Er det å legge inn knivkontakter på EX-I/egnesikkert utstyr å regne som varmt arbeid klasse B:

"Hot work class B in classified areas is classified as:

Work with equipment that constitutes a potential ignition source and that in the event of a fault or malfunction may constitute an effective ignition source which may ignite an explosive atmosphere, i.e. equipment that does not have a sufficient surface temperature and/or does not give off sparks, an open flame or electric arc, or in any other way release sufficient energy to ignite an explosive atmosphere or flammable liquid during normal use, but which when used incorrectly or in the event of a fault or malfunction may constitute an effective ignition source."
