A Member has reported that while extending an hydraulic arm on a tooling system using a (enerpac) hydraulic pump, rated for 10,000 psi (680 bar), the output hose burst next to the coupling at the end of the output hose.
Our member’s investigation revealed the following:
On investigation, it was found that the enerpac output hose was rated for 3,000 psi (200 bar) and had been damaged (kinked) prior to use. In addition to this, the enerpac pressure gauge was facing away from the pump operator, resulting in the operator not knowing what pressure the enerpac was generating. Fortunately in this case no injuries were sustained.
The contractor involved has issued the following reminder to its personnel:
- Equipment such as hydraulic hand pumps (Enerpac) and associated equipment should be visually inspected prior to use for damage, to ensure integrity and to ensure that pressure gauges, etc., are working correctly.
- Always use a gauge to verify system pressure.
- Be aware of the safe working pressure of all parts of the system – the output hoses may be rated at a lower pressure than other parts of the system.
- Full personal protective equipment (PPE) including eye protection should be utilised by all personnel in the area, not only the system operator.
- Risk assessments should be revisited.
