Safety matches only ignite on the box striking strip chemical surface

Separating match head chemicals from phosphorus prevents accidental ignition

Unlike early friction matches that ignited on any rough surface, safety matches separate key reactive chemicals. The match head contains potassium chlorate and sulphur, while red phosphorus is glued exclusively onto the box striking strip. Friction converts red phosphorus to white phosphorus, igniting the match head safely.
