Morphology
The meaning 'a protective head covering designed to guard against poisonous gases' is directly and transparently derived from combining 'gas' (a gaseous/poisonous substance) with 'helmet' (a protective covering for the head). This simple noun–noun compounding follows common cross-linguistic patterns, so an average B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
Gas helmet comes from World War I when soldiers put on a heavy, helmet-like mask that covered the whole head to keep out poisonous gas. Because it looked like a helmet that 'protected' against gas, the name came to mean a protective mask.
