Common Questions About this Risk Assessment
This Chemical Risk Assessment provides the substance-level hazard inputs needed for a COSHH assessment under the UK Control of Substances Hazardous to Health Regulations 2002. It is not a substitute for a full workplace risk assessment. You must combine this with your own assessment of how the substance is actually used on your site, including task specifics, exposure duration and local controls.
The CRA is derived from the hazard data in the manufacturer's SDS for Potassium Dichromate, mapped against standard workplace task profiles. It is updated in line with SDS revisions. The CRA is a starting point for your own assessment, not a finished document.
A Safety Data Sheet is produced by the manufacturer and describes the hazards of the substance itself. A Chemical Risk Assessment evaluates those hazards in the context of how the substance is actually used in the workplace, covering specific tasks, exposure routes and recommended controls. Both documents work together.
Yes, a free ISDSS account gives you access to both the SDS and the linked CRA for over 1.5 million substances. Registration takes under two minutes.
