UNIT 4: ENVIRONMENT MANAGEMENT SYSTEMS<br />
in areas near busy garages and roads report dizziness, it could be caused by<br />
continued exposure to higher levels of carbon monoxide and carbon dioxide.<br />
Examples of Good Practice<br />
The Tampere Hall Concert and Conference Centre, Tampere, Finland, adjusts<br />
air-conditioning during concerts and meetings according to load levels. Staff<br />
responsible for air-conditioning circulate in the halls with carbon dioxide meters<br />
and increase or decrease air-conditioning as required.<br />
At the Maurya Sheraton Hotel and Towers, New Delhi, India, ‘ozoniers’ are<br />
installed in guest rooms to improve indoor air quality. These devices (sometimes<br />
referred to as ‘aranisers’) energise the oxygen in the air. Energised oxygen<br />
accelerates the breakdown of odours, pollutants and many other harmful<br />
substances.<br />
COMMON QUESTION What is an araniser?<br />
Air is purified naturally in several ways. The most frequent is during a<br />
thunderstorm, when the build-up of energy before a lightening strike charges<br />
the oxygen in the air. The charged oxygen reacts with contaminants in the air<br />
and destroys them. This process is partly why the air smells so clean and fresh<br />
after a storm.<br />
An araniser creates an energy corona, a simulation of the natural phenomenon.<br />
It selectively separates the molecules of oxygen in the surrounding atmosphere<br />
and regroups them into ‘free’ nascent atoms of oxygen. These groupings have<br />
more power to combat pollutants.<br />

• Refrigerators, freezers including cold display cabinets, mini-bars, ice<br />
and vending machines, in which CFC-11, CFC-12 and CFC-114 may be<br />
used as refrigerants;<br />
• Air-conditioning in buildings and vehicles in which CFC-11 and CFC-12<br />
may be used as refrigerants;<br />
• Dry-cleaning equipment which uses CFC-113 and methyl chloroform;<br />
• CFC-11, CFC-12, CFC-113, and CFC-114 are used as blowing agents in<br />
the manufacture of plastic foams. Foams are used in hospitality for<br />
packaging, upholstery, pipe insulation, cushions, car interiors and<br />
carpet underlay;<br />
• Halon-1211, Halon-2402 and Halon-1301 are used in fixed and portable<br />
fire extinguishers.<br />
ODS Management in Refrigerators and Freezers<br />
Discontinuing the use of ODS in refrigeration includes containment, recycling,<br />
retrofitting, and replacement.<br />
• Containment means regular maintenance to prevent refrigerant<br />
leakage and thereby avoid the need to recharge or ‘top-up’ the system;
