determining the concentration of combustible powder coating with regard to the lower explosion limit is described in the European standard DIN EN 16985. Appendix 1 describes how the concentration of the powder coating, which may be present in the spray booth, can be calculated.
This Code of Safe Practice contains recommendations and guidance for the safe application of coating powders by electrostatic spraying. It covers both thermosetting and thermoplastic powders. This guidance does not cover the application of coating powders containing lead chromate pigments or TGIC1 .
CEPE - Safe Powder Coating Guideline Page 3 2. Dust explosion and fire hazards 2.1 Causes 2.1.1 Powder coatings, being fine organic materials, can give rise to dust explosions. A dust explosion may occur when both: 3 (i) the concentration of dust in the air is between the Lower Explosive Limit (LEL) and Upper Explosion Limit (UEL). and
7 Οκτ 2019 · This article will discuss the requirements of the 2019 edition of NFPA 652 and provides some practical measures for controlling dust flash fire and explosion hazards associated with the handling, processing and storing of combustible powders.
suitable for explosive, corrosive and flammable substances. 3 Consider the need for explosion relief for combustible solids, and ensure equipment is appropriately earthed.
23 Μαΐ 2017 · Explosion protection requirements in a new coating. As a rule, manufacturers of solvent-containing paints and varnishes have to prevent explosion hazards and define hazardous areas (zones). Explosive atmospheres may also occur when water-based varnish or powder coatings are used.
Dust explosion occurrences are extremely rare in powder coating operations because the conditions which cause them normally do not occur when a properly designed and maintained system is used.
