and safety checklist analysis, etc.) or demonstration of the plan shall be
conducted;
dangerous, sound, light or a combination of sound and light alarm signal
devices shall be installed. The alarm system shall be able to display the
location and type of fault. The alarm signal shall have sufficient intensity and

higher than the intensity of other sound and light signals in the same area.
5.6.2 Control systems
5.6.2.1 All operations of control and regulating devices shall not create new risks.
5.6.2.2 When an abnormality occurs in the power source, the control device shall ensure
that the production facilities will not cause danger. The control device of production

power source is lost.
5.6.2.3 Artificial intelligence, remote control, automatic or semi-automatic control
systems shall be designed with safety and health guard devices that comply with
intrinsic safety, or other measures shall be taken to prevent danger caused by disordered
control instructions. Production facilities with automatic or semi-automatic control
systems shall be supplemented by manual control devices that can be independently
operated.
5.6.2.4 Highly dangerous production facilities and their safety systems shall be
equipped with monitoring and alarm devices. The early warning and alarm limits of
parameters related to the production process and production safety shall meet the
standards and operating requirements of production facilities.
5.6.2.5 The control device of highly dangerous production facilities shall be installed
in a position where operators can see the movement of the entire equipment. For a
production facility that cannot be seen in full view when the equipment is started, a
start-up early-warning signal device shall be configured. The alarm time of the early-
warning signal device shall meet the requirements.
5.6.2.6 The control system shall ensure that logic errors, electromagnetic interference,
or software and hardware failures in the system will not cause danger. The key
components and control valves in the system shall meet the reliability index
requirements.
5.6.2.7 Control devices AND clutches, braking devices and interlocking devices that
work as safety technical measures shall comply with the reliability index requirements
specified in their product standards.
5.6.2.8 For highly hazardous production facilities, the key regulating devices shall
5.6.4.2 Safety and health guard devices with mandatory functions shall be designed to
prevent accidental start-up of production facilities.
5.6.4.3 A stop control device shall be installed to prevent the power source that is
accidentally cut off from being automatically connected and to avoid dangerous
operation of the production facilities.
5.6.5 Stop
5.6.5.1 Production facilities shall be designed with control devices that can stop it safely.
Stopping devices and starting devices shall be distinguished by color or markings. Stop
control of production facilities shall take precedence over start control.
5.6.5.2 For production facilities controlled by remote control or artificial intelligence,
when the received signal is abnormal or the signal is interrupted, the automatic stop
function or automatic operation function shall be designed without causing other risks.
5.6.6 Emergency stop
5.6.6.1 When the following conditions exist, a production facility shall be equipped
with an emergency stop device:
-- When an accident or production facility failure occurs, the dangerous operation
cannot be terminated quickly through the stopping device;
-- It is not possible to quickly interrupt several units that can cause danger through
a stopping device;
-- The cutting off of a certain unit will lead to other dangers;
-- The whole picture of the control cannot be seen at the console.
5.6.6.2 The emergency stop device shall ensure timely and safe operation at key control
points and shall be effective in all modes without interference from other functions. The
shape of the emergency stop device shall be different from other operating devices and
shall be equipped with a Chinese marking. The color of the emergency stop device shall
be red or have a distinctive red marking. The emergency stop device shall be manually
reset before its control system can be started again.
