Safety Warnings - Loma IQ3+ST 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. Modular belts when run at
higher speeds (typically above 50 m/min) can also generate noise levels in excess of
70dB(A). 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
