General Measures: Remove patient from area of exposure.

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

INGESTION: Rinse mouth with water. Do not induce vomiting. Seek medical attention. Never induce vomiting or give anything by  mouth to an unconscious person.

SKIN: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Seek medical attention.

EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention.

Most Important Symptoms/Effects, Acute and Delayed: May cause severe irritation and burns. See section 11 for more information.

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




Extinguishing Media: Use suitable extinguishing agent for surrounding materials and type of fire..

Unsuitable Extinguishing Media: No information available.

Specific Hazards Arising from the Material: May release toxic fumes if involved in a fire.

Special Protective Equipment and Precautions for Firefighters: Wear full face, self-contained breathing apparatus and full protective clothing.




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: Avoid creating dust. Scoop or vacuum up spill using a vacuum system equipped with a high efficiency particulate air (HEPA) filtration system and place in a properly labeled closed container for further handling and disposal.

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




Precautions for Safe Handling: Handle in an enclosed, controlled process. 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: Store in a cool, dry area. Store material tightly sealed in properly labeled containers. Protect from moisture. Store away from oxidizers or acids. See section 10 for more information on incompatible materials.




Exposure Limits:             OSHA/PEL:                              ACGIH/TLV:

Iron salts, soluble, as Fe     No exposure limit established      1 mg/m3

Fluorides (as F)                  2.5 mg/m3                                2.5 mg/m3

Engineering Controls: 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. Use good housekeeping and sanitation practices. 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.

Individual Protection Measures, Such as Personal Protective Equipment:

  Respiratory Protection: Use suitable respirator when dust or fumes are present.

  Eye Protection: Safety glasses

  Skin Protection: Impermeable gloves, protective work clothing as necessary.

Possibility of Hazardous Reactions: On contact with acids may emit toxic fumes of fluorine.

Conditions to Avoid: Heat, sparks, flame, dusting conditions.

Incompatible Materials: Acids, oxidizing agents, water/moisture.

Hazardous Decomposition Products: Iron oxide fume, hydrogen fluoride.




Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May cause strong irritation to lungs, skin and eyes.

Acute and Chronic Effects:

Iron Compounds/Iron Salts:  Irritating to the respiratory tract, iron compounds may cause pulmonary fibrosis if dusts are inhaled. Inhalation of large amounts may cause iron pneumoconiosis. Inhalation of ferric salts as dusts & mists is irritating to the respiratory tract. Ferric salts are regarded as skin irritants.

Inorganic Fluorides:  Acute effects resulting from exposure to inorganic fluorides are mainly due to the effects of hydrogen fluoride, a colorless gas or liquid. The major health effect of chronic inhalation exposure to fluoride compounds is skeletal fluorosis, which has been reported in cases of exposure to fluoride dusts and hydrogen fluoride, either individually or in combination. Excluding sodium fluoride, effects of exposure to inorganic fluoride compounds has not been well studied. Based on single exposure animal tests, sodium fluoride is considered to be moderately toxic if swallowed, no more than slightly toxic if absorbed through the skin, slightly irritating to skin and corrosive to eyes.
