While it refers to an incident, which occurred in 2002 in Tasmania, it remains highly relevant for DECS environments where Portable Power Routers are used. Figure 1 Example of the incorrect use of a portable router 2 Details 2.1 A person was using a plunge router to rebate and bevel a 25 X 15 mm piece of timber, 300mm long. The router was inverted and clamped in a vice. In this position the router becomes a small, unguarded spindle moulder. 2.2 r c s h es ns i e ht h ut a d s a l n During the machiningp o e step ro ’ f g r itec t r n wa b dy e lacerated. 2.3 The operator had some experience with the use of hand power tools, including the router involved. 3 Contributing factors 3.1 An investigation into this accident revealed that: The hand held router was not being used as intended by the manufacturer. The router was inverted and clamped in a vice. The cutter was not guarded when used in this way. The table was too small to allow the safe operation of jigs or other aids. The machining of a small, short length of timber without guarding or the use of jigs brings hands and fingers close to the unprotected cutter. 4 Recommendations 4.1 The router is a power tool designed to be held with both hands and moved along a work piece when in use. 4.2 If inverted, the router must be fixed into a purpose designed router table with the required fences, dust extraction and guarding. 4.3 When machining small sections of timber, jigs, clamps and other aids, –which prevent bodily contact with the cutter –must be used. 5 Acknowledgement 5.1 The following document has been used in the compilation of this article and further information can be obtained from it.

This can be achieved by: Relocating or installing the fuel tank to ground level and dispensing fuel with the aid of a pump. Installing external fuel gauges to avoid having to climb to determine the level of fuel in the fuel tank. 2.2 Ensure any modifications to the fuel tank maintain the intrinsic safety of the tank and are undertaken by a suitably qualified person using a safe work permit system. 2.3 If it is not practicable for the tasks of filling the fuel tank, dispensing fuel and checking on fuel levels to be performed at the ground level, then ensure that a permanently secured access ladder which complies with Australian Standard 1657 is installed to the fuel tank. 2.4 AS 1657 specifies that: The access ladder has handrails at least 900mm above the work platform. The work platform at the top of the ladder has a minimum width of 600mm and depth of 900mm and has toe boards and a mid rail at 450mm.

The grub screw that secures the u r ’ o to r d de am s s n n h ur s g adsc nr l o ilr r wa mi iga dteg adwa h l i pa eb ape e s ed n lc y ic of wire. 2.2 In order for the guard to function normally the grub screw was required to be in place allowing the guard to cover the blade until the saw was brought downwards in order to cut the work piece. During the cutting process the guard automatically retracts to expose the blade enabling the cut to be performed. 2.3 With the grub screw missing, the guard covered the blade and was not retractable; therefore making the drop saw inoperable. In order to operate the saw, the guard was retracted and held in position with a piece of wire so that the blade was exposed at all times. 2.4 On 22 or 23 of October 2002 an employee of the defendant was using the Omega drop saw when the piece of wire broke causing the guard to drop down onto the material, which was being cut. The employee reported this to the foreman. The broken wire was replaced as a temporary measure to finish the job. On completion the grub screw was replaced which allowed the guard to return to its normal safe operating position. 2.5 The ease with which the wire was replaced with a grub screw indicates that it was practicable for the defendant to ensure that the guard was kept in position by using a r b ce ah r h n ic f r o e u e h u r ’ o to r d de am. t e g u s rw rte ta ape eo wi t s c r teg adsc nr l o ilr r I was practicable for the defendant to have had systems in place for inspecting the guard at regular intervals to ensure that it was operating correctly, and it was practicable for the defendant to have a system in place requiring employees to report any problem with a guard of plant. 3 Recommendations 3.1 Machines with malfunctioning guarding must be tagged and locked out until repairs or replacement are carried out. 3.2 Routine inspection and maintenance must be undertaken and documented. 4 Acknowledgement 4.1 The following document has been used in the compilation of this article and further information can be obtained from it.

Database Update 1 Background 1.1 In 2002 the department organised a comprehensive inventory of all machinery in the technology studies, agricultural studies and grounds areas resulting in the formation of an database. This database has proved valuable when developing strategies and monitoring high risk plant and equipment in DECS sites. 1.2 DECS is seeking the support of sites to update the database biannually. 2 Action required 2.1 During this term sites should receive a report of their Design & Technology and Agriculture Studies & Grounds machinery and equipment based on the 2002 audit and any disposal/ acquisition notices received. 4 February 2005 2.2 Site managers are requested to review the status of this machinery and equipment report and, where necessary, modify the records. 2.3 Please forward any amendments to David Large, 12th Floor, Education Centre, 31 Flinders Street, Adelaide, 5000, Courier R11/7 by Friday 15 April 2005. If there is no change, a no change report should also be forwarded to the same address. An updated copy will be forwarded to sites in due course for site records. If further information is required, please contact David Large: tel. 8226 7630. Vehicle Service Pits 1 Background 1.1 There are risks of serious injury to persons working in or near vehicle service pits by asphyxiation, explosion or fire (should any flammable gases or vapours contact an ignition source), falling into an unguarded open pit, being struck by an accidentally dropped item of equipment and the inability to escape in an emergency (fire). 1.2 Risks of using pits in schools are greater than a normal workshop due to the increased number of persons (students) working in the area. 2 Risk control 2.1 Eliminate the pit and replace with a multipurpose hoist or elevated ramps. These are subject to risk assessments and specific safety requirements. 2.2 If a pit must be used cover unused sections of the pit with stout hardwood boards. 2.3 While the cover is not in place, the pit must be constantly attended by someone or be protected on all exposed sides by removable standard railings. Sectionalised guard railing, designed to slip into prepared floor sockets, to prevent the unwary from walking into exposed pits should be considered in addition to hardwood boards. 2.4 Safety is improved further if the pit interior is painted white and the edges are outlined for at least 300mm by diagonal black and yellow stripes approximately 100mm wide. 2.5 Pits require fixed means of access built to Australian Standard 1657 Fixed platforms, walkways, stairways and ladders –design, construction and installation. 2.6 All portable and permanent lighting and/or electrical equipment located within the hazardous zone of the pit must be intrinsically safe and must comply with the requirements of Australian Standards 3000 SAA Wiring Rules and AS 2430.1 Classification of Hazardous Areas. 2.7 Routine inspection and maintenance must be undertaken at least every 3 months. 3 Working in a vehicle service pit 3.1 Apart from the above risk controls the following safe systems of work should always be considered before entering a vehicle service pit: Check pit for presence of flammable or other hazardous vapours. Ensure natural airflow through the workshop to reduce concentrations of the vapours and/or gases. Place vehicle so there is room to get out of pit in an emergency. Set chocks to keep vehicle from moving. Use pneumatic (air-powered) or explosion-protected tools as a safety precaution even though the pit has been checked for flammable vapours. Do not drain a fuel tank over or near a pit. Vapours from fuel are heavier than air. Welding and oxy cutting from a pit are extremely dangerous operations and must not be carried out unless the pit has been completely purged of oil flammable vapour and gases. Do not jump across pits. 4 Acknowledgements 4.1 The following documents have been used in the compilation of this article and further information can be obtained from them. Workplace Services.
