What PPE is required for high pressure water jetting?

High pressure water jetting requires strong personal protective equipment (PPE). Operators need waterproof protective clothing, cutresistant gloves, punctureresistant safety boots, a face shield, a safety helmet and hearing protection. The exact PPE depends on the pressure and the working environment. All operators must be protected against highpressure water, flying debris and impact. At DERC Salotech we supply protective clothing from TST Sweden, one of the best global standards for highpressure PPE.

Understanding PPE requirements for high pressure water jetting

High pressure water jetting systems operate roughly between 1,000 PSI (69 BAR) and 43,500 PSI (3,000 BAR). At these pressures, water becomes a cutting tool that can pass through skin, clothing and even some protective materials. The correct PPE is therefore essential. Safety regulations differ per country and job site. Many refer to international highpressure safety guidelines. PPE selection always means using multiple layers of protection. No single item protects against all risks.

What protective clothing do you need for water jetting operations?

Protective clothing must cover the entire body and stop water penetration. Highpressure suits made from PVC, neoprene or advanced synthetic materials are recommended. Reinforced areas at knees, elbows and shoulders improve durability. Cutresistant panels help when debris or sharp fragments may be present. Highvisibility colours and reflective strips help improve worker visibility. Lower pressure work may allow lighter PPE, but ultrahigh pressure requires the strongest suits available.
 For best protection, DERC Salotech offers TST Sweden suits, gloves and boots.

Which safety equipment protects against high pressure water injuries?

Operators need strong protection for head, face and hearing. This includes a safety helmet, fullface shield, goggles if needed and proper hearing protection. Additional safety tools include deadman switches, remote controls and emergency shutoff devices. In enclosed spaces, respiratory protection may be required.

How do you choose the right gloves and footwear for water jetting?

Gloves must protect against cuts, punctures and water penetration. Materials like nitrile, neoprene or advanced synthetics work well. Gloves should offer good grip, even when wet. Safety boots need puncture protection and steel or composite toes. Slipresistant soles are essential in wet environments.
TST Sweden boots meet high PPE standards for water jetting.

What additional safety measures should you consider?

When working at height or in confined spaces, fall protection may be required. Emergency equipment must always be close by, including emergency stop controls, firstaid kits for highpressure injuries and communication devices. Injection injuries can look small but are serious. Always seek immediate medical help.
Clear safety zones, warning systems and emergency procedures must be in place. Good training ensures operators understand these rules.
