If there is a flammable atmosphere present, such as a solvent vapour or dust cloud, then the risk of explosion hazard may cause concern. Less dramatic, but also very important, is the possibility of ESD damage in electronic manufacture . Here, even a small amount of static can destroy a sensitive electronic component, resulting in component losses reduced reliability and increased rework costs. Where static electricity is controlled to reduce these effects, it is usually by choice of materials specified as having certain electrical properties. In many cases, these will be specified to particular national and international test standards .
Static electricity can also be useful in new technology .
An example is in the application of electrostatic separation in recycling of materials. Electrostatics also forms the basis of some sensor solutions , for example where the level of a liquid or size or proximity of an object may be detected.

ESD damage can cause failed components leading to equipment test failures and rework costs, or latent component failures which could cause failures in equipment in the field. In Europe, guidance is given in the EN100015 series of standards, and many manufacturers adhere to this as part of their Quality Assurance procedures.
