Introduction
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is not applicable to continuous casting machines (according to the Scope) manufactured
before the date of its publication.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
Where for clarity an example of a preventative measure is given, this should not be considered as the only
possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent
level of safety is achieved.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
It is assumed that continuous casting machines are operated and maintained by suitably trained
personnel.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine and/or plant manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine and/or plant users/employers (small, medium and large enterprises);
— service providers, e.g. for maintenance (small, medium and large enterprises).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.

control mode
single machines or groups of linked machines of a CCM can function under different control modes
Note 1 to entry: This document distinguishes between control mode(s) and operating mode(s) because there is
neither a common understanding nor a definition in EN ISO 12100 and EN 60204-1. The operating modes (see 3.49)
corresponds to the “control mode” of EN ISO 12100:2010, 6.2.11.9.
3.48.1
manual control mode
3.48.1.1
hold-to-run control
every function is initiated by an operator by means of a button or equivalent device according to
EN ISO 12100:2010, 3.28.3
Note 1 to entry: Release of the button/device stops the function (e.g. movement) immediately.

conditions are met.
3.49
operating mode

3.49.2
safe stop (mode)
movement of the involved equipment is prevented through the control system
Note 1 to entry: The safety level of the safe stop is defined as result of the risk assessment.
Note 2 to entry: Safe stop is not sufficient as a safety measure to perform reconditioning or repair work because
isolation of the equipment from the relevant energy sources is not realized.
Note 3 to entry: Residual risks, e.g. by stored energy must have been secured by other means.
Note 4 to entry: Safe stop mode may also include switching off additional devices, e.g. X-ray.
3.49.3
normal production mode
machine is ready to produce or producing as intended
Note 1 to entry: Production, material handling and activities supporting these processes are covered.
Note 2 to entry: Maintenance according to 3.20 is not covered.
3.50
reduced speed
speed, reduced to minimize the hazardous potential without safety monitoring of speed
Note 1 to entry: In case of failure, an increase in speed may occur.
Note 2 to entry: Applies to linear or rotational speed.
Note 3 to entry: Speed reduced without an enabling device means, that the movement is so slow that the operator
can move away from this dangerous movement in time. Based on a risk assessment, an enabling device may
therefore be required in some cases, even at a reduced speed (e.g. in narrow spaces).
Note 4 to entry: Examples of reduced speeds include speeds of less than 10 mm/s for presses, less than
250 mm/s for robots, less than 250 mm/s for all non-shearing movements and less than 33 mm/s for shearing or
crushing movements.
3.51

Note 1 to entry: Linear or rotational speed.
3.52
unexpected [unintended] start-up
any start-up caused by:
— a start command which is the result of failure in, or an external influence on the control system;
— a start command generated by inopportune action on a start control or other parts of the machine,
as e.g. a sensor or a power control element;
— restoration of the power supply after an interruption;
— external/internal influences (gravity, wind, self-ignition in internal combustion engines, etc.) on
parts of the machine
Note 1 to entry: Automatic machine start-up during operation is not unintended but can be considered to be
unexpected from the point of view of the operator. Prevention of accidents in this case involves the use of
safeguarding.
Note 2 to entry: Definition according to EN ISO 14118:2018, 3.2.

risk assessment
4.1 General
The hazards, hazardous situations and events identified by risk assessment as significant for CCM's and
which require action to eliminate or reduce the risk are listed in Annex F and in Clause 5.
In general, risks and associated hazards are production and plant related. Due to the design variety of
CCM's, an individual risk assessment shall be carried out in any case, considering the special features of
the CCM in question and considering the safety requirements specified in this document. The relevant
required Performance Levels (PL ) or Safety Integrity Levels (SILr) for control devices covering safety
r
functions shall be selected according to this individual risk assessment.
Machinery shall comply with the safety requirements and/or protective/risk reduction measures of
Clause 5. In addition, the machine shall be designed according to the principles of EN ISO 12100:2010 for
relevant but not significant hazards which are not dealt with by this document.
If combinations of machines and/or machine functions described at different parts of the standard are
located in the same danger zone, the different measures shall be considered together.
4.2 Interfaces to the linked/integrated equipment
The individual risk assessment shall include the interfaces to the linked/integrated equipment (see also
5.2.3). For this equipment respective instructions and safety measures including control requirements
for interfaces shall be given in the information for use.
