What fire protection measures and standards are required for compressor rooms?

Fire Risk Analysis of the Compressor Room

During operation, air compressors generate high temperatures and contain lubricating oil internally. Poor heat dissipation, lubricant leakage, or aging electrical wiring can easily lead to fires or even explosions. Therefore, fire‑proof design and management of compressor rooms are of paramount importance for industrial safety.

Fire Safety Requirements for Buildings and Layouts

The architectural structure and spatial layout of the air compressor room must comply with relevant national fire safety technical standards to control the risk of fire spread at its source.

• Fire resistance rating:The fire-resistance rating of the air compressor room shall generally not be lower than Grade II, and its walls, roof, and columns must be constructed from non-combustible materials.
• Fire separation:If the air compressor room is adjacent to other production areas, it must be strictly fire-separated using firewalls and Class A fire doors.
• Safe Evacuation:The computer room shall be equipped with at least two emergency exits, and the doors must open in the direction of egress to ensure that personnel can evacuate quickly in an emergency.

Fire Protection Facilities and Equipment Configuration

Well‑designed fire‑protection systems are essential for extinguishing incipient fires and containing emergencies. The air compressor room should be equipped with appropriate fire‑fighting equipment, tailored to its floor area and the capacity of its installed equipment.

• Fire extinguisher configuration:Sufficient dry powder or carbon dioxide fire extinguishers shall be provided and placed in conspicuous, easily accessible locations.
• Automatic fire suppression system:For large or critical air compressor rooms, it is recommended to install a gaseous fire suppression system or an automatic sprinkler system to enable automatic fire suppression during unattended operation.
• Fire alarm system:Smoke and heat detectors must be installed and linked to the fire control room to ensure that fires are detected at the earliest possible moment.

Electrical Fire Protection and Ventilation/Heat Dissipation Design

Electrical faults and the accumulation of high temperatures are the primary causes of fires in air compressor rooms; sound electrical design and an effective ventilation system can significantly mitigate these risks.

• Electrical Circuit Protection:All cables shall be protected by conduit to prevent exposure. Electrical equipment must be equipped with overload, short-circuit, and leakage‑current protection.
• Explosion Protection and Grounding:Lighting and electrical equipment in the computer room shall comply with dust‑proof and explosion‑proof requirements, and all metal equipment and piping must be properly grounded to prevent static electricity.
• Forced ventilation system:The computer room shall maintain adequate natural ventilation and be equipped with forced exhaust systems to ensure that the indoor temperature does not exceed the equipment’s maximum allowable operating temperature, thereby preventing high‑temperature volatilization of lubricating oils.

Daily Fire Safety Management and Emergency Response Plan

Hardware facilities can achieve their full potential only when supported by a rigorous management system. Enterprises should establish and refine a comprehensive fire safety management system for their compressed-air compressor rooms.

• Regular Inspections:Assign dedicated personnel to conduct daily inspections of the oil level, oil temperature, exhaust gas temperature, and electrical wiring, and promptly clean up oil stains and combustible debris in the machine room.
• Equipment Maintenance:Regularly replace the lubricating oil, oil filter element, and air filter element to prevent high-temperature self‑ignition caused by oil degradation or excessive contaminants.
• Emergency Drill:Develop targeted fire emergency response plans, and regularly conduct fire safety training and firefighting drills for operational personnel to enhance their ability to extinguish incipient fires.
