Buy only CFC-free aerosols. Avoid buying food and drinks in styrofoam containers, e.g. coffee, tea, salads, meat, fruit, fast-food. As far as possible avoid items with styrofoam packaging. Carry out a survey of your home,school or office to see what CFC products are being used and how they can be substituted. If your family is buying a refrigerator choose one which is more ozone friendly and which can be serviced without any coolant gas being released into the air.
Most manufacturers supply the information needed to make a wise choice.
Also try to make sure that there are arrangements for the coolant gases to be removed from the old refrigerator before it is broken up. Enfo - The Environmental Information Service, Briefing Sheet 25.
