CMDDA1 Carbon monoxide / dioxide atmosphere & appliance testing


This ACS 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 analyser being activated or a report of fumes.

Course details

This two day course consists of one day training with manual, and then one day of practical and theory assessments.  The scope of assessment covers Type A, B & C domestic appliances fitted in dwellings and follows the guidance and procedures outlined in BS7967 Parts 1 to 4. 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 IGEM Industry Standard (IGEM/GL/8).

As will all ACS qualifications, it is valid for 5 years. Candidates must hold a current CCN1/CCLP1, current CPA1 and relevant appliance qualifications.

A certification fee of £80 is applicable to this qualification
