This gas safety assessment is designed to test the competence of an operative in determining ambient levels of CO and presence of CO2 in dwellings and identifying the cause of fumes using a portable electronic combustion analyser. This will typically be any engineer who responds to the genuine report of a CO alarm being activated or a report of fumes.
The scope of the assessment covers Type A, B & C domestic gas appliances fitted in dwellings and follows the guidance and procedures outlined in BS EN 7967 Part 1 to 4. Further guidance has also been issued by HSE in the form of HSE Guidance Notes HSE(EH)40 and HSE(L)56, Gas Safety (Installation & Use) Regulations. Further guidance is expected from IGEM in the near future.
It does not cover commercial premises and appliances or the procedures to adopt following an incident reportable under RIDDOR. Where an engineer is required to carry out a formal CO incident investigation on behalf of a gas supplier as part of their obligation under gas safety legislation, the engineer would need to have successfully achieved a relevant qualification in the investigation of CO poisoning and carry out the investigation in accordance with the Institution of Gas Engineers and Managers (IGEM) Industry Standard (IGEM/GL/8)
CCN1/CCLP1 + CPA1) or CCN1/CCLP1 as from 1st April 2012 or valid equivalent NVQ or QCF qualification + appropriate domestic appliance(s)
This is regarded as having an equivalence to a Level 3 qualification.
Different working situations require different qualifications and there are so many, particularly with gas, it can be difficult to keep up.
You need to make sure you are working within the law and have the correct qualifications.
So when is CMDDA1 sufficient and when is it not?
CMDDA1 is required if you want to investigate a report of fumes or CO alarm activation in accordance with BS 7967 and use an ECGA (Electronic Combustion Gas Analyser) to draw conclusions about the gas appliances in the premises.
When you carry out GSIUR 26(9) appliance safety checks following gas work, which may or may not follow a report of fumes, you do not need CMDDA1.
If you wish to carry out incident investigation (fatality or major injury), you need a specialist qualification: CMDDA1 is not appropriate nor is it sufficient.
Gas Safe Register stress that any activities covered by BS 7967 are not aimed at people who are involved in investigating deaths or major injury as investigations relating to these types of incidents (RIDDOR 11(1) reportable), must only be undertaken by suitably qualified people under direction of a gas supplier and/or relevant health and safety enforcement authority, following the guidance given in IGE/GL/8 edition 2 published by IGEM.
Incident investigations require a specialist competence/qualification to conduct them in accordance with appropriate standards, such as IGE/GL/8 reporting and investigation of gas related incidents.
Engineers who undertake formal investigations must be able to prove their competence, especially with regard to their own safety and the safety of others who might be in the building. Achieving CMDDA1 does not provide such proof of competence.
CCTS delivers a comprehensive 2 day CMDDA1 course designed to test the competence of gas installers.
