Requirements
• In addition to a room-protection system, locally
acting fire extinguishing systems (installed fixedly
and allocated to the object) shall give effective
protection for the hazard zone between the outlet
of coating materials and the workpiece. It shall be
proved for each individual case, if the aspects of
the locally acting fire extinguishing systems and the
room-protection system could be satisfied by one
fire extinguishing system.
• Electrostatic spraying systems shall be equipped
with locally acting automatic fire extinguishing sys-
tems which are actuated immediately in case of
fire. When the fire extinguishing system has been
activated, the high voltage supply, the supply of
coating materials and the pressurized air shall be
cut-off automatically.
EN 13478 shall be observed.
It shall be checked in each individual case, whether
a present room-protection system is also able to fulfill
the function of a locally acting automatic fire extin-
guishing system.
• Where conductive parts are used for the coating
material supply system, these parts shall be either
bonded to earth or connected with the high voltage
supply system so that the potential level is invari-
ably identical with that of the electrostatic spraying
system.
• Insure all earthed items are outside the safe use
distance of 204mm.
• In compliance with EN 12215: 2004
