1. Winter driving

Although employers can’t control roadway conditions, they can promote safe driving behavior by ensuring that their workers:

• Recognize the hazards of winter weather driving, for example, driving on snow- or ice-covered roads;
• Are properly trained for driving in winter weather conditions; and
• Are licensed (as applicable) for the vehicles they operate.

Employers should set and enforce driver safety policies. Employers should also implement an effective maintenance program for all vehicles and mechanized equipment that workers are required to operate.

Employers should ensure properly trained workers inspect the vehicle systems, such as brakes, tires and the exhaust system, to determine whether they’re working properly, and make immediate repairs if they aren’t.

Workers who have to be out in winter weather, especially in storms, should all carry emergency kits that include the following:

• Cellphone or two-way radio.
• Windshield ice scraper, snow brush and shovel.
• Flashlight with extra batteries.
• Tow chain.
• Traction aids (bag of sand or cat litter).
• Emergency flares and a first-aid kit.
• Jumper cables.
• Snacks and water.
• Road maps.
• Blankets and a change of clothes.

2. Work zone traffic safety

Workers being struck by vehicles or mobile equipment lead to many work zone fatalities or injuries annually. Drivers may skid, or lose control of their vehicles more easily when driving on snowy or icy roads, or in a storm with significantly reduced visibility.

Employers must ensure that work zones are correctly set up with the traffic controls identified by signs, cones, barrels and barriers, to protect workers.

Workers exposed to vehicular traffic should wear the appropriate high visibility vest at all times, so that they can be easily seen by motorists.

3. Stranded in a vehicle

Employers should train employees on what to do if they’re stranded in a vehicle.

• Stay in the vehicle. Call for emergency assistance if needed, recognizing that response time may be slow in severe winter weather conditions.
• Notify your supervisor of your situation. Don’t leave the vehicle to search for assistance unless help is visible within 100 yards. You may become disoriented and get lost in blowing and drifting snow.
• Display a trouble sign by hanging a brightly colored cloth on the vehicle’s radio antenna and raising the hood.
• Turn on the vehicle’s engine for about 10 minutes each hour and run the heat to keep warm. Also, turn on the vehicle’s dome light when the vehicle is running as an additional signal. Beware of carbon monoxide poisoning. Keep the exhaust pipe clear of snow, and open a downwind window slightly for ventilation.
• Watch for signs of frostbite and hypothermia. Do minor exercises to maintain good blood circulation in your body. Clap your hands and move your arms and legs occasionally. Try not to stay in one position for too long. Stay awake, you will be less vulnerable to cold-related health problems. Use blankets, newspapers, maps and even the removable car mats for added insulation.
• Avoid overexertion since cold weather puts an added strain on the heart. Unaccustomed exercise such as shoveling snow or pushing a vehicle can bring on a heart attack or make other medical conditions worse.

4. Shoveling snow

Shoveling snow can be a strenuous activity, particularly because cold weather can be taxing on the body. There is a potential for exhaustion, dehydration, back injuries or heart attacks.

During snow removal in addition to following the tips for avoiding cold stress, such as taking frequent breaks in warm areas, there are other precautions workers can take to avoid injuries.

Workers should warm-up before the activity, scoop small amounts of snow at a time and where possible, push the snow instead of lifting it. The use of proper lifting technique is necessary to avoid back and other injuries when shoveling snow:

• Keep the back straight,
• Lift with the legs, and
• Don’t turn or twist the body.

5. Using snow removal equipment

It’s important to make sure that powered equipment, such as snow blowers, are properly grounded to protect workers from electric shocks or electrocutions. When performing maintenance or cleaning, make sure the equipment is properly guarded and is disconnected from power sources.

Snow blowers commonly cause lacerations or amputations when operators attempt to clear jams with the equipment turned on. Train workers to never attempt to clear a jam by hand.

• Turn the snow blower off and wait for all moving parts to stop.
• Use a long stick to clear wet snow or debris from the machine.
• Keep your hands and feet away from moving parts.

Workers should refuel a snow blower before starting the machine and never add fuel when the equipment is running or when the engine is hot.

6. Clearing snow from roofs and working at heights

Employers must evaluate snow removal tasks for hazards and plan how to do the work safely. Workers should be aware of the potential for unexpected hazards due to the weather conditions, for example, layers of ice can form as the temperature drops, making surfaces even more slippery. A surface that’s weighed down by snow must be inspected by a competent person to determine whether it’s structurally safe for workers to access it, because it may be at risk of collapsing.

Snow-covered rooftops can hide hazards such as skylights that workers can fall through. overhead power lines or snow removal equipment can also cause electrical hazards.

Employers can protect workers from these hazardous work conditions, for example, by using snow-removal methods that don’t involve workers going on roofs, when and where possible. Employers should determine the right type of equipment, such as ladders or aerial lifts, and personal protective equipment (PPE), such as personal fall arrest systems, for the job and ensure that workers are trained on how to properly use them.

7. Preventing slips on snow and ice

To prevent slips, trips and falls, employers should clear walking surfaces of snow and ice, and spread de-icer, as quickly as possible after a winter storm. In addition, the following precautions will help reduce the likelihood of injuries:

• Require employees to wear proper footwear when walking on snow or ice is unavoidable, because it is especially treacherous. A pair of insulated and water resistant boots with good rubber treads is a must for walking during or after a winter storm.
• Suggest that employees keep a pair of rubber over-shoes with good treads that fit over street shoes at the workplace during the winter months.
• Remind employees to take short steps and walk at a slower pace so they can react quickly to a change in traction, for example, when walking on an icy or snow-covered walkway.

8. Repairing downed or damaged power lines

A common problem during a blizzard or other winter storm can be a power outage. Repairing or replacing damaged power lines in severe winter weather conditions is especially hazardous to workers. The moisture in snow can reduce the insulation value of protective equipment and could cause electrocution. In these conditions de-energized work is safer, but if energized work must be done, qualified workers and supervisors must first conduct a hazard analysis that includes evaluating the weather conditions and identifying how to safely do the job.

Other potential hazards include:

• Electrocution by touching downed energized power lines or objects, such as broken tree limbs, in contact with downed energized power lines,
• Fires caused by an energized line or equipment failure, and
• Being struck or crushed by falling tree limbs or collapsing utility poles.

When working on downed or damaged power lines, electrical utility workers should use safe work practices, as well as appropriate tools and equipment (including PPE).

9. Working near downed or damaged power lines

As employees clear parking lots and sidewalks, or return to working on construction projects, for example, they might encounter downed power lines.

Employers should train workers to assume that all power lines are energized and stay clear of any that have been knocked down or damaged by winter weather, which could include a storm or icicles hanging from the lines.

When workers find downed or damaged power lines, they should establish a safe zone, some distance away from power lines and report any incidents to the responsible authority. Only properly trained electrical utility workers can handle damaged power lines.

10. Removing downed trees

Clearing downed trees is a critical job during severe winter weather conditions, and the job often falls to emergency crews to remove any trees that block public roads and damage power lines.

• Potential hazards include:
• Electrocution by contacting downed energized power lines or contacting broken tree limbs in contact with downed energized power lines,
• Falls from heights, or
• Being injured by equipment such as chain saws and wood chippers.

Workers should wear PPE that protects them from the hazards of the tree removal tasks. Workers using chainsaws and chippers to clear downed trees should use gloves, chaps, foot protection, eye protection, fall protection, hearing protection and head protection.

Ensure that equipment is always maintained in serviceable condition and inspected before use by a knowledgeable person who can identify any problems with the equipment. Don’t use equipment that is not functioning properly.

Equipment must have proper guarding; safe guards must never be bypassed. All controls and safety features must function as designed by the manufacturer.
