Subsection 3: Electrical installations and precautions against static electricity

All buildings where pyrotechnic activities are carried out are deemed to be premises or locations exposed to fire risks within the meaning of article R. 4215-12. In the case of an explosive atmosphere, they are also deemed to be exposed to explosion risks within the meaning of the same article. No overhead power lines with bare conductors may overhang the installations of the pyrotechnic enclosure.

The electrical installation in each building or premises where pyrotechnic activities are carried out must include a device enabling the power supply to the building or premises to be cut off in an emergency. The operating mechanism for this device is located outside and close to the building or premises. This device must be easily recognisable and easily accessible.

When handling explosive substances or articles known to be sensitive to static discharges, in order to reduce the possibility of potential discharges, such handling should be organised in such a way as to encourage the flow of static charges and to ensure the same level of electrical potential at all points in the pyrotechnic workstation. Workers should wear working clothes and personal protective equipment which prevent the build-up of electrostatic…
