It’s cold weather season, which means it’s time to be extra careful at work as a mechanical plumber, or construction worker. The cold weather might seem innocent enough, but it can be detrimental to your health and career. Not only does cold weather weaken your immune system and make you sick, it can also cause frost bite if you’re not protected correctly. You need to keep those fingers and toes for work!

Here are three ways to practice cold weather safety at work this winter and every winter after that.

Wear appropriate clothing for work

When working as a plumber or construction worker who spends a lot of time outside, wearing the appropriate clothing is important. Check the news to see what the weather will be for the day and dress accordingly. Heavy socks, multiple layers, flannels, gloves and long johns are all good ways to stay warm without wearing bulky clothing that can get in the way of your labor. Wool is one of the best fabrics you can wear to stay warm, and polyester is great for thin layers.

Stay hydrated

Just because it’s not warm outside doesn’t mean you shouldn’t stay hydrated. If you’re busy working, that means you’re burning calories and perspiring. Also, standing next to heaters continually can cause dehydration. It is recommended that women consume 91 ounces of water per day, and men 125 ounces. You also get water from eating fruit, vegetables, coffee and tea—but drinking water is always best. Keep a Thermos on you at all times and back up water in your car.

Be careful using gloves

It’s vital to keep your hands protected from the cold during the winter, but it’s important to note that when using a pipe threader, your gloves can get caught and wrap around your fingers. Avoid bulky gloves or remember to take your gloves off when using a pipe threader.
