Introduction
High pressure water jetting and tank cleaning sit among the most injury-prone jobs of any shutdown: a jet that pierces skin, a hose whip, a sludge pocket releasing hydrogen sulphide or a scale deposit that ignites once air reaches it. Refineries, petrochemical plants, power stations and utilities hand much of this work to contractors, so controls depend on sound planning and supervision. This Core Concept course equips the people who plan, supervise and audit jetting, vacuum and de-sludging crews. Each participant produces a Cleaning Job Safety Plan for a case tank and heat exchanger.
Course Objectives
- Classify high pressure water jetting equipment by pressure class, pump type and tool, and match each to the cleaning task
- Set exclusion zones, operator PPE and team roles for jetting crews working on bundles, pipes and vessels
- Inspect and test pumps, hoses, fittings, lances and dump controls before and during a jetting job
- Control tank cleaning and de-sludging hazards, including gas-freeing, pyrophoric iron sulphide, hydrogen sulphide, benzene and static discharge from vacuum trucks
- Organise first response for fluid injection injuries and other cleaning emergencies
- Prepare a Cleaning Job Safety Plan that links risk assessment, permits, equipment checks and waste routes for a tank and exchanger
Target Audience
- HSE advisors who review cleaning method statements and audit jetting and vacuum crews in the field
- Cleaning supervisors who direct jetting, hydro-blasting and de-sludging teams on shift
- Contractor leads who plan crews, equipment and procedures for industrial cleaning contracts
- Turnaround and maintenance coordinators who schedule bundle, pipe and tank cleaning within shutdown windows
- Operations representatives who hand over tanks and exchangers for cleaning and accept them back

- Tank De-Sludging Supervision
- Pyrophoric Scale Control
- Vacuum Truck Static Control
- Injection Injury First Response
- Cleaning Waste Management
Why Attend This Course
- Leave with a Cleaning Job Safety Plan for a case tank and exchanger that can be adapted to your next shutdown
- Know which equipment defects, zone breaches or gas readings should stop a jetting or de-sludging job
- Challenge contractor method statements with specific questions on pressure class, tools and team roles
- Compare cleaning practice with HSE and contractor staff from refining, petrochemical, power and utility sites
Conclusion
Industrial cleaning is routine work with non-routine consequences when a hose fails, a jet strikes a hand or a sludge bed releases gas. The course moves from incident patterns and cleaning methods, through jetting equipment and codes of practice, to running jetting, bundle and tank de-sludging jobs, and on to pyrophoric, toxic, vacuum and chemical hazards with first response. The final day applies this to a case tank and exchanger, producing a Cleaning Job Safety Plan that participants can carry into their next turnaround.
