Safety Data Sheet

According to Federal Register / Vol. 77, No. 58 / Monday, March 26, 2012 / Rules and Regulations

Reactivity: Wet cement kiln dust is alkaline and is incompatible with acids, ammonium salts and aluminum metal. Cement kiln 

dust dissolves in hydrofluoric acid, producing corrosive silicon tetrafluoride gas. Cement kiln dust reacts with water to form 

silicates and calcium hydroxide. Silicates react with powerful oxidizers such as fluorine, boron trifluoride, chlorine trifluoride, 

manganese trifluoride, and oxygen difluoride.

5.3. Advice for Firefighters 

Precautionary Measures Fire: Exercise caution when fighting any chemical fire.

Firefighting Instructions: Do not allow run-off from fire fighting to enter drains or water sources. Do not breathe fumes or 

vapors from fire.

Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory protection.

Other Information: Refer to Section 9 for flammability properties.

SECTION 6: ACCIDENTAL RELEASE MEASURES

6.1. Personal Precautions, Protective Equipment and Emergency Procedures

General Measures: Avoid all contact with skin, eyes, or clothing. Do not breathe dust.

6.1.1. For Non-emergency Personnel 

Protective Equipment: Use appropriate personal protection equipment (PPE).

Emergency Procedures: Evacuate unnecessary personnel.

6.1.2. For Emergency Responders 

Protective Equipment: Equip cleanup crew with proper protection.

Emergency Procedures: Upon arrival at the scene, a first responder is expected to recognize the presence of dangerous goods, 

protect oneself and the public, secure the area, and call for the assistance of trained personnel as soon as conditions permit.

6.2. Environmental Precautions 

Prevent entry to sewers and public waters.

6.3. Methods and Material for Containment and Cleaning Up 

For Containment: Contain and collect as any solid. Avoid creating or spreading dust.

Minimize generation of airborne dust. The product can be slurried by the addition of water but will subsequently set as a hard 

material. Keep children away from the clean-up operation. Transfer spilled material to a suitable container for disposal. Utilize a 

dust suppressant when removing mechanically.
