HP Code



Waste which on application can cause skin irritation or damage to the eye. Hazards HP 4 and HP 8 are linked because they refer to the potential for harm or damage to tissue at different levels of severity. Hazardous wastes containing irritant substances will only display irritant properties. Hazardous wastes containing corrosive substances can display either corrosive or irritant properties dependent upon concentration. The mechanical irritation produced by some substances, for example mineral wool, is not included within the definition of HP 4
