Abstract：The main component of gas in metallurgical enterprises is carbon monoxide and other gases. The main types of production safety accidents are poisoning, fire and explosion. It is an important safety measure to set up fixed gas alarm in the specific place, environment and post of the production site, and regulate the operators to carry portable gas alarm when they enter the gas area. Therefore, the performance parameters of gas alarm, including the standardized selection of measurement range, alarm value, response time and explosion-proof performance and the strengthening of detection and calibration, are the important basic work to prevent gas poisoning, fire and explosion accidents. Based on the current national safety standards and the current situation of the industry, the author analyzes the selection of performance parameters and puts forward specific suggestions.
