Seaton Burn Colliery boiler explosion, 1860

On the morning of 2 April 1860 a boiler at Seaton Burn Colliery exploded beside a pit-head crowded with men waiting to go down, hurling its six-ton shell 150 yards across the North Road and killing four men.

Cause

One of a row of six boilers, 32 feet by 6 feet 10 inches, which supplied the winding and pumping engines, exploded; it had been almost entirely rebuilt after an explosion at the colliery about twelve years earlier, and had been laid off the previous week to repair loose rivets.

What happened

Seaton Burn Colliery belonged to John Bowes and Co. Five of its six boilers were at work on the morning of Monday 2 April 1860. The night engineman had checked the valves and floats at about eight, and his successor, Wilkinson Younger, had examined them soon after; the alarm float gave no warning. At about twenty to nine the third boiler from the outside sprang from its bed, unseating four of its neighbours and throwing stone and brickwork in all directions. Its main part, about six tons, flew as high as the furnace chimney and came down in a garden across the North Road about 150 yards away. Younger and the stokers Robert Ewing and John Turner were buried in the rubble at the fire-hole: Ewing and Turner were killed and Younger badly scalded. Between 120 and 150 men and boys were gathered at the pit-head to go down; flying stones riddled the roofs of nearby houses, and a labourer on the tramway, William Chevil, was struck on the head.
