What is in it, and does it need a COSHH assessment?

Type what is on site — a substance, a product, or a dust the work makes — and read what the published lists say about it: the hazards, the symbols on the label, the workplace exposure limit where there is one, and whether a COSHH assessment normally covers it.

Searches 4,430 classified substances, all 426 exposure limits and 50 site-language entries with their trade names. Nothing you look up is saved.

A COSHH assessment normally covers this.

  • The classification list gives it 4 health hazard statements — H350, H340, H372, H304.

  • health hazardGHS08
Hazard statements

  • May cause cancer. (H350)

  • May cause genetic defects. (H340)

  • Causes damage to organs through prolonged or repeated exposure (central nervous system). (H372)

  • May be fatal if swallowed and enters airways. (H304)

Note P applies: The mandatory classification as a carcinogen or mutagen applies unless it can be shown that the substance contains less than 0.1% w/w benzene (Einecs No 200-753-7), in which case a classification in accordance with Title II of this Regulation shall be performed also for those hazard classes. Where the substance is not classified as a carcinogen or mutagen, at least the precautionary statements (P102-)P260-P262-P301 + P310-P331 shall apply.

Brush cleaner and thinner for oil-based paints. The MCL entry is for the petroleum naphtha family and carries Note P — the carcinogen and mutagen classification applies only where benzene content is 0.1% or more, which is why a retail tin is not labelled that way. EH40 gives white spirit no single exposure limit; suppliers derive one for their own blend.

Questions people ask

What is a COSHH assessment for?
It records what hazardous substances a job involves, who could be exposed and how, and what is being done to control that exposure. The regulations require the assessment before the work starts, and require it to be reviewed when the work or the substance changes.
What is a workplace exposure limit?
A concentration in the air, averaged over a reference period, that must not be exceeded — 8 hours for a long-term limit, 15 minutes for a short-term one. They are approved by HSE and published in EH40/2005. This page shows them in full, straight from the published table.
Does every substance need an assessment?
No. The regulations bite on substances hazardous to health — those with health hazard classifications, those with an exposure limit, dusts and fumes generated by the work, and biological agents. This tool tells you which of those apply to what you searched, and shows the evidence it used.
Why is asbestos not covered here?
Asbestos and lead are excluded from COSHH because they have their own regulations — the Control of Asbestos Regulations 2012 and the Control of Lead at Work Regulations 2002. Search for either and this tool says so rather than giving you a COSHH answer.
Where can I read more about COSHH?
The free guides cover what COSHH is, how an assessment works, what the nine hazard symbols mean, and how to read a safety data sheet — in plain trade language, with every regulation named and linked.
The product on site is a brand name, not a chemical. What then?
Search the brand name — many are recognised. Where a product is a mixture, its hazards belong to its own formulation, so the supplier's safety data sheet is the document that decides. This tool will say so, and show what that kind of product typically carries.
