 During assembly and operation of explosion-proof equipment, the relevant regulations of i.e. BG-Chemie
about the use of equipment in area at risk from explosion, must be adhered to by the user/owner.
 Please make sure that external ventilation is sufficient.
 Please wear conductive shoes. Gloves should have a shunt resistance of < 10
 It is not allowed to take off clothes.
 The surface temperature of the devices could increase by a variety of external circumstances. For this
reason, the surface temperature is to be monitored.
 Avoid ignitable dust deposits.
 Remove dust deposits daily before commencing work and ensure that dust cannot settle between moving
