Occupational Safety and Health is a major concern throughout the world. Problems such as a broken limb, the loss of an eye or persistent backache have to be dealt with and measures taken to minimise the risk of these things happening at the workplace.

Tracking the tiniest cracks – with H2O wastewater treatment. Heavy use, material fatigue and material faults can cause tiny cracks in plastic and metal parts. These are so small that they are invisible to the naked eye. But they can still be relevant to safety, e.g. on the wings of passenger jets. That’s why these parts are regularly checked for micro cracks. One way of doing this is the dye penetration process, where the part to be checked is first thoroughly cleaned. Applying a special dye and using a suitable developer, the tiniest cracks become visible on the surface, enabling defective parts to be easily identified and replaced. If the crack check reveals no problems, the transfer agents are washed and approved for further operations.
