DSEAR for spray booths
Spraying can create a flammable mist or vapour, while mixing, cleaning and waste handling can introduce separate release sources.
Check my situationThe booth boundary is not the assessment boundary
A compliant-looking booth does not answer how products are stored and mixed, how guns are cleaned, where contaminated waste goes or what happens when ventilation is unavailable.
- What do the product safety data say about flashpoint and physical hazards?
- How are mixing, spraying, flash-off, drying, gun cleaning and waste handled?
- What interlocks, airflow checks and rules prevent spraying when extraction is ineffective?
What to do next: Include the booth, adjacent process steps and foreseeable ventilation failure in the same project brief. Ask whether zoning and equipment-suitability outputs are included.
Map every release point
Consider the paint or coating store, mixing point, application, flash-off or drying, gun cleaning, contaminated waste and maintenance. Each can create a different release duration and extent.
The assessment should use the actual products and operating conditions. Water-based branding alone is not a complete answer if flammable cleaners, additives or other coatings remain in use.
Ventilation and ignition controls must connect
Ventilation may prevent or limit a flammable atmosphere, while suitable equipment and static control address ignition. The assessment should explain the assumptions that make each control effective.
Maintenance, filter condition, airflow indication and interlocks matter because the risk can change when the booth is degraded or used outside its design conditions.
