Safety First

Caution: Pinch Point
Moving parts of machines, specifically conveyors, provide
opportunities for trapping fingers or even items of clothing in
the mechanism if care is not taken.
Caution: Isolate Machine Before Maintenance
Electrical power should be disconnected before carrying out
maintenance operations that expose staff to potentially
lethal voltages.
Caution: Isolate air supply before maintenance
Compressed air should be disconnected before carrying out
maintenance operations where reject devices could be
activated accidentally.
Safety Guards
Under no circumstance must a machine be operated with any guarding removed or interlock
switches defeated.
Guarding
For Loma metal detectors the use of guarding, including covers, panels, curtains and other methods
is extremely important in order to restrict operators from accessing areas of the machine that are
potentially hazardous whilst the machine is operating or to prevent exposure to potentially hazardous
ionising and non-ionising radiation.
Interlock switches
On some machines, access hatches are incorporated into the guards to provide access to some
areas of the machine to, for example, clear obstructions and remove products when required. These
hatches are fitted with an interlock switch so that when a hatch is opened, the machine will switch off
and a fault condition is generated.
Safety Relay and Circuits
As safety is paramount, at least one fail safe relay is fitted to ensure that if a contact of the interlocks
were to fail the safety relay will automatically detect the fault and therefore switch off the metal
detector and generate a fault condition.
