Explosives and Munitions Flooring
4145.26 and NFPA99 Approved Munitions Flooring
There are many industries that handle materials, which under the right conditions, can ignite, causing a fire or explosive event. These areas require 4145.26 or NFPA99 approved epoxy flooring. Flammable storage or processing areas, munitions, or even handling of combustible bulk solids. Conductive flooring is the one thing that ties together all the surfaces electrically, in a processing or storage area.
Dangerously high charges can lead to ignition hazards caused by static charges during industrial processing. A dangerous event can occur when two situations exist at the same time. This includes both a dangerously high charge, and a potentially explosive atmosphere. In contrast, these conditions can occur during the handling of non conductive, combustible liquids such as non conductive, combustible bulk solids, or hydrocarbons. Sometimes even conductive materials can accumulate dangerously high charges if they are being processed in non conductive equipment.
Electrical Standards – Munitions, Ordnance & Flammable Area Floors
Electrical resistance standards required for a grounded conductive floor, for most munitions, explosives, and flammables processing areas;
The maximum resistance of a body, plus the resistance of the conductive shoes, plus the resistance of the conductive floor to the ground system shall not exceed 1 million ohms total.
R1 (body) + R2 (shoes) + R3 to ground (Floor ) < 1,000,000 ohms
Floor Resistance Example:
If the floor’s resistance to ground is 250,000 ohms then the sum of the resistance of the body plus the resistance of the shoes must be below 750,000 ohms or the total allowable resistance limit of 1 Million ohms would be exceeded.
EPF provides grounding, testing and certification, to meet the following compliance standards.DOD 4145.26M
Examples of Ignition and Fire Hazards
Examples of fires and explosions caused by static electricity as ignition source range from the filling of a plastic bucket with toluene to the pneumatic filling of a large storage silo with a combustible bulk solid. Accidents also occur during the filling of solvent-moist products into dryers, the emptying of centrifuges,
and the dumping of combustible bulk solids out of flexible intermediate bulk containers (FIBCs).
These systems are designed as hazardous area floor protection, and explosion proof flooring. Our 4145.26M and NFPA99 certified flooring provide maximum protection and peace of mind in hazardous storage and processing areas.
