How can I test waste for Hazard HP3 classification?

The government guidelines on waste assessment and classification outline different hazards which wastes may be
classified as, to assist in safely handling them.

If waste contains hazardous components, or has hazardous properties, it may be classified according to a hazardous property assessment.

We have taken a look at the requirements of hazardous property assessment for HP3 – flammable wastes.GHS-02

How do I know if waste is classified as flammable?

The government technical guidance WM3 document fully outlines how to assess and classify your waste. Step 6, on page 11, details what must be done to assess the hazardous properties of waste.

This explains there are 3 possible methods to classifying waste;

  1. Consulting the safety data sheet
  2. Calculation
  3. Testing

Of course using the safety data sheet or calculating the flammable properties or flash point is only possible if you know in detail the composition of the waste, or know for sure what contaminants are present.

In many cases the full composition is unknown, so testing must be carried out instead.

 

Part C3 of Appendix C, on page 105 here, details how to assess waste for HP3 classificaiton. As seen in the decision tree for conducting the assessment, testing the flash point is the first step in assessing liquid waste, or wastes that have a freely draining liquid phase.

This assessment must be performed in accordance with the European Chemical Agency’s (ECHA) guidance on the application of CLP criteria. These guidelines state (on page 41 here) the acceptable test methods which can be used to test the waste.

Please note that all flash point testers generally require a gas supply for the pilot flame, and the safety considerations of performing the test should be considered and evaluated before testing is done.
