Following a comprehensive testing and auditing process, the Vertical Fall metal detector from Lock Inspection Systems has just been awarded ATEX approval. Lock is the first UK metal detection manufacturer to comply with the new Directive 94/9/EC on explosion protection. Food and pharmaceutical manufacturers facing mounting pressure to comply with the regulations can now turn to Lock for inspection solutions for incoming bulk raw materials in granular and fine powder form.

The Directive, adopted by the European Union (EU), covers equipment which may be used in potentially explosive atmospheres created by the presence of dust or gases. Risk areas are defined as Zones 22 (minimal risk of explosions) and 21 (occasional risk). Self-certification was awarded for Zone 22 and a notified testing panel reviewed the detector over the course of eight weeks for Zone 21 approval.

Potentially explosive conditions are common in many areas of the food industry, especially bakeries and snack production plants where airborne dust from materials such as flour, cocoa, rice, and grains can create environments which could become explosive. The same can apply in the pharmaceutical industry where powders and granules could develop a similar environment.

Hitesh Hirani, technical director of Lock Inspection Systems comments, "Compliance with international performance and safety standards is a priority for Lock. More and more manufacturers are required to conform to ATEX regulations to demonstrate due diligence and to secure themselves against explosion risks. By investing significant funds and resources into this certification, we can ensure we meet the standards specified by our customers".
