3. Applications and Machines

Scope of surface cleaning and preparation applications. Range of tasks, and differentiation between surface cleaning & surface preparation. Range of Jetting Machines suitable for surface cleaning/preparation.

4. Jetting Equipment – Nozzles and Ancillaries

Review nozzle principles – fixed jet nozzles, rotating nozzles, life & wear characteristics, associated ancillary equipment including automatic, semi-automatic, and wet abrasive blasting.

5. Jetting Equipment – High Pressure Hose

Hose used in surface cleaning and preparation applications, damage & wear possibilities, hose ancillaries. Review bore size and flow ratings.

6. Jetting Equipment – Machines

Range of jetting machines used, engine controls and instruments. Pump pressure controls, review dump/dry shut and selector/ fail safe types, auto engine speed control systems, pressure safety relief. Water supply/delivery features – filtration requirements, boost feed pumps, built-in anti-freeze provisions.

7. Job Assessment and Planning

Information and assessment – site location, access to work area, surface to be cleaned and layout; base material and contaminants – initial condition and require finished condition; water provision, waste disposal, hazards. Selection of equipment and manning levels – jetting machine/nozzles/accessories, number and duties of operators, single person operation. Determine job method, based on safe system of work.

8. Operational Procedures

Daily checks – manufacturer’s instructions, other items requiring regular checks. Setting-up – permits/authorisations, barriers and warning signs, positioning of machine and equipment, team duties and signals, flushing, leaks check, trial run. Monitoring of operation – flying debris, waste contamination, work standard. Job completion – client inspection, waste removal, equipment decontamination, return site to safe condition.

9. Practical Exercises

Jetting machine and equipment – review features, and demonstrate daily checks, start/run/stop. Job assessment – review and discuss, site location and constraints, accessibility, screening/extraction requirements. Work surface – nature of contamination, work to be carried out and standard of finish. Water supply, effluent drainage. Hazards & use of PPE. Discussion of options and agree job method. Site preparation – setting up work area. Team talk – review job method, signal, set up team(s). Position jetting machine, layout and check equipment. Demonstrate all procedures to full group. For all teams, instruct each operator in each duty. Trainees carry out exercise, each team following instructions to set up, flush, check for leaks, carry out trial run, proceed with operation. Rotate team members through duties. Review at each rotation and final review. Disconnect equipment and clear site.
