Working in the Cold
Depending on where you reside and work this season, Old Man Winter might be knocking on your door, bringing you snow, ice, and chilling temperatures. For those in warmer areas of the country, it may be difficult to imagine some winter weather extremes. For instance, according to the NOAA National Climate Extremes Committee, the existing record for lowest temperature in the United States was -80°F (-62.2°C) in Prospect Creek, Alaska, in 1971. Luckily, most workers will not encounter conditions quite so extreme.
Workers exposed to extreme cold or who work in cold environments may be at risk for cold-related illnesses and injuries. Susceptible workers, such as those working without shelter, outdoors, or in an area that is poorly insulated or without heat, may be put into a dangerous situation when cold weather prevails. What constitutes cold stress and its effects can vary across different areas of the country. In regions relatively unaccustomed to winter weather, even near freezing temperatures can put unaccustomed workers at risk.
Whenever temperatures drop decidedly below normal and as wind speed increases, heat can more rapidly leave the body. If workers are unable to keep warm, these cold conditions may lead to serious health problems, such as chilblains, trench foot, frostbite, and hypothermia. Hypothermia in particular, can be deadly. If a worker experiences an abnormally low body temperature, the brain is affected, making it difficult or impossible to think clearly or move well. This makes hypothermia particularly dangerous because a person may not know it is occurring and may be unable to take actions to warm themselves or seek medical care.
There are a few recommendations that employers can follow to protect workers from cold stress:
- Schedule routine maintenance and repair jobs in cold areas for warmer months.
- Schedule cold jobs for the warmer part of the day.
- Reduce the physical demands of workers.
- Use relief workers or assign extra workers for long, demanding jobs.
- Provide warm liquids to workers to consume.
- Provide warm areas for use during break periods.
- Monitor workers who are at risk of cold stress.
- Provide cold stress training that includes information on the following:
- risk factors
- the importance of monitoring yourself and coworkers for symptoms
- first aid
- personal protective equipment
In addition, workers should avoid exposure to extremely cold temperatures when possible. When cold temperatures cannot be avoided, workers should follow these recommendations:
- Wear appropriate clothing.
- Wear several layers of loose clothing. Layering provides better insulation.
- Tight clothing reduces blood circulation. Warm blood needs to be circulated to the extremities. When choosing clothing, be aware that some clothing may restrict movement, resulting in a hazardous situation.
- Make sure to protect the ears, face, hands, and feet in extremely cold weather.
- Boots should be waterproof and insulated.
- Wear a hat; it will keep your whole body warmer. Hats reduce the amount of body heat that escapes from your head.
- Move into warm locations during work breaks; limit the amount of time outside on extremely cold days.
- Carry cold weather gear, such as extra socks, gloves, hats, jacket, blankets, a change of clothes, and a thermos of hot liquid.
- Include a medical and environmental thermometer and chemical hot packs in your first aid kit.
- Avoid touching cold metal surfaces with bare skin.
- Monitor your physical condition and that of your coworkers.

The second annual Safe + Sound Week will be held August 13–19. The event is a nationwide effort to raise awareness of the value of workplace safety and health programs. These programs can help employers and workers identify and manage workplace hazards before they cause injury or illness, improving a company’s financial bottom line. Throughout this week, organizations are encouraged to host events and activities that showcase the core elements of an effective safety and health program, including management leadership, worker participation, and finding and fixing workplace hazards. For more information and to sign up for email updates, visit the Safe + Sound Week webpageExternal. NIOSH is one of the many cosponsors of this event.

New Infographic for NJ Fishermen on Dangers of Old Bombs in the Ocean
A new infographic on dangers in dredging old bombs from the New Jersey ocean floor was recently developed by the New Jersey Department of Health (NJDOH), Occupational Health Surveillance Unit, and the NJDOH, Food and Drug Safety Program. The infographic was developed in response to a 2016 incident where a New Jersey clam fisherman inadvertently dredged up old munitions from the seafloor off the coast of New Jersey. Per reports, a munition appeared on the conveyor belt during clam processing shipboard and was recognized as a “bomb” by a crew member who then threw it back into the water. The fisherman later developed painful blistering on the right lower and upper arms. The infographic was distributed to NJ shellfish dealers and harvesters and is available onlineCdc-pdfExternal.
Fire Fighter Falls through Floor and Dies at Residential Structure Fire—Ohio

As the fire fighter crawled into the structure, following a hoseline, the floor collapsed and he fell into the basement. The fire fighter was pronounced dead at the hospital.
Potential Bloodborne Pathogen Exposure in a City Police Department
HHE Program investigators found 13 needlestick injuries and 37 additional exposure incidents across a 6-year period in a force of about 1,000 officers. The police department had not yet adopted the city’s bloodborne pathogens exposure control plan. Investigators recommended using sharps containers for evidence collection and continued training on safe searching techniques. For more information click here.
Evaluation of Exposures in a Vape Shop
HHE Program investigators found low levels of two flavoring chemicals in air samples—diacetyl and 2,3-pentanedione. Chemical protective gloves were not always used when handling liquids containing nicotine. Investigators recommended not vaping in the workplace with e-liquids containing diacetyl and 2,3-pentanedione and training employees on proper chemical handling procedures.
