Regulations and safety
There is no licence to buy methanol in the UK. There is a stack of duties that land on you the moment it arrives — and one that catches almost everyone who takes bulk deliveries.
- UN number
- UN 1230
- ADR
- Class 3 (6.1), PG II
- Flash point
- ~11 °C
- WEL, 8-hr TWA
- 200 ppm (Sk)
- Small-load limit
- 333 L
There is no general licence to buy methanol in the UK. It is not a regulated poison under the Poisons Act 1972 and it is not a regulated explosives precursor. What exists instead is a stack of duties that land on the receiving site the moment the material crosses the gate — and a supplier who does not raise them is a supplier doing you no favours.
Two properties drive almost all of it. Methanol has a flash point around 11 °C, which means it gives off an ignitable vapour at ordinary British room temperature and burns with a flame that is nearly invisible in daylight. And it is acutely toxic by ingestion, inhalation and skin absorption, which is why the workplace exposure limit carries a skin notation. Neither property alone is unusual. Together they justify the extra caution.
Key points
- No purchase licence applies, but COSHH, DSEAR and the carriage regulations all do.
- The UK workplace exposure limit is 200 ppm over 8 hours and 250 ppm short-term, with an Sk skin notation — glove selection matters as much as ventilation.
- The Dangerous Goods Safety Adviser duty falls on anyone who consigns, carries, packs, fills, loads or unloads dangerous goods. A site taking bulk deliveries is an unloader.
- GB REACH Annex XVII entry 69 prohibits placing methanol on the market to the general public in windscreen washing or defrosting fluids at 0.6% or more by weight.
- Road movement is ADR Class 3 with a 6.1 subsidiary risk, Packing Group II, under UN 1230. The small-load threshold is 333 litres per transport unit.
- Inventory matters too: 500 tonnes brings COMAH and hazardous substances consent into scope, and 25 tonnes of dangerous substances in total triggers site notification and marking.
How methanol is classified
Under GB CLP, methanol carries the signal word Danger and five hazard statements. The combination — flammable, acutely toxic by three routes, and organ-damaging — is what shapes every downstream duty.
| Code | Hazard statement | Class |
|---|---|---|
| H225 | Highly flammable liquid and vapour | Flam. Liq. 2 |
| H301 | Toxic if swallowed | Acute Tox. 3 (oral) |
| H311 | Toxic in contact with skin | Acute Tox. 3 (dermal) |
| H331 | Toxic if inhaled | Acute Tox. 3 (inhalation) |
| H370 | Causes damage to organs | STOT SE 1 |
There is no season in which methanol is “cold enough” to treat casually — the flash point sits below normal room temperature. And because the flame is pale and nearly invisible in daylight, methanol fires are routinely discovered late.
UK regulations overview
Every regime that applies to buying, storing and moving methanol in Great Britain, and which duties are yours.
COSHH and exposure limits
The EH40 limits, the skin notation and what a defensible COSHH assessment for methanol contains.
DSEAR and flammable storage
Hazardous-area classification, ignition control, earthing and bonding, and the explosion protection document.
ADR transport and UN 1230
Classification for carriage, the 333-litre threshold, placarding and documentation.
Do you need a DGSA?
The duty that catches receivers: why unloading a tanker may put you in scope, and what to do about it.
Reading a safety data sheet
What a GB-format SDS must contain, which sections matter most, and how to spot an out-of-date one.
Quantity thresholds
COMAH at 500 and 5,000 tonnes, hazardous substances consent at 500, and the 25-tonne notification trigger almost nobody mentions.
Nothing in this section is safety, legal or engineering advice. It summarises the regulatory landscape so that you know which questions to ask and which duties to check. Work from your supplier's current safety data sheet, HSE published guidance and competent advice for your own site and processes.
