5 Safety requirements andlor measures
5.1 General
Machinery shall comply with the safety requirements and all protective measures of this clause.
In addition, the machine shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant which are not dealt with by this European Standard.
The required performance levels (PLr) of safety related functions of control systems shall be in accordance with EN ISO 13849-1.
For all safety related functions of control systems see Annex F.
NOTE The performance levels quoted in Annex F do not apply to safety devices that do not interact with control systems.
5.2 Means of access
5.2.1 General
Adequate means of access shall be provided to the operators station and areas where routine maintenance, service (e.g. burner adjustment, emission sampling) and material sampling has to be performed as described in the instruction for use.
Means of access shall take into account the erection and dismantling of the plant, including intermediate states of the process (e.g. transportation, part of the machine on jacks, power connections).
Means of access shall comply with EN ISO 14122-1, EN ISO 14122-2, EN ISO 14122-3 and EN ISO 14122-4.
Exceptions and additional requirements are described in 5.2.2, 5.2.3, 5.16.3.4 and 5.17.2.2.
5.2.2 Mobile plants
5.2.1 applies with the following exceptions and additional requirements:
When means of access cannot remain in place for transportation of the plant, due to e.g. applicable road
regulations and dimensions, then they shall meet at least one of the following requirements:
— be completely or partly foldable or retractable;
— be dismountable only by the use of a tool for transportation and be attached to the plant for operation, maintenance, installation and dismantling.
If personal protective equipment (PPE) is needed, anchor points according to EN 795 shall be fitted.
Other provisions (e.g. movable elevating working platforms) shall be described in the instructions for use.
For the access to maintenance points with a frequency less than a month external means of access (e.g. movable elevating working platforms) may be used instead of fixed access.
In this case the plant shall be designed to allow the use of external means (e.g. by providing enough space).
For emission sampling, the fixed means of access may be replaced by other provisions (e.g. movable elevating working platforms). In this case the plant shall be designed to allow the use of external means (e.g. by providing enough space) and shall be described in the instructions for use.
In case of foldable guardrails, they shall be fitted with a mechanical device which stops the guard in the intended position, e.g. limit stop, in order to prevent the guard-rail going beyond this limit.
If it is necessary to remove or to fold guard-rails in accordance with the working process (e.g. pallet handling), a system shall be implemented to protect the operator from falling (e.g. twin-gate lock, rail lock system).
Under exceptional circumstances the width of fixed walkways and working platforms can be reduced to 500 mm, e.g. to allow for a fixed means of access instead of a dismountable or a foldable one. For a distance less than 2 m, the width of walkways can be reduced to not less than 400 mm.
5.2.3 OpenIngs
5.2.3.1 Dimensions for passage openings
a) Opening for horizontal forward movement in upright posture (doors), according to 4.1 of EN 547-1:1996+A1:2008 with x = 150 mm (basic allowance for body movement 50 mm + shoes or heavy footwear 40 mm + PPE which add height to the person, e.g. helmets 60 mm) and y = 70 mm (basic allowance for body movement 50 mm + working clothes 20 mm) taking into account the 95th percentile of the expected user population (P95);
b) for manhole for vertical entry through wtiich rapid active movement needs to be possible, according to 4.4 of EN 547-1:1996+A1:2008 with x = 120mm (basic allowance for body movement 100 mm + working clothes 20 mm) or if PPE needed, x = 220 mm (basic allowance for body movement 100 mm + working clothes 20 mm + PPE 100 mm);
C) For opening for entry in kneeling posture, according to 4.5 of EN 547-1:1996+A1:2008 with x = 120mm (basic allowance for body movement 100 mm + working clothes 20 mm) and y = 120 mm (basic allowance for body movement 100 mm + working clothes 20 mm);
d) for all other passage openings, according to dimensions given in Annex A.BS EN 536 pdf download.
