01Hydroblasting Safety and Hazard Awareness
Hydroblasting Safety and Hazard Awareness tests your ability to recognize what makes high-pressure water different from other industrial cleaning methods - injection injury, stored energy, and uncontrolled jet reaction - and to apply the controls that prevent them. Injection injury is the signature hazard.
359 words, about 2 min02Hydroblasting Equipment and Components
Hydroblasting Equipment and Components tests how pumps, hoses, lances, nozzles, and pressure controls work as a system, and how changing one component alters pressure, flow, and safety everywhere else. Positive-displacement triplex plunger pumps are standard; ultra-high-pressure work may use intensifiers.
331 words, about 2 min03Hydroblasting Operations and Procedures
Hydroblasting Operations and Procedures covers the sequence of a job: permits and job safety analysis, setup, pressurization, lance work, and shutdown. Exam questions tend to focus on order of operations and on what to do when something abnormal happens.
309 words, about 2 min04Surface Preparation and Cleaning Applications
Surface Preparation and Cleaning Applications tests whether you can match waterjetting standards, nozzle type, standoff, and pressure/flow to the specified result - and recognize the standard that defines acceptance. Waterjetting cleanliness is defined by SSPC-SP 12/NACE No.
289 words, about 1 min05Inspection, Maintenance, and Troubleshooting
Inspection, Maintenance, and Troubleshooting tests the daily checks and diagnostic reasoning that keep a hydroblasting unit safe and productive - and the discipline to stop when a component is out of specification. Pre-use inspection: hoses for cuts, bulges, blisters, exposed wire, and a current test tag; fittings and whip checks; nozzle orifice with a gauge; deadman function; relief valve; filters; gauges.
