Following are SPIR STAR's lists of Do's & Don'ts for the proper safety practices when using high pressure hose.
Treat high pressure hose with extreme caution. SPIR STAR hoses are wire reinforced hoses with a thermoplastic inner core and should be treated with the same care as a high pressure containment vessel.
When using hoses for water-jetting, read and understand Recommended practices for the Use of Manually Operated High-Pressure Water Jet Equipment (Water Jet Technology Association [+1/314-241-1445, www.wjta.org])
Always visually inspect for frayed, damaged or wear spots before using.
Check the hose end connections and threads for wear, rust, cracks, mechanical abuse or other deterioration that could produce a dangerous projectile.
Know the working pressures and burst pressures of all hoses before using them.
Always use clean, filtered water to prolong hose life. Do not use water that is high in sulphur because sulphur may attack stainless steel.
Always clean, drain and coil hoses after use. Soap and water usually provide an excellent cleaning agent.
Always wear protective gloves, eyewear and garments when handling high pressure hose and water jet lances.
Don’t use a hose with cuts or wire showing through the outer cover.
Don’t use a hose that has been kinked.
Don’t use a hose that has bubbles or blisters in the outer cover.
Don’t exceed the bend radius and pressure rating for each hose.
Don’t run over or crush the hose with heavy vehicles.
Don’t use a hose with corroded or leaking end connections. Take it out of service immediately.
Don’t use hoses that have been exposed to chemical attack or over temperature.
Avoid using dirty water or water with sulphur compounds in it. Tests have documented that hoses fail more rapidly when using water sources from chemical plants and refineries.
Don’t bend the hose over scaffolding or pull heavy equipment with the hose.
Don’t let the hose support its own weight off towers or buildings.
Don't apply torque to the hose assembly.
Don’t expect water jetting or hydraulic hose to last forever.
