WJA – Drain and Sewer

Brief Description

This minimum 4hrs session is aimed at:

  • People who operate drain and sewer jetting equipment.
  • A personal copy of the Drain and Sewer water jetting “Red code” is provided during the course and this document is used as a reference throughout.
  • People who manage and design drain cleaning tasks using water jetting equipment.
  • The safety awareness course must be completed prior to attending this course. The Safety awareness card / certificate is valid for three years before it needs to be renewed for a further three years.

This course provides knowledge and assists in the understanding of drain and sewer cleaning by means of assessments in:

  • Theory.
  • Operational skills.
  • Understanding and knowledge.
  • Safe use of equipment.

Assessments are a balance of theory in a classroom environment and practical using live water jetting equipment.

For DSP, training will include carrying out surface preparation using a jetting gun with a protective shroud with hose whip checks for additional safety.

The pressure will not exceed 275 bar (4,000 psi) and candidates must be able to comfortably control the jetting accessories, this includes managing reaction force through manual handling.

The training does NOT cover works that involves confined space entry into chambers, tanks, wet wells, or vessels. To carry out work in these conditions, operatives must have passed a recognised confined space entry course.

The WJA’s aim is to eliminate the use of wash-down nozzles and for operatives to have optimum control over the delivery of water using a jetting gun with a trigger mechanism.

Delivery

Classroom theory and practical assessment.

Why?

  • Assists in the compliance with Health & Safety at Work Act 1974 (HASWA 74).
  • High pressure water jetting is very hazardous process; therefore, it is a requirement for anyone involved in cleaning drains and sewers using water jetting to have knowledge and understanding of the hazards involved in water jetting so they can operate safely.
  • This includes typical hazards, Legal requirements, pre-start checklist, safety devices, competent teams, water jetting equipment, health concerns and typical controls and PPE.

Who Should Attend

  • New operational candidates.
  • Water jetting candidates that are refreshing their WJA card which is near its expiry date.
  • Managers
  • Supervisors
  • Site owners
  • Permit issuers
  • Health and safety Managers / officers

Content – Candidate Outcomes

This course will equip delegates with the tools to:

  • Receive a copy of the WJA red code of practice and review best practice contained within the code.
  • Understand the hazards involved when cleaning Drains / Sewers
  • For DSP (in addition), cleaning a surface by utilising safe use of a jetting gun.
  • Understand health and safety and the hierarchy of control when applied to a water jetting task.
  • Have knowledge of the potential injury that can be caused by a water jet / pressurised system failure.
  • Understand daily checks and identify hazards on equipment prior to start up.
  • Understand what makes a competent team when cleaning drain / sewers and using a jetting gun.
  • Understand potential hazards within a water jetting task on cleaning drains and sewers. (DSP includes cleaning surfaces with a jetting gun).
  • Understanding how to prevent a water jetting injury and action taken as specified in the red code of practice.
  • Understand what we need to do to leave the area safe & secure.
