5. The IARC International Agency for Research into Cancer after researching nasal cancer among woodworkers in Europe has classified wood dust a human carcinogen Wood dust from timbers such as beech and oak which is fine enough to be inhaled is known to cause cancer Other species such as birch mahogany teak and walnut may also be capable of causing nasal cancer As this is a rare form of cancer the risk is small and generally restricted to the finishing trades where the dust is fine Freshly cut trees contain large amounts of microbes mainly moulds The number of these increases if the logs are stored outside and under moist or humid conditions The microbes can cause inflammation of the airways during debarking sawing and transportation What About Different Woods r While there has been considerable research carried out on European and North American species relatively little is known about the way dusts from different Australian timbers affect people s health Each type of timber has its own chemical components and may affect people differently Even less is known about dusts from imported woods for example from Africa South America and Asia There is a concern that adverse health effects from some of these wood dusts may not show up for perhaps many years Protection for workers today is therefore vitally important What About Chemicals Plywoods fibre boards particle boards and laminated products contain formaldehyde t
6. IDENTIFYING HAZARDS AND MANAGING RISKS IN DESIGN AND TECHNOLOGY 1 BACKGROUND Design and Technology activities present one of the highest levels of risk for injury to staff and students Therefore it is essential that the hazards associated with each activity are identified and the risk of injury assessed and minimised The requirement to identify assess and control the risks in Design and Technology is based primarily on the Occupational Safety and Health Act 1984 OSH and Occupational Safety and Health Regulations 1996 Employers must ensure that employees and visitors are not exposed to hazards and that the risks associated with identified hazards are assessed and controlled This document provides information on hazards that can be found in various Design and Technology activities and provides instructions and advice on how the risk of injury can be minimised and controlled This document also contains the working policies operating in Design and Technology at St Mark s Anglican Community School Acknowledgement This document is based on manuals from Queensland Catholic Education and the Queensland Department of Education and has been developed through a process of consultation with the Design and Technology Teachers Association DATTA the Australian Education Union WA Branch and Design and Technology teachers at St Mark s ACS 2 DEFINITIONS Hazard a condition or situation that has the capacity to harm people plant or buildi
7. Likelihood or probability of a particular consequence occurring The likelihood is scaled in five levels ranging from very likely where the risk would almost certainly occur to highly unlikely where risks would be more likely in exceptional circumstances only When assessing the likelihood of someone being exposed to a hazard the frequency of that exposure also should be considered 2 The Consequences the possible consequences of each particular hazard of an activity as identified in Step 1 The most likely or typical consequences resulting from exposure to a particular hazard need to be determined Consequences range from negligible through to major where serious injury is likely to happen Existing Controls Controls that currently exist are also taken into consideration when determining the level of risk For example an existing control may be a process that has been developed to ensure people are not r exposed to the hazard i e rules requiring the fixing of work or guards placed to prevent exposure to possible moving or hot objects The procedure to assess risk in the St Mark s workshops is governed by the Risk Matrix The risk matrix is used to assess the level of identified risks and prioritise actions to reduce them In order to use the matrix 1 Identify the likelihood of exposure to the hazard and the consequence of someone being exposed in the left hand column 2 Go across the row of the likelihood identi

MSDS Registers Registers will be located in the following areas Design amp Technology Office Administration Office MSDS sheets will be displayed At location of use Storage areas AS part of the Policy staff are trained on correct use of all hazardous materials B MACHINERY EQUIPMENT AND GUARDING 1 BACKGROUND The purpose of machine guarding is to prevent contact between people and the hazards of equipment and machinery such as moving parts and hot surfaces The hierarchy of control see Section 1 Appendix 1 is used to identify control measures for any kind of risk Machine guarding by its nature is not the most effective control measure but often it is the most practicable Note elimination of a hazard is the most effective because the hazard is eliminated completely while wearing personal protective equipment is the least effective because the hazard still exists in its original capacity New items of machinery should be adequately guarded according to the relevant Australian Standards However some imported machinery does not comply Also many items are relatively old and may not ever have been adequately guarded or have been modified by people wishing to make the machine easier to use The risk management process can ensure that risk associated with hazards of inadequate guarding is controlled effectively 1 1 Potential Hazards The hazards associated with machinery and guarding include Parts whic
