Coverage assessment, the Crowcon way

Traditionally, fire and gas mapping was conducted manually by experienced engineers. However, by using sophisticated computer aided design (CAD), Crowcon can provide a detailed report based on 3D site images which identifies gas and flame hazards. From this, we can recommend precise detector quantities and locations, so you can be 100% confident your site is covered.

What to expect
from us

Whether it’s for new sites/installations, or for established detection systems – you can expect careful consideration of alarm set-points, performance requirements, and the environmental conditions to provide optimal workplace safety.

Each area of the site is analysed to calculate coverage and ensure performance requirements are correct.

The Consultant will complete the performance target review and present the findings in a simple, concise report.

System design is optimised to achieve the best possible balance between safety and economy, reducing operating costs by ensuring that the number of devices used is minimised while the required level of safety is maintained.

All in-line with relevant, country specific certifications and standards.

Coverage assessments

Valutazione della copertura dei rivelatori di gas

A number of simplifying assumptions are used in order to make it possible to assess sites. It is assumed that all gas detectors are either ‘point’ or ‘open path’ gas detectors, and that gas is detected if the accumulation envelopes a detector or intersects the track of an open path detector.

Each area assessed is represented as a volume specified in terms of its length, width and height.  The assessment results are summarised diagrammatically clearly depicting the areas of the site that are covered, and not covered by the existing or  detectors. A typical gas detection coverage assessment diagram is shown to the left.

Safety Assurance

Health and Safety Managers are increasingly required to demonstrate the rationale behind the selection of the safety systems deployed on their sites. Greater assurance is needed to confirm that the installed detectors and systems provide the intended levels of area coverage and protection.

Guidance documents are published by national authorities, but they only detail general recommendations for gas detector selection and placement. They do not provide the definitive guidance that enable systems to be installed without the assessment by specialists in the discipline.

Better safe than sorry…

Our fire and gas mapping ensures you have the most comprehensive possible cover against gas hazards. When all it takes is one blind spot to cause untold damage and harm to your people and property- can you really afford not to?
