Safety matches ignite due to the extreme reactivity of phosphorus with the potassium chlorate in the match head. When the match is struck the phosphorus and chlorate mix in a small amount forming something akin to the explosive Armstrong's mixture which ignites due to the friction.
Can a box of matches explode?
The match heads will rub against the striking strip and ignite. The gases from the flame will need to escape and since the box is almost airtight, a small scale explosion will follow to allow it to escape. Have a fire extinguisher or any other fire safety measures at ready in case an accident happens.

Why a matchstick struck on a matchbox catches fire easily?
The striking surface of the matchbox contains red phosphorus and the head of the matchstick contains potassium chlorate. So when the matchstick is rubbed on the matchbox, some of the red phosphorus is converted to white phosphorus, a chemical i.e. so volatile that it ignites in air.
Why a matchstick struck on a matchbox catches fire easily because?
When the matchstick is rubbed against the match box 's side, it catches fire because on one end of matchstick, red phosphorus is mixed with glass and the side of matchbox also contains red phosphorus, when matchstick is rubbed then red phosphorus turns into white phosphorus in the presence of oxygen.
Why is matching bad?
The chemicals in the match head can cause damage to the kidneys and liver (this is rare).
