Gas — Carbon Monoxide/​Dioxide Dwelling (CMDDA1) Assessment

Course outline

The CMDDA1 certification is designed to test the competence of a gas engineer in being able to determine levels of monoxide and the presence of CO2 in a dwelling, as well as identifying the source of the fumes with a portable electronic combustion analyser.

The certification does not extend to commercial properties but will aid Local Authorities and subcontractors responding to calls from their tenants.
