Working in cold conditions is a very real risk across Canada in winter. It’s no surprise that this has been considered by safety professional and many guidelines for safe procedures in freezing temperatures have been recommended. It is recommended that there be a warm up shelter nearby in conditions exceeding -7 degrees Celsius.
Proper outerwear is expensive but well worth it when it comes to being outside in freezing weather.
Be aware that it is important to take your body into consideration. If you feel you don’t have proper equipment is is in everyone best interest that you are allowed to obtain proper gear before continuing work. No one is quite as useful after receiving frostbite.
