FIRE ACTION PROCEDURE
WARNING!
Always comply with the legal fire safety procedures
and respect instructions from the fire safety
coordinator.
ATTENTION!
The FlameShield extinguishing material is extremely
fine. In case of fire, it may seem like smoke escapes
through the seams of the filter system, but most
probably it concerns the extinguishing material which
is fully harmless to environment and human.
WARNING!
To avoid re-ignition of the fire and to prevent
consequential damage, keep filter closed for at least
15 minutes.
WARNING!
During inspection and maintenance, always use
Personal Protective Equipment (PPE) to avoid injury.
This also applies for persons who enter the work area.
ATTENTION!
Do
not
start maintenance before receiving permission
from authorized personnel.
CAUTION!
The FlameShield modules get hot from the release of
the aerosol. Allow the modules to cool down before
replacement or use protective gloves.
