When winter arrives, it's easy to think that having a roof fall protection system — like safety guard rails — isn’t a top priority. After all, outdoor work slows significantly in the colder months. The truth is, there’s plenty of reasons your workers may need to get out on the roof this winter, and you’ll want to play safe — no matter what the weather may bring.
Changing weather conditions can affect roof areas in unpredictable ways. Severe storms may dump several inches (and pounds) of heavy snow, frozen dams can pond water, and high winds can strip away exterior layers. There’s a good chance your employees or contractors will need to visit the roof after a heavy storm to assess the damage. Since snow can easily disguise hidden dangers like icy patches, debris, and skylights, having a game plan can really save the day.
Before we get started, here’s a quick look at the hazards winter brings to your rooftop.
While autumn is the ideal time to get your roof ready for winter, you still have time to get out there before the heavy-hitting storms come to pass. Here are six things to think about:
To ensure your roof remains OSHA compliant, have it inspected at least once a year, ideally, twice, to stay on top of any maintenance issues that could be exacerbated by inclement weather. If a severe winter storm hits, you should also have trained staff or professionals to inspect the area for damage.
During the inspection, your contractors should:
Next, you'll need to have all rooftop equipment inspected to make sure it's working properly.
Schedule a maintenance check for your Heating, Ventilation, and Air Conditioning (HVAC) equipment. HVAC can create roofing problems when its liquid leaks onto your roof. This equipment needs protection since it has sharp panels that can damage your roof's membrane.
During the maintenance check, your contractor should:
Have your roof fall protection system checked for any damage or problems. Make sure that your rooftop safety railing is in good, working order. OSHA asks employers to use systems that prevent falls over edges of buildings. See CFR 1926.501(b)(2). These include:
Trash, leaves, and other debris can block scuppers and drains. The water can pond, creating additional weight on your roof. All of this can be compounded by the presence of ice and snow. Get a professional on your roof to clean it up ahead of time and save yourself a headache down the road.
According to OSHA Standard 1926.501(a)(2), "employers shall determine if the walking/working surfaces on which its employees are to work have the strength and structural integrity to support employees safely." Before snow hits, eliminate all hazards from the roof area and use flags to mark any hazards that snow can hide. Flagging dangers will make roof-related work safer for your employees. When snowstorms hit, remove snow from walkways, curbs, and skylights to prevent employees from tripping over them.
Companies should tell workers about potential hazards caused by snow before they consider setting foot out on the roof. Make sure that your employees receive the required OSHA training about roof area hazards as well as how to use your roof fall protection system correctly.
This tip really is relevant year-round, but it’s worth the reminder. Your company can stay OSHA-compliant by keeping an updated roofing file. It should have the following information:
Hopefully, you’ll never have to use it. But having an action plan in place saves critical minutes if a fall does occur.
According to OSHA, employers must identify potential snow removal tasks on rooftop areas. To remain compliant, it’s in your best interest to have a snow-removal plan in place. Since snow makes rooftop work more precarious, your plan should include these OSHA tips.
High winds and icy surfaces are an obvious mix for a slippery situation. To protect your workers, you should:
According to OSHA standards, employers must identify each winter-related hazard workers can face on elevated construction sites of 6 feet or more (1926.501). The same requirements apply to non-construction sites 4 feet or higher.
If you choose to use a ladder or aerial lift, keep in mind they come with their own set of safety issues. OSHA advises workers not to use a shovel or snow rake while on a ladder. Using these tools can cause people to lose their balance and fall. Make sure the ladder has secure footing, check all rungs for ice and snow, and clean all snow from shoes or boots before climbing the ladder.
Aerial lifts are a great way to carry snow rakes, shovels, and other de-icing equipment. Remember, OSHA standards 1910.67(c)(ii) and 1926.454 require employers to train all workers to use lifts before they start using them. Workers should also operate snow removal equipment at reduced speeds in slippery conditions.
Even though a heavy dose of snow can cause a lot of headaches, having a plan in place makes it a lot easier for everyone involved. Taking precautions ahead of the storm can be even more helpful. Keeping rooftops free from debris and having a roof guardrail installed is a great start. If you need some extra help keeping your roof safe for the season, feel free to give a us call.
