Working With Scaffolding in Winter

Winter may slow construction down, but it doesn’t stop it, and when scaffolding is involved, cold-season hazards require a higher level of attention. Ice, snow, freezing temperatures, and strong winds can turn a standard setup into a serious safety risk. Whether you’re a contractor, site supervisor, or equipment manager, understanding how winter weather affects scaffolding safety is essential to keep your crew protected and your project moving forward.

Below is an updated, winter-focused guide on how weather impacts scaffold stability and what precautions you should take before anyone steps onto a platform.

How Winter Weather Affects Scaffolding Safety and Stability

1. Ice on Platforms and Access Points

Ice buildup is the biggest cold-weather threat. Even thin layers create slip hazards that can send a worker off balance.

• Ice adds weight to the scaffold structure.

• Ladders, planks, and guardrails can become dangerously slick.

• Freezing rain can coat couplers and locking mechanisms, causing improper engagement.

2. Snow Load Stress

Heavy snow accumulation can stress scaffold frames and platforms well beyond intended load capacity.

• Wet snow is significantly heavier than dry snow.

• Accumulated snow between planks can hide hazards or cause planks to shift.

3. High Winds and Cold Fronts

Winter winds hit harder, especially on elevated platforms.

• Wind chill affects a worker's grip, stamina, and reaction time.

• Gusts make sheeting, or tarps, act like sails if not secured correctly.

• Sudden weather changes can turn a stable setup unstable in minutes.

4. Frozen Soil and Foundation Issues

Cold ground may seem solid, but frost heave can cause:

• Shifts in base plates or leveling jacks

• Uneven settling

• Misalignment of vertical frames

Even a slight shift compromises scaffold integrity.

Precautions to Take During Winter Weather

1. Conduct Frequent Inspections

In winter, inspections shouldn’t be a once-a-day task.

• Check platforms first thing in the morning for ice and snow.

• Re-inspect after lunchtime when temperatures shift.

• Look closely at all locking devices—ice can prevent full lock-in.

2. Remove Ice and Snow Properly

Use the right clearing techniques:

• Use plastic tools to prevent damage to planks or metal components.

• Never use salt—it corrodes scaffolding.

• Heated mats or de-icing chemicals approved for metal may be used on surrounding walkways, but not on the scaffold itself.

3. Secure Windbreaks and Tarps

If you’re enclosing scaffold:

• Tie off sheeting at every point recommended by the manufacturer.

• Avoid overloading the structure with overly heavy plastic or canvas.

• Inspect tie-downs after storms or overnight temperature changes.

4. Monitor Weather Constantly

Winter weather shifts fast.

• Wind forecasts should be checked daily.

• Delay work if freezing rain or heavy snow is on the way.

• Document conditions to protect workers and your company.

5. Protect the Base

A stable scaffold starts at the ground.

• Lay down mudsills or base plates on non-frozen stable ground.

• Avoid building directly on snowpack—thawing will cause shifting.

• Re-level often as temperatures rise during the day.

6. Keep Workers Warm and Alert

Cold stress is a major safety issue.

• Encourage proper PPE: insulated gloves with good grip, layered clothing, and windproof PPE.

• Implement warm-up breaks.

• Limit time spent at height during extreme cold or wind chills.

7. Train Crews on Winter Hazards

Winter conditions change the rules.

• Refresh training on slip prevention, load limits, and hazard identification.

• Ensure workers understand how ice and wind change the behavior of scaffolding systems.

A well-trained crew becomes your best winter safety tool.

Winter doesn’t have to halt progress, but it does require a more disciplined approach. A safe scaffold is a combination of correct setup, constant monitoring, and trained workers who understand how weather transforms the jobsite.

Southwest Scaffolding provides high-quality scaffolding and access solutions built to perform safely all year long. If your crews are working through the winter months, now is the perfect time to review your procedures, upgrade equipment, and make sure every scaffold on your site is winter-ready.
