Emissions for defective appliances and chimney systems 


Standard details
The purpose of this standard is to provide the candidate with knowledge to determine defective appliances and chimney systems, and their emissions.

CITB has developed this standard in discussion with industry

Duration

Minimum 1 day of 6 learning hours

Purpose/scope

The purpose of this standard is to provide the candidate with knowledge to determine defective appliances and chimney systems, and their emissions.

The scope of this standard covers: 

  • chimneys and flues for: coal, oil, biomass, wood, and gas
  • how to identify chimney system components• how to operate appliances
  • how to identify defective chimney systems, appliances and mechanical parts
  • how to identify incorrect parts and materials
  • leakage of carcinogenic material
  • fire risk
  • general safety
  • CO emissions (carbon dioxide)
  • consumer health and respiratory issues
  • main legislation, codes of practice, building standards, 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.
