Most often you'll run up against smaller injuries - burns, nicks, cuts, and scratches. The danger here is in the fact that most men don't bother to get first aid for these minor injuries. But unless they are properly treated, these little injuries can develop into serious injection cases. Remember the old adage about a stitch in time. Work carefully but if you do get hurt or someone else gets hurt, get expert attention as soon as you can.
Time is often very important.
When any injury occurs - serious or minor be sure that it receives the right kind of treatment, as early as possible.
