Fatal gassing due to methylene chloride : a case report

Methylene chloride is a major component of paint and varnish strippers. Due to its high volatility, its use in unventilated or poorly ventilated confined spaces poses a serious health hazard as a result of accumulation of the solvent vapour. At high levels, methylene chloride can cause severe central nervous system depression and ultimately death, as illustrated in this case report. The importance of adequate forced ventilation, utilisation of proper personal protective equipment and enforcement of a permit-to-work system during work with solvents in confined spaces is emphasised.
