A newcomer among CERN self-rescue masks: meet DEZEGA CARBO 30

Anyone entering underground facilities such as the SPS, the LHC and the experimental caverns must be equipped with a self-rescue mask: a life-saving breathing apparatus designed to protect against respiratory hazards such as oxygen deficiency, smoke, toxic fumes and gases.

Access to these areas and the provision of a self-rescue mask is subject to specific safety training courses designed to familiarise the user with the mask's operating principle and the conditions under which it must be worn:

• "Self-Rescue Mask - Initial" is a dedicated three-hour classroom programme (validity: three years) available for the incoming personnel concerned, providing essential information on the use of the self-rescue masks available at CERN and relevant emergency response procedures.
• "Self-Rescue Mask - Refresher" - is a blended learning programme (validity: three years) for personnel already familiar with the masks, which combines interactive e-learning with hands-on practice.

Until now, CERN has used two self-rescue mask models: Honeywell Oxy-Pro and SavOx. The Honeywell Oxy-Pro is currently being phased out and replaced with a new model, the DEZEGA CARBO 30, which is now appearing in the CERN Stores alongside the MSA SavOx model.

While the operating principle of the DEZEGA CARBO 30 is largely the same as other models, there are some differences in how the mask is opened, activated and adjusted.

If you are likely to swap to the new DEZEGA CARBO 30 model in the near future, it is recommended that you enrol in a "Self-Rescue Mask - Refresher" course. Alternatively, you can find a poster and video of the mask's operating procedure and exploded views of the equipment by scanning the QR code below.

Before joining a training session, please ascertain which type of mask you will be using so that the practical part of the training can be adapted accordingly.

If you have been assigned your own mask, please make sure you store it in a suitable location, perform yearly inspections and return it to the CERN Stores if in doubt about its state.

Safety always.
