Industry background:

In recent years, various safety accidents in the chemical and hazardous chemicals industries have occurred frequently, causing a large number of casualties and property losses. The accidents involved mainly include gas leakage poisoning and suffocation, chemical explosions, physical explosions and fire accidents. The dangers and hazards of flammable and explosive gases and toxic gases are common in the energy and chemical industry. This phenomenon is determined by the inherent characteristics of the industry itself. Most chemical companies handle a large number of raw materials, intermediates and products that are flammable, explosive and toxic in nature; many of the chemical production, storage and transportation processes are in abnormal conditions such as heating (or low temperature), pressurization (or negative pressure), catalysis, chemical reactions, etc., and are prone to volatilization of flammable, explosive and toxic gases. Therefore, explosion-proof and anti-toxic gas has a special and important position in energy and chemical safety.
