Typically, you would be placing electrical switchboard matting in front of high voltage equipment. Like, switch gears, motor controls etc. You place them in front to ensure that the current doesn’t flow into the operator’s body bottom to the top.
In OSHA’s switchboard matting regulations, you would find that without proper insulation, you are basically running a risk of an unexpected inspection.
Moreover, you are not following the electrical safety guidelines, you would be not just risking your taskforce’s life but your eligibility to function in the industry.
Paying out in millions for a damage claim and insurances and legal fees for being prosecuted, you would rather just be safe than sorry.
