Hose and coupling

• Hoses and coupling are mainly used in Oil & Gas plant for: 

– Utility stations: supply water, plant air, steam and N2
– Hydraulic oil: torquing operation etc.
– Fuel and Chemical transfer

• There is a risk of exposure

 

Some HAZARDS related to hoses & coupling involve:

1. Wrong hoses / coupling used
2. Substandard fittings & hoses
3. Incompatibility
4. Temporary arrangements
5. Misuse
6. Lack of inspection & maintenance
7. Failure to renew in time (old materials)
8. Housekeeping and improper storage

 

Example of incidents involving hoses & coupling:

 

The root cause for these incidents: FAILURE to follow recommendations.

INCIDENTS related to hose and coupling failure. 

A pressurized air hose disconnected from torque machine coupling during operation. 

No injury reported.

 

REX: Compressor Incident

What happened? 

Why did this happen?

How can we prevent this from happening again?

Preventative measures and safe practices:

1.         Inspection of hoses and associated couplings prior starting.
2.         Use of standard connections and hoses that met requirement.
3.         Always use anti-whip slings for all pressurized hose connections.
4.         Removed all defective hoses & couplings immediately and replace by proper one.
5.         Use of jubilee clamps is PROHIBITED
