CQC inspectors look for a COSHH register, assessments for the products in use, locked storage that residents cannot reach, and evidence that staff have been trained. The assessment for each product should say where it is stored and how residents are kept away from it.
Alcohol hand sanitiser is easy to overlook. Large quantities are a fire hazard, and it dries and cracks the skin with repeated use, which is a COSHH issue in its own right. Skin checks for staff who use it constantly are a reasonable control.
Biological agents such as norovirus and C. difficile are hazardous substances under COSHH too. The assessment for cleaning a room after an outbreak is different from routine cleaning and should say so.
