No.23. Burnley.
April 26th.
2 killed, 2 injured.
Small internally fired Boiler, 5ft. high, 2ft. 4in. diameter, and was intended to work at 70 lbs. The fittings were defective, the spiral spring of the safety valve being most easily altered, so as to cause over pressure. The manhole was not strengthened by any ring, and the first rents commenced at that point.
The cause of the explosion was over pressure and defective construction.
The sketch at [No. 57] explosion in this year, is of a similar boiler which exploded from nearly similar causes.
No.24. Bilston. ([Fig. 14.])
