The Plumber's Choice 3 in. x 11.5 in. Yellow Exhaust Gas Safety Decal

This Exhaust decal conforms to the ANSI-ASME requirements and Massachusetts Gas Vent Sign Regulations. Since gas vents require constant maintenance, care and repair, it is of utmost importance that they be marked clearly and precisely. This sign can be used to identify the Exhaust ducts for any of your commercial or residential installations (e.g. sprinkler system, ventilation system, water heater).
