Weather Conditions and Fall Hazards
The Problem
Weather conditions can significantly increase the risk of falls on the job site. Wet surfaces, icy scaffolding, or strong winds can turn even routine tasks into dangerous situations. Falls remain one of the leading causes of workplace fatalities in Canada, and weather-related hazards only increase this risk. Today, we’ll discuss how weather impacts fall hazards and what we can do to stay safe.
Identify the Hazards
- Slippery Surfaces: Rain, frost, or ice can make walking or working surfaces slick, increasing the risk of slips and falls.
- Reduced Visibility: Fog, heavy rain, or snow can obscure hazards and make it harder for workers to move safely.
- Strong Winds: Wind can destabilize workers, tools, or materials—especially when working at heights or on scaffolds.
- Structural Weakness: Snow or ice buildup can place additional stress on scaffolds, roofs, and platforms, increasing the risk of collapse.
Safety Practices and Preventative Measures
Pre-Work Inspection
- Inspect all walking and working surfaces for ice, frost, or water before starting work.
- Check ladders, scaffolds, harnesses, and anchorage points to ensure they are secure and safe.
Safe Work Practices
- Wear slip-resistant footwear suitable for the site conditions.
- Use compliant edge protection, harnesses, and fall arrest systems.
- Do not work on unstable or visibly hazardous surfaces caused by weather conditions.
Weather Monitoring
- Monitor local weather forecasts and site conditions throughout the day.
- Stop work immediately if weather becomes unsafe (e.g., high winds, heavy rain, snow, or electrical storms).
Clean and Maintain Surfaces
- Remove snow, ice, and debris from work areas before beginning tasks.
- Use grit, salt, or non-slip mats on walkways and access points.
Communication and Training
- Discuss weather-related hazards during pre-start meetings.
- Ensure workers are trained to identify weather-related risks and understand the proper use of fall protection systems.
Real-Life Case or Scenario
For example, in a recent incident, a worker slipped on an icy scaffold platform and fell nearly 4.5 metres. The platform had not been inspected or cleared before work began, and no fall arrest equipment was in use. The worker sustained serious injuries. This incident highlights why thorough pre-work inspections and proper use of PPE are essential—especially in poor weather conditions.
Employee Responsibilities
Employer Responsibilities
- Provide compliant fall protection systems, including harnesses, scaffolds, and guardrails.
- Ensure all work surfaces are cleared and treated (e.g., snow, ice, or water removed) before work begins.
- Train workers to recognize and manage weather-related fall hazards as part of their fall protection training.
- Monitor weather conditions regularly, and pause or postpone work if conditions become unsafe.
Discussion & Questions
- “What types of weather conditions have you encountered that made work unsafe?”
- “How do you check your work area for fall hazards related to weather?”
Encourage workers to share past incidents or raise concerns related to weather conditions.
Commitment/Action Plan
Let’s commit to inspecting all work areas for weather-related risks before starting each day. If you spot a hazard, stop and report it immediately. By working together, we can reduce the risk of weather-related falls and help keep everyone safe.
Wrap-Up
Weather conditions can change quickly and create serious fall hazards. By staying aware, using fall protection, and supporting one another, we can prevent injuries and protect lives. Thank you for prioritizing safety and looking out for your workmates.
Standards Overview
Under Canadian occupational health and safety legislation and CCOHS guidance:
- Employers must identify and manage fall-from-height risks, including those caused or worsened by weather conditions.
- Fall protection systems and hazard identification procedures are required as part of a workplace's fall prevention program.
- Walking and working surfaces must be kept safe, even during adverse weather such as rain, snow, or high winds.
