Provide emergency pressure venting in the event of a fire to avoid drum failure and catastrophic consequences. All safety drum vents automatically relieve pressure between 3 and 8 psi 30 to 55kPa and include a flame arrester to absorb and safely dissipate heat. Valve within the vent is tested to allow 61 cubic inch 1-L of water through a 3/8-in 9.5-mm pipe nipple in less than 6 seconds for vacuum relief during drum dispensing operations. Vacuum relief permits smooth liquid flow and prevents possible drum collapse and leakage. Vacuum relief is automatic on vertically-installed vents and manual on horizontally-installed vents. Safety fill vents and funnels fit the 2-in 51-mm bung on a vertically-stored drum. The brass vent provides automatic pressure and vacuum relief and includes a brass cap with safety chain tethered to the vent to prevent misplacement or loss. Remove cap during drum filling operations. Model no. 08211 includes a 9-in229-mm wide polyethylene funnel to facilitate solvent waste disposal and reduce spillage. Keep vent capped in closed position after filling operations to prevent flammable vapor from escaping. Six-inch 152-mm flame arrester safely dissipates heat and prevents flashback from external ignition sources.
