Safety Warnings - Loma IQ3 User Manual

Safety Warnings

Listed below are the safety warnings that are applicable when using a Loma metal detector. It is
strongly recommended that personnel who are, or will be, responsible for installing, maintaining or
operating the equipment described in this manual should read and understand these warnings.
Systems manufactured by Loma are specifically designed for Automatic in-line operation. Operators
are normally only required to work on the machine intermittently and this interaction is usually limited
to either changing product settings via the system control panel or emptying product from the reject
receptacle.
Engineers involved in installation, servicing and maintenance of the metal detector may be exposed to
hazards in the execution of particular actions so are advised to be particularly vigilant and take into
account the potential hazards listed.
1. LETHAL HAZARD – ELECTRICAL SUPPLIES. A current of 100 milliamps passing through the
body for one second can kill. This can occur at voltages as low as 35V ac or 50V dc The
equipment described in this manual uses electrical power which can be lethal. Unless absolutely
necessary, cleaning, inspection and maintenance must not be carried out without first isolating
the equipment from all electrical supplies.
2. LETHAL HAZARD – COMPRESSED AIR SUPPLIES. The equipment described in this manual
may be supplied with a compressed air supply operating at a pressure which may be lethal.
Unless absolutely necessary, cleaning, inspection and maintenance must not be carried out
without first isolating the equipment from all compressed air supplies.
3. NON-IONIZING RADIATION. Loma metal detectors employ low intensity electromagnetic fields in
compliance with current legislation. If used in close proximity to an electromagnetic field, the
operation of pacemakers, cardiac defibrillators and other life support devices can be affected.
Wearers of these devices should therefore consult their doctor for advice on avoiding this hazard.
4. WORKING ON EQUIPMENT. If it is essential to work on the equipment with electrical and/or
compressed air power connected, the work must be undertaken only by qualified personnel who
are fully aware of the danger involved and who have taken adequate safety precautions to avoid
contact with dangerous voltages and/or compressed air supplies. Before disconnecting the metal
detector from power, removing the power plug or loosening the power terminals ensure that
signal cables to other machines are disconnected first. Take care not to trap the earth wire or
ribbon cable when closing the enclosure lid.
5. REJECT DEVICES. At no time, with compressed air and/or electrical power applied to an
automatic reject device, should any part of the body be placed within the operating area of the
reject device.
6. EXCESSIVE NOISE. When an air blast reject device operates, the noise emitted may constitute a
noise hazard. While short exposure to this noise will not cause permanent damage to hearing,
prolonged exposure may cause some damage. It is recommended that ear defenders are worn
by personnel who are regularly exposed to the noise.
7. HEAVY EQUIPMENT. Loma metal detectors are extremely heavy and considerable care must be
taken when handling them. Sufficient personnel and a suitable fork-lift truck or pallet truck must
be used to ensure safe handling.
8. LIFTING THE MACHINE. Use only the correct slings and lifting tackle to move Loma metal
detectors. Visually inspect all slings and lifting tackle prior to lifting the machine to ensure that:
a. The safe working load will not be exceeded.
b. There are no frayed or broken strands.
c. Hooks, rings, etc. are not damaged.
9. MOVING THE MACHINE. The centre of gravity of some metal detectors is high. Lower the height
adjustment to its minimum before moving. Care must be taken when moving a metal detector on
a slope to ensure that it does not topple over. This could result in death or severe injury to an
individual and/or severe damage to the equipment.
