The first step in keeping your facility safe is to be aware of the categorised hazardous area zones present. With so many factors to consider it can be a daunting task, but this is where our hazardous area classification drawings come in.

Hazardous Area Classification drawings give you an overview of the presence of ignition sources and potential risks to allow you to select and install equipment without the worry of fire or explosion. They are also vital for the safety of workers to inform them of safe working areas.

Each detailed diagram includes:

Zoning - Clear indication of hazardous zones such as gas or dust environments. 
Location - Identification of where the hazards are present and any ignition sources.
Type - The particular substances present whether they are gas, dust or vapour.
Ventilation - The identification of ventilation or openings such as windows, doors, ducts and fans.

We have in-house experts who use sophisticated software and work with you to develop personalised drawings that will become an essential asset in safeguarding your staff, equipment and property. 

Simply contact us and we can get started in providing you with your hazardous area classification drawings.
