3 Modification to "5.1.4 Safety layout"
Replace 5.1.4 with
"The manufacturer shall prepare a safety layout document of the hydraulically powered open die hot
forging press. The aim of the safety layout is to give information (normally by means of one or more
drawings) about the physical position of safety related elements like, e.g.:
a) isolators according to EN 60204-1;
b) emergency stop buttons, according to the requirements of EN ISO 13850;
c) escape routes (if necessary, e.g. for large plants);
d) other safety-related safety marking, according to the requirements of EN ISO 7731 and EN 842;
e) segregating devices (guards, fences, trip devices etc.) intended to prevent access to danger areas of
the plant according to the requirements of EN ISO 13857, EN 953 and EN ISO 14122-2;
f) doors and other points of access to the plant (where required with related locking and/or interlocking
devices);
g) warning devices and safety signs (warning signs for, e.g. forbidden access, X-rays);
h) fire precautions.
The safety layout shall be included into the manufacturer's instructions for use.".
4 Modification to "5.1.6 Railings"
Replace the text of the headline of 5.1.6 with:
"Guard-rails".
Replace the text of 5.1.6 with:
"Guard-rails shall conform to EN ISO 14122-3.
Guard-rails are to be considered as means to deter or impede access to hazardous areas, i.e. a physical
obstacle which only reduces the probability of access (but not totally prevents it), offering an obstruction
to free access (see 3.27 of EN ISO 12100-1:2003). Guard-rails can be used as a measure to prevent
unintentional access of unauthorised persons to zones where residual risks exist.
Therefore, guard-rails are not permitted as the sole measure of safeguarding hazardous areas in case of
significant risks (e.g. from moving machinery or processed material). Guard-rails shall be used for cases
where the hazards of slips, trips and falls are involved.
The evaluation of the degree of risk associated to a specific hazardous situation shall be performed
during individual risk assessment by the manufacturer in compliance with Clause 8 of
EN ISO 14121-1:2007. However, guard-rails, are not to be considered as sufficient measures of
safeguarding to address hazardous situations included in Table 1, where only significant hazards are
dealt with.
In addition, the manufacturer shall give information in the instructions for use (see Clause 7) about the
foreseen restrictions for access to the areas surrounded by the guard-rails and about the nature of the
existing residual risks.".
5 Modification to "5.1.9 Warning devices and safety signs"
th
Add after the 5 paragraph the following new one:
"Warning signs about non-ionising radiation for persons with implanted medical devices shall be fixed
where applicable.".
6 Modification to "5.1.11 Electrical equipment"
Replace the existing paragraph with:
"Electrical equipment shall conform to EN 60204-1 and withstand the hazards identified in the risk
assessment required at the design stage and taking into account the requirement set out in Annex B.
Safety devices shall be protected against damages. In particular they shall be robust to withstand
damages whiles continuous operation in the respective area.".
7 Modification to "5.1.13 Guards"
Replace the text of the sub-clause with:
"Guards shall be provided to prevent access to a danger zone. They shall be selected as
