two contractor’s workers were contacted with diluted caustic solution while cleaning the phenol tank from outside the tank manhole, with a fire water hose.
The worker holding onto the hose nozzle was decked in PPE as required for caustic solution, while another worker holding onto the length of the hose was only decked in basic PPE.
Both workers sustained moderate burns at chest & shoulder when the hose suddenly ruptured. First aid treatment was rendered immediately by the trained first aider.
The workers were sent to the hospital for medical treatment.
