HEALTH & SAFETY INFORMATION
• IDLH:
5
mg[As]/m3 (inorganic compounds).
•
IARC:
Group 1, known human carcinogen; human
evidence, sufficient.
•
NTP:
Known human carcinogen. Several studies have
shown that inorganic arsenic can increase the risk of lung cancer, skin cancer,
bladder cancer, liver cancer, kidney cancer, and prostate cancer. The World
Health Organization (WHO), the U. S. Department of Health and Human Services,
and the EPA have determined that inorganic arsenic is a human carcinogen.
•
OSHA Specifically Regulated Substances (29 CFR 1910.1018) as inorganic arsenic.
•
Breathing high levels of inorganic arsenic can give you a sore throat or
irritated lungs. Ingesting high levels of inorganic arsenic can result in
death. Lower levels of arsenic can cause nausea and vomiting, decreased
production of red and white blood cells, abnormal heart rhythm, damage to
blood vessels, and a sensation of “pins and needles” in hands and feet.
Ingesting or breathing low levels of inorganic arsenic for a long time can
cause a darkening of the skin and the appearance of small “corns” or “warts” on
the palms, soles, and torso. Skin contact with inorganic arsenic may cause
redness and swelling. Organic arsenic compounds are less toxic than inorganic
arsenic compounds. Exposure to high levels of some organic arsenic compounds
may cause similar effects as inorganic arsenic. Also changes in carbohydrate metabolism
and peroxide levels, and increased systolic blood pressure may be detected in
exposed workers. There has been an increase of chromosomal abnormalities in
workers exposed to arsenic.
Exposure Limits:
•
ACGIH TLV: 0.01 mg[As]/m3 TWA; confirmed human carcinogen
•
OSHA PEL: 0.010 mg[As]/m3 TWA; cancer hazard that can be inhaled
•
NIOSH REL: 0.002 mg[As]/m3 15 min. ceiling limit. Reduce exposure to lowest
feasible level.
Respirator:
At
any concentrations above the NIOSH REL, or where there is no REL, at any
detectable concentration:
SCBAF:PD,PP
(any self-contained breathing apparatus that has a full faceplate and is
operated in a pressure-demand or other positivepressure mode)
P
SAF:PD,PP:ASCBA (any suppliedair respirator that has a full
facepiece and is operated in a pressure-demand or other positive-pressure mode
in combination with an auxiliary self-contained breathing apparatus operated in
a pressure-demand or other positive-pressure mode).
Escape:
GMFAGHiE (any air-purifying, full-facepiece
respirator (gas mask) with a chin-style, front- or back-mounted acid gas
canister having a high-efficiency particulate filter)
P
SCBAE (any appropriate escape-type, self-contained breathing
apparatus).
Reactivity:
Incompatible
with strong acids, strong oxidizers, peroxides, bromine pentafluoride, bromine
trifluoride, cesiumacetylene carbide, chromium trioxide, nitrogen trichloride,
and silver nitrate. Hydrogen gas can react with inorganic arsenic to form
highly toxic arsine gas. Forms highly toxic fumes on contact with acids or
active metals (aluminum, iron, and zinc).
FIRE INFORMATION:
Noncombustible solid in bulk form, but a slight explosion hazard
in the form of dust when exposed to flame. If material or contaminated runoff
enters waterways, notify downstream users of potentially contaminated water.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Do not use mouth-to-mouth method if victim ingested
or inhaled the substance; induce artificial respiration with the aid of a
pocket mask equipped with a one-way valve or other proper respiratory medical
device. Administer oxygen if breathing is difficult. Remove and isolate
contaminated clothing and shoes. In case of contact with substance, immediately
flush skin or eyes with running water for at least 20 minutes. For minor skin
contact, avoid spreading material on unaffected skin. Keep victim warm and
quiet. Effects of exposure (inhalation, ingestion, or skin contact) may be
delayed. Ensure that medical personnel are aware of the material(s) involved,
and take precautions to protect themselves.
