Understanding Flame Arrestors: A Guide to Evaluating for Chemical Storage Tanks

Flame arrestors are important safety devices that prevent the spread of flames or explosions in chemical storage tanks, which are extremely hazardous environments. Whether you are a facility manager or a safety professional, it is important to know how to evaluate flame arrestors for chemical storage tanks to ensure the highest level of safety in your facility.

What is a Flame Arrestor?

Simply put, a flame arrestor is a safety device that prevents the spread of flames or sparks from a fire or explosion into a storage tank. It consists of a grid or array of closely spaced metal plates that allow flammable vapors to pass through while extinguishing flames. The size, shape, and construction of the flame arrestor determine its effectiveness in preventing the spread of fire.

Factors to Consider When Evaluating Flame Arrestors

• Tank Type and Size: Make sure that the flame arrestor is specifically designed and selected for the type and size of tank in which it will be installed. This is particularly important as the use of an inappropriate flame arrestor can have serious consequences, such as failure or inadequate protection.
• Chemical Stored: Different chemicals have different degrees of flammability and reactivity, which can affect the type of flame arrestor required. For example, a flammable chemical will require a different type of flame arrestor than a less flammable chemical.
• Ambient Conditions: The selection and performance of the flame arrestor can be affected by the operating temperature, pressure, and the potential presence of corrosive or abrasive materials in the tank.

Maintenance of Flame Arrestors

Regular inspection and maintenance are essential to ensure the continued effectiveness of the flame arrestor. This involves cleaning the unit to remove any residue or build-up, and replacing the flame arrestor if it becomes damaged or corroded.

Summary

Flame arrestors play a key role in ensuring the safety of chemical storage tanks. To properly evaluate flame arrestors for chemical storage tanks, factors such as the size and type of tank, the chemicals stored, and the ambient conditions must be considered. Regular maintenance and proper selection and installation of the flame arrestor are also critical to providing adequate protection against potential fires and explosions.
