Choose the correct statements about classifying physical hazards for mixtures or complex substances (tick all which apply)

Most physical hazards must be classified from first principles

You can rule out some physical hazard tests for mixtures on the basis of chemistry

Physical hazards of mixtures can always be calculated based on components

It’s easier and more accurate to have a flash point determined than to use the calculation method
