ELECTROSTATIC PROBLEMS AND HAZARDS
Many industrial processes are hampered by the presence of static electricity. Problems range from poor powder flow, to surface contamination of newly finished and stored items, and shocks to personnel.
Electrostatic discharges (sparks) can also trigger fires and explosions in industry endangering life and causing thousands of pounds worth of damage.
Some companies are not even aware that these problems are due to static. However, once the cause is identified, a workable solution can be provided.

JCI ELECTROSTATIC INTRUMENTS
**NEWS**
Chilworth Global Ltd Acquires John Chubb instrumentation (JCI)
 Chilworth Technology Ltd (CTL) is pleased to announce the acquisition of JCI - a manufacturer of specialist instrumentation in the field of electrostatics. JCI have an enviable reputation around the world for the quality and specification of their electrostatic measurement equipment. The JCI business fits alongside CTL’s existing range of specialist process safety test instrumentation and its range of consultancy and testing services. It is expected that Chilworth’s direct presence, and experience in marketing, around the world will lead to rapid growth as a result of this exciting new acquisition. For the full press release see click here. For information on the full range of JCI products visit our website at www.jci.co.uk.
JCI is the brand name for a range of specialist instrumentation in the field of electrostatics, and has been part of Chilworth Global since February 2009 (see here for the original press release). Three instruments are particularly important within the JCI product range: - JCI 140 Hand-Held Static Monitor… is a handheld detection and measurement instrument used widely in many industries and by electrostatic professionals.
- JCI 131 Adverse Conditions Field Meter… is even suitable for long term monitoring of electric field outdoors.
- JCI 155 Charge Decay and Capacitance Loading Measurement System… assesses the electrostatic properties of materials for safety and QA purposes.
All have a range of optional accessories enhancing and extending functionality, making for one of the most comprehensive range of exceptional quality instruments of their type in the world.
Further information about the range of JCI instruments can be found on the dedicated web site: www.jci.co.uk.
For specialist process safety instrumentation and test equipment, also manufactured by Chilworth, see [link to Instrumentation page].
Ian Pavey is head of electrostatics at Chilworth Global. He was the leader of a multinational research programme with significant investment, investigating powder handling and processing problems caused by static electricity in industrial processes. Ian is also a former committee member of the Static Electrification Group of the Institute of Physics.
His expertise is supported by a team of specialists and state-of-the-art laboratory facilities.

 | A Brief Guide to Static Solutions
Companies involved in the manufacture and distribution of chemicals, household products, pharmaceuticals, agrochemicals, plastics and plant protection products need to establish whether their processes are directly impacted, or personnel endangered, by the effects of static electricity.
This compact guide explains the processes at work with static and how to identify, minimise or even totally eliminate the resulting problems and hazards. (Also available in print)

|  | STATIC ELECTRICITY & RELATIVE HUMIDITY DATASHEET
If static is believed or suspected to be a hazard it is crucial to understand the effect of Relative Humidity on the electrostatic properties of the material involved. Only then will it be possible to propose effective measures for the avoidance of static hazards and solving electrostatic problems.

|  | STATIC ELECTRICITY AND ATEX / DSEAR DATASHEET
In June 2003, it became a legal requirement throughout Europe that new and modified plant must comply with the requirements of the European Directive ATEX 137, which in the U.K. is implemented as part of the DSEAR 2002 regulations. Of all sources of ignition that must be considered under this legislation, the ATEX Directive draws explicit attention to only one – STATIC ELECTRICITY

|  | STATIC ELECTRICITY AND FIBCs DATASHEET
Flexible Intermediate Bulk Containers (FIBCs) are used for the storage, packaging and transportation of powders and granules in many industries. What is not always appreciated is that basic FIBCs can produce electrostatic discharges capable of igniting flammable gases, vapours and dust clouds.
