GUIDE

Diesel Bladder Secondary Containment: Spill Berms and Safe Storage

A diesel bladder holds fuel; secondary containment holds the fuel if the bladder ever leaks. For mining camps and remote sites, containment is not optional equipment — it is part of the storage system, and many sites and regulators require it.

WHAT IT IS

What secondary containment is

Secondary containment is a bund, berm or lined area around the bladder, sized to hold the fuel if the bladder fails. It also catches drips during filling and emptying. Exact bund capacity rules differ by site and country — confirm the local requirements for your project.

GROUNDING AND VENTING

Grounding and venting

Fuel bladders commonly use an antistatic inner layer and a grounding or earthing point, plus a vent valve. The supplier's exact valve, vent/flame-trap and antistatic specification is confirmed per order — never assume it.
