Portable Power Router Safety
1     Background
1.1    The article below was obtained from WorkCover Tasmania website. 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
       During the machiningp o e step ro ’ f g r itec t r n wa b dy e
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.

Falls Prevention - Above Ground Fuel Tanks
1     Background
1.1    Risk controls must be in place for tasks that may expose people to the risk of
       falling from an above ground fuel tank when undertaking such tasks as filling the
       fuel tank, dispensing fuel or checking on fuel levels.

2     Risk controls
2.1    The most effective solution to reduce the risk of falling from a fuel tank is to perform
       the tasks of filling the fuel tank, dispensing fuel and checking on fuel levels at the
       ground level. 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.

          Figure 2
          Example of a fuel tank fitted with ladder and platform constructed to
          Australian Standard 1657 - 1992 Fixed platforms, walkways, stairways
          and ladders –design, construction and installation.

Maintenance of Guards
1     Background
1.1    The following article, published on the Western Australian Department of Consumer
       and Employment Protection website serves to highlight the importance of undertaking
       routine machine maintenance.
1.2    The defendant was convicted at Perth Court of Petty Sessions and fined $1500 for
       failing to ensure, as far as was practicable, that a guard was kept in position while the
       plant was operated.

2     Details
2.1    Between 1 September 2002 and approximately 23 October 2002 the guard on an
       Omega drop saw was not functioning properly. The grub screw that secures the
        u r ’ o to r d de am            s s n n h ur
       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
       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.

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.

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.
