EHS / Management systems

Environmental Protection as well as Occupational Health and Safety are integral components of our corporate culture. As such, we expect our suppliers to make every effort to protect the environment as well as taking responsibility for the health and wellbeing of their employees. Within a company, these principles should be implemented within the framework of a strategic approach. Such approaches can vary among size and significance of a company. Accordingly, we have categorized these requirements.

Product-related environmental protection

European legislation like REACH and RoHS require manufacturers and suppliers to provide information about restricted substances that needs to be passed on through the supply chain. As such, Siemens Energy and its affiliated companies requires suppliers to declare whether products delivered to Siemens Energy contain any substances that are restricted by such legislation. For doing so, suppliers need to complete the Siemens Energy Substance Declaration to begin with, which is based on the List of Declarable Substances. In cases where suppliers have products that contain restricted substances as specified through the Siemens Energy Substance Declaration, suppliers must declare such content to Siemens Energy. To provide the opportunity for our suppliers to increase their efficiency concerning substance declaration, Siemens Energy prefers the centralized database, called BOMcheck, where suppliers can insert their substance declaration.

Technical Safety – Dangerous Goods

The aim of the dangerous goods regulations is also our goal: To prevent – as far as possible – risks to persons or property and damage to the environment, the means of transport used or to other goods as far as possible. Compliance with the dangerous goods regulations assures that risks will be eliminated or reduced to a minimum.

Compliance with dangerous goods regulations is guaranteed by a worldwide network of properly trained employees throughout the complete transport chain - classification of our products, selection of transport mode, packing, shipping, use of service providers, etc. Our procurement and development departments are already focusing their attention on these regulations to assure our products can be transported worldwide in full compliance with the applicable legal requirements. As a global player, we also strive to serve our customers in this area in a safe manner without delay or objection.

Our suppliers are required to ship dangerous goods in compliance with the dangerous goods regulations applicable for the goods and the transport mode ordered, with simultaneous consideration of relevant national or operator variations. This may also include additional requirements for permitted inner packaging for planned successional transports as given in an order which also have to be taken into account.

During the initial process of quotation, suppliers are required to provide data on the dangerous goods to ensure that:

  • dangerous goods will be identified even when contained in equipment
  • especially for components and assemblies which will be integrated into a product, the possibility of transporting the planned product can be checked by us at the earliest stage of development. 

When making a contract with service providers (freight forwarders, packers etc.), the necessary dangerous goods information will be provided by the contracting entity at Siemens Energy (also including affiliates) as required in the dangerous goods regulations. 

The list of the dangerous goods data on which we need information is available in the Downloads. They may alternatively be given as part of a Material Safety Data Sheet containing all the necessary data if dangerous materials are concerned. For lithium cells or batteries - also packed with or contained in equipment – and for non-spillable, wet batteries – also contained for example in an uninterruptible power supply - the given forms (see Downloads) have to be used if the certification (specific for battery type and manufacturer) is not already available at Siemens Energy.

According to our experience, the following points have to be kept in mind:

  • Some goods classified as dangerous goods may be transported as a complete or partial exception to the dangerous goods regulations of a specific carrier. This must not result in the classification "no dangerous goods" being given! The correct classification according to the dangerous goods regulations has to be given to ensure that goods can be properly classified for all transport modes used.
  • Lithium batteries may only be assembled from tested lithium cells and have to be tested according to the applicable battery tests (38.3 UN Manual of Tests and Criteria).

If you have any questions regarding this subject, contact your Siemens Energy partners. They will involve their competent safety adviser for the transport of dangerous goods, the competent division officer or the Corporate Office of Radiation Safety and Dangerous Goods as and when required.
