| forced ventilation | must be used when welding zinc, copper, mercury, lead |
| eye protection | must be worn at ALL times in the weld shop |
| Why is it important to keep the work area clean? | safety, production - get more done |
| conditions for forced ventilation | gas, dust, smoke, fumes |
| avoid electrical shock when welding | stay dry, inspect and repair cracked insulation on hoses |
| ventilation in your shop | forced and natural |
| fire extinquisher type, location | multi purpose, entrance and exits |
