C.O.S.H.H. reduce harm to environ-ment In order to reduce any harmful effects that may have been experienced by employees, the government introduced C.O.S.H.H. (Control Of Substances Hazardous to Health). The aims of these regulations were to help to: assess risks (risk assessment) collect data analyse data reduce harm to environ-ment make rules and laws reduce harm to workers So working is now cleaner, healthier and less polluting.

Current situation BUT… Accidents still happen. There are oil spills and the rivers and air are polluted because of people ignoring the rules, and equipment failing. And, most importantly, all manufacturing uses energy – electricity has to be generated, raw materials have to be obtained and delivered and the whole process can end up being very damaging to the environment. This is what you have to be aware of when designing and making a product – it is important to think of all the different ways in which you may be affecting the environment, and to make the effort to cause as little harm as possible.

Key points It is important to consider the rest of society and the environment when designing and making a product. Marketing is about attracting attention and making people buy your product. Products can have long or short life cycles, depending on the choice of the manufacturer. This leads to a lot of environmental problems. Early industries also caused many environmental problems, but legislation was introduced to reduce them. There are still a lot of environmental issues today, including the greenhouse effect, acid rain and pollution. It is important to reduce the amount of waste produced and to help the environment as much as possible. Key points 9 of 23 © Boardworks Ltd 2005
