EFFECTS OF OVEREXPOSURE
*****************************************************************
This section covers the effects of
overexposure for inhalation, eye/skin contact, ingestion and
other types of overexposure information in the order of the most
hazardous and the most likely route of overexposure.
INHALATION: Animal test (rats) @ 2.7mg/1 (2,760mg/m3)
exposure for four hours produced no deaths. Gross pathological
alterations found were slight focal discoloration and slight
puffy white foci in the lungs.
ACUTE EFFECTS: (ANTIMONY OXIDE)
INHALATION: Antimony
Oxide inhalation can cause irritation to the respiratory tract
and mucous
membranes.
EYE CONTACT: Antimony Oxide was found to be
slightly to moderately irritating. Therefore, eye
contact can cause irritation and pain.
SKIN CONTACT: Antimony Oxide was found to be minimally
irritating to the skin when tested on
laboratory animals. However, human experience indicates that
prolonged or repeated
contact with skin can result in irritation and skin lesions,
sometimes referred to as
"antimony fleas". Skin irritation is worse when the skin surface
is moist as found with
perspiration.
CHRONIC EFFECTS: (ANTIMONY OXIDE)
The primary route of chronic overexposure to antimony oxide is
by inhalation.
Various studies of human overexposure to various forms of
antimony in smelters
reported effects primarily including dermatitis, rhinitis,
inflammation of the upper and
lower respiratory tract (including pneumonitis), with a few
cases of gastritis,
conjunctivitis and sepal perforation
Studies on animals exposed to Antimony tri-sulfide have been
reported to cause
changes in the heart {EKG's): however, no such reports have been
reviewed to
suggest similar alterations in EKG from exposure to antimony
trioxide.
Preliminary data from two independent chronic rat inhalation
studies revealed Antimony Oxide induced both benign and
malignant lung tumors in animal exposed for at least 12 months
to concentration, at 4.2 and 50gm/m3. Animals exposed to
1.6mg/m3. have not shown a carcinogenic response to date. The
tumors represented an unusual histological appearance from
lesions previously described in rat lungs. A high incidence of
lung fibrosis was also associated with exposure.
Antimony Oxide and Antimony compounds should be handled as
suspect carcinogens because of these findings. Antimony Oxide is
an I.A.R.C. (Group IIB) suspect carcinogen and Arsenic is an
OSHA cancer hazard, an NTP Human Carcinogen, and an I.A.R.C.
(Group I) Human Carcinogen.
AFFECTS OF ACUTE AND CHRONIC OVEREXPOSURE: (ARSENIC)
Primary Route of Entry
Inhalation
Ingestion
Skin Contact
Inhalation can cause:
Can effect the heart, liver & kidney. Toxic symptoms include
nervousness, vomiting, thirst, diarrhea, cyanosis, & collapse
Ingestion can cause:
Same as above plus GI tract irritation
Skin contact can cause:
Ulcerations
AFFECTS OF ACUTE AND CHRONIC OVEREXPOSURE: (LEAD)
Primary Route of Entry
Inhalation
Ingestion
Skin Contact
Eye Contact
Inhalation can cause:
Respiratory irritation, weakness, vomiting, loss of appetite,
loss of
coordination, convulsions, stupor coma
Ingestion can cause:
Same as above
Skin contact can cause:
Same as above
Eye contact can cause:
Sarne as above
Left untreated, can lead to weakness, insomnia, hypertension,
irritation to skin and eye, anemia, metallic taste,
constipation, headache, muscle and joint pain, neuromuscular
dysfunction, paralysis, encephalopathy, peripheral neuropathy

EMERGENCY & FIRST AID PROCEDURES
************
****************************************************
INHALATION:
Remove to fresh air. If not breathing, give artificial
respiration, preferable mouth-
to-mouth. If breathing is difficult, give oxygen. Call
physician.
SKIN CONTACT:
Flush skin with plenty of water. occurs, consult a physician. If
irritation occurs,
consult physician.
EYE CONTACT:
Flush eyes thoroughly with water for at least 15 minutes. Call a
physician.
INGESTION:
(Swallowing) Drink a quart of water. Then induce vomiting by
placing a finger far
back in the throat. Call a physician. If vomiting cannot be
induced, take
immediately to a physician or a hospital. Do not. induce
vomiting or give anything
by mouth to an unconscious person.
*****************************************************************
SPILL OR LEAK PROCEDURES
*****************************************************************
Steps to be taken if Material is
Spilled or Released: Vacuum all visible spilled material
and place in closed plastic bags for disposal: Thoroughly flush
area of spill with water. Water flush should be used only after
all visible material has been vacuumed. DO NOT flush spilled
material to sewer.
Waste Disposal Method: Care must be taken when using or
disposing of chemical materials and/or their containers to
prevent environmental contamination. It is your duty to dispose
of the chemical materials and/or their containers in accordance
with the Clean Air Act, the Clean Water Act, the Resource
Conservation and Recovery Act and all state and local
laws/regulations regarding disposal.
*****************************************************************
SPECIAL PROTECTION INFORMATION
*****************************************************************
Respiratory Protection: NIOSH/MSFili
approved dust respirator. Respiratory program must be in
accordance with 29CFR 1910.134.
Ventilation Type:
Local Exhaust-Sufficient to maintain employee exposure as far
below OSHA
permissible exposure limits as practical.
Eye Protection:
Chemical Safety Goggles. Gloves: Rubber, Neoprene or Nitrile.
Other Protective Equipment: Long-sleeved shirt, eye-wash
fountain and safety shower in immediate area. Personnel
protective clothing and use of equipment must be in accordance
with 29CFR 1910.133.
*****************************************************************
SPECIAL PRECAUTIONS
*****************************************************************
Precautions to be taken during handling
and storing:
(1) When handling, wear long -sleeved shirt,
rubber gloves and chemical safety goggles.
(2) Wear respiratory protection where potential
exposure to dust may occur. ,
(3) Respiratory protection must be NIOSH/MSHA-
approved for protection against dust
(4) Store in a dry, well-ventilated area.
(5) Do not store in open, unlabeled or mislabeled
containers.
Other precautions:
(l) Do not inhale dust. Inhalation may cause
irritation of respiratory tract and mucous membranes.
Long-term
exposure may cause irreversible lung changes and other health
effects.
(2) Use only with adequate ventilation.
Ventilation must be sufficient to limit employee exposure to
antimony
oxide in work area as far below OSHA permissible exposure limit
as practical.
(3) Avoid contact with eyes. May cause irritation
and pain.
(4) Do not take internally.
(5) Do
net eat or drink in work area.
(6) Wash thoroughly after handling
and take shower at end of work shift. Wear clean clothing daily.
