Effectiveness of Gas Fired Water Heater Elevation in the Reduction of Ignition of Vapors from Flammable Liquid Spills

摘要

Elevating ignition sources to protect against the ignition of vapors from flammable liquid spills has a long history in the national standards and codes. Accident data from the Consumer Product Safety Commission and the National Fire Protection Association identify gas tired water heaters as the major ignition source of flammable liquid vapor accidents in the home. During the past ten years, numerous different laboratories have conducted tests to evaluate the effectiveness of elevating gas fired water heaters to prevent the ignition of flammable liquid vapors. Analysis of the results of 48 tests from three laboratories demonstrate the effectiveness of elevating gas fired water heaters in reducing the ignition of flammable liquid vapors in the home.
