Install whipchecks on equipment

Preventing injuries should be the top priority on every job site

Customers have asked why they should install whipchecks on their blast equipment.

If a blast hose, bull hose or any other hose connection points become detached, and you're in close proximity, sustained injury could result in death.

Flailing from a detached bull hose at 100 psi can kill.

Whipchecks are a mandatory requirement indicative to a safety standard. Even a 1 inch airline supplying air to your Radex breathing airline filter must have a whipcheck.

By fitting whipchecks to your equipment, especially the stocking variety, the situation becomes much less volatile as the couplings movements are more restricted. This gives much more time for the operator to shut down the air supply when the connection fails.

There are four locations where whipchecks must be installed

  • From the air compressor to the bull hose
  • On the inlet to the blast machine
  • On the inlet and outlet connections
  • Connection points along the hose

And remember: always apply two lock pins on a bull hose coupling.

To correctly install a whipcheck it must be fully extended and flat along the hose. Any slack and the whipcheck will leave opportunity for accidents to occur.


Watch the video showing the dangers when hose blows off a coupling at high pressure.
