Is This How You Want Your Workers to Behave? What’s wrong with this scene? 
Answer This scenario lends itself to the following safety hazards: √ Safety Hazard 1: somebody might slip on the concrete dust √ Safety Hazard 2: somebody might breathe in the dust and suffer respiratory damage √ Safety Hazard 3: the airborne concrete dust is combustible and could result in an explosion The Moral: Workplace negligence can do serious damage. Let’s focus on the hazard of airborne combustible dusts. WHAT’S AT STAKE Dust Explosions—The Body Count Major U.S. Dust Explosions
HOW DUST EXPLOSIONS OCCUR The 2 Things that Have to Happen 1. THE AIR CONTAINS A DANGEROUS CONCENTRATION OF DUSTS Certain dusts mix with air to form a mixture that can explode. But there must be enough of the dust in the air for explosion hazards to exist. The minimum amount/percentage of a dust capable of exploding, i.e., “combustible dust,” is called its Lower Explosive Limit (LEL). Each combustible dust has a different LEL, as depicted in the following table:
2. SOMETHING HAS TO IGNITE THE DUST An explosive mixture of combustible dust will only explode if something ignites it, i.e., sets it off. Sources of ignition typically include heat and electric sparks. How much heat does it take to ignite a combustible dust? Answer: It depends on the particular dust. 
8 WAYS TO PREVENT DUST EXPLOSIONS The key to preventing dust explosions is making sure these 2 things don’t happen. The following are 8 other things you can do to prevent dust explosions at your workplace: 1. Take cleaning and housekeeping measures to keep dusts off surfaces and prevent them from accumulating in the air. 2. Use dust collection systems and filters to keep dusts out of the air. 3. Inspect the workplace for dust accumulations and residues. 4. Be aware of the combustible dusts that may be present in your workplace. 5. Be aware of the LEL and potential ignition sources of each of these dusts. 6. Don’t use ignition sources like welding torches, electrical equipment, and even matches in areas that contain these combustible dusts. 7. Be aware that heat and electricity from forklifts and other powered mobile equipment can be a source of igniting dust explosions. 8. Know your emergency response and evacuation plan so you’re ready in case a dust explosion or fire does occur.
