8.0 Maintenance of the AF-X Fireblocker
For the duration of its use the AF-X Fireblocker must be subjected to the following inspections and maintenance,
performed by qualified, i.e. in accordance with local laws and norms, technical staff:
•
Check the extinguishing unit for any damage
•
Check whether the sticker on the discharge opening is still secure
•
Check the log
•
Measure the resistance
•
Check whether the projection is in accordance with delivery
•
Check the mounting brackets and attachment
•
Check whether the label on the extinguishing unit is securely fastened
•
Check the unit’s life span, see expiry date on the label of the AF-X Fireblocker
NB the entire system, including all parts, must be checked regularly in accordance with the suppliers’ guidelines
and/or local laws.
The AF-X Fireblocker Carbon series have been designed for a service life of 15 years. Please be aware that
the extinguishant contains materials that have a relatively low melting temperature. These materials increase
the extinguishant’s efficiency, but it is therefore important to always ensure that the AF-X Fireblocker is not exposed
to temperatures that are outside the normal operating temperature range of -20 and + 50 degrees Celsius, as
stipulated in this manual. The service life of the AF-X Fireblocker is monitored by the producer by testing product
batches on a regular basis.
9.0 Residue removal, disassembly, waste and the environment
9.1
Introduction
Upon activation, the SAFCO converts into rapidly dispersing aerosols, consisting of solid micro particles suspended
in gas.
The concentration of solid particles suspended in the aerosol phase is a few milligrams per m
³
. The particles are
water and moisture-free and, after passing the hold-time, settle as dust in the protected area. The dust should be
removed before it absorbs moisture.
Thorough cleaning by removing all aerosol particles prevents the aerosol and combustion residue suspended in the
air from absorbing moisture so the particles cannot react any longer to electronic parts, metals, etc.
Should the aerosol particles remain on the surfaces for an extended period of time, they might absorb moisture,
thus risking a reaction of the moisture to metals (particularly uncoated metals), possibly resulting in oxidation.
After activation it is recommended to have delicate metals and equipment cleaned by a specialised company.
9.2 Residue removal
See and follow chapter 7 of the SDS that is added as Annex 3 to this manual for necessary personal protection
before entering the room.
-
Although the aerosol in itself is harmless, ventilate the area for at least 30 minutes after activation. Do not
enter the area until after it is sufficiently ventilated.
-
To avoid any unwanted side effects, remove the residue (within a couple of hours).
-
Vacuum the dry residue from the floor and metals using a vacuum cleaner.
-
Dust the residue from electric parts using a fan or ventilator.
-
Use special sprays or dry ice cleaning suitable to remove residue from electronic parts.
NB although the residue is harmless to man and the environment, it is recommended to wear a dust
mask during cleaning activities because of particulates.
Always contact your distributor or dealer after AF-X Fireblocker activation; they will assist you in
renewed projection as well as the correct reconditioning and cleaning methods of the area
concerned
