We are becoming more aware of the limitations of our environ­ment. The Earth’s resources and waste-disposal capabilities are finite. Stricter limitations will be imposed gradually on the amount of pollutant which can be released, while the list of pol­lutants will become longer. The fan user must be aware of the full consequences of leakage of gas from the fan and installa­tion.

The environment can be considered in two separate identities:

• local

• global

If the site is surrounded or close to a town what risk is likely to the population, structures or habitat in the event of a failure? In the global sense, what are the likely cumulative effects of product leakage?
