Working in cold weather can be difficult, and it can also be hazardous to your health. In this blog post, we will discuss the dangers of working in cold weather, as well as some tips for avoiding cold stress.

While it’s known as the Sunshine State, some parts of Queensland’s south can have extreme colds that can cause health and safety issues for workers, particularly those who work outdoors.

What is Cold Stress? 

Cold stress is a type of occupational hazard that can occur when workers are exposed to cold temperatures, wind, or moisture. Cold stress can lead to serious health problems such as hypothermia, frostbite, and trench foot. In extreme cases, it can even be fatal.

There are several factors that contribute to cold stress. The first is the temperature of the environment. If the temperature is below freezing, it puts workers at risk for hypothermia, which is when the body loses heat faster than it can produce it. The second factor is wind chill, which occurs when wind speeds make the air feel colder than it actually is. Finally, moisture can also contribute to cold stress, as wet clothing can make the body lose heat more quickly.

Cold Stress or Just Cold?

Working in cold weather can be uncomfortable and unpleasant however there is a difference between being cold and a condition that threatens health and safety. The risk of cold stress increases with age, poor health and certain medications. 

When workers are involved in tasks with prolonged or repeated exposure to cold, they must be familiar with the early symptoms of hypothermia and frostbite.

Early symptoms of hypothermia:

• Shivering
• Confusion
• Slurred speech and difficulty thinking clearly
• Clumsiness
• Drowsiness, 
• Exhaustion. 
• Numbness in hands or fingers
• Loss of fine motor skills, particularly in hands—workers may have trouble with buttons, laces, zips
• Irrational behavior—such as a person discarding clothing.

If you experience any of these symptoms, it’s important to get out of the cold and into a warm environment as soon as possible and seek medical help. Hypothermia can be fatal if it’s not treated right away.

Early symptoms of frostbite or trench foot:

• Numbness, tingling, and pain in the affected area.
• Red or pale skin 
• Blue lips
• Sluggishness. 

If you or someone you know experiences any of these symptoms, get out of the cold and into a warm environment and seek medical help immediately. Frostbite can lead to permanent tissue damage if it’s not treated right away.
