Safety Control Standards
Essential guidelines for preventing fire, explosion, and safety hazards in storage tank areas through rigorous control of ignition sources, static electricity, ventilation, and monitoring systems.
1
Strict Control of Ignition Sources
- Open flames are strictly prohibited in the tank area
- Hot work operations must follow a strict approval process
- Thoroughly clear surrounding flammable materials before work begins
- Implement isolation and protection measures for all hot work
- All equipment entering the area must be explosion-proof
- Strengthen personnel management to prevent carrying of fire sources
- Prohibit wearing or removal of synthetic clothing to prevent static hazards
Prevents hazards caused by electrical sparks, static electricity, or open flames through comprehensive ignition source control.
2
Enhanced Static Electricity Control
- Storage tanks and related pipelines must have standardized static grounding devices
- Ensure grounding resistance meets standards to dissipate accumulated static electricity
- When using loading arms, ensure reliable connection between loading arm and tank
- Prevent static electricity generated by liquid impact during operations
- Control loading and unloading flow rates to avoid high friction
- Reduce risk of sparks from static buildup through proper flow management
Minimizes static electricity generation and accumulation through proper grounding and flow control measures.
3
Optimize Ventilation and Pressure Relief
- Storage tank area must have appropriate ventilation facilities
- Maintain air circulation to reduce gasoline vapor concentration
- Prevent vapor concentration from reaching explosion limits
- Install qualified safety valves and breather valves on tank tops
- Ensure timely pressure relief in case of abnormally high internal pressure
- Prevent tank rupture and leakage due to excessive pressure
- Regularly inspect ventilation and pressure relief equipment
Prevents equipment failure leading to risk accumulation through regular inspection and maintenance of ventilation systems.
4
Strengthen Monitoring and Early Warning
- Install gasoline vapor concentration monitoring devices
- Monitor vapor concentration in storage tank area and inside tanks in real time
- Issue early warning signals when concentration approaches critical value
- Assign dedicated personnel to conduct regular inspections
- Check tank body, valves, pipelines, etc., for leaks
- Promptly address any identified potential hazards
- Establish comprehensive emergency response mechanism
- Equip sufficient fire-fighting equipment and emergency supplies
Ensures rapid and effective handling of emergencies to prevent accidents from escalating through proactive monitoring and preparedness.
