Foreword
This document (EN 13042-2:2004) has been prepared by Technical Committee CEN/TC 151 “Construction
equipment and building material machines — Safety”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by March 2005, and conflicting national standards shall be withdrawn at the latest by
March 2005.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association and supports essential requirements of EC Directive(s).
It is one of a series concerning machinery for the treatment and processing of hollow glass.
For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

0 Introduction
This document is a type C document as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this type C document are different from those which are stated in type A or B documents, the
provisions of this type C document take precedence over the provisions of the other documents for machines that
have been designed and built according to the provisions of this type C document.
Handling machines for the feeding of melted glass are independent mechanical devices working in one or more
axes to pick up melted glass from the (working) bowl of (melting) furnaces, e. g. by winding up the high-viscous
melt on ball-shaped receivers (ball-feeders) or by sucking up into gathering containers (suction feeders). The
handling machines transport the gathered post off melted glass to the forming machine or to the glass blower's
place and deposit it there.
Noise is not a significant hazard. Noise emitted by air-cooling devices of machinery linked to the handling machine
for feeding may be so high that there is a need for the operator of the handling machine to wear ear protection.
When compiling this document, it was assumed that:
 state of the art requires an interference in the motion path of the handling machine by the operator especially
during the first cycles of the forming machine to be supplied;
 adequate lighting is provided.

1 Scope
1.1 This document contains the requirements for safety for the design and installation of stationary handling
machines for feeding from the taking up of a post of melted glass out of the working bowl of a glass melting furnace
through transport to delivery to a glass blower or to a forming machine for hollow glass.
1.2 This document deals with all significant hazards, hazardous situations and events relevant to machines for
feeding, when they are used as intended and under the conditions foreseeable by the manufacturer (see Clause 4).
This document specifies the appropriate technical measures to eliminate or reduce risks which can arise from these
significant hazards.
1.3 This does not deal with the exclusive feeding with shearers (shears) alone with the transport of the melted
glass post by its own weight in free fall or by trueing (gob feeder, see prEN 13042-1).
1.4 This document is not applicable to handling machines for feeding which are manufactured before the date of
publication of this document by CEN.
