Why DOP Testing Your H-Class Vacuum Matters

(and where to get it done on the Gold Coast, Brisbane & Northern Rivers)

If you’re running an H-Class vacuum or dust extractor, you already know it’s not just another piece of kit—it’s your frontline defence against hazardous dust on site. But owning the machine isn’t enough. To stay compliant (and safe), your vacuum needs regular DOP testing and certification.

Here’s what contractors across the Gold Coast, Brisbane and the Northern Rivers need to know:

What is DOP Testing?

DOP (Dispersed Oil Particulate) testing is the industry standard method for checking the integrity of your H-Class vacuum. It ensures the HEPA filters are performing at 99.995% efficiency—exactly what’s required to keep harmful silica and asbestos dust out of your lungs. Without it, even the best vac on the market can’t be trusted to do its job.

How Often Should You Test?

Australian regulations require initial DOP testing on new units, and then routine testing at least every 12 months (more frequently if the machine is heavily used). Think of it like servicing your ute—you wouldn’t skip it and risk a breakdown. Same goes for your vac.

What Happens if You Don’t?

Skipping DOP testing leaves you exposed on two fronts:

  • Safety risk: You and your crew could be breathing in fine dust without realising.
  • Compliance risk: WorkSafe inspectors can and do check for certification. Fines and shutdowns aren’t worth the gamble.
