Hazardous property code
HP 13 Sensitising
Waste that contains substances that can cause allergic reactions, affecting the skin or respiratory system.
HP 13 covers waste containing substances that can cause sensitisation — an allergic response affecting the skin or the respiratory system, which may appear only on later exposures rather than the first.
It is recorded on the consignment note as a hazard code, and assignment depends on the substances present and their concentrations in the particular consignment.
