Any job or task comes with its own unique risks and rewards, but some are more dangerous than others. You don't have to be a contractor in Iraq or a lion tamer in order to put yourself in harm's way. You can hurt yourself simply by working in a walk-in freezer. This chilly chore poses much greater hazards than merely making you crave a fourth cup of coffee. Due to the subzero temperatures, the potential for ice on the floor, and the possibility of the freezer door locking, there are certain precautionary measures you should always take while working in a walk-in freezer.
Exposing yourself to hostile elements for any elongated period of time means that you are putting yourself at risk. Dress appropriately. This should definitely involve a heavy winter coat, full-length trousers, non-skid shoes and gloves. To protect even more of your skin, also consider wearing a ski mask, a scarf or a thick bandanna tied around the lower half of your face.
Use a door stop. If the freezer door has any kind of locking mechanism, be sure to wedge this beneath or against it in order to prevent it from shutting completely and potentially locking you inside.
Work in pairs of two or more. This is especially important if the freezer door has a lock on it. That way, one person can be outside the freezer and one person can be inside at any given time. Or, if one person trips and falls, the other can help him or her out.
Tread carefully. Non-skid shoes are great for making you less prone to slipping on wet or icy surfaces. However, they are not fool proof by any means. So while you are working in the freezer, look where you're stepping and be aware of any slippery conditions around you.
Take breaks. Regardless of how well bundled up you are, your body will still eventually react to the freezing temperature, quite possibly without you even recognising it. So if you have to work in the freezer for hours at a time, make it a point to stop and seek out a warm environment for a few minutes every fifteen minutes or so. Drinking a hot beverage during these breaks is also strongly recommended.
