When Is Grounding Flammable Cabinets Necessary?
Dispensing Flammable Liquids and Static Electricity Risks
You face real risks when you handle flammable liquids. The flow of these liquids can create static electricity. This static can build up whether you use a pump or pour the liquid. If you do not control this, a spark can jump and cause a dangerous ignition of vapors. You must bond and ground metal containers to prevent this hazard. When you transfer flammable liquids from large containers, static electricity can build up quickly. You should always attach a metal bonding strap or wire between the bulk container and the receiving vessel. Grounding one of the containers helps direct any static charge safely to the ground. This step prevents electrostatic discharge and reduces the chance of explosions.
Note: The Barton Solvents explosion in Des Moines happened because workers did not ground equipment during liquid dispensing. Static electricity caused a spark, which led to a fire and destroyed the warehouse.
Facility-Specific Scenarios for Grounding
You need to look at your facility’s processes. Grounding flammable storage cabinets is essential for safety, especially during dispensing and collection. If your facility handles flammable materials often, you face a higher risk of static discharge. You should ground cabinets to prevent accidents and explosions. Internal cabinet grounding becomes important when you store or move flammable materials near sources of static electricity. You must also consider the type of flammable liquids you use and the size of your containers. Each facility has unique risks, so you should always review your safety needs.
- Grounding is critical during dispensing and collection.
- Facilities with frequent handling of flammable materials need extra care.
- Internal cabinet grounding helps reduce static buildup.
Best Practices for Flammable Storage Cabinets
