UNIT 4: ENVIRONMENT MANAGEMENT SYSTEMS
Managing ODS in Aerosols and Foams
With aerosols and foams, it is best to switch to zero-ODS alternatives as soon as
current stocks have been used. Zero-ODS alternatives include natural fibre-based
materials to replace foams, and pump-action or refillable spray cans to replace
aerosols.
Examples of Good Practice
At the Steigenberger Kurhaus, Amsterdam, The Netherlands, all refrigeration
systems are CFC-free. Refrigeration experts carried out the disposal of old
equipment, to ensure that no CFCs leaked or evaporated during the process.
The Park Sheraton, Madras, India has installed zero-ODS refrigerators, walk-in
cold rooms and deep-freezers. The CFC-11-based central air-conditioning unit
has also been replaced with zero-ODS alternatives. Aerosol spray cans have
been replaced with pump action sprays. Dry-cleaning machines now operate
on perchlorethylene, which is not an ODS. Foam insulation has been replaced
with natural materials. After working with suppliers and implementing a waste
management plan, styrofoam packaging is no longer used and the use of
styrofoam cups has been discontinued.
The Renaissance Jamaica Grand Resort, Ocho Rios, Jamaica, has replaced the
old chiller with an HFC-134A-operated 350-tonne chiller which brings added
benefits in terms of energy efficiency, 0.50 kw/tonne.
ENVIRONMENT MANAGEMENT PROGRAMME FOR
NOISE MANAGEMENT
Good housekeeping options for noise management
• Ensure all doors are kept closed, especially those in noisy areas;
• Investigate if more regular maintenance will help reduce noise levels
from appliances and equipment;
• Check if changes in operating procedures can help reduce noise
• Require delivery and waste-removal vehicles to switch off their engines
while loading and unloading;
• Use rubber mountings to soundproof isolated machines;
• Work towards eliminating false fire alarms;
• At night, switch off machinery located near guest rooms;
• Ensure that ear protection is worn by employees involved in very
noisy work.

Repair and retrofit options for noise management
• Install quieter motors and fans in equipment;
• Use sound-absorbing devices to enclose entrances to noisy areas and
equipment;
• Install noise-controllers on air-cooling openings;
• Encapsulate machinery with damping materials (e.g. elastic panel
mounting);
• Install reinforced foundations for heavy equipment;
• Install automatic door closing in guest rooms;
