IV FIRE AND EXPLOSION H AZARDS DATA

Flash Point: N/E or N /A Method U sed: Non-flam ma ble
Explosive Lim its: Lower: N/A Upper: N/A Autoignition Temperature: N/A

Extingu ishing Media: Use suitable extinguishing media for surrounding materials and type of fire.
Special Fire Fighting Procedures: Firefighters must wear full-face, self-contained breathing apparatus with full protective clothing
to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.

Unusual Fire & Explosion Hazard: Bismuth oxide may em it toxic fumes if involved in a fire.


V HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of o ur know ledge the chem ical, ph ysical and toxicolog ical pro perties of bismu th ox ide have not b een thoro ugh ly
investigated and reported.

Bismuth and its salts can cause kidney damage, although the degree of such damage is usually mild. Large doses can be
fatal. Industrially it is considered one of the less toxic of the heavy metals. Serious and sometimes fatal poisoning may occur from
the injection of larg e doses into closed cavities and from exten sive ap plication to b urns. It is stated that the adm inistration of bism uth
should be stopped when g ingivitis appears, for otherwise serious ulceration stomatitis is likely to result. Other toxic results may
dev elop, such as a va gue feeling of bo dily d iscom fort, presen ce of albumin , or oth er pro tein substan ce in th e urin e, diarrhea, skin
reactions and sometimes serious exodermatitis. (Sax, Dangerous Properties of Industrial Materials, eighth edition)

Acute E ffects:
Inhalation: May be a nuisance dust causing respiratory irritation.
Ingestion: No acute health effects recorded.
Skin : May cause irritation.
Eye: May cause irritation.

Chro nic Effects:

Inhalation: No chronic health effects recorded.
Ingestion: Bismu th com pounds m ay cau se mild k idney dam age an d ulcerative stoma titis.
Skin : May cause dermatitis.
Eye: No chronic health effects recorded.

Target Organs: May affect the kidn eys.
Medical Conditions Generally Aggravated by Exposure: Pre-existing skin and re spiratory d isorders.

Carcino genicity: NTP: No IARC: No OSHA: No

Other: Insoluble bismuth compounds are generally considered to be of low toxicity. Chronic exposure via inhalation or ingestion
can cause the development of "bismuth line", a blue-black line of the gum as well as foul breath and excessive salivation.

EMERG ENCY AND FIRST AID PROCEDURES:

INHALATION: Remove to fresh air; keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
INGESTION: If conscious, give 1-2 glasses of milk or water and induce vomiting; keep warm and quiet; seek medical attention.
SK IN: Remov e any contam inated clothing, brush material off of skin, flush with running water, wash carefully with soap and water.
EYE: Flush with copious amounts of water for 15 minutes, seek medical attention.


VI REACTIVITY DATA

Stability: Stable

Co nditio ns to Av oid: None
Incompatibility (Materials to Avoid): Chlorine trifluoride, potassium, sodium

Haz ardous D ecomposition Produc ts: Bismuth, oxides of bismuth.
Hazardous Polymerization: Will not occur.


VII SPILL OR LEAK PROC EDURES

Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified
below. Isolate spill and provide adequate ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter
and place in a closed container fo r proper d isposal. Tak e care not to raise dust.

Waste Disposal Method: In accord ance w ith Loca l, State and Federal W aste Dispo sal Regu lations.




VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type): NIOSH approved dust-fume-m ist cartridge respirator.
Ventilation: Use local exhaust to maintain concentration at low exposure levels. General exhaust is recommended.

Protective Gloves: Rubber gloves
Eye Protection: Safety glasses

-Bismuth Oxide 2-
Other Protective Equipment: Protective gear suitable to prevent contamination.


IX SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage: Store in a cool, dry area. Store in tightly sealed container. Store away from
incompatible material. Wash thoroughly after handling.

Wo rk Practices: Imp lem ent en gineering and wo rk practice controls to re duc e and ma intain c onc entration o f exp osure at low levels.
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. Maintain eyewash capable of sustained flushing, safety drench
shower and facilities for washing.

The abo ve inform ation is believ ed to be co rrect, but do es no t purp ort to b e all inclu sive an d sha ll be used only as a gu ide.
ESPI shall not be held liab le for any d am age resulting from h and ling o r from contact with the abov e pro duc t.
