Our clients were part of a fracing crew. As the fracing crew primed its pumps to prepare for the next stage of the operation, a pinhole leak was reported from the low pressure side of the manifold. Four men went to investigate. Before the problem could be assessed, the end of the manifold exploded, killing one man and injuring two others. Investigation revealed that the manufacturer of the manifold had failed to weld the endplate to the manifold properly. The manufacturer settled for a confidential amount.
