Cold Weather: Protect the Worker and the Walking Surface

Know the hazard

Team: General Small Business. Topic: Occupational Health.

Cold exposure is affected by wind, moisture, clothing, work demands, and time outside. Wet clothing and tired workers can lose protection quickly. Plan the work and warming opportunities before the crew arrives, including tasks that seem brief but repeat throughout the shift.

Use the controls

Wear suitable layers and keep clothing as dry as practical. Use the established warming plan, check on coworkers, and report numbness, loss of coordination, unusual confusion, or other concerning symptoms. Seek emergency help for suspected serious cold illness, and follow trained first-aid or dispatcher instructions. Do not assume someone is simply being clumsy or uncooperative.

Work within the safe plan

Inspect routes for ice, snow, hidden changes in level, and poor lighting. Treat or restrict unsafe surfaces and maintain a usable route to emergency exits. Snow removal creates its own exertion, equipment, and traffic hazards, so assign it with an appropriate plan. Do not operate combustion equipment indoors to warm an area. Today, we will identify who checks conditions after refreezing and how employees obtain dry clothing or a warm recovery location when conditions deteriorate.

Discuss with the crew

An evening crew arrives after melted snow refreezes across the employee entrance. Salt was applied early that morning.

Question: Does the earlier treatment establish a safe route now?
Answer guidance: No. Conditions changed; the current surface must be checked and controlled.

Question: What should happen before normal access resumes?
Answer guidance: Provide an effective treated or alternate route, restrict the hazardous area, and communicate the change.

Prepare, act, and follow up

Leader preparation: Identify warm shelter, weather information, and the site's ice treatment responsibility.

Put it into practice: Identify a weather-triggered inspection and a safe warming location for exposed work.

Supervisor follow-up: Assign reinspection after precipitation or temperature changes and review winter supply availability.
