General Requirements
Noise Emission
The noise level produced by the machine will be dependant on;
• the material being cut
• ancillary devices being used (knife heads, drill heads etc)
• attachments to the machine (vacuum pumps, dust collectors, air compressors etc)
• the individual workplace environment.
The appropriate health and safety regulations must be consulted when considering the location
of the machine in the workplace, any sound-proofing or acoustic enclosure to be erected, or the
provision of personal protective equipment (PPE) in the form of hearing protection.
A noise survey and specific risk assessments should be undertaken by a competent person in
each workplace and for each work situation and material being cut, but in general the noise
levels produced by the machine may be found to be in the region of the following readings:
Equivalent continuous A-weighted sound pressure level, LAEQ above 90dB (A) when machining
aluminium.
Equivalent continuous A-weighted sound pressure level, LAEQ above 90dB (A) when machining
medium density fibreboard (MDF).
There is not normally any impulsive noise from the machine.
It is recommended that precautions are taken against injury to machine operators and others
from long-term exposure to noise, either by:
• enclosing the machine in an acoustic enclosure or booth fitted with closing doors
• requiring the operator, and other persons working or having cause to be nearby, to wear
a suitable form of hearing protection.
Suitable mandatory hearing protection signs should be displayed on or adjacent to the acoustic
enclosure or in the zone where the machine is located. The wearing of adequate protective
equipment should be enforced.
Operating Temperatures
The machines are designed to be operated between temperatures of -5
o
C and +40
o
C.
During operation machine components such as spindles, vacuum pumps and cutting tools will
become hot. Care must me exercised when coming in to contact with these or any other items
likely to become affected by heat.
Vacuum Pumps:
Vacuum pumps expel hot air at high velocity. Adequate provision must be made to allow
for the safe and unrestricted expulsion of the exhaust air. DO NOT
• block the exhaust manifold
• place objects in close proximity to the exhaust air
• place vacuum pumps in confined spaces
• touch the surface of the vacuum pump as it will become hot during operation
resulting in burns and scalding
