SECTION 4: First-aid measures
4.1
Description of necessary first-aid measures
If inhaled
Fresh air, rest. Seek medical attention if you feel unwell.
Following skin contact
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Following eye contact
Rinse with plenty of water (remove contact lenses if easily possible).
Following ingestion
Rinse mouth. Refer immediately for medical attention.
4.2
Most important symptoms/effects, acute and delayed
Poisonous by inhalation of dust or by ingestion. Regardless of exposure route, symptoms in most cases are characteristic of severe gastritis or gastroenteritis. All chemical forms of arsenic eventually produce similar toxic effects. Symptoms may be delayed. (USCG, 1999)
4.3
Indication of immediate medical attention and special treatment needed, if necessary
Minimum/Potential Fatal Human Dose
Fatal human dose 70-180 mg depending on weight. Estimated lethal dose for a 70 kg human as As (III).
Absorption, Distribution and Excretion
Normal values of arsenic in urine, … vary from 0.013-0.046 mg/L, to 0.13 mg/L, to 0.25 mg/L. The urinary excretion, in mg/L, of elements that are freely eliminated by this route, such as … arsenic, is at most 2.5-5 times the occupation exposure in mg/cu m of air. It is apparent that biological monitoring for arsenic by urinalysis would be of limited value in determining whether or not the NIOSH recommended standard … was being met or exceeded.
SECTION 5: Fire-fighting measures
5.1
Suitable extinguishing media
If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Arsenical cmpd, liquid, NOS
5.2
Specific hazards arising from the chemical
Special Hazards of Combustion Products: Contain highly toxic arsenic trioxide and other forms of arsenic. Arsenic gas, the most dangerous form of arsenic, is produced upon contact with an acid or acid fumes. Behavior in Fire: Burns to produce dense white fumes of highly toxic arsenic trioxide. (USCG, 1999)
5.3
Special protective actions for fire-fighters
Use water spray, powder, foam, carbon dioxide.
SECTION 6: Accidental release measures
6.1
Personal precautions, protective equipment and emergency procedures
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations.
6.2
Environmental precautions

SECTION 10: Stability and reactivity
10.1
Reactivity
5 mg/cu m (as AS); NIOSH considers arsenic (inorganic cmpd, as As) to be a potential occupational carcinogen. Arsenic (inorganic cmpd, as As)
Upon heating, toxic fumes are formed. Reacts violently with strong oxidants and halogens. This generates fire and explosion hazard. Reacts with reducing agents. This produces toxic and flammable arsine gas (See ICSC 0222).
Decomposes on heating and under the influence of light and moisture. This produces toxic arsenic fumes. Reacts with strong oxidants. This generates explosion hazard. May decompose explosively on shock, friction or concussion.
10.2
Chemical stability
Loses its luster on exposure to air, forming a black modification + as2o3
10.3
Possibility of hazardous reactions
CAN BE HEATED TO BURN IN AIR WITH BLUISH FLAME, GIVING OFF AN ODOR OF GARLIC AND DENSE WHITE FUMES OF ARSENIC TRIOXIDE (AS2O3).The gas is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.ARSENIC reacts incandescently with bromine trifluoride, even at 10°C [Mellor 2:113 1946-47]. Causes bromoazide to explode upon contact. Ignites if ground up together with solid potassium permanganate [Mellor 12:322 1946-47]. Is oxidized by sodium peroxide with incandescence [Mellor 2:490-93 1946-47]. A combination of finely divided arsenic with finely divided bromates (also chlorates and iodates) of barium, calcium, magnesium, potassium, sodium, or zinc can explode by heat, percussion, and friction [Mellor 2:310 1946-47]. Bromine pentafluoride reacts readily in the cold with arsenic. Ignition usually occurs. Reacts vigorously with fluorine at ordinary temperatures [Mellor 9:34 1946-47].
10.4
Conditions to avoid
no data available
10.5
Incompatible materials
Arsine is formed when any inorganic arsenic bearing material is brought in contact with zinc and sulfuric acid.
10.6
Hazardous decomposition products
When arsenic is heated in air it will burn and form a white smoke consisting of arsenic trioxide (As2O3).

Reproductive toxicity
Inorganic arsenic Several studies have suggested that women who work in, or live near, metal smelters may have higher than normal spontaneous abortion rates, and their children may exhibit lower than normal birthweights. However, these studies are limited because they were designed to evaluate the effects of smelter pollutants in general, and are not specific for inorganic arsenic. Ingested inorganic arsenic can cross the placenta in humans, exposing the fetus to the chemical. Oral animal studies have reported inorganic arsenic at very high doses to be fetotoxic and to cause birth defects. Arsine Human studies have indicated higher than expected spontaneous abortion rates in women in the microelectronics industry who were exposed to arsine. However, these studies have several limitations, including small sample size and exposure to other chemicals in addition to arsine.
STOT-single exposure
The substance may cause effects on the gastrointestinal tract. This may result in severe gastroenteritis, loss of fluids and electrolytes, cardiac disorders, shock and convulsions. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
STOT-repeated exposure
The substance may have effects on the skin, mucous membranes, peripheral nervous system, liver and bone marrow. This may result in pigmentation disorders, hyperkeratosis, perforation of the nasal septum, neuropathy, anaemia and liver impairment. This substance is carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
Aspiration hazard
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.

Arsenic is a chemical element with the symbol As and atomic number 33.
Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.
The primary use of arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the second most commonly used semiconductor after doped silicon.
