Logic4training promotes gas safety at Energy Efficiency Show!

Yesterday’s (25th September) Energy Efficiency Show saw our very own Mark Krull, marketing director, take to the stand at Esher Town Hall, championing the importance of best practice in the detection of CO and CO2 within domestic properties.

Logic4training were invited to exhibit alongside Gas Safe Register in a bid to raise awareness of gas safety and how the appropriate installer training can help keep homeowners from the dangers of carbon monoxide poisoning.

The hot topic was CMDDA1, the ACS module launched last year to bring gas fitters up-to-speed on the correct way to respond to a CO2 alarm which has been activated.

Is your training is up to scratch with the latest CO and CO2 requirements?

Reports of CO need to be dealt with in line with the standard BS7967: carbon monoxide in dwellings and the combustion performance of gas-fired appliances.

Module CMDDA1 teaches operatives how to determine ambient levels of CO and CO2 and the correct response procedures. Assessment covers:

  • Carrying out ambient CO and CO2 sampling and combustion performance analysis using electronic portable has analysers on domestic gas appliances in dwellings following –
  1. A genuine report of fumes and smells
  2. A genuine report of the activation of a CO alarm
  • Investigating the report of the spillage or leakage of combustion products and the correct methods to ensure appliances and the dwelling are safe.

The dwelling type will determine what ACS certificates must be held prior to taking CMDDA1. For example, gas engineers intending to investigate suspect Natural Gas installations in domestic dwellings must hold valid ACS certificates for CCN1 and domestic appliances, plus CPA1 or equivalent gas services N/SVQ. Likewise, where the dwelling uses Liquefied Petroleum Gas (LPG) the appropriate core or changeover and appliances must be held.

As with all ACS modules, CMDDA1 is available as assessment only. It is strongly recommended that gas engineers familiarise themselves with the content, procedures and guidance provided in BS7967, parts 1-4, in preparation. This can be done as either self-study or guided training within an approved centre. Gas engineers should also ensure that they are familiar with the electronic equipment that will be used during atmosphere sampling.
