Residue removal, disassembly, waste and the environment
8.1
Introduction
Upon activation, the SAFCO converts into rapidly dispersing aerosols, consisting of solid nano and 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 some time settle as dust in the protected area. The dust can easily be removed
before it absorbs moisture.
If thorough cleaning removes the aerosol particles before they can absorb moisture and combustion residue
suspended in the air, the particles cannot react 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.
8.2 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 it is mandatory 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
8.3 Disassembly after the AF-X Fireblocker has been activated
Please take the following steps when disassembling the activated AF-X Fireblocker:
Fully disconnect the unit from the fire detection system and make sure that it cannot be reconnected
inadvertently;
Disconnect the AF-X Fireblocker power supply wires and make sure they cannot be reconnected;
After activation the AF-X Fireblocker may still be hot; it is therefore recommended to wear heat
resistant gloves.
Be careful of your footing and observe local regulations concerning working
at height;
Unscrew the bolts and nuts holding the AF-X Fireblocker in the mounting bracket;
Gently take the AF-X Fireblocker out of its mounting bracket and place it on a stable base;
Upon the AF-X Fireblocker(s)’ disassembly, consult with the manager about reactivating the fire
detection and alarm system;
