Is DPF 2400 OSHA approved/safe to put on hard hats for uses in the electricity field?

DPF 2400 is not OSHA approved for electrical work.

DPF 2400 is not OSHA approved and we have not measure the film conductivity.

It really depends on what industry the hard hat is going into which will determine the specification that the hard hat has to meet. OSHA is very specific in the use of decals and stickers used on hard hats.

Engineer Grade decals are currently in use for some industries that require the use of head protection. See MSA web-site for hard hats.

Some of the reasons why they frown on the use of stickers/decals is that it could hide a defect or crack in the helmet and or they don't want a safety device used for advertising or non-safety use.

My recommendation would be to ask the customer what industry and applicable specification they are looking to meet. Also, I believe there are different requirements based on what country the hard hat is to be used in.
