Chanters Colliery Explosion, 1957

Gas that had accumulated in Chanters Colliery's No. 2 drift after a roof fall five days earlier was ignited by an electrical arc when an electrician twisted a switch's cover plate onto a live busbar, killing eight men.

Cause

Gas had been accumulating progressively in the No. 2 drift for five days following a roof fall on the development face there, aggravated by reduced air circulation. It was ignited when an electrician twisted the cover plate of a switch, which came into contact with a live busbar and produced an electrical arc.

What happened

A roof fall on the development face of Chanters Colliery's No. 2 drift, five days before the disaster, allowed gas to begin accumulating in the drift as air circulation there was reduced. On 6 March 1957, an electrician twisted the cover plate of a switch, which came into contact with a live busbar; the resulting electrical arc ignited the accumulated gas. Eight men died — four in the explosion itself and four more from their injuries afterward — and three more were injured but survived. Recovery teams working in self-contained breathing apparatus began locating bodies from around 4pm, with four recovered by 6:40pm; survivors either made their own way out or were guided to safety.

Rescue & recovery

Recovery teams in self-contained breathing apparatus began locating the dead from around 4pm, with four bodies recovered by 6:40pm; the survivors either self-evacuated or were guided to safety by rescuers.

Investigation & inquiry

HM Divisional Inspector G. Hoyle investigated the explosion and concluded that electricians had been working on live apparatus without proper safety protocols — a practice he identified as a recurring danger across the industry, not unique to Chanters.

• Roof Fall (contributing factor)
  A roof fall five days before the explosion reduced air circulation in the No. 2 drift, allowing gas to accumulate there undetected.
