They will learn to identify potential hazards, understand their responsibilities as operators, and familiarise themselves with essential documentation such as manufacturer's handbooks and risk assessments. The training emphasises the importance of Safe Systems of Work (SSoW) and permit requirements, ensuring that participants are fully aware of the operational and safety standards required in the industry.

By the end of the course, participants will be capable of conducting safety checks, establishing exclusion zones, operating the equipment in various conditions, and executing end-of-shift and shutdown procedures safely and competently.

Course Content

What can I expect from the NPORS High Pressure Water Jet course?

When you enrol in the NPORS High Pressure Water Jetting course, you can expect a comprehensive blend of theoretical knowledge and practical skills training designed to ensure safe and efficient operation of high-pressure water jetting systems. Here’s what the course typically includes:

Theoretical Instruction:

Safety and Legislation: Understanding of relevant legislation such as the Health and Safety at Work Act (HASAWA), Management of Health and Safety at Work Regulations (MHSWR), and others related to equipment use.
Operational Knowledge: Familiarity with the various components of high-pressure water jetting equipment and their functions, along with the risks associated with their use.
Risk Assessments and Safety Systems: Learning how to conduct robust risk assessments and develop Safe Systems of Work (SSoW) for high-pressure water jetting tasks.

Practical Training:

Equipment Handling: Hands-on training in setting up, operating, and managing high-pressure water jetting equipment, including the use of hand and flex lances for different cleaning operations.
Safety Protocols: Instruction on how to properly inspect and select personal protective equipment (PPE) and how to perform pre-start safety checks on the equipment.
Real-World Application: Practical exercises that include the establishment of safety zones, effective communication with pump operators and other crew members, and the proper shutdown and stowing of equipment.

This course is designed not just to teach the mechanics of operation but also to instil a deep respect for the safety procedures and environmental considerations necessary in the high-pressure water jetting field. It is suitable for those new to the field as well as experienced operators looking to formalise and update their skills.

Entry Requirements

Are there any entry requirements for the NPORS High Pressure Water Jetting course?

Please be aware that all operators must provide documentation to support their application. This includes proof of having passed the CITB Health, Safety & Environmental test within the two years leading up to their application. Additionally, a proficient understanding of both spoken and written English is required.

Assessment

The NPORS assessment features both theoretical and practical elements. The theoretical part comprises a combination of multiple-choice and open-ended questions. Furthermore, participants undergo a practical assessment where they apply their skills in real-world scenarios.

Certification

Existing NPORS Card Holders Without (S)NVQ:

Operators without the necessary (S)NVQ qualifications will be issued a Trained Operator card, which remains valid for two years. Within this period, they must enrol in and successfully complete the relevant (S)NVQ pertaining to the types of plant equipment listed on their card.

Existing NPORS Card Holders With (S)NVQ:

Operators who possess an (S)NVQ qualification will receive a Competent Operator card, which has a validity of five years. Additionally, they will be provided with a CPD record/operator logbook to track their continuous professional development and log hours of operation in their field of work.

FAQs

What is the maximum pressure for hydrojetting?

The maximum pressure used in hydrojetting, which involves using high-pressure water streams to clean or cut through materials, can vary widely depending on the application and the equipment used. Typically, hydrojetting systems can operate at pressures ranging from:

Low Pressure: Around 5,000 to 10,000 psi (pounds per square inch) for lighter cleaning tasks such as removing dirt from surfaces or cleaning residential sewer lines.
Medium Pressure: Approximately 10,000 to 25,000 psi for more intensive cleaning jobs or for industrial applications like removing paint or heavy deposits.
High Pressure: From 25,000 to 40,000 psi, used in heavy industrial cleaning and for cutting through harder materials.

In some extreme cases, especially in industrial settings where very tough materials need to be cut or cleaned, ultra-high-pressure hydrojetting systems can be used that operate at pressures up to 55,000 psi or even higher. These systems require special safety measures and highly durable equipment due to the intense force of the water stream.

What precautions should be taken during high pressure water jetting?

High pressure water jetting is a powerful tool for cleaning and cutting, but it comes with significant safety risks. To mitigate these risks and ensure safe operation, several precautions need to be taken:

Proper Training: Operators should be thoroughly trained in the use and maintenance of high pressure water jetting equipment. They must understand the operational procedures and safety protocols.

Use of Personal Protective Equipment (PPE):

Eye Protection: Safety goggles or face shields to protect against flying debris.
Hearing Protection: Earplugs or earmuffs due to the high noise levels.
Hand and Body Protection: High-strength gloves, waterproof and cut-resistant clothing, and boots to protect against high-pressure water streams.
Helmet: To guard against head injuries from flying debris or accidental slips.

Equipment Checks: Before use, all equipment should be inspected for any signs of wear or damage. Hoses, nozzles, and connections must be checked for integrity to prevent any sudden disconnections or ruptures under high pressure.

Establishing a Safe Work Area:

Exclusion Zones: Set up barriers or mark zones where unauthorised personnel are not allowed to enter during jetting operations.
Signage: Use clear signs to warn of high-pressure water jetting in progress.
Secure Equipment: Ensure that the jetting equipment, including hoses and pumps, is securely positioned and cannot move unexpectedly.

Risk Assessment and Planning: Conduct a thorough risk assessment to identify potential hazards related to the specific environment or job. Plan the operation to minimise risks, including controlling runoff and debris.

Communication: Maintain clear communication between all team members involved in the operation. Use radios if necessary, especially in loud environments where normal speech may not be audible.

Emergency Procedures: Have clear, well-practiced emergency procedures in place. This includes quick shut-off protocols for the equipment and first aid measures.

Environmental Considerations: Manage wastewater and debris appropriately to prevent environmental contamination. Be aware of and comply with local regulations regarding waste disposal.

By implementing these safety measures, operators can minimise the risks associated with high pressure water jetting and protect themselves and others in the vicinity.
