THE PURPOSE OF A FIREWALL TRUCK: The ANTHONY Firewall Series is designed to restrict a flame generated from (1) acetylene or other welding fuel-gas cylinder placed adjacent to (1) oxygen cylinder on the same truck. The center baffle partition performs this function. The purpose of the center partition is to restrict a flame generated by the acetylene or other welding grade fuel-gas cylinder from heating the adjacent oxygen cylinder contents to such an extent that it causes expansion of the oxygen cylinder contents, which increases the PSI level higher than the D.O.T. prescribed safe pressure level. Should the oxygen cylinder contents be expanded beyond the D.O.T. safe level, the expanded contents could activate the safety control burst disc, which would then allow oxygen to be added to the fuel-gas cylinder generated flame, causing a more intense or expanded flame.
HOW ANTHONY BUILDS IT’S FIREWALLS: Current Federal OSHA interpretations regarding firewall regulations state that a single 1/4″ steel plate is insufficient as a firewall, because it cannot protect the cylinder from excessive radiant heat emanating through the 1/4″steel plate for 30 minutes. Anthony agrees with the OSHA assessment of a firewall. For this reason, ANTHONY developed the Triple Baffle Firewall Partition comprised of (3) separate baffles which create (2) exhaust vents at the top, and (2) intakes at the bottom. This allows the heat generated from the welding grade fuel-gas flame of(1) cylinder to draw ambient air in from below^ which drives the heated air up through the top vents. Thus, the heat transfer to the oxygen cylinder on an ANTHONY firewall cart, is minimal, because the baffle design directs the heat upward. This substantially reduces the probability that heat from the acetylene or other welding grade fuel-gas will radiate through the steel firewall baffle plates such that it reaches the oxygen cylinder and raises the oxygen contents above the D.O.T. safety level.
