In the field of fire extinguishing, the following guidelines are usually recommended, and here we are examining which one has
a higher safety margin for fire extinguishing:
Aerosol fire extinguishing system: This system is considered by employers according to its advantages.
The first advantage of this is the need for plumbing and installation in a wall package or in a shelf, but given the fact that the Ariocle package
at discharge time The heat of 200 degrees Fahrenheit is released, it burns and damages the documents and is practically inefficient.
In the next advantage, it is considered that the aerosol acts as a topical and does not require the discharge of all its cylinders.
But considering that in a large document hall, one can not guess at all, a ghosts created and burned in a center part of the documentary,
because fire class A fire is a fire and can be reactivated again. Do not re-activate because Aerosol is not suitable for fire extinguishers in any
way according to clause 220.127.116.11 of the NFPA standard of 2010 and 2013 editing.
Standard NFPA2010 Standard No. 7,4,2,1 AeroSeal Fire Extinguisher Able to fire extinguishers in fire classes A
(other than fire extinguishing materials) Fire Class B (other than those containing vapors and flammable particles in the air) Class C fire
(in limited cases and only if tested).
So, given the deep burning of the product, we should consider the system TOTAL FLOODING, ie all fire extinguishers in the room are discharged.
In the whole term, the volume of the room is filled with exhaust ventilation.
If this occurs despite the presence of an aerosol: 1. The level of vision in this room reaches zero; 2. The solid particles suspended after discharging,
in the form of larger grains than solid particles in the air, in the presence of human agent into the existing lung Live penetrates and causes acute
In accordance with clause 4.2.3 of the NFPA2010 standard, 2013 editing The limitation of the presence of people at the Ariozel drainage site:
Personnel should not be shut off at discharge or after discharge. Aerosol will be present at the site.
If necessary, arrivals at the time of the aerosol evacuation must be used by trained people with protective equipment such as air bags
(respiratory capsules) and masks and special coatings.
Aerosol is a disposable package and can not be reused or recharged after recharging. (Not cost effective) Because of the above,
as well as the effect of its materials on the product, such as adhesion - corrosive - the creation of oil Black - and the need for cleaning up to 24
hours after fire extinguishing as well as possible damage to any external insurance company such as VDS or FM is not willing to give a certificate
to this product.
