Question 1)

What is Occupational Health and Safety?

Occupational Health and Safety (OHS) which refers to the legislation, policies, proceedures and activities aims; to protect the health, safety and welfare of all people in the workplace. Every worker has the right to working conditons that are healthy and safe. This enables them to live a life that is socially and economically productive.

OHS is concerned with workplace safety and the injuries and diseases that have a major impact on the work environment. Their are many physical, chemical, biological, psychosocial or organisatonal hazards that can cause injury, death or disease in the workplace.

In Australia, the annual cost of associated ill health is between $15-37 bilion every year. Internationally, two new cases are reported each minute, bringing more harm to the global community than from road accidents, war, violence and HIV/AIDS combined. Health and Safety profesionals work first to prevent, then minimise the incidence and impact of workplace hazards.

Question 2)

Read the following text on Global warming and according to the text select the most correct answer.

Global Warming

Over the last century, the average temperature of the air near the Earth's surface has risen to just under 1° Celsius. Experts on the Intergovernmental Panel on Climate Change, whose role it is to evaluate the risk of environmental change, report that the increase in temperature is mainly due to an increase in greenhouse gas emissions as a result of burning fossil fuels. The other culprit is deforestation.

The greenhouse effect is a natural warming process. Carbon dioxide (CO₂) and other gases are always present in the atmosphere. These gases create a warming effect similar to the warming inside a greenhouse. If the amount of greenhouse gases increase, the greenhouse effect is intensified. Higher concentrations of CO₂ and other greenhouse gases trap more infrared energy in the atmosphere than occurs naturally. This added heat warms the atmosphere and Earth's surface and will cause the Earth to continue warming.

Carbon dioxide levels are increasing because the natural system cannot keep up with the new emissions. The natural processes that remove this additional carbon, for example ocean uptake and sedimentation, work very slowly. Compared to the rate at which we are adding CO₂ to the atmosphere, the natural changes to the carbon cycle are taking a long time to balance out. The redistribution of the added CO₂ between the atmosphere, oceans, and biosphere takes hundreds of years, and the removal of the added carbon from the short-term cycle by the long-term cycle takes thousands of years.

The obvious concern is about the rate at which the earth is warming. Scientific evidence suggests that there has always been a natural climate change, for example from the Ice Age to the warmer times in between this period. However this occurred over a period of 50,000 to 100,000 years. There is a major concern that the temperature will continue to rise even after carbon emissions cease, due to carbon dioxide concentrations in the atmosphere that are closely related to temperature fluctuations.

Why is this of concern? An increase in global temperature will cause sea levels to rise. Water expands as it warms. Therefore, the sea level will rise as the top few hundred metres of the oceans warm and swell. Melting water from polar glaciers is another source of sea level rise. The impacts of rising sea level include flooding of cities, loss of coastal ecosystems, displacement of coastal inhabitants as coast-lines would not be suitable for living because of the sea level and increased vulnerability to storm surges. Due to the rising temperature of our oceans the plants and animals which cannot tolerate the heat would die.

There is another concern over ice polar caps melting. Polar caps reflect sunlight, therefore if our polar caps keep melting; it would add more heat to our oceans and land instead of helping to regulate them. Without polar caps, the sun would be adding heat to the already tenuous situation. Some say that ice caps melt as part of the regular heating and cooling cycles of the Earth, therefore it is not of major concern. Research suggests otherwise, however.

Global warming will also affect human health. The malaria mosquito could move to other regions of the world where it is currently too cold to survive and breed. This could have catastrophic effects. Heat-related illnesses may rise in the hotter summers, and breathing problems could increase as higher temperatures increase air pollution in cities, thus reducing air quality. More extreme weather, for example storms, floods and droughts will have severe impacts on the environment and on society. The poorest people in the world will not be able to cope with the impacts of global warming.

Government and public debate continues in relation to climate change, as well as discussions over what actions we need to take in order to reduce our impact on the environment. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.

Means, so as to help reduce these adverse impacts Therefore, it is important For everyone to consider which trips could be made by other means, so as to help reduce these adverse impacts therefore, it is important for everyone to consider which trips could be made by other means, so as to help reduce these adverse impacts. therefore, it is important. for everyone to consider which trips could be made by other.

Sentence

Their car all day, quite Often in a location some distance from their work place Many people drive to work and park their car all day, quite often in a location some distance from their work place many people drive to work and park their car all day, quite. often in a location some distance from their work place. many people drive to work and park.

They don't need their car at work. For these people, public transport may be an attractive alternative. They may walk to the local station or bus stop, or drive to a commuter parking area. Catching public transport can be cheaper than driving. It will not be driven long distances everyday And maintenance costs, because there will be less wear and tear on your car, as It can save on fuel costs, parking costs it will not be driven long distances everyday and maintenance costs, because there will be less wear and tear on your car, as it can save on fuel costs, parking costs it will not be driven long distances everyday. and maintenance costs, because there will be less wear and tear on your car, as. it can save on fuel costs, parking costs.
