General Measures: Remove patient from area of exposure.

INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek immediate medical attention.

INGESTION: Quickly wipe material from mouth and rinse with water. Do not induce vomiting. Seek medical attention immediately.

SKIN: Remove contaminated clothing if necessary. Remove as much material from skin as possible by wiping with a dry cloth, then wash the affected area with large amounts of water until all material is removed. Seek medical attention.

EYES: Immediately flush eyes with copious amounts of water, including under eyelids for at least 10-15 minutes. A victim may need assistance in keeping their eyelids open. Seek immediate medical attention.

Most Important Symptoms/Effects, Acute and Delayed: May cause respiratory irritation, cough and difficulty in breathing if inhaled. May cause redness, pain and possible burns to eyes and skin. See section 11 for more information.

Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.




Extinguishing Media: Use Class D dry powder extinguishing agent.

Unsuitable Extinguishing Media: Do not use water, foam, carbon dioxide or halogenated extinguishers.

Specific Hazards Arising from the Material: Material readily reacts with water generating flammable hydrogen gas. May emit fumes of calcium oxide and/or calcium hydroxide under fire conditions.

Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.




Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes. Eliminate all sources of ignition.

Methods and Materials for Containment and Cleaning Up: Scoop dry solids into a dry metal container, properly label and cover. Do not use water for spill clean-up. Use only non-sparking tools and natural bristle brushes.

Environmental Precautions: Do not allow to enter drains or to be released to the environment.




Precautions for Safe Handling: Handle under dry protective gas such as argon. Handle in an enclosed, controlled process. Do not allow contact with water. Protect from sources of ignition. Avoid creating dust. Avoid breathing dust or fumes. Provide adequate ventilation if dusts are created. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.

Conditions for Safe Storage, Including Any Incompatibilities: Store in tightly-sealed containers under argon or mineral oil. Store in properly labeled containers. Protect from water/moisture. Storage area should be free of combustibles and ignition sources. See section 10 for more information on incompatible materials.




Exposure Limits:     Calcium

OSHA/PEL:               No exposure limit established

ACGIH/TLV:             No exposure limit established

Appropriate Engineering Controls: Handle in an enclosed, controlled process under dry argon. Use local exhaust to maintain exposure at low levels. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air. Prepare for the possibility of a fire. Keep extinguishing agents, tools for handling and protective clothing readily available.

Individual Protection Measures, Such as Personal Protective Equipment:

Respiratory Protection: Wear a NIOSH/MSHA approved respirator when high concentrations are present.

Eye Protection: Always wear approved chemical splash proof goggles.

Skin Protection: Rubber gloves, flame retardant protective work clothing.

Possibility of Hazardous Reactions: Reacts readily with water releasing flammable hydrogen gas. Contact with alkali hydroxides or carbonates may cause detonation.

Conditions to Avoid: Contact with air or water.

Incompatible Materials: Water, moist air, oxidizing agents, acids, halogens, alcohols, asbestos cement, lead dichloride, phosphorus pentoxide, silicon, sodium, oxides, sulfur.

Hazardous Decomposition Products: Calcium oxides, hydrogen gas, calcium hydroxide.




Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May cause respiratory irritation, cough, difficulty in breathing, and chemical pneumonitis if inhaled, irritation or burns to the mouth, throat, and stomach if swallowed. May cause vomiting. Contact with skin will cause irritation and possible corrosion damage. Substance is severely irritating to the eyes and may injure eye tissue if not promptly removed.

Acute and Chronic Effects: Calcium will react with water or moisture causing heat. If calcium metal contacts moisture in the eyes, on the skin, or in the respiratory tract, severe corrosive irritation may result. The fumes evolved by burning calcium in air are composed of calcium oxide which is an irritant to the skin, eyes and mucous membrane. Generally speaking, calcium compounds should be considered toxic only when they contain toxic components or as calcium oxide or hydroxide. Calcium compounds are common air contaminants.
