What Velocity can do for you:

A Verrification Dossier must contain:

Velocity Electrical is qualified to install, maintain and verify your hazardous area electrical projects.

The simplest strategy is to minimize the amount of electrical equipment installed in a hazardous area, either by keeping the equipment out of the area altogether or by making the area less hazardous by process improvements or ventilation with clean air.
Many strategies in electrical installations exist for SAFETY.
Intrinsic safety, non-incendive equipment and wiring methods are practices whereby the apparatus is designed with low power levels and low stored energy. In this way, an arc produced during normal
functioning of the equipment or as a result of equipment failure has insufficient energy to initiate ignition of the explosive mixture.
As part of maintaining and ensuring the safety of hazardous areas, personnel in charge are required to keep a Verification Dossier. This is a legal document that not only shows evidence of compliance but also tracks maintenance and modifications. In the unlikely event of an explosion this document will provide the evidence that shows that all steps possible have been taken to prevent an unsafe environment.
It is a requirement of all sites compile and maintains a dossier containing all the information relating to their hazardous areas and equipment stored within them.
It is the responsibility of the person(s) in control of the installation to ensure the dossier is produced.
Failure to produce the document when legally required to do so can result in severe consequences.
In NSW the following is law:
Velocity Electrical provides a professional edge to completing projects and implementing electrical solutions in areas where dangerous concentrations of dusts, vapours and flammable gases can occur.
