The Avon CBRNCF50 canister meets the NIOSH CBRN APR standard at the 15-minute classification level (Cap 1), the EUROPEAN STANDARD, EN 14387 (A1B2E1K1 P3), and the relevant criteria specified in the NATO Triptych for protection against chemical and biological warfare agents in aerosol, liquid form.
It provides effective protection against all the gaseous agents specified in the NIOSH CBRN standard, as well as excellent performance against a wider range of both chemical warfare agents and Toxic Industrial Chemicals (TICs). A particulate filter element exceeding the requirements of NIOSH 42CFR84 P100 and EN 14387 (P3) is incorporated, ensuring effective performance against all dusts, mists, fumes, biological agents (bacteria, virus, fungal spores etc), including radioactive dusts. When combined with an appropriate chemical protective mask, the CBRNCF50 filter canister protects the face, eyes and gastrointestinal tract of the wearer against known chemical and biological agents in aerosol, liquid and vapor form including:
The protection against many Toxic Industrial Chemicals (TICs) includes, but is not limited to: organic vapors with a boiling point over 65°C, chlorine, hydrogen sulfide, sulfur dioxide, formaldehyde, nitrogen dioxide, phosgene, phosphine, hydrogen chloride, hydrogen fluoride, methlyamine, and ammonia.
The canister body is made of a modified polyphenylene etherpolystyrene blend (PPE&PS), which is a high quality engineering construction polymer. It provides a very robust product which is extremely durable against shock and impact in operational use. The canister body is black in color and has a spark finish to reduce reflection. Gas adsorption is by chrome free activated charcoal impregnated with metallic salts and other compounds to provide a balanced performance against both physically and chemically adsorbed species. The high efficiency filter element is made of PTFE, PET/PE. The CBRNCF50 is entirely non-ferrous and non-magnetic.
Against Chemical and Biological Agents:
Typical performance against the gaseous agents specified in the NIOSH CBRN APR standard, chemical warfare agents and also for industrial agents TIC/TIMs is detailed below.
Note that the protection time is indicated for standard laboratory test conditions. THESE DO NOT NECESSARILY RELATE TO ACTUAL USE TIMES. Actual use times must be verified on the basis of a risk assessment of the likely hazards present in the intended use area. Threat Challenge Concentration (PPM) Protection Time (Minutes) Nerve Agent 87 >180 Hydrogen Cyanide 940 >100 Cyanogen Chloride 300 >80 Ammonia 2500 >20 Cyclohexane 2600 >30 Formaldehyde 500 >200 Hydrogen Sulfide 1000 >100 Nitrogen Dioxide 200 >20 Phosgene 250 >400 Phosphine 300 >375 Sulfur Dioxide 1500 >20 Industrial Agents TIC/TIMS a-Chloroacetophenone (CN) 16 >480 o-Chlorobenzylidene Malonitrile (CS) 3 >480 Hydrogen Sulfide 5000 >30 Hydrogen Fluoride 1000 >60 Hydrogen Chloride 5000 >30 Methylamine 5000 >20 Chlorine 5000 >20 The performance of the canister is, of course, dependent upon the actual concentration encountered. Protection against riot control agents exceeds NIOSH 42 CFR84 requirements for CS and CN. The filter canister can be changed under all operational conditions in 9 seconds.
Breathing resistance 45mm of H2 O @ 85 l/min (typical)
A unique standard humidity indicator is located on the top of the CBRNCF50 filter and visually displays performance degradation due to moisture uptake over time. The indicator turns white to blue signaling that the unit pack was compromised and the filter must be discarded.
The materials used and the method of construction of the filter canister have been designed to meet operation and storage requirements in accordance with NIOSH CBRN criteria. When stored in its original packaging the filter canister retains its operational effectiveness and efficiency under the following environmental storage conditions:
Operational Temperature -32°C to 71°C
The filters have been exposed to high and low ambient storage temperatures without harmful effects.
Humidity range 5% to 100% RH
The filters have been tested following storage in high humidity environments and have been found to be effective.
The filter will retain its effectiveness in heavy rainfall conditions and it is not prone to water ingress.
The filter will not deteriorate with exposure to salt breezes for 24 hours.
Sand and Dust
The filter will not deteriorate when exposed to 24 hours of wind driven sand and dust conditions.
Recommended Storage and Shelf Life
The predicted shelf life of the filter canister (sealed and packaged) is 5.5 years when stored between 14°F and 122°F (-10°C and 50°C) <80% RH.
