During metal work or woodwork activities in the workshop, everybody should be at alert to give first aid because a little carelessness can lead to an accident. Sometimes, the hazards and accidents could be very dangerous and life-threatening. In order to salvage the life involved, there is need to provide first aid fast and to have first aid skills.

Applications of Simple First Aid 

The cases of accidents where first aid treatment is used include:

1. Simple cuts which cause bleeding: The bleeding is drained with cotton wool and iodine. Penicillin ointment is put on before it is covered with plaster.   
2. Snakebites or scorpions’ stings: These can be treated by tying a rope above the bite point. A razor blade is used to make one or two marks on the bite points so that the poison can flow out 
3. Respiratory   problem: The victim is made to lie down face up. The belly of the victim is pressed gently to release water through his mouth and nose. If the patient still does not breathe, try a mouth to mouth resuscitation by putting your mouth on his mouth and blowing air into his lungs forcefully.

6. Broken arms: Clean and dress wound if any. Splint (bandage with ruler or stick). Go to the hospital.
7. Hot object and hot palm oil: Clean gently with Savlon and then apply gentian violent (G.V. Paint) or dermacin cream, give antibiotics.
8. Electric shock: Firstly, switch off the source of power supply. The victim is then made to lie down to rest for a while, give milk if necessary. 
9. Febrile convulsion: This happens when body temperature is too high. Tepid sponge (mop with ordinary water). Protect the tongue with spoon covered with bandage in the mouth. Do not give any drug.
