Chemical Identifiers

The Chemical Identifier fields include common identification numbers, the NFPA diamond, U.S. Department of Transportation hazard labels, and a general description of the chemical. The information in CAMEO Chemicals comes from a variety of data sources..
CAS Number UN/NA Number DOT Hazard Label USCG CHRIS Code
  • 12002-03-8
  • Poison
NFPA 704

NIOSH Pocket Guide International Chem Safety Card
Arsenic (inorganic compounds, as As)external link none
General Description
An emerald-green powder. Usually contains some water. Insoluble in water. Toxic by inhalation and by ingestion. Used as a wood preservative, insecticide, and pigment.

Hazards

The Hazard fields include special hazard alerts, air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
none
Air & Water Reactions
Insoluble in water. Decomposes on prolonged heating in water [Merck].
Fire Hazard
Poisonous, volatile arsenic oxide may be formed in fires. Exposure of dust to flame may cause explosion. When heated, or on contact with acid or acid fumes, it emits highly toxic fumes. Decomposes readily in the presence of water and carbon dioxide to yield phytotoxic arsenical compounds. Can react vigorously with oxidizing materials. Unstable in acids and bases. Hazardous polymerization may not occur. (EPA, 1998)
Health Hazard
This material is extremely toxic; the probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and 1 teaspoonful for a 150-lb. person. Some absorption may occur through the skin and by inhalation, but most poisonings result from ingestion. It may cause eye and respiratory tract irritation. Industrial exposure may cause dermatitis. (EPA, 1998)
Reactivity Profile
COPPER ACETOARSENITE is soluble in acids. Is unstable in acids, bases and toward hydrogen sulfide [Merck]. Has weak oxidizing or reducing powers. Redox reactions can however still occur.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Response Recommendations

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]:

As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)
Firefighting
Stay upwind; keep out of low areas. Wear self-contained (positive pressure if available) breathing apparatus and full protective clothing.

For small fires, use dry chemical, water spray, or foam. For large fires, use water spray, fog, or foam. Use of water may result in generation of toxic fumes. (EPA, 1998)
Non-Fire Response
Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]:

Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2016)
Protective Clothing
For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

First Aid
Warning: Ingestion generally produces symptoms within 30 minutes but may be delayed for several hours. Caution is advised.

Signs and Symptoms of Paris Green Exposure: Acute exposure to Paris green may include dizziness, headache, a sweetish, metallic taste and garlic odor to breath and feces, difficulty in swallowing, abdominal pain, vomiting, diarrhea, and dehydration. Rapid heart beat, acute hemolysis (red blood cell breakdown), altered mental status, muscle cramps, seizures, toxic delirium, convulsions, and coma may also be noted.

Emergency Life-Support Procedures: Acute exposure to Paris green may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.

Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to Paris green.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
4. Transport to a health care facility.

Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self-exposure to Paris green.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Remove and isolate contaminated clothing as soon as possible.
4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes.
5. Wash exposed skin areas thoroughly with soap and water.
6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
7. Transport to a health care facility.

Ingestion Exposure:
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
2. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
3. Give the victims water: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Water should be given only if victims are conscious and alert.
4. Transport to a health care facility. (EPA, 1998)
