Safe Use of High-Pressure Hoses

Key Hazards

• Hose whip from failed fittings or sudden pressure release
• Injection injuries from high-pressure leaks or spray
• Leaks from damaged hoses, couplings, fittings, or seals
• Trip hazards from hoses across walkways or work areas
• Hoses damaged by sharp edges, heat, traffic, or crushing
• Unexpected pressure release during disconnect or maintenance

2–3 Minute Talk Script

High-pressure hoses are used with water, air, hydraulic systems, pressure washers, pumps, and industrial equipment. When pressure is involved, even a small hose failure can become a serious hazard.

Workers should inspect hoses before use. Cuts, bulges, cracks, worn covers, leaks, soft spots, damaged fittings, missing guards, or loose couplings should be treated as warning signs.

High-pressure leaks should never be checked with hands. A small stream under pressure can puncture skin and cause an injection injury that may require emergency medical treatment.

Hoses should be routed to avoid sharp edges, hot surfaces, vehicle traffic, pinch points, doors, walkways, and areas where they could be crushed or pulled.

Connections should be secure before pressure is applied. Workers should verify fittings, clamps, couplings, and quick connects are seated properly.

Pressure should be relieved before disconnecting hoses, changing attachments, clearing blockages, or performing maintenance. Stored pressure can release suddenly.

Workers should stay out of the line of fire if a hose, fitting, or connection fails. Hose whip can strike workers or damage nearby equipment.

Safe high-pressure hose use depends on inspection, proper routing, pressure control, secure connections, and stopping immediately if leaks, bulges, or unusual movement are seen.

Safety Reminders

• Inspect hoses and fittings before use.
• Do not use damaged, leaking, bulging, or cracked hoses.
• Never check high-pressure leaks with your hand.
• Route hoses away from traffic, heat, sharp edges, and pinch points.
• Confirm fittings and couplings are secure.
• Relieve pressure before disconnecting or servicing.
• Keep workers clear of hose whip and line-of-fire areas.

Ask the Crew

• Is the hose rated for the pressure and material being used?
• Are there cuts, bulges, leaks, or damaged fittings?
• Could the hose be crushed, cut, heated, or run over?
• Has pressure been relieved before disconnecting or servicing?
• Where would the hose go if it failed or whipped?
