Frequently Asked Questions

Hydrostatic testing pressure-tests an extinguisher cylinder with water to confirm the shell can safely contain its charge without leaking or deforming.

Dry-chemical extinguisher cylinders require hydrostatic testing every 12 years; other agent types test on shorter intervals.

The extinguisher is emptied and depressurized, the cylinder is filled with water and pressurized to the test level, then checked for expansion, leaks, or distortion before the result is recorded.

A cylinder that fails is removed from service and replaced, since it can no longer safely hold its charge.

No, hydrostatic testing is a pickup and return, shop-based test, since it requires specialized equipment to pressure-test the cylinder.

A passing cylinder is stamped with the test date and receives a new tag before being recharged and returned to service.

Dry-chemical cylinders are on the 12-year interval; other extinguisher types such as CO2, water, and wet chemical test on shorter cycles.

Hydrostatic testing intervals are set by NFPA 10.

Yes. Since testing happens off-site, the unit is out of service during transport and testing, so many facilities arrange a replacement unit to stay covered.

Hydrostatic testing pickup and return service is provided throughout Southeast Idaho.
