6.1.5 What is not a substance hazardous to health under COSHH? COSHH applies to virtually all substances hazardous to health except:
(1) asbestos and lead, which have their own regulations;
(2) substances which are hazardous only because they are:
• Radioactive:
• At high pressure;
• At extreme temperatures; or
• Have explosive or flammable properties (other regulations apply to these risks);
(3) Biological agents that are outside the employer’s control, e.g. catching an infection from a workmate.
