Hazards‚ risks‚ outcomes The terminology used in OSH varies between states‚ but generally speaking: • A hazard is something that can cause harm if not controlled. • The outcome is the harm that results from an uncontrolled hazard. • A risk is a combination of the probability that a particular outcome will occur and the severity of the harm involved. “Hazard”‚ “risk”‚ and “outcome” are used in other fields to describe e.g. environmental damage‚ or damage to equipment. However‚ in

Environmental Hazards Kenya Lewis Environmental science Instructor: Donald Demoulin Everest University June 11‚ 2011 What are the four categories of human environmental hazards? Culture Hazards are a person risky choice of their lifestyle. People engage in risky behavior and subject themselves to hazards. They may smoke cigarettes‚ eat too much‚ drive too fast‚ use addictive and harmful drugs‚ consume alcoholic beverage‚ sunbathe‚ engage in risky sexual practices‚ get too little exercise

Natural Hazards and Natural Disasters A natural hazard is a threat of a naturally occurring event will have a negative effect on humans. This negative effect is what we call a natural disaster. In other words when the hazardous threat actually happens and harms humans‚ we call the event a natural disaster. Natural Hazards (and the resulting disasters) are the result of naturally occurring processes that have operated throughout Earth’s history. Effects of Hazards Hazardous process of all

What is a hazard? A Hazard is any existing or potential condition which by itself or by interaction with other variables (physical/ biological) can results in death‚ injury or chemical damage to persons‚ property‚ the environment and information. There are five main types of hazards that exist everywhere‚ They are chemical‚ physical‚ biological‚ ergonomical and psychosocial.

Seismic hazards have many different impacts around the world. An earthquake took place in Haiti 2010 and it was measured 7 on the Richter scale. The main hazard was the seismic waves caused by shifting rocks in an earthquake. There are two main types of waves‚ P waves and S waves. P waves travel through solids and liquids around 6-7 km/h and parallel through the rocks. S ways travel side ways at 2.5-4km/h and can only get through solids. Both waves can have a big impact on the community‚ a lot of

SCIENCE HOMEWORK By Mahamed.A Level 3 A hazard is a symbol that tells when something is dangerous. There could be a symbol when you are in a science lab an example of this is a hazard symbol stating that there is acids in the laboratory .There are lots of different symbols used to warn people about lots of different things. If there is a hazard symbol telling you not to do it then don’t because it is very likely that you will get hurt especially if acid goes into your skin. Level 3 (continued)

Prepare motor transport equipment for cargo. Determining the dimensions of a load is important because it will determine the type of vehicle that will be used and what cannot be used. When figuring out how much space is needed it is useful to have a tape measure for all non-standard items. The weight of a load can

Natural Hazards – Bushfires A natural hazard is a natural event that has a significantly negative effect on people or the environment. Many natural hazards are related. For example drought can lead to famine and earthquakes can form tsunamis and landslides. Australia’s most common natural hazards are storms‚ cyclones‚ floods‚ droughts‚ heatwaves and bushfires. Natural Hazards have a major impact on Australian communities including loss of life‚ property damage‚ environmental destruction‚ and a

Lava This presentation will discuss two questions which are How is Lava Produced? And What hazards/dangers does lava pose? It will also study one example of a Lava Flow in Hawaii. Lava is molten rock expelled by a volcano during erupting. It is produced/ formed in the interior of planets including Earth and their satellites. When the lava is first erupted from the vent in a volcano otherwise known as the volcanic vent‚ lava is a liquid and varies from 700°C to 1‚200°C. Although lava is
