Police in Flint are urgently appealing for information following a break in at Greenfield industrial park over the weekend.
Thieves stole 50 litres of Toluene, 50 litres of Ethanol and four large bottles of Propane gas.
North Wales Police are warning the public that all of these products are highly flammable and pose a safety risk to anyone who has them in their possession.
Toluene and Ethanol will cause irritation if they come into contact with skin or eyes and should only be handled by people wearing the correct protective clothing and equipment.
The containers should not be opened as they will also release vapours which could be harmful if inhaled.
The chemicals are stored in blue plastic containers with the contents clearly labelled.
The Propane gas is stored in red metal gas canisters.
Anyone finding these items, or who has any information on their whereabouts, is asked not to approach them, but to contact North Wales Police immediately on 101, or 0845 607 1001 (Welsh line) 0845 607 1002 (English line) or Crimestoppers anonymously on 0800 555 111.
