In the late 1930s, as the conflict of the Second World War started brewing, it was expected that gas would be used as a weapon against the British as it had been during WW1. Much work was put in before war broke out to equip both the armed forces and civilians with suitable counter-measures to protect against the horrific effects. Jars of anti-gas ointment went on general sale in grocery shops and chemists.
The ointment was intended for use to protect the skin against mustard or liquid blister gas. It could be applied either as a thin film in advance to prevent gas from damaging the skin surface and flesh, or as a counter-acting remedy after contamination. It relies upon a strong alkaline content to neutralise the gas residue.
