The behaviour of gas cartridges when exposed to heat

Concerns were raised  by HSE to storage of large quantities of ‘Bernzomatic’ MAPP gas in 450g cartridges. The fire risk and mitigation control measures appear based on the assumption that cartridges of MAPP behaved in a similar way to propane and comparable to aerosols. It has been reported that MAPP can spontaneously detonate when heated. HSE therefore commissioned a programme of work, comprising a series of experiments on both single and multiple cartridges of MAPP and propane to establish the hazards.
