European Machine Directive 2006/42/CE

 

European Machine Directive 2006/42/CE requires the installation of appropriate audible and visual warning devices as an essential safety requirement for the operator in industrial environments. The majority of the issues examined in the directive relate to design characteristics that assure complete safety of the whole “machinery system”.
Point 2 of the introduction highlights the ever increasing importance of a signalling device onboard a machine, i.e.: “The machinery sector is an important part of the engineering industry and is one of the industrial mainstays of the Community economy.
The social cost of the large number of accidents caused directly by the use of machinery can be reduced by inherently safe design and construction of machinery and by proper installation and maintenance.”

By developing signalling equipment suitable for all the safety conditions that the system provides for and, not forgetting our philosophy that has always accompanied our “modus operandi” that is…“AN ALARM SIGNAL MUST ALWAYS BE ABLE TO REVEAL AN IMMINENT DANGER AND A DANGEROUS SITUATION”…SIRENA has concentrated on the following important chapters of the Directive:• Par. 1.7 – INFORMATION

1.7.1.2 – Warning Devices

• Par. 3.6 – INFORMATION AND INDICATIONS

3.6.1. – Signs, signals and warnings

Taking into consideration the contents of the above mentioned points SIRENA is in a position to present to the customer products for installation onboard machinery that fully comply with the safety requirements demanded.

If we look further into the details relating to signalling applications, the Directive reverts to specific European norms regarding machinery safety issues that specify the constructive and functional technical requirements audible and visual warning device must have to be effective and distinguishable.

We detail below a list of the norms and the most important paragraphs with which SIRENA makes reference to in order to produce the INDUSTRIAL range of products (acoustic and visual) in full conformity to the fundamental technical and functional requirements:
