EXPLODING VESSELS UNDER PRESSURE at Continental Cement Company LLC
Employee was removing bung from steel drum of waste material to sample contents. Was using a spark resistant tool, but apparently the steel bung caused a spark when it was being removed from the steel lid. This resulted in the lid being blown off the drum striking employee. Employee was wearing gloves, full-face respirator, safety boots and coated tyvek.
