Lefilter Pyrolysis Plant Core Contents

The emergency management standards for pyrolysis oil refineries are formulated around the whole process of accident prevention, emergency response and post-incident disposal, and must be integrated with process characteristics. The core contents are as follows:

Standards for Compiling Emergency Plant

Full coverage of special plans

Special emergency plans must be formulated for high-risk scenarios in the plant, including: Fire and explosion emergency plans (for reactors, tank farms and gas pipelines)

Toxic and harmful gas leakage emergency plans (for hydrogen chloride and VOCs)

High-temperature scald and mechanical injury emergency plant. Environmental emergency plans (for hazardous waste leakage and exhaust gas exceeding standards)

Standards for Implementing Emergency Drills

Drill frequency

Comprehensive emergency drills shall be conducted at least once a year; special emergency drills (e.g., gas leakage handling, fire fighting) shall be conducted at least once every six months.

Targeted drills shall be additionally organized for new employees before taking up their posts and after equipment modification.

List of Core Emergency Supplies

Fire-fighting Supplies

Dry powder fire extinguishers, carbon dioxide fire extinguishers, fire hoses, fire sand, fire blankets. They shall be allocated according to the density requirements of risk areas (one fire extinguisher per 50 ㎡ around reactors).

Gas Leakage Control Supplies

Gas masks (filter type/isolating type), portable gas detectors (for oxygen content, hydrogen chloride and combustible gas concentration testing), chemical protective suits, leak-stopping tools (wooden wedges, leak-stopping adhesives).

First-aid Supplies

Emergency shower devices, eyewash stations (to be installed within 15 meters of the operation area), first-aid kits (containing burn ointment, tourniquets, oxygen cylinders), stretchers.

Supplies Management Requirements

Emergency supplies shall be stored at fixed locations, managed by designated personnel and marked with obvious signs.

The integrity of supplies (e.g., pressure of fire extinguishers, power of detectors) shall be inspected monthly; invalid supplies shall be replaced in a timely manner.

Standards for Emergency Response and Disposal

Alarm and Reporting Specifications

After an accident occurs, on-site personnel must press the emergency alarm button immediately and report to the team leader/commander-in-chief. For major accidents, a report shall be submitted to the local emergency management department and ecological environment department within 1 hour. Concealment, false reporting or delayed reporting is prohibited.

Personnel Evacuation Standards

Evacuation routes and assembly points (far away from hazard sources and located in the upwind direction) shall be clearly defined. Personnel must wear personal protective equipment during evacuation.

A warning zone shall be set up to prohibit unauthorized personnel from entering. The scope of the warning zone shall be determined according to the diffusion radius of leaked gas or the affected area of fire.

Safety Requirements for Emergency Rescue Operations

Rescuers must hold valid certificates and wear protective equipment such as chemical protective suits and gas masks.

Before entering confined spaces such as reactors, gas detection shall be conducted and the lockout-tagout (LOTO) system shall be implemented, with designated personnel monitoring outside.

Standards for Post-incident Disposal and Recovery

Accident Investigation and Analysis

After accident disposal, professional personnel shall be organized to investigate the cause of the accident, clarify responsibilities and form an accident investigation report. Rectification measures shall be formulated for potential hazards to prevent the recurrence of similar accidents.

On-site Recovery Specifications

Pollutants at the accident site (e.g., leaked oil, carbon black) shall be treated harmlessly; damaged equipment shall be inspected and repaired.

Production can only be resumed after passing the safety assessment.
