Safety Information for the Semi-Water Gas Holder Storage Area (Gas Holders): The semi-water gas holder has a volume of 00,000 m3, with an operating pressure of 300 mmH2O; its main contents are CO, CO2, H2, and N2. It falls under the jurisdiction of the gas generation workshop. Primary responsible person: ---- Person in charge: ---- Hazard level: The explosion limit of hydrogen is 4–75.6%, while that of carbon monoxide is 12.5–74%. The risk associated with the target is leakage. High concentrations of CO can cause poisoning in humans, and it burns easily when exposed to high temperatures. When the leaked gas reaches its limit, it can explode easily in the presence of an open flame; in enclosed areas, an excessive oxygen concentration can generate enough energy to cause a severe explosion. Emergency rescue plan: 1. Handling of material leakage incidents. In the event of a leak, on-site personnel should promptly report it to the supervisor or those in the control room, wear appropriate protective equipment, locate the source of the leak, seal it, and improve ventilation at the affected area. 2. Ordinary fire: Cut off the gas supply; if necessary, stop operations. Organize personnel to wear fire and poison protection gear to extinguish the fire. Fire extinguishers available include foam extinguishers, dry powder extinguishers, and water. 3. Explosion incident: Personnel should evacuate the site to the upwind side. Those on site should take emergency measures and report to the relevant personnel and departments, promptly cutting off the gas and power supplies to prevent the incident from spreading. Operational precautions: Strictly control oxygen levels and keep away from sources of fire and heat. Keep the container properly sealed to prevent vacuum formation, and operators must strictly follow the operating procedures. Emergency phone: Production scheduling: 8003 (internal).
