After analyzing the hazards, see if there is any possibility of Hot Work Alternatives. An alternative Hot Work method is termed “Cold Work”.

1) Can the job be completed with cold work? An example of cold work is performing repairs with another method instead of using a heat producing tool. If yes, a Hot Work permit is not

required.

2) Can Hot Work be performed in a designated area (e.g. maintenance or welding shop). If yes, then a Hot Work permit is not required.

3) Is the proposed work to be performed in a non- permissible area? Hot Work AND PERMIT ARE NOT AUTHORIZED in a non-permissible

location.
