Summary: A worker suffered a fluid injection injury when a hose fitting on a high pressure wash down wand failed.
The hose whipped around and the person was hit on the chest and the left forearm with the high-pressure water.
Recommendations to industry:
- Mine operators should inspect high pressure cleaning equipment to ensure the hose, connection fittings and lance (gun) are assembled correctly from original equipment manufacturer (OEM) recommended and rated components.
- Hose-to-gun connection should contain a swivel connection or methods to prevent the connection from becoming unscrewed if twisting occurs in the hose.
