Administrative data
First-aid measures
- General advice:
Standard first aid measures should be employed if an adverse reaction to
CMS exposure occurs. Supportive medical treatment, as indicated by the subject’s condition, is recommended.
- Following inhalation:
At machinery and places where CMS dust can be generated. If coughing, shortness of breath or
other breathing problems occur, move the subject to fresh air. Seek medical attention if symptoms persist. If necessary, restore normal breathing
through standard first aid measures.
- Following skin contact:
Repeated exposure to CMS may cause skin dryness or cracking. Application of a skin barrier cream may help to avoid contact of the skin with CMS. Clothing contaminated with CMS should be removed, and contaminated skin washed with plenty of water and soap. Seek medical attention if redness, swelling, itching or burning occurs.
- Following eye contact:
Flush contaminated eyes immediately with a steady flow of water. Seek medical attention if redness, swelling, itching, burning or visual disturbances occur.
- Following ingestion:
known or expected. If ingestion of CMS occurs, do not induce vomiting. If the victim is conscious,
give several glasses of water to drink. Obtain medical advice if symptoms develop.
- Most important symptoms and effects: Exposure of the product to skin and eye as well as inhalation is typically just causing acute irritation as long as the exposure is in progress. Ingestion does not normally cause any acute symptoms.
Fire-fighting measures
- Suitable extinguishing media:
All standard firefighting techniques and substances are suitable.
- Unsuitable extinguishing media:
None known.
- Special hazards arising from the substance or mixture:
Not applicable. CMS does not pose an unusual hazard in the case of the substance or mixture a fire. CMS will not burn. Hydrophobic CMS with a carbon content of more than 5% may lead to development of CO and CO2, and form slightly explosive mixtures with air.
- Advice for fire fighter: None
Accidental release measures
- Personal precautions:
Wear suitable protective clothing. Wear eye/face protection.
- Protective equipment and emergency procedures:
An approved protective equipment and dust mask should be worn if dust is generated during handling.
- Environmental precautions:
Synthetic calcium magnesium silicate is virtually inert and has no known adverse effect on the environment.
- Methods and material for containment and cleaning up: Dampening with water can reduce dust. Sweep or preferably vacuum up and collect in suitable
containers for recovery or disposal in accordance with local authority requirements.
Handling and storage
- Precautions for safe handling:
CMS should be handled in well-ventilated areas. Avoid raising dust. Take precautionary measures against possible build-up of
electrostatic charge in presence of flammable or combustible gases, vapours, or liquids. When handling CMS, use suitable gloves. Application
of a lotion or barrier cream is also recommended to prevent drying of the skin. If repeated or prolonged skin contact is likely, protective
clothing should be worn. Eye protection is also recommended. General and/or local exhaust ventilation should be provided to maintain airborne CMS levels below the occupational exposure limit. If this is not feasible, use suitable respirator protection, depending on the air concentration of CMS.
Respiratory protection should be used only as part of a complete respiratory protection programme, in accordance with national standards and current best
practice.
- Conditions for safe storage, including any incompatibilities: CMS should be stored in tightly closed containers in dry, cool, well-ventilated areas. Keep CMS away from volatile chemicals.

Exposure controls / personal protection
1. Technical protection measures
Provide local exhaust or general room ventilation.
2. Organisational protection measures
Provide local exhaust or general room ventilation.
3. Hand protection
Neoprene or nitrile rubber gloves should be worn.
4. Feet protection
Wear suitable protective clothing.
5. Body protection
Wear suitable protective clothing.
6. Eye protection
Chemical googles. Contact lenses should not be used.
7. Respiratory protection
Where exposure through inhalation may occur from use, respiratory protection equipment is recommended.
Stability and reactivity
1. Reactivity
No dangerous reaction known under conditions of normal use.
2. Chemical stability
The material is considered stable under normal ambient and anticipated storage and handling conditions of temperature and pressure.
3. Possibility of hazardous reactions
No specific hazards are known.
4. Conditions to avoid
No specific hazards are known. The material is hygroscopic and exposure to high relative humidities should normally be avoided.
5. Incompatible materials
Strong oxidizing acids, Hydrogen fluoride.
6. Hazardous decomposition products
No specific hazards are known.
Disposal considerations
Use material for its intended purpose or recycle if possible. Waste must be disposed of in accordance with federal, state and local
environmental control regulations. This product normally causes no problems in sewage treatment works, where
it settles with the sewage sludge. This material is not classified as hazardous waste under EC Directive 2008/98/EC (and amendments).
