HEALTH AND SAFETY

The CE mark on this maehillC signifies that an EC dedaration of oonformily is drawn up indicating that the machine ia manufactured in accordance with the Essential Health and Safety Requirements of the 'Supply of Machinery (Safely) Regulations 1992.'

The 'requirements 101 supply of relevent machinery' in the General Requirement 01 the Reguletions are not only that the machine satlslies the relevant assentla l health and safety requi rements, Dut also that 'the manulacture ..... carries out the necessary research or lests on components, fittings or the complete machine 10 determine wh(lth\!r by its design or construction Ih\! machine is capabts of bslng erected and put Into service safely.'

PGr sons who install this machine have duties under Ihe 'Provision and Use 01 Work Equipment Regulations 1992'. An indication o f these duties Is given In the following extracts, but lt1e user should be familiar with the lull Implications ollhe regulations.

REGULATION 5 requires that;

Every employer shall ensure Ihat work equipment is 50 constrocted Of adapted as to be suitable for the purpose lor which it is used or provided.

In selecting work equipment, every employer shall heve regard to the working conditions and to the risks to heallh end safety 01 persons whleh exist in Iho promi"o" or undertakings in which tha\ work equipment is to be used and any additional risk posed by the USII of that work equipment.

Every employer shall ensure that work equipment is used only for the operations lor which, and under conditions lor which, it is suitable.

In lhls regulation 'suitabte' means suitable in any respect whi(:h it is reasonab ly foreseaable will affect health or safely of any person.

Tho Provision and Uso 01 Work Equipment Regulations also indude requirements as follows:

regulation 6 · malntell3.noo

regulation 7 - specific risks

regulaMn a - information and insttuc~ons

regulation 9 - train ing

Note:-

Attention is drawn 10 those requirements of the 'Woodworking Machines Regulations 1974' which are 1"101 replaced by the Supply of Machln ~ry (Safety) Re9ulations or oth~r, ~.g.: Regulation 13 of the Wooctworking Machinery Rsgulation, - 'Training', still appj ies.

Whilst the prime duly for Bf1suring health and safely res ts with emptoyers, employoes too have legal duties, particularly under sections 7 and a of the Health and Safety at Work Act. They Include:

Tak ing reasonabl~ CSr8 for their own heallh and safety and that 01 others who may be affected by what they do or don't do;

co-operating with Iheir employer on health and safely:

nol interfering with Of misusing anything provided for their health, safely and welfare.

Those dutie6 on employaes have been supple mented by rogu la\ion 12 ot the Management of Health and Safely at Work Regu lalions '992. One 01 the new raquirements is that employees should use correctly all work items provided by the ir employer in accordance with their training and Ihe Instructions they receive to enabte them to use the items safely.

Noise

Noise levels can vary widely lrom machine to machine depending 0fI the condilions 01 use. Persons e~po5ed 10 high noise levels, even for a short time, may e~perience lemporary paftial hearing loss and continuous e~posure to high levels can result in permanent hearing damage.

The Noi~e at Work RegulatiOns 19139 piece legal oolies on employers to prevent damage to hearing.

There are three action levels Of noise delined in regulatiOfl 2:

The first action lowl:·

a daily personal noise e~posure (LEP'd) of 85dB(A)

The second action level;·

a daily personal noise exposure (LEP'd) 01 9()(jB(A)

The peak action level:·

A peak sound pressure of 200 pascals (14006 re 2Opa)

The exposure level is obviously influenced by the emission level of all the equipment in use,

Emissions levels fOl machines are provided in the particular madline instruction manual.

These levels are measured in accordallce with ISO 7960 under certain speclflea test conditions, they do not necessarily represent the hlghesl noise level, which is influenced by many !actors, e,g. number ot epindles in operalion, type and condition of work piece, spindle speeds etc.

For regu lations and information on re levant personal protective equipment i. e. ear defenders, employers should reler to the Persona l Protective Equipment al Work Regulations 1992.

Dus t

Wood dust can be harmful to hea lth by inhalati on and skin contact and cOrlcentratlons cf small particles in the air can form an explosive mixture.

The COlltrol 01 Substances Hal:ardous to Heatth Regulations (COSHH) 1989 place legal duties on employers to ensure that:-

the exposure of his employees to SUbSIElnces hazardous to health is either prevented Of, where this is flOt reasonably prac ticable, adequately controlled.

.. .. adequate control to e~posure of employees to a sub$tance hazardous to health Shall be secured by measures other than the provision of personal protective equipment.

where the measures taken in accordance with the para9raph above do not prevant or provide adequate contro l of, exposure to substances hal:ardous to tile health of emptoyees, then In addition to tacking those mothods, tho employor shall provide thoso emp loyees with suc h suitab le personal protective equipment as will adequately control their exposure to substances hazardous to health.

Inst r uclfons for Use

Machinery manufactures ele required by tile Supply of Machinery Safety Regulations to provide eomprehensive 'Instruct ions for Use" of equipment, it is important that this Information Is transmitted to the person using the machine.

LUBRICATION

It Is advisable to keep a~ bright parts covered with a thin lilm of oil to prevent rlJ$ting.

The slide rods and rol lers should also be kept clear of any sawdust and chippings for ease of operation.

Type 01 oil recommended: POWER EM.125

Type 01 grease recommended: SHELL ALVANIA 3

"'. FOUNDATION

See Fig. 5 for bolt positions and clearance requ ired. When installing, the machine must be levelled ... p by means of packing pieces under the feet. The machine tab le sho ... td be slightly high at the front end. This will ensure thAt the saw ... n~ remains in the back position when not in use (see page 14).

This does not affect the accuracy of the machine.

Foundation bolts are not supplied with the machine except by speCial Order.

NOISE EMISSION VALUES

Machine criteria

The machine was free standing on a concrete f loor, not boiled down and not mounted on any vibration dampening,

A flexible pipe connected the mact1ine to the dust extraction.

There was no enclosure around the mact1ine.

Machine cunlng criteria

The machine was fitted with a 400mm main saw rotating at 3000 rpm. The saw blade had 48 carb ide tipped teeth and a cutting width of 3,2mm, The blade thickness was 2.2mm.

Feed rate: 4·8 Mlmin Saw blade projection: 30mm

Material criteria

The figures quo led in the noise emission chart are emission levels and are nO! necessarily safe working levels,

Whilst there is a correlation between emission levels and e){posure levels. this cannot be I.lsed reliably 10 determine whether er net furlher precautions are required 10 achieve sElle working levels.

Facters that illfluence the Elctual leyel of exposure 10 the werk 10lce include the duration of ~posure, Ihe characteristics of the work room, sources ef noise etc, i.e, the number of machines and other adjacent prrn;esses. Also the parmissible axposu,e lavels can vary from country to COl.lntry,

Emissien levels, however, will enable the user of the mact1 ine to make a beller evaluation of the 'hazard and risk'.

Tooling criteria

The BRA crosscut saws have been designed to accept 350mm or 400mm diameter saw blades Suitable to sit on a 30mm splndte. The saw should ha~ a 'pin hole' location.

Never exceed the specified ma~imum speed of the saw blades.
