IMCA SF: Detergent chemical burn

What went right?

The repair of the dishwasher was conducted with proper regard for electrical isolation.

What went wrong?

·         The fact that the detergent, with a pH of 14 and containing sodium hydroxide, was a “hazardous substance” was not considered - Hazardous Substance Register was not consulted.

·         There was no warning label on dishwasher to identify that there was corrosive detergent inside.

·         In use detergents were stored so that labels/warnings were not visible.

Lessons learned

·         Don’t overlook secondary hazards (the detergent) when focusing on primary ones (the electricity).

·         Involve all appropriate stakeholders to ensure a full understanding of risks – particularly if working outside your normal domain.

·         Clearly mark and identify known hazards to ensure good shared awareness.

·         If you find an unidentified water-like liquid on the floor or leaking from a container, always think of the worst-case scenario and wear PPE accordingly.
