TITLE
Employee injected with hydraulic oil
COUNTRY OF ORIGIN
United Kingdom
ACCIDENT / INCIDENT DETAILS
A quarry supervisor suffered a serious hand injury when a hydraulic hose burst and he was injected with hydraulic mineral oil.

The supervisor was undertaking maintenance activities on site and was in the process of raising the hood of a mobile primary crusher to gain access to the isolated rotor chamber, when a hydraulic hose connected to the hood's lifting ram ruptured.

The supervisor's hand was directly in front of the ruptured hose and a high-pressure 'needle-like' jet of hydraulic oil projected from a small hole in the hose wall, penetrated through the supervisor's leather 'rigger' glove into the palm of his hand, injecting him with hydraulic mineral oil.

The supervisor required emergency surgery in hospital to treat his injured hand.

Cause of failure

On inspection the ruptured hydraulic hose was found to have surface abrasion damage.
The damage was caused by plant vibration and the hose chafing against a steel floor-plate.
