Grounding
Why is grounding necessary?
Special care is required when collecting flammable liquids. Static charging may occur during drainage which is the cause of static sparking and increased fire risk. SymLine built-in solutions made of electrostatic conductive plastics prevent static charging and can be secured by means of additional grounding connections.
There are a number of directives and regulations that define how to assess and avoid risks of ignition and which proactive measures to take. Of special importance are the German Trade Association Rules for Safety and Health at Work (BGR) issued by the German Federation of Institutions for Statutory Accident Insurance and Prevention, HVBG): BGR 132 - Directive ‘Static Electricity’. In terms of contents this corresponds mainly to the international norm CENELEC 50404 and the latest Technical Regulations for Hazardous Substances (TRGS) TRGS 727 (formerly TRBS 2153) - Avoiding ignition risks caused by electrostatic charging. Electrostatic conductive synthetic materials which have a volume resistance > 104 Ω & < 109 Ω can be used in protective systems which are subject to the ATEX directive provided they are sufficiently grounded.
ATEX compliant!
SymLine uses high-performance synthetic materials, provides an ideal link to safety cabinets and observes the ATEX directives.
