Safe Working in Oxygen Depleted Areas

Apr 11 2018

As CO2 is a mild asphyxiate, pockets of CO2 caused by gas leaks in the workplace can be hazardous to personnel. Asphyxiant gas reduces or displaces the normal concentrations in breathing air causing oxygen depletion.

Operating around process machinery can be dangerous. At exposure levels above 5% vol, personnel will begin to feel fatigue to the point of exhaustion and headaches.

You can protect personnel against the danger of asphyxiation caused by oxygen depletion by means of installing an oxygen depletion alarm system.

a1-cbiss specialise in the supply of oxygen depletion systems used in various industrial environments which are designed to keep you safe at work. a1-cbiss have a team of gas detection consultants who can advise you on the most appropriate oxygen depletion system for your application following a site survey.

An experienced team of qualified engineers with expert knowledge of gas leak detection equipment are the perfect partner to design, build, install and service your permanent fixed gas detection system.

Considerations are made not only satisfy health & safety regulations but to ensure that the system is fit for purpose within the environment. Area classification, product output requirements, ingress protection, sensor positioning and installation considerations are just some of the aspects that our trained engineers will be taking into account during the site survey.

The a1-cbiss have years of experience of providing a proven solution within the brewing industry.

To ensure a safe workplace, a fixed gas detection system is specified to provide visual warnings, communication to extraction or ventilation systems once alarm levels are reached and integration to data acquisition and reporting software.

A typical proposal consists of a proven solution for gas sensors positioned installed in each of the hazardous areas – Oldham CTX300 CO2 and Oldham OLCT100 O2 gas sensors, which will be cabled back to a central MX43 control panel.

a1-cbiss are one of the few UK gas detection companies that can supply the whole package from specification right through to system installation and ongoing service support.

A bespoke fixed gas detection system provides a more flexible system than portable gas detectors with regards to how they can integrate into existing building management system or process control.

The oxygen depletion sensors usually have a range of 0-25% oxygen with the first stage warning alarm set to 19.0% oxygen. A second stage full alarm at 17.0%. An early warning system enables actions to be taken prior to a required evacuation as a last resort.

Traffic light beacons on site will illuminate green when healthy/no alarm, amber on low level alarm and red on upper level alarm.

An oxygen depletion system could be used to activate ventilation to the risk area to ensure an adequate oxygen level.

CDAS is an a1-cbiss own data acquisition & reporting software product which offers full logging of data relating to CO2 & O2 levels and alarm history on a local PC. The PC screen is configured to show a graphical view of each zone, including traffic light coded indication of current status and alarms.
