Winter is in full swing, and in many areas of the country, the cold weather is having an adverse effect on driving conditions. The United States Department of Transportation’s Federal Highway Administration states that annually, an average of 22 percent of vehicle accidents are related to the weather. This amounts to almost 1.3 million accidents each year.
Snow, ice, and the impacts low temperatures can have on a vehicle make winter driving especially hazardous. Even regions typically associated with warm weather are not immune to the occasional, out-of-the-ordinary freeze. Whether you drive for work, to work, or just on errands, following these tips can save your life.
Prepare Your Vehicle
Much of safety is a matter of being proactive. While regular vehicle maintenance is crucial year round, it’s especially prudent during the winter when roads are icy. System and/or component failures increase safety risks dramatically. Long-haul drivers need to take special care inspecting their vehicles before beginning a trip; becoming stranded in the middle of nowhere in below-freezing temperatures is incredibly dangerous.
Remove all snow and ice from essential areas of your car. Clean the headlights, windows, mirrors, wheel wells, and forward and rear sensors. Where snow is concerned, clear off the hood and the top of the vehicle as well. Snow from your hood can blow up over your windshield and obstruct vision, and snow from the top of your car can blow back and do the same to drivers behind you.
Check your tires. It’s a good idea to have a spare set of winter tires on hand. Inspect the tread, and be sure the tires are inflated properly. Fluctuations in temperature can cause tires to expand and contract, ultimately leading to a loss of air pressure. Your state may have laws in place regarding the use of tire chains, including permitted timeframes and recommendations. A good set of winter-specific tires can be just as (if not more) effective as chains, but having a set of chains in the trunk can help with traction if you get stuck in the snow.
Inspect systems and fluid levels. Check the lights, exhaust system, heat and defrosting systems, brakes, and antifreeze. It’s a good idea to use a 50/50 mix of antifreeze and water to prevent freezing. Be sure your oil changes are on schedule – it can’t hurt to get it changed early if winter sets in before the next one is scheduled. Test your battery, and replace it if it’s more than 3 years old. Replace your windshield wipers if necessary; between snow and road salt, your windshield may get dirty several times in one short trip. The fuller you keep your gas tank, the better to prevent frozen gas lines in low temperatures.
Warming Your Car: If you don’t have a modern, fuel-injected car and need to idle it for a short time before driving it in the cold, do not do it in an enclosed space such as a garage. Carbon monoxide can build up quickly and lead to poisoning. In fact, you should avoid leaving your car running in any attached garage, even if the door is open, as the carbon monoxide can still find its way into your home.
Check the weather! So much hassle can be prevented by simply knowing what to expect ahead of a time. Always keep an eye on the weather forecast the night before, and plan accordingly.
Consider alternatives. In the case of extreme weather conditions, such as incredibly low temperatures and snow storms, you might be better off avoiding driving altogether. If it’s just a commute to work or an errand, taking advantage of public transit or other rideshare services which minimize the number of drivers on the road can be a safer bet.
Always be ready for an emergency. Even if your vehicle is in top condition, there is always the possibility of a breakdown. You can be the safest driver around, and another driver’s unsafe habits can still put you at risk of a collision. Being stranded in cold weather can go from annoying to life-threatening very quickly so being prepared is non-negotiable. Always keep your vehicle stocked with jumper cables (portable jump starters are preferable, if possible), a snow brush and ice scraper, flares or emergency lights, sand or kitty litter, blankets, a flashlight, a first aid kit, and a cell phone. If you’re expecting a long trip through rural areas where help may take a long time to arrive, include food and water.
If you do break down, especially in extremely low temperatures, it’s best to stay in your car while you wait for assistance. You can run the car heater for 10 minutes per hour, but check the exhaust pipe to ensure it’s free of snow or other obstructions to avoid carbon monoxide poisoning. Even during the 10 minutes of heating, you should crack your window to prevent buildup.
Drive with Safety in Mind
Keep in mind that speed limits are meant for ideal driving conditions, which do not include snow and ice. Adjust your speed and following distance for current conditions and visibility.
When roads are slippery, it may take more time and distance to come to a stop. Brake earlier than you normally would. This goes double for larger vehicles, which are heavier and require a greater stopping distance than smaller cars. Additionally, be wary of becoming overconfident in a 4×4’s capabilities, as they still require sufficient time and distance to come to a safe stop.
Watch out for bridges! Because they are open underneath, they’re quicker to freeze. Bridges are often the first areas of roadway to become covered by ice or black ice (ice which does not appear shiny and is essentially camouflaged by the black asphalt).
In snow and below-freezing temperatures, avoid using cruise control. The road may look clear, but can become slippery unexpectedly.
If your car slides, don’t slam on the brakes. This can cause you to quickly lose control. Instead, let go of the brakes and turn your wheel in the opposite direction in which your front end is moving. Do not panic or overreact, which will make the spin worse.
When driving up a snowy hill, get some inertia going ahead of a time – enough to help you ride to the top while maintaining the same speed. Pressing the gas hard while going uphill can cause your tires to spin wildly and get stuck in the snow. If it’s slippery, a situation like this might lead to sliding back down the hill and putting yourself and others at risk.
As the saying goes, “an ounce of prevention is worth a pound of cure.” Cold weather working conditions set the stage for countless safety hazards, many of which can lead to painful and debilitating bodily injuries, including fatality. Rather than responding to cold illnesses after they’ve already set in, prepare ahead and prevent them from happening to begin with.
When it comes to dressing properly for the cold, layering is by far the most effective technique. The greatest benefit of layering is its functionality and flexibility due to the fact that you’re wearing, well, layers. As working conditions change – fluctuations in atmospheric temperature throughout the day, as well as body temperature as work becomes more or less strenuous – you can add or remove layers as necessary in order to maximize comfort, as opposed to working with a single layer that doesn’t give you any control over temperature regulation. Being able to make these adjustments on the fly and respond to changes makes it easy to stay safe and compliant.
The basic, go-to layering system is comprised of three layers: an inner layer which manages moisture and perspiration, a middle layer for insulation and trapping heat, and an outer layer which acts as a protective barrier against the elements, such as snow and wind.
To be the most effective, each layer needs to work in synergy with the other, which means construction and material are important factors to consider during selection.
Layer 1: Moisture is the primary enemy of warmth. Body heat is transferred to moisture at the skin’s surface, which is then carried away through convection by evaporation. This principle is most commonly connected to sweating, a mechanism the body uses to regulate its temperature and expel excess heat. Because you’ll both be trapping heat through layering, and increasing activity as you work, chances are you’ll break a sweat. To combat this and minimize moisture, your first layer of clothing should be made of a material that can soak up moisture while still maintaining its thermal properties. Wear inner garments made of wool, silk, or other animal fibers, or synthetic fabrics such as polypropylene (most known for Long John’s or thermal underwear).
Layer 2: Your middle layer should be designed for insulation, trapping warm air close to your body. Animal fibers such as wool and silk, goose down, and synthetic fleece are all safe options.
Layer 3: Another enemy of warmth is wind, which tends to work in tandem with moisture by carrying the natural heat which radiates from your skin away from your body. This forces your body to work to replace that heat, lowering your core temperature overall. Additionally, strong winds can rapidly lead to frostbite and other cold-weather injuries. With this in mind, when selecting your outer layer, choose fabrics which protect you from the elements. Windproof, water-resistant garments work best, but keep in mind it should still allow for some ventilation to prevent overheating.
For your inner two layers, avoid cotton. Cotton will trap moisture and become overburdened, and isn’t conducive to thermal management.
For your inner layer, also avoid down. While down has incredible insulating properties and is great for staying warm, those properties are all but completely neutralized when it becomes wet.
Avoid tight-fitting clothing. A tight fit will restrict blood circulation, limiting your body’s ability to carry heat to the extremities.
Consider the nature of your job when selecting exactly what sorts of garments you’ll select. Loose accessories such as straps, or even scarves, can become caught in moving machine parts. Strive to choose a combination of garments which work together to achieve freedom of movement, breathability, and comfort.
Remember when working outdoors, cold weather season often comes with reduced visibility due to snow and fog. An outer layer with high visibility properties can not only increase safety on the job site, but also assist rescuers in locating you in the event of an emergency.
It’s easy to spend so much time thinking about your legs and torso that you forget about your extremities. Double layer your socks (again avoiding cotton) and wear insulated, waterproof boots. Gloves are important, but be sure to select them with your job in mind. Mittens are better for warmth, but aren’t always practical when precision work is required. Consider fingered gloves with mitten attachments so you can adjust on the fly.
Cover your face and mouth with a knitted, wool (or other animal fiber) mask during extreme cold and winds, as the cheeks and nose are especially prone to frostbite and chilblains.
The hat you use should cover your ears. A lot of heat escapes from the head, so don’t skip this accessory.
It’s a good idea to bring backup layers with you to the work. If you’re sweating excessively and your inner layer becomes so bogged down it’s no longer doing its job, you’ll want a replacement you can change into as necessary.
Standing snow is extremely reflective. Although it’s not a matter of warmth, don’t leave your eyes out of the equation. The sunlight reflecting off of the snow (and subsequently off of nearby reflective metals), even with cloud cover, can be just as harmful as direct rays. And it’s not just about protecting your eyes themselves – snow glare can be incredibly debilitating while performing safety-sensitive and hazardous operations.
The summer season is winding down, and as colder temperatures move in, workers face exposure to cold-related safety hazards.
Certain workers may be more susceptible to these sorts of hazards–such as those working outdoors and without shelter, those working indoors with poor insulation or no heat, and those working in geographical regions where temperatures dip into below-freezing digits.
However, other factors can contribute to cold-related hazard risks, such as increased wind speeds and moisture. Cold affects the body primarily by lowering the core body temperature. When someone is exposed to low temperatures for a prolonged period, the body’s stored energy will gradually deplete and result in a condition known as “hypothermia.”
This is a very dangerous illness, made worse by the fact that low body temperatures can adversely affect the brain.
Workers who cannot think clearly may not be aware of their condition, making them unable to recognize or properly respond to the onset of hypothermia. Water and moisture are major contributors to this condition because water removes heat from the body 25 times faster than air, and can quickly lead to hypothermia.
Hypothermia can occur from immersion in water with temperatures as high as 21°C, putting those performing work in even relatively temperate climates at risk. Moisture is also responsible for “trench foot,” which occurs when the feet are exposed to wet, cold conditions for long periods.
Other common cold-stress injuries include frostbite and chilblains. Chilblains can occur (based on moisture and wind conditions) at temperatures as high as 15.5°C. Frostbite can cause freezing damage so severe, it may lead to amputation.
In order to address cold-stress injuries in the workplace, employers need to create a thorough prevention program that includes training on risks, prevention, symptoms, monitoring, treatment and proper use of tools (such as access to warm liquids, warm rest areas, first aid kits, and personal protective equipment, including selection of work clothing). The best time to ensure your cold-stress prevention standard meets the needs of your employees is now. Safety Services Company can help design a program specifically tailored to your business.
Every year workers are killed or seriously injured while performing snow or ice removal from the rooftops of commercial, residential, and other building structures. Snow removal operations are often performed under extreme weather conditions by workers who may have little experience or training on the hazards of the job which is why having a safety manual can become very important.
Snow removal may be necessary to prevent overloading and collapse or for construction or repair of decking or roofs. Workers often climb directly onto the roofs or structures and use shovels, snow rakes, or snow blowers to remove ice and snow. Other times these operations are done from aerial lifts used to access roofs and apply de-icing materials, or from ground level using ladders and snow rakes.
Falls are the most common cause of worker fatalities and injuries during rooftop snow removal. Workers can fall off roofs, through skylights, or from ladders and aerial lifts.
In addition to falls, workers removing snow, face other significant hazards including:
Injuries from using snow blowers and other mechanized equipment
Collapses or tip-overs of aerial lifts
Becoming engulfed by falling snow
Being shocked/electrocuted from contacting power lines or using damaged extension cords
Frostbite or hypothermia
OSHA requires that employers plan and use the safe work practices to protect workers during snow removal activities. Before snow starts to accumulate, think about what will be needed to remove snow from roofs or other elevated surfaces safely:
Can the snow be removed without workers going onto the roof?
Are there any hazards on the roof that could become hidden by the snow and will need to be marked so that workers can see them (skylights, roof drains, vents, etc.)?
How to remove snow based on the building’s layout to prevent unbalanced loading?
Determine the maximum load limit the roof can handle, and compare that to the estimated combined weight of the snow, the removal equipment, and workers on the roof
What tools, equipment, PPE, clothing, and footwear will workers need?
What training will workers need?
How will snow removal equipment be moved to the roof?
How will you protect workers and others on the ground from the snow and ice being removed?
Remove Snow Without Going on the Roof
Whenever possible, use methods to clear ice and snow that don’t require workers to go on the roof, such as using ladders to apply de-icing materials or using snow rakes or draglines from the ground.
Use Required Fall Protection
Falls cause most of the deaths and severe injuries that occur during snow removal operations. OSHA requires employers to evaluate and protect workers from fall hazards when working at heights of 4 feet or more above a lower level (1910.23), 6 feet, or more for construction work (1926.501).
If workers must access roofs and other elevated surfaces to clear snow:
Train them on fall hazards and the proper use of fall protection equipment,
Ensure all workers use their fall protection equipment when removing snow in areas that are not adequately guarded
Have workers put on their fall protection equipment before accessing the roof
Have a written rescue plan in case a fallen worker becomes caught by a fall protection system
Remove or mark rooftop or landscaping features that could present trip or fall hazards
Workers at ground level removing snow from the roof, and bystanders, can become trapped under snow falling from roofs and suffocate. Snow being removed for a roof can be dangerous. One cubic foot of dry snow weighs about seven pounds, while a cubic foot of wet snow weighs anywhere from 12 to 18 pounds. To protect personnel from removed snow:
Identify a safe work zone in the area where snow is being removed to keep the public back 10 feet from where snow is expected to fall
Instruct workers to wear eye and head protection when removing snow and ice.
Instruct workers using snow rakes and draglines to remove only small amounts of snow at a time.
Effective planning and preparation can protect workers and the public from injuries during snow removal work.
This winter has been one of the worst for much of the U.S., with near-record snow, ice, and many other weather hazards. Walking in winter weather can be particularly dangerous.
Snow is bad enough, but ice and icy conditions can present a far greater hazard to your health. Snow is easy to see, remove, and does provide some traction. Ice, on the other hand, can be hard to see and dangerous, especially if you’re on foot.
The last thing you want to do is fight the weather, get to work, park your car, and then injure yourself when you get there. Slipping and falling on parking lot and sidewalk ice injuries in are common, and can cause serious injuries. Broken arms, wrists, and hips are far too common in snowy and icy conditions.
Here are some general tips to help companies and employees stay safe when conditions are icy:
Employers should clear snow and ice from walking surfaces and spread deicer as quickly as possible after a storm.
Employees should wear footwear that has good traction and insulation. Avoid wearing boots or shoes with smooth leather or plastic soles and heels. You should always wear shoes or boots made of non-slip rubber or neoprene with grooved soles when walking on snow and ice.
Wear a heavy, bulky coat that will cushion you if you should fall.
Wear a bright colored or reflective clothing so drivers can see you.
Keep warm, but make sure you can hear what’s going on around you.
During the day, wear sunglasses to help you see better and avoid hazards.
Walk like a penguin
In cold temperatures, assume that all wet, dark areas on pavement and sidewalks are slippery and icy. A thin layer of moisture can freeze on cold surfaces, forming a nearly invisible layer of black ice that can look like a wet spot on the pavement.
Walk in designated walkways whenever possible. Taking shortcuts over snow piles and other frozen areas can be dangerous. Avoid walking in the street if at all possible, icy streets are slippery for cars too, and they’re much more difficult to stop.
When walking on ice, angle your feet out, like a penguin, this will increase your center of gravity.
Lean slightly forward and walk flat-footed to keep your center of gravity directly over your feet.
Taking short steps will help you keep your balance
Extend your arms out to your sides to maintain balance. If you must carry a load, try not to carry too much; leave your hands and arms free to balance yourself.
If you do carry something, carry it in your dominant hand. This can help prevent you from using your dominant hand break your fall, and avoid injuring your hand, wrist, or arm.
Keep your hands out of your pockets. Putting your hands in your pockets while walking may keep them warm, but it decreases your center of gravity, balance, and increases your chances of slipping and falling.
Watch where you’re walking, focus on the path in front of you, and take your time
When walking on stairs always use the hand-railings and plant your feet firmly on each step.
It’s easy to lose your balance when getting into or out of your car, use the vehicle to help support yourself.
Look at the ground while you’re walking, don’t end up slipping on ice that we could have seen if we had been looking.
Walking on a slippery floor can be just as dangerous as walking on ice. Keep these tips in mind when entering a building:
Melting ice or water on the floor can make it slippery.
Watch for floors and stairs that may be wet and slippery, walk carefully by outer doors.
Determine the best path to take to get to your destination and take a little extra time to get there
Be sure to use floor mats when entering a building to remove moisture from the soles of your shoes – this will help protect you, and others, from having to walk on wet or slippery surfaces
Winter weather can be irritating enough without adding injury to the equation.
Cold-related injuries can be costly to a business, costly to treat, painful, and in severe cases, fatal. It is an employer’s responsibility to develop a written cold-stress prevention program that provides workers with the knowledge to work safely in cold temperatures.
While a given prevention program will need to be tailored to your specific workplace, use these basics to get you started. Following are elements of cold safety to include in your program:
The Right Gear
Multiple layers of loose clothing create an insulating effect. Avoid tight clothing as it inhibits circulation. Just remember, clothing that is too bulky may restrict movement and become a hazard of its own.
Choose boots that are both insulated and waterproof. Cold environments where snow and/or ice is involved will require footgear that provides traction to protect against slipping and tripping.
The head, hands, and feet lose heat rapidly. Wear a hat, gloves, and layered socks.
Additional protective gear may be necessary depending on weather conditions and work performed. Consider full face protection or waterproof pants, for example.
Moisture carries heat from the body at an accelerated rate (24 times faster, as a matter of fact). If sweating from intense work activity – or any other source of moisture – dampens clothes, workers should change immediately. Always carry a change of dry clothes onsite.
During breaks, move into a warm location. Time spent exposed to cold temperatures between breaks should be limited.
When possible, schedule all work that isn’t urgent to be done during the warmest times of the day when the sun is high and wind conditions are calmer.
It’s important workers are scheduled in teams of at least two. The buddy system allows workers to monitor each other’s conditions and behaviors, watching for signs of cold stress and taking appropriate action when necessary. Appropriate action would include escorting the affected worker to a heated area, performing first aid (or dialing emergency medical assistance), and contacting management.
Working in cold weather depletes the body’s resources more quickly than normal. Taking frequent breaks will help worker’s avoid fatigue, and eating foods high in calories and carbohydrates will contribute to energy resources. Stay hydrated, but avoid caffeine and alcohol. Consider providing employees warm beverages.
Having radiant heaters in place may help workers stay warm while on the job, but beware of the hazards of carbon monoxide — never run heaters, generators, or other carbon monoxide-generating equipment in an enclosed area.
When possible, use engineering controls to alter the worksite appropriately. Erect wind guards and insulate any exposed metal designed for worker contact.
Training and Knowledge
Being properly trained in the characteristics and symptoms of cold-related injuries is very important. It helps workers recognize changes in their own body, and coworkers. Training should include knowledge of cold-related injuries, what their symptoms are, and applicable first aid. The most common cold-related health concerns are hypothermia, frostbite, and trench foot.
Hypothermia occurs when the body’s core temperature drops to approximately 95°F (normal temperature is 98.6°F). It is a result of body heat being depleted faster than it is generated, and is a very serious condition. Hypothermia can have long-lasting health implications, and if left untreated, may result in death.
One of the most disconcerting hazards of hypothermia is it affects the brain, often causing the victim to be unable to think clearly. As a result, a worker may not be entirely aware it’s happening (bringing us back to the importance of the buddy system).
The symptoms of hypothermia evolve over time. In its early stages, victims may shiver, show fatigue, be confused or disoriented, and have a loss of coordination. Later on, shivering will cease. Skin may become a pale blue color and their pulse and breath will slow. At this point, loss of consciousness is possible.
If someone is showing symptoms of hypothermia, notify the nearest supervisor and contact medical assistance. Move the victim to a warm area. Remove any wet clothing and warm them gradually — do not try to shock their body temperature up, as that can cause additional damage. Wrap them in dry layers of blankets and use an electric blanket or skin-to-skin contact. If they are conscious, give them warm beverages. If they have fallen unconscious and have no pulse, perform CPR until medical professionals arrive.
Frostbite is the result of skin losing moisture and freezing. Blood vessels are constricted and damaged, and in severe cases, amputation of the affected area is required. The average temperatures at which frostbite occurs are under 30°F, but keep in mind that wind chill may be a factor.
This affliction favors the extremities, such as the ears, face (nose, lips), fingers, and toes where body heat is lost first. Early symptoms often include a waxy appearance on the affected tissue. Numbness or sharp prickling sensations are also common, although pain is not always prevalent. Later symptoms are hardness of the tissue and blistering, at which case the frostbite has become a severe medical emergency.
If a worker has frostbite, take them to a warm area and contact medical assistance. You may wrap the affected tissue in a warm cloth, or immerse it in warm water (maximum 105°F). Two things to remember while waiting for medical response: do not attempt to warm the tissue if there is a chance that it will get cool again, and do not rub the area to warm it. Both cases can cause severe tissue damage.
Trench foot is often considered a less severe form of frostbite, caused when feet are immersed in cold water for extended periods of time. While its severity may be less, prolonged immersion and lack of treatment may, like frostbite, lead to amputation. Trench foot may occur at water temperatures as high as 50°F.
Symptoms may include itching, numbness, tickling, swelling, and discoloration (red, blue, or black, depending on the severity).
Move trench foot victims to a warm location and contact medical assistance. Immerse the foot in warm water and then wrap it in dry cloth or bandages.
