THE METHOD OF DETECTION FOR DANGEROUS GAS LEAKAGE

摘要

The present invention relates to a method for detecting a hazardous gas leak, which is configured of a tape or a patch coated with substances changing its color while reacting with the component of all kinds of gases. More particularly, the gas detecting tape and the patch is manufactured by reforming detecting agents, which changes the color while reacting with the gas, to substance in powder state or sheet state, which then is attached on the tape or the patch. The tape could be attached to a joint portion of a gas tube, where a gas leak might be generated and in case of the patch, sealed places such as inside the building or the car using a gas as a fuel. If the hazardous gas leaks, the detecting agent will react with the gas and change the color, so an accident occurred by the gas could be previously prevented.
