| Metal fume/dust hazards ||
* General hazards of fine dusts,
* Hazards of galvanized metal, properly preparing galv and cleaning it
* Why are we restricted to carbon steels? (Cr2O3, Al2O3, NiO, CuO etc.)
Line 46:
|| Metal dust and fume are long term health risks
|-
| Basics of plasma cutting ||
* What can be cut - Any metal, but safety issues on anything other than plain carbon steels
** Looking for any defects or damage
** Are the shields and gaurds in place?
** Checking compressor oil level
** Venting the compressor
** Are the regulators all the way out?
** Testing the compressor safety valve
** Are the hoses and cables in good condition?
* Connecting up the equipment, noting that the air source needs to be reasonable clean and water-free, what will happen if it isn't
* Torch safety, electrical hazards, air injection issues, firing out of grit and possibly parts of the head if damaged, must never be pointed at people
|| Basics of how the process works and is used
