Common operator requirements for a hose assembly
- Working Pressure (W.P.) should never be exceeded.
- Always rate the Working Pressure of the hose assembly by the lowest rated component (hose W.P. or coupling W.P. attachment method, whichever is lowest).
- Only use the hose assembly for the service marked on the product or for those services recommended in print. Contact your local Goodall distributor about other applications before the hose assembly is put into use.
- Have a Hose Inspection and Test Plan to insure unsafe hose and/or worn, damaged or corroded cou¬plings are removed from service.
- Test all hose assemblies as required to insure the assembly is safe for use. (Use manufacturers, RMA, ASTM, NAHAD, other industry associations or regulatory bodies’ recommendations for pressure testing along with these recommendations.)
- Train all individuals using any Goodall hose as to the conditions associated with an unsafe hose. The operator is the last line of defense against spills and injuries. Instruct your employees that: “When in doubt, Remove the Hose From Service!”
- Always use the appropriate Chemical Resistance Charts to verify that the chemical or product transferred is compatible with the hose tube. “Remember, the temperature and concentration of the chemical/product conveyed must not exceed the manufacturer’s recommendations.” Employees using chemical hose should always wear appropriate PPE (safety protection) to guard against accidental spills and splashing. Some examples of PPE are: safety clothing, hard hat, eye protection, protective wear, boots, gloves, or other safety protection as dictated by operating conditions.

8. Always use a coupling made from material suitable for the application and the product conveyed. Refer to manufacturer’s recommendations.
9. For hoses coupled with adjustable clamps, re-tighten clamps as recommended by the manufacturer and use the manufacturer’s recommended torque values. It is always good practice to inspect clamps before use. If the clamps can no longer be tightened, cut off the coupling, thoroughly externally and internally inspect the hose and couplings then re-attach a coupling on another part of the hose per the coupling manufacturer’s recommendations.
10. It is recommended that recoupled hose be hydrostatically tested prior to being returned to service.
11. Before each use of the hose assembly, always check the coupling. If there is a question concerning slippage, remove hose from service.
