COSHH Assessment — Butane Gas (C4H10 / Liquefied Petroleum Gas)
This pre-completed COSHH assessment covers butane gas (C4H10) — stored as liquefied petroleum gas in portable cylinders and cartridges, used for heating, cooking, soldering and portable equipment across many sectors.
What Does This COSHH Assessment Cover?
The assessment is fully completed and ready to use, covering all sections required for a complete hazardous substance risk assessment:
- Substance identification — trade name, chemical name (butane C4H10 / LPG), SDS reference and physical state
- Health effects and first aid — inhalation, skin contact (cryogenic burns from liquid) and eye contact, with specific first aid for each route
- Asphyxiation and explosion hazard — butane is heavier than air and accumulates in low-lying areas; creates explosive atmosphere at 1.4–8.4% v/v; BLEVE risk from cylinders in fire
- Workplace exposure limits — butane TWA 600 ppm and STEL 750 ppm, from workplace exposure limits guidance
- CLP hazard classification — Flammable and Pressurised gas pictograms
- PPE requirements — including insulated gloves (liquid contact), eye protection and no ignition sources
- Emergency procedures — gas leak response, cylinder emergency and fire procedures
Who Is This COSHH Assessment For?
This assessment is suitable for any workplace where butane gas is used or stored, including:
- Catering and hospitality operations using portable gas equipment
- Construction sites using gas for heating and soldering
- Plumbing and heating engineers
- Leisure and events operations with portable gas appliances
