## Narrative

Our technician was working on an air compressor and while holding the part in one hand and using a wrench with his other hand, he was turning the pipe to seal an air leak and noticed an immediate pain.  He reported the injury to his Supervisor and the next day, went to a clinic and was diagnosed with a back strain.
