New COSHH Assessments Required After New EU Directive Significantly Reduces 31 Exposure Limits
Businesses will need to review their COSHH Assessments after a new Directive from the EU significantly reduced exposure limits for 31 chemicals in a bid to boost worker health.
Six of the chemicals have had their exposure levels halved, while 14 others have had an exposure level set where none had previously in place.
It means businesses handling these chemicals will need to review their COSHH Assessments to ensure their people are not put at risk – and the business is compliant – under this new regime.
The Directive is effective from 21 August 2018, so if you are affected you should be acting now to reduce your business risk.
Here’s the full list of chemicals affected by the Directive
- Manganese and inorganic manganese compounds (as manganese)
- Glycerol trinitrate
- Carbon tetrachloride; Tetrachloromethane
- Acetic acid
- Hydrogen cyanide (as cyanide)
- Methylene chloride; Dichloromethane
- Vinylidene chloride; 1,1-Dichloroethylene
- Tetraethyl orthosilicate
- Acrylic acid; Prop-2-enoic acid
- Bisphenol A; 4,4′-Isopropylidenediphenol
- Diphenyl ether
- 1,4-Dichlorobenzene; p-Dichlorobenzene
- Acrolein; Acrylaldehyde; Prop-2-enal
- Methyl formate
- Ethyl acetate
- Sodium cyanide (as cyanide)
- Potassium cyanide (as cyanide)
- Diacetyl; Butanedione
- Carbon monoxide
- Calcium dihydroxide
- Calcium oxide
- Sulphur dioxide
- Lithium hydride
- Nitrogen monoxide
- Nitrogen dioxide
- Terphenyl, hydrogenated
Remember COSHH assessments should ensure exposure is below these Workplace Exposure limits. The limits are seen as a maximum allowable exposure level, and if you can reduce exposure to a lower level then this should be considered.
When reviewing your COSHH Assessments ensure that you choose control measure that are relevant from the COSHH Hierarchy of Controls, with ‘1’ being a more suitable control measure and ‘7’ – the use of personal protective equipment (PPE) – being the last consideration.
COSHH Hierarchy of Controls
- Eliminate the use of a harmful product or substance and use a safer one
- Use a safer form of the product, eg paste rather than powder
- Change the process to emit less of the substance
- Enclose the process so that the product does not escape
- Extract emissions of the substance near the source
- Have as few workers in harm’s way as possible
- Provide personal protective equipment (PPE) such as gloves, coveralls and a respirator. PPE must fit the wearer

How the Directive will be represented in the UK regulatory framework
HSE publication ‘EH40/2005 Workplace exposure limits’ records the recommended Workplace Exposure Limits for several hundred substances.
Last updated in 2011, this is likely to be revised to reflect the values now stated in the EU Directive.
