8 weeks · About 6 hours per week
Hydroblasting Safety and Hazard Awareness
Define hydroblasting and distinguish it from pressure washing and other high-pressure cleaning methods.
List the primary hazards of hydroblasting (high-pressure injection, impact, noise, flying debris, chemical exposure, confined space) and describe the injury mechanism for each.
Explain the purpose and correct use of personal protective equipment (PPE) including pressure-rated gloves, face shields, and hearing protection.
Identify the key sections of a job safety analysis (JSA) and describe how to participate in one for a hydroblasting task.
Your checkpoint
Create a one-page hazard identification checklist that lists at least eight hydroblasting hazards, their warning signs, and the corresponding PPE or control measure.
Hydroblasting Safety and Hazard Awareness & Hydroblasting Equipment and Components
Describe the components and safe operation of high-pressure pumps, hoses, fittings, and nozzles.
Explain the importance of pressure ratings and the consequences of mismatched components.
Identify the steps for safely setting up a hydroblasting job site, including barricades, signage, and communication.
Demonstrate how to perform a pre-operation inspection of hoses, fittings, and the pump.
Your checkpoint
Write a step-by-step pre-operation inspection checklist for a high-pressure pump, hose, and nozzle, including at least ten checkpoints.
Hydroblasting Equipment and Components & Hydroblasting Operations and Procedures
Explain the function and operation of unloaders, relief valves, and dump valves in a hydroblasting system.
Describe the procedure for safely starting up and shutting down a hydroblasting system.
Identify the correct nozzle type (e.g., fan, straight, rotating) for different cleaning tasks and explain the selection criteria.
Demonstrate proper hose routing and connection techniques to prevent stress and failure.
Your checkpoint
Produce a system diagram labeling the main components (pump, unloader, relief valve, hose, nozzle) and write a short paragraph explaining the flow and safety function of each.
Hydroblasting Operations and Procedures & Surface Preparation and Cleaning Applications
Describe the steps for preparing a surface for cleaning, including assessing the substrate and selecting the appropriate pressure and nozzle.
Explain the procedures for cleaning different surface types (metal, concrete, coatings) without causing damage.
Identify the factors that affect cleaning efficiency, such as pressure, flow rate, standoff distance, and dwell time.
Demonstrate how to perform a test patch to determine optimal cleaning parameters.
Your checkpoint
Create a surface preparation and cleaning procedure for two different substrates (e.g., concrete and steel), specifying pressure ranges, nozzle types, and safety precautions.
Surface Preparation and Cleaning Applications & Inspection, Maintenance, and Troubleshooting
Explain the inspection and maintenance requirements for high-pressure pumps, hoses, and nozzles.
Describe common failure modes of hydroblasting equipment (e.g., hose burst, nozzle clog, seal leak) and their symptoms.
Demonstrate how to troubleshoot a loss of pressure using a systematic approach.
Identify the steps for storing and maintaining equipment to extend its service life.
Your checkpoint
Develop a troubleshooting flowchart for a low-pressure or no-pressure issue, listing at least five potential causes and the corresponding checks or corrective actions.
Inspection, Maintenance, and Troubleshooting & Hydroblasting Safety and Hazard Awareness
Describe the procedure for inspecting and testing safety devices such as relief valves and pressure gauges.
Explain the record-keeping requirements for equipment inspections and maintenance.
Review incident reports or case studies to identify root causes and preventive measures.
Demonstrate how to conduct a safety audit of a hydroblasting job site.
Your checkpoint
Write a safety audit checklist covering equipment condition, PPE use, barricades, and communication, with at least 15 items.
Hydroblasting Safety and Hazard Awareness & Hydroblasting Operations and Procedures
Explain the emergency response procedures for hydroblasting incidents, including injection injuries and hose failures.
Describe the communication protocols and roles during an emergency.
Demonstrate the correct first aid steps for a high-pressure injection injury.
Identify the reporting requirements for incidents and near misses.
Your checkpoint
Create an emergency response plan for a hydroblasting job, including contact numbers, first aid steps, and evacuation routes.
Hydroblasting Equipment and Components & Hydroblasting Operations and Procedures & Surface Preparation and Cleaning Applications & Inspection, Maintenance, and Troubleshooting
Review and integrate key concepts from all domains.
Complete practice questions covering all domains to identify weak areas.
Explain the relationship between equipment selection, operating procedures, and safety outcomes.
Demonstrate comprehensive knowledge by teaching a short lesson on a hydroblasting topic to a peer.
Your checkpoint
Score at least 80% on a 50-question practice exam covering all domains, and write a reflection on areas needing further study.
Milestones
Week 4: Successfully complete a hands-on demonstration of setting up and shutting down a hydroblasting system, including a pre-operation inspection, without critical safety errors.
Week 8: Pass a comprehensive final assessment with a score of 80% or higher, and submit a completed study portfolio including all checklists and procedures.
