sweating, pale clammy skin, dizziness, weakness, nausea, headache, fast pulse, possible fainting | Stop work, shade, lie down, remove excess clothing, cool the skin, sip cool water, stay with them |
| Heat stroke | Confusion or agitation, collapse, hot red or dry skin, seizures | Call 911 immediately and cool rapidly |
Call 911 for heat exhaustion too if they vomit, become confused, faint or get worse. Send for medical evaluation if symptoms last more than 30 to 60 minutes despite treatment, and no return to work that day.
Signs and steps from a BC construction association factsheet (RCABC), which cites OSHA and CDC. It cites no WorkSafeBC sections, so confirm your regulator's guidance.
Cold weather
- Three layers: a close-fitting wicking base, a warm mid layer, and a wind- and water-resistant shell that fits over them without being tight.
- Dry spares: socks, gloves, hat and base layer. Damp clothing can rapidly drop your core temperature.
- Insulated gloves that still let you work, insulated safety boots, and a hard-hat liner made for your hat.
- Breaks: a work and rest schedule with a place to warm up. How often depends on air temperature, wind and humidity, and some provinces point to published exposure limits (PEI cites the ACGIH TLVs). Confirm yours.
- If someone shows signs of cold stress, get them warm and call for help. Learn the signs from your regulator's cold stress guidance.
Wet, snow, wind and smoke
- Wet: waterproof hi-vis jacket and pants, waterproof slip-resistant boots and gloves, dry spares, tarps and shelters for the work and the materials. Extra care with GFCI tools, ladders and slippery planks.
- Snow and ice: traction cleats, sanded or salted walkways, ladders and platforms, and check that snow does not hide holes, rebar or open excavations.
- Wind: windproof jackets, sealed eye protection, weighted tarps, extra bracing for forms, scaffold and fences. Stop work with cranes, pump booms, tall forms and ladders when wind passes the maker's or the site's limit.
- Smoke: respirators or masks and a plan for smoke days. Confirm your regulator's rules.
Seasonal tool and site adjustments
- Cold-weather fuel and oil, and warm storage for batteries.
- Heated hoses and protected water lines in freezing weather.
- Shade, heater and windbreak setups; snow and ice clearing; mud control and drainage so water does not pool.
- Concrete admixtures only as the supplier and engineer allow.
- Check the forecast every day and plan the pour for the weather.
Example (numbers made up). 8 workers each drinking 250 mL every 20 minutes over a 6-hour shift: 6 × 3 = 18 servings × 250 mL = 4.5 L each, so 8 × 4.5 = 36 L for the crew. Bring more on hot days.
Common mistakes
- Gear that does not match the season
- No water in the heat
- No frost protection for concrete
- No traction on snow and ice
- No windbreaks
- No protection for the work in rain
- Working in smoke without a plan
Weather affects curing, soil, comfort and safety all at once. Check the forecast, plan for it and adjust. The job does not stop, but you choose when to do each part.
Extreme heat, cold, storms and smoke are becoming more common. Have a plan before the day arrives and stop work when the risk is too high.
Heat and cold plans, drinking water, shelter, PPE for the conditions, and protection of the work. Confirm what your regulator checks.

Heat and cold stress rules are set by each province's and territory's OHS regulator, and the sections and temperature triggers differ. WHMIS and the CSA PPE standards are national. I could not verify per-province sections here, so none are listed. Confirm with your regulator and workers' compensation board.
