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.

 

 

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. 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. Do not store together with oxidizers. See section 10 for more information on incompatible materials.

 

 

8   EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits:                                OSHA/PEL:     ACGIH/TLV:

Arsenic, inorganic compounds (as As)     0.01 mg/m3     0.01 mg/m3

Engineering Controls: Handle in an enclosed, controlled process. Ensure adequate ventilation to maintain exposures below occupational limits. 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. Clothing worn in areas of exposure to dust or fume should be restricted to the workplace and laundered regularly.

Individual Protection Measures, Such as Personal Protective Equipment:

   Respiratory Protection: NIOSH approved respirator.

   Eye Protection: Safety glasses

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

11   TOXICOLOGICAL INFORMATION

Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May cause irritation to skin and eyes and systemic poisoning with symptoms including abdominal pain, nausea, vomiting, diarrhea, and peripheral neuropathy.

Acute and Chronic Effects:

Arsenic Compounds: Arsenic compounds are mainly absorbed through the gastrointestinal tract, but some absorption may occur through intact skin or inhalation. Acute arsenic ingestion generally produces signs and symptoms within 30 minutes but symptoms may be delayed for several hours if ingested with food. Effects include vomiting, abdominal pain and diarrhea, followed by numbness and tingling of the extremities, muscle cramping, and death, in extreme cases. The first signs of long-term exposure to high levels of inorganic arsenic are usually observed in the skin, and include pigmentation changes, skin lesions, and hard patches on the palms and soles of the feet (hyperkeratosis). Cases of acute arsenical poisoning due to inhalation are exceedingly rare in industry. Increased mortality from multiple internal organ cancers (liver, kidney, lung, and bladder) and an increased incidence of skin cancer have been observed in populations consuming drinking water high in inorganic arsenic, and increased lung cancer mortality is associated with populations exposed primarily through inhalation.
