Section II - Chemical Data
────────────────────────────────────────────────────────────
Chemical Family: Calcium Salts
Formula: Portland cement consists of finely ground portland cement clinker mixed with a small amount of calcium sulfate to control set. Portland cement clinker is a sintered material produced by heating to high temperature (greater than 1,200 degrees Celsius) a mixture of substances such as limestone and shale from the earth's crust. The substances manufactured are essentially hydraulic calcium silicates contained in a crystalline mass, not separable into the individual components.
Substances similar to the following are known to be present in portland cement:
3Ca0.Si02 (CAS #12168-85-3)
2Ca0.Si02 (CAS #10034-77-2)
3Ca0.A1203 (CAS #12042-78-3)
4Ca0.A1203.Fe203 (CAS #12068-35-8)
CaS04.XH20 (CAS #13397-24-5)
Small amounts of Ca0, Mg0, K2S04, Na2S04 may also be present.

Section III - Hazardous Ingredients
─────────────────────────────────────────────────────────────
Ingredients: Portland cements are listed by OSHA in 29 CFR 1910.1000, Table Z-1-A, and require Material Safety Data Sheets (FR, January 19, 1989). MSHA (30 CFR 55.5.-1, Ref. 2), ACGIH (TLV's for 1973, Appendix E) and ACGIH (TLV's for 1984-5, Appendix D) list portland cements as nuisance dusts. Portland cements are NOT listed by NTP, IARC, or OSHA as carcinogens. However, since portland cement is manufactured from raw materials mined from the earth (limestone, marl, sand, shale, clay, etc.) and process heat is provided by burning fossil fuels, trace, but detectable, amounts of naturally occurring elements may be found during chemical analysis.

Section VI - Health Hazard Data
─────────────────────────────────────────────────────────────
ACGIH Threshold Limit Value (1988-89): Total dust containing
no asbestos and less than 1% silica - 10 mg/m3
OSHA PEL (Transitional): Total Dust - 50 Million Particles/ft3
OSHA PEL (Final): Total Dust - 10 mg/m3
Respirable Dust - 5 mg/m3
Effects of Overexposure:
Acute: Wet cement, especially as an ingredient in plastic (unhardened) concrete, mortar or slurries, can dry the skin and
may irritate the eyes upon contact. Wet cement may cause severe caustic burns to the eyes or skin. Inhalation can irritate the upper respiratory system.
Chronic: Cement dust can cause inflammation of the lining tissue of the interior of the nose and inflammation of the cornea. Hypersensitive individuals may develop an allergic dermatitis.
[Cements may contain trace (less than 0.05%) amounts of chromium salts or compounds including hexavalent chromium, or other metals found to be hazardous or toxic in some chemical forms. These metals are mostly present as trace substitutions within the principal minerals.]
Emergency and First Aid Procedures: Irrigate eyes immediately and repeatedly with water and get prompt medical attention. Wash exposed skin areas with soap and water. Apply sterile dressings. If ingested, consult a physician immediately. Drink water.

Section VII - Reactivity Data
─────────────────────────────────────────────────────────────
Stability: Product is stable. Keep dry until used.
Incompatibility: If wet mortar or concrete comes in contact with an outside source of aluminum powder or other alkali and alkaline earth elements, hydrogen gas may be liberated.
Hazardous Decomposition Products: None
Hazardous Polymerization: Will not occur.
────────────────────────────────────────────────────────────
Section VIII - Spill Procedures
────────────────────────────────────────────────────────────
Steps to be Taken in Case Material is Spilled: Use dry cleanup methods that do not disperse the dust into the air. Avoid breathing the dust. Emergency procedures are not required.
Disposal Method: Small amounts of material can be disposed of as common waste or returned to the container for later use if it is not contaminated. Large volumes may require special handling.
─────────────────────────────────────────────────────────────
Section IX - Special Protection Information
─────────────────────────────────────────────────────────────
Respiratory Protection: In dusty environments, the use of a
MSHA/NIOSH-approved respirator is recommended.
Ventilation: Local exhaust can be used to control airborne dust levels.
Eye Protection: Use tight fitting goggles in dusty environments.
Skin Protection: Use barrier creams, impervious, abrasion-and alkali- resistant gloves, boots and protective clothing to protect the skin from prolonged contact with wet cement in plastic concrete, mortar or slurries. Immediately after working with cement or cement-containing materials, workers should shower with soap and water. Precautions must be taken. Cement burns with little warning - little heat is sensed.
