How to avoid spontaneous combustion of shot blasting dust

Safety Alert: Spontaneous combustion of shot blasting dust is a critical hazard that can lead to devastating fires. Prevention is not just a recommendation—it is a necessity.

🛡️ 4 Essential Safety Measures

1. Strict Ignition Control

   • Always control ignition sources during inspections.
   • Avoid sparking in circuits.
   • Electric Welding Safety: Thoroughly clean surrounding dust before welding.
   • Trial Run: Wait at least 10 minutes after repairs before restarting.
   • Strict Prohibition: No smoking or open flames near the shot blasting area.

2. Static Electricity Prevention

   • Use conductors or conductive materials instead of high-insulation materials.
   • Ensure good grounding for all related equipment and structures.
   • Cloth bags must maintain high electrical resistance standards.

3. Dust Management & Heat Dissipation

   • Prevent the accumulation of rust and dust to avoid heat energy buildup.
   • Timely Cleaning: Remove dust from the collector promptly.
   • Regular Maintenance: Carry out back blowing and dust discharge during every shift.

4. Personnel Training & Awareness

   • Conduct theoretical and practical training for all operators.
   • Ensure employees understand that rust dust is flammable.
   • Maintain constant vigilance over the working condition of dust collectors during production.

It is very important to complete the above four tasks well to prevent the spontaneous combustion of shot blasting dust .
