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

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

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

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

 

 

5   FIREFIGHTING MEASURES

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 emit toxic metal oxide fumes under fire conditions.

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

 

 

6   ACCIDENTAL RELEASE MEASURES

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 raising dust. Scoop or vacuum up using a vacuum system equipped with a HEPA filter. Place in properly labeled closed containers.

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

 

 

7   HANDLING AND STORAGE

Precautions for Safe Handling: Handle in an enclosed, controlled process. Avoid creating dust. Provide adequate ventilation if dusts are created. Avoid breathing dust or fumes. 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 a cool, dry, well-ventilated area. Store in a tightly sealed container. See section 10 for more information on incompatible materials.

 

 

8   EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits:                            OSHA/PEL:                              ACGIH/TLV:

Chromium Silicide                             No exposure limit established     No exposure limit established

Chromium (III) compounds (as Cr)    0.5 mg/m3                                0.5 mg/m3

Appropriate 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: Wear a NIOSH/MSHA approved respirator when dust or fumes are present.

   Eye Protection: Safety glasses

   Skin Protection: Wear impermeable gloves, protective work clothing as necessary.

11   TOXICOLOGICAL INFORMATION

Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May cause irritation if inhaled. Dusts may irritate skin and eyes.

Acute and Chronic Effects:

Chromium Compounds: The physiological responses to chromium and its compounds varies widely because of the different toxicological potentials associated with each of the 3 chromium valencies (2+, 3+, 6+). Further, within each valency group, toxicity varies according to solubility. Chromate salts are suspected human carcinogens. Chromic acid and its salts have a corrosive action on the skin and mucous membranes. Hexavalent compounds are more toxic than the trivalent.

Silicon Compounds: Silicon dioxide is chemically and biologically inert when ingested, however heavy exposure to freshly formed silica fume may cause an acute reaction similar to metal fume fever. Silicon carbide is considered to be a nuisance particulate. Chlorosilanes, considered non-corrosive in their dry state, may become corrosive when in contact with water or moisture of skin and mucous membranes.

Acute Toxicity: No data

Carcinogenicity:

Chromium and certain chromium compounds: NTP: K - Known to be carcinogenic   IARC: Not identified as carcinogenic

To the best of our knowledge the chemical, physical and toxicological characteristics of the substance are not fully known.
