What needs to be assessed?

DSEAR risk assessment is needed for any process, area or equipment that involves substances, and if enough quantity is suspended in air, will ignite if an ignition source is introduced. Typical examples include:

✅ Spray Paint Booths

✅ Spray Dryers

✅ Blenders

✅  Grinders

✅ Ink Press

✅ Coal, wood, and paper activities that generate dust.

✅ Flammable Paint Stores

✅  LEV Extraction system removing extremely volatile substances.

The Dangerous Substances Explosive Atmosphere Regulations 2002 sets out that companies with potentially explosive atmospheres must complete an assessment to determine the level of risk and ensure adequate controls are in place. Hence the assessments should really go beyond what the ATEX Directives originally intended.

Your Questions Answered

A DSEAR Assessment is a systematic review of a process, area or activity against strict criteria to determine, first of all if it is explosive, then how much of an impact such an explosion would have.

Furthermore, it identifies the zones which are explosive and defines them into a classification based on likelihood and composition if it is a Powder / Dust or if it is a Gas / Vapor.

The next bit is the most important. What to do with the information from the assessment. We pride our service on a very thorough assessment followed through with all practical recommendations, Staff training, Signage installation and where needed, working with other businesses to safeguard yours (Such as Explosion Panel installation). Because we are in the industry of knowing what’s needed, we know many suppliers that would be best for your needs.

To be able to complete a DSEAR Assessment, the HSE have stated within their DSEAR ACOP that someone “Competent” must complete the assessment.

With DSEAR assessor trained staff and over 10 years working in industries with explosive atmospheres, we have time and time again satisfied the HSE of our competence to complete DSEAR Assessments for our clients, so not only will you get a great service and a service that flows through with all identified actions, you will also be in very confident and competent safe hands.

In fact, depending on the risk levels of the operations, the HSE generally recommends that DSEAR be updated every 3-5 years. Normally a DSEAR Assessment should be completed as soon as any potential explosive atmospheres are identified. Ideally in a design sage but more often than not, it’s after things are already in place. If you do have a facility that has a high risk or large volumes of substances, 6-monthly is normal and the original assessor may be the best person to do this.
