Aboveground storage tanks (ASTs) play an important role in storing flammable and combustible liquids such as gasoline, diesel, and industrial chemicals. However, although they play a critical role in industrial operations, they can also pose significant fire hazards if not properly managed. Fires involving ASTs can cause severe property damage, environmental contamination, and even loss of life. This is why best practices for AST fire prevention and hazard control are often incorporated into comprehensive environmental consulting services. If your business handles sensitive liquids, as mentioned earlier, your company should implement strict fire prevention and hazard control measures.
Best Practices for AST Fire Prevention and Hazard Control
The occurrence of AST fires can be due to several factors, such as equipment failure, static electricity, improper handling of flammable liquids, and exposure to heat sources or open flames. Overfilling tanks, corrosion, and leaks should be avoided because they create a highly combustible environment. The first steps towards effective fire prevention are understanding these risks.
Regular Inspections and Maintenance
Establish routine inspection and maintenance schedules, as they are the cornerstone of AST Fire Prevention. A regular schedule should be set for inspection of tanks, piping, valves, and associated equipment. Look for signs of corrosion, cracks, leaks, and structural damage. An inspection of the tank’s grounding and bonding systems is also crucial, as they help prevent static electricity buildup, which is a common ignition source for flammable liquids.
Maintenance goes beyond just structural checks. Filters, pressure relief valves, and emergency shutoff systems should be tested periodically to make sure they are functioning properly. Prompt correction of defects is crucial to prevent hazards from escalating.
Implement Proper Tank Design and Installation
Fire prevention requires proper tank design and installation. ASTs should be made of fire-resistant materials and placed in areas with sufficient space to prevent fire spread. Consider environmental conditions such as wind, temperature, and proximity to ignition sources. Bund walls or dikes can serve as secondary containment systems to help contain spills and reduce the risk of fire spreading.
Proper venting and overflow protection are also essential. Pressure buildup can lead to leaks or explosions, but venting systems can prevent this. In the same way, overflow protection systems minimize the risk of liquid escaping or igniting.
Control of Ignition Sources
Another crucial aspect is hazard control. Potential ignition sources near AST’s should be minimized. Strictly prohibit smoking, welding, grinding, or the use of electrical equipment near flammable liquids. Post warning signs and install physical barriers to ensure these restrictions or prohibitions are enforced. Lightning protection systems should also be installed for tanks that are in storm-prone areas.
Implement Fire Suppression Systems
It is important to understand that, despite preventive measures, fires can still occur. This underlines the importance of having appropriate fire suppression systems. Foam-based suppression systems are particularly effective for liquid fires because they help smother flames and prevent vapor release. Portable fire extinguishers are a great help, especially when placed in strategic locations around the tank area and personnel are well-trained in their use.
Emergency Preparedness Training
AST fire prevention and hazard control includes employee training. Staff familiarity with fire hazards, emergency shutdown procedures, and evacuation routes is essential. Fire drills should be conducted regularly to ensure employees can respond quickly and effectively during emergencies.
The development of a comprehensive emergency response plan tailored to AST operations is a crucial addition to emergency preparedness. This plan includes coordination with local fire departments, spill containment strategies, and protocols for notifying regulatory authorities.
Monitoring and Documentation
Ongoing monitoring and documentation are also needed for effective hazard control. Maintain records of inspections, maintenance, employee training, and any incidents. Make them as detailed as possible.
