1. Explosion prevention
void the occurrence of an explosion
• Replace combustible materials by non-combustible materials
• void materials with a fine particle size. Note: fines are often
produced e. g. by handling a coarse product
• Limit concentration of combustible material used
• Use sealed plants to prevent dust releases and deposits
inside buildings or outside
• Use dust extraction systems to control the extent of a dust cloud
• Implement good Housekeeping (regular cleaning plan) –> see also point 3
• Minimize flat surfaces, ledges to prevent dust deposits
• Use an inert gas blanketing where useful and economic
void effective ignition sources
• Limit surface temperatures below 2/3 of minimum ignition temperature
or approx. 200° C (75 K) below auto ignition temperature (e.g. broken bearings, friction, etc.)
• void rubbing, contact of rotating parts (limit rotational speed, choice
of materials, separation distance, avoid tramp metal)
• Use a permit-to-work system to control hot-work (welding, cutting, etc.)
Prohibit smoking and open fire in general
• Install appropriate electrical and non-electrical equipment
• void electrostatic charge generation
(choice of materials - earthing measures – effective bonding)
• Spark detection and extinguishing
• Consider all other ignition sources (e. g. self-heating, lightning)
2. Constructional explosion protection
Limit the dangerous consequences of an explosion:
• Explosion-resistant design (explosion-pressure-resistant or explosion-pressureshock resistant)
• Explosion venting
• Explosion suppression
• Explosion isolation, decoupling (prevention of explosion propagation)
3. Organizational measures
• Comprehensive operator education and training
• Operator instructions, cleaning plans, good housekeeping
• dequate maintenance
• Permit-to-work system for welding, hot-work and electrical operations
(authorized persons only)
4. Building precautions
• Isolation of buildings and equipment to prevent transmission of fires and explosion
• Fire zones, clearly marked Hazardous Zones (Ex) / Explosion protection document
• Sealed and tight piping and conveying systems
• Smooth surfaces and easy-to-clean floors, easy access to elevated plant areas
