5 Safety requirements and/or protective measures
5.1 General
Shearer loaders and plough systems shall comply with the safety requirements and/or protective
measures of this clause.
In addition, they shall be designed according to the principles of ISO 12100 for relevant but not
significant hazards which are not dealt with by this document.
5.2 Contact surfaces
5.2.1 Sharp corners and edges
Accessible parts of the machines shall be designed and manufactured to minimize sharp edges, angles
or rough surfaces which are likely to cause injury, see ISO 12508.
ISO 19225:2017(E)
5.2.2 Hot surfaces
Where there is a risk of contact with hot surfaces in accessible areas, suitable measures shall be taken
in accordance with ISO 13732-1.
This requirement does not apply to the excavation tools.
5.3 Stability
The manufacturer shall specify limit values for the permissible tilting of the machines in all directions.
This is to avoid possible instability of the shearer during operation or while standing, which could cause
injury to personnel within the area of the machine.
To evaluate the stability of shearer loaders, the forces acting on the two cutting drums and the weight
of the machine simplified in the transverse plane to the machine are taken into account (see Figure 3).
The size of the forces and their directions as well as the distance to the bearing points A + B shall be
determined by the manufacturer.
At least one of the bearing points A + B shall be designed as a form-fit bearing to absorb vertical as well
as horizontal forces.
The maximum permissible inclination of the machine in longitudinal and transverse direction has to be
determined by the manufacturer and indicated in the operating manual.

The coal plough (see Figure 4) runs on a special guidance, lying along the longwall face and attached to
the armoured face conveyor pans.
In that way plough bodies are restraint-guided with one degree of freedom aligned in the face direction.
Through the compulsory guide a plough body cannot leave the guidance, even in case of very high loads
acting on that body.
In situations where the plough body is decisively higher than the plough body guidance, the use of
additional stabilizers might be necessary.

5.4 Control devices and systems
5.4.1 General requirements
Control devices and systems shall be designed and built to meet the high demands of an underground
environment and to be reliable in service.
They shall be able to withstand shock loads of 15 g/11 ms, along with ambient air temperatures of up to
40 °C, and up to 100 % humidity.
ISO 19225:2017(E)
Control devices shall meet the requirements of ISO 9355-1. They shall be set out clearly and designed
so that they can be actuated easily and safely by the operator even when wearing gloves. Pushbuttons
on hand-held devices shall be at least 14 mm in diameter and the distance between buttons shall be at
least 3 mm.
The direction of movement and control effect of the control devices shall be logical. Control devices
shall be permanently and unambiguously marked.
The colour coding as specified in IEC 61310-1 shall be used for control devices and displays.
Control devices for ranging arms, lump breaker, cowls and sloughing covers shall be designed as
hold-to-run devices, as described in ISO 12100, automatically self-releasing to the basic position after
actuation; this also applies to the control devices of a transmitter if the machine is operated by means
of radio or similar controls.
If shearer loaders are operated by two people simultaneously, with two radio-transmitters, the
functions ”raise/lower left-hand ranging arm” and if appropriate ”slew left hand cowl” shall only be
initiated from the left-hand control unit, and the corresponding right-hand side functions of the machine
from the right-hand control unit. The same applies for any other functions, with the exception of the
shearer loader haulage drives which can be controlled by both operators. Contradictory simultaneous
commands shall result in the machine stopping.
5.4.2 Safety and reliability of control systems
Control functions of machinery shall be divided into operational functions and safety-related functions.
While operational functions shall comply with good engineering practice, for safety-related functions
increased requirements in respect of reliability shall be met
Safety-related functions may be performed either by separate safety control equipment or by devices
or subsystems of the operational control system. In the latter case, the operational control system (or at
least parts of it) shall meet the requirements of safety-related functions.
All safety-related parts of control systems shall meet as a minimum the Performance Level (PL) “c”
according ISO 13849-1.
5.4.3 Design of control systems
5.4.3.1 General
Electrical control systems shall be designed as per IEC 60204-1.
Hydraulic control systems shall be designed as per ISO 4413.
Ergonomic requirements of ISO 9355-1 shall be addressed.
5.4.3.2 Energizing
The machines shall be fitted with devices to prevent unauthorized energizing, e.g. lockable control
devices or levers attached to immobilization switches that can only be removed in the OFF position.
5.4.3.3 Starting
It shall only be possible to start the machine by intentional actuation of a control device provided for
the purpose. The same requirement applies, when restarting the machine after a stoppage, whatever
the cause is.

ISO 19225:2017(E)
5.4.3.4 Start-up warning devices
Start-up warning devices for shearer loaders shall indicate the starting of the cutting drums by means
of an unmistakable warning signal which is clearly perceptible at the driver’s position, and in an area
extending 10 m in front of and behind the shearer loader.
Start-up warning devices for plough systems shall indicate the starting of movement by means of an
unmistakable audible warning signal which is clearly perceptible along the whole face.
For shearer loaders and plough systems, the drives shall not start up less than 5 s after the beginning of
the warning signal, and only start up while the warning signal is activated.
Audible signals or water sprays shall be used as the start-up warning device on the shearer loader.
Water sprays that may themselves generate a hazard shall not be used as a start-up warning device. A
water jet is regarded as hazardous if the product of its flow rate and pressure exceeds a value of 330
bar l/min at a minimum flow rate of 15 l/min.
Audible start-up warning devices shall meet the requirements of ISO 7731. At a distance of 0,5 m from
the source of sound, the sound pressure level of the warning tone shall be at least 78 dB (A) (see 4.2 in
ISO 7731:2003). The warning tone shall have intermittent characteristic (see 6.3 in ISO 7731:2003).
5.4.3.5 Stopping
5.4.3.5.1 Stopping in normal operation
Each machine mounted control panel, radio-transmitter and remote control console shall be equipped
with a control device for stopping all motors. The stop control command shall override the start-up
command.
The shearer shall be capable of coming to a controlled stop while travelling at maximum speed down
the maximum operating gradient.
5.4.3.5.2 Stopping at the end of the working range
For plough systems, a mechanical stop at the face-ends is required.
Plough systems shall be equipped with overrun monitors based on a detection of the plough position in
the face. The plough drives shall stop automatically if one of the working range end points is reached.
For shearer loaders, a mechanical stop is required to be fitted to the haulage rack at the face-ends. In
addition to this, a position detection system may be installed to control the speed of the shearer when
approaching the face-end positions.
5.4.3.5.3 Stopping in case of an emergency
The machines shall be fitted with emergency stop devices which shall conform to ISO 13850.
They shall stop all relevant movements or functions as quickly as possible to prevent the development
of a dangerous situation without creating an additional hazard.
They shall be designed so that all machine drives are disconnected and locked against start-up by
actuating a switch. The device may also consist of a pullwire acting on a switch and extending over the
whole length of the machine.
Radio-transmitters shall have a pushbutton by means of which all the machine drives are disconnected.
Each remote control console shall be equipped with a device conforming to ISO 13850 capable of stopping
the machine in an emergency. They shall be designed so that all machine drives are disconnected and
locked against start-up by actuating a switch.
ISO 19225:2017(E)
Plough system control devices shall be provided with an interlock device so that all the plough system
and face conveyor drives are stopped immediately if an emergency stop device is actuated.
Remote control consoles shall be provided with a latch-down on/off switch in accordance with
ISO 13850 for stopping the complete system.
5.4.4 Failure of power supply
Re-establishment of the power supply after an interruption or fluctuation shall not lead to a hazardous
situation. See IEC 60204-1:2005, 7.5.
5.4.5 Remote control
If the machine is capable of remote operator control from outside the working area, the control system
shall meet the requirements of the following sub-clauses of IEC 60204-1:2005:
— 9.2.7.2 (control limitation);
— 9.2.7.4 (use of more than one operator control station).
A remotely controlled machine shall be equipped with devices for stopping all operations automatically
and in a safe manner for preventing potentially dangerous operation in the following situations:
— if the data transmission is interrupted;
— if it receives a stop signal;
— if a fault is detected in a safety-related part of the system;
— if no validation signal is detected.
Once stopped, the machine shall not restart except by deliberate actuation of the controls when it has
been determined that it is safe to do so.
The instruction handbook (see Clause 7) shall contain a warning that the operator shall supervise the
machine when operating the machine by remote control.
5.4.6 Radio control
If the machine is capable of radio operator control by wireless means within the working area of the
machine, the control system shall meet the requirements of the following sub-clause of IEC 60204-1:2005:
— 9.2.7.2 (control limitation).
NOTE Radio control does not apply to plough systems.
A radio controlled machine shall be equipped with devices for stopping all operations automatically
and in a safe manner for preventing potentially dangerous operation in the following situations:
— if the transmitter loses the connection to the receiver;
— if it receives a stop signal;
— if a fault is detected in a safety-related part of the system;
— if no validation signal is detected for longer than 1,25 s.
Once stopped, the machine shall not restart except by deliberate actuation of the controls when it has
been determined that it is safe to do so.
The instruction handbook (see Clause 7) shall contain a warning that the operator shall supervise the
machine when operating the machine by radio control.
