Tamper Proof
NOTE: CO2 fire extinguisher hoses have a continuous metallic braid that connects to both couplings to minimize the static shock hazard from the discharging gas. An annual electrical conductivity test is required to verify that the hose is conductive from the inlet coupling to the outlet orifice. CO2 hose assemblies that pass the conductivity test should have the test information recorded on a label that is attached to the hose.
