relining machinery/device
machine for manual or automatic installation of refractory lining inside the converter
Note 1 to entry: Associated lifting, lowering and travelling devices for material transport and access to the workplace are induded.
Note 2 to entry: For the associated lifting devices of relining machinery the Directive 95/16/EC on lifts is not applicable (see also ArtIcle 24. PoInt 3, 9th indent of Machinery Directive 2006/42/EC).
4 List of significant hazards
All the significant hazards, hazardous situations and events, as far as they are dealt with in this standard, identified by risk assessment as significant for this type of machinery and which require action to eliminate or reduce the risk are listed in columns I and 2 of 5.2, Table 1.
In addition, the manufacturer shall carry out a plant-related risk assessment. Including Interfaces to auxiliary equipment, according to EN ISO 12100:2010, Clause 4 to identif’ any other significant hazard of the machine/equipment. Significant hazards identified in this plant-related risk assessment but not dealt with in this standard shall be reduced by applying the principles of EN ISO 12100.
5 Safety requirements and/or measures
5.1 General
5.1.1 Introduction
Converter plants conforming to this European Standard shall comply with the safety requirements and/or measures set out in Clause 5 together with those set out in Annexes A, B and C and the information for use as defined in Clause 7.
Special consideration shall be given to CO emission due to process transients and/or equipment failure. In general, risks and associated hazards are production and plant-related. The variety of different plants
(i.e. different combinations of machines, different boundary conditions) could not be covered In all details in a European Standard. To deal with this fact, an individual risk assessment of the equipment in question shall be carried out (see Clause 4) considering the safety requirements of this European Standard.
The manufacturer shall include in the information for use all details required for a safe operating process under normal operating conditions. He shall also describe the specific safety measures in case of special conditions, e.g. maintenance and adjustment work.
If in addition to the technical measures further measures for risk reduction by organizational precautions according to EN ISO 12100:2010. Clause S are necessary, the manufacturer shall include in the Information for use details of this measures and the necessary information considering the residual risks.
5.1.2 Planning phase
The manufacturer shall undertake during planning phase together with the user a layout-check to ensure good placement and safe operation of the converter plant, in particular with regard to:
— position of physical emergency systems;
— accessibility;
— maintenance and cleaning
— movement of parts of the equipment and material;
— prevention of emissions hazardous to health at the work stations (e.g. avoiding harmful emissions);
— considering ergonomic requirements;
— escape routes.
5.1.3 Safety layout
A safety layout shall be prepared. 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 at the converter plant.
It is recommended to involve the user of the equipment. e.g. regarding escape routes, fire extinguishing systems, etc.
If applicable, the following shall at least be illustrated:
— areas where the risk of injury due to contact with liquid metal or slag including spraying is given;
— emergency stop buttons;
— escape and access routes (if necessary. e.g. for large plants);
— areas influenced by low oxygen and/or harmful gases (e.g. CO or asphyxiating gases);
— visible/audible warning devices;
— safety related marking;
— safety signs;
— fixed guards (e.g. fences);
— moveable guards (e.g. safety doors);
— light barriers or safety scanners.
The safety layout shall be part of the Instruction for use.
5.1.4 Safety devices and protective measures
5.1.4.1 Safety devices
Safety devices and devices with safety function (e.g. limit switches, locking devices) shall be accessible for maintenance. These devices shall be protected against damage and the possibility of defeating or circumventing in a foreseeable manner (for further details, see EN ISO 14119 and EN ISO 13849-2:2012, Annex Lii and D.2).
All relevant energy isolating devices, either main or local, shall include facilities to apply one or more padlocks (see EN 1037).
5.1.4.2 Guards
Guards used to prevent access to danger zones shall be selected as appropriate for the degree and frequency of access to be permitted. e.g. an enclosing guard or distance guard, fixed or movable with interlock. This selection shall be made according to EN ISO 14120.BS/EN 16774-2016 pdf download.
