Static charge and EX protection – no problem.

When solid and liquid materials are conveyed through chargeable tubes or hoses, electro-static charging (separation of charged particles) occurs due to the friction of the material against the wall and the friction within the medium. The primary hazards are:
  1. The occurrence of discharges that can ignite the explosive mixtures of gas, vapour, mist and dust.
  2. Dangerous or unpredictable behaviour caused by shock when this discharge takes place via the human body.
  3. Process disruptions caused by the medium sticking to the hose wall.
  4. Malfunction of measuring devices and controllers.
The most reliable protective measure is to prevent electro-static charging in the first place by selection of the proper hose. Our products have proven their worth in application in this regard for a number of reasons (see chapt. 14.4).

The evaluation of the particular application and the choice of protective measures to be taken can only be made by the person responsible for design engineering and operation.

Here are the most important domestic and international regulations:
  • German Employers' Liability Insurance Association Guidelines 132 and 104 (BGR 132 and 104, formerly ZH 1/200 and ZH 1/10)
  • German Employers' Liability Insurance Association Guideline ZH 1/730 (fire and explosion protection in systems for the extraction and separation of wood dust and chips)
  • German Employers' Liability Insurance Association Guideline ZH 1/739 (Wood dust – handling and safe work)
  • BIA (BG Institute for Occupational Safety and Health) regulation for industrial vacuum cleaners and dust extractors
  • ATEX Directive 94/9/EC
Information regarding their practical implementation can be found in the technical appendix (see chapt. 14.4) and on the relevant product data sheets. Give us a call; we look forward to providing you with assistance.
