Pre-purchase chimney and appliance inspection


Overview
The purpose of this standard is to provide the candidate with the knowledge to perform a pre-purchase inspection of flues and chimneys.

Duration

Minimum 1 day of 6 learning hours per day

Purpose/scope

The purpose of this standard is to provide the candidate with the knowledge to perform a pre-purchase inspection, in order to determine if an appliance is suitable and safe for use for a particular flue/chimney.

The scope of this standard covers:

  • existing or proposed installations
  • chimneys and flues for: coal, oil, biomass, wood, and gas
  • how to follow the inspection process and use the inspection checklist
  • how to assess the hazards/risks for fire and health and safety
  • how to check safety devices such as carbon monoxide alarms
  • how to diagnose faults with the appliance
  • how to inspect for structural failure, masonry design, and flue system compliance
  • how to check and compare specifications and installation drawings
  • how to record and report defects, non-compliances, and rectifications
  • legislation, codes of practice, building regulations, and BS/EN standards, relating to the design and installation of flues, including fire, safety and environment

Occupational relevance

Training delivered against this standard would be relevant to the following occupational groups:

  • operative and craft
  • supervision.

Candidate pre-requisites

There are no candidate pre-requisites as part of this standard. However, it would be beneficial if candidates had experience in the relative industry.

Instruction/supervision

As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

  • a train the trainer or instructional techniques course certificate
  • Successfully completed training to this standard
  • at least 2 years relevant industrial experience
  • a verifiable CV.

Delivery

The following methods may be used in the delivery of this standard:

  • classroom

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.

This standard is considered to contain 51 per cent or more theoretical learning.

Assessment

For the successful completion of training, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.

Quality assurance

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard.

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the Training Standard.

Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB quality assurance team.

Renewal/refresher

There are no mandatory renewal or recommended refreshment requirements for this standard.

Approval date

November 2018

Review cycle

Either on request or in 3 years from approval date.
