## 3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW

Product is a flammable solid. It is deep pink grains with no odor. Remove all sources of ignition and live electrical circuit ry. May cause irritation of eyes, skin, mucous membranes, and respir atory tract. May be absorbed through the intact skin. Wear

appropriate personal protective equipment. Keep individuals not involved in the cleanup out of the area. If product is involv ed in a

fire situation, evacuate all non-essential personnel well upwind a nd allow to burn unless life or property is threatened. If l ife or

property is threatened, use large quantities of water. Do not let product or runoff water enter storm or sanitary sewers, grou nd

water or soil. Sodium azide is highly toxic to aquatic life. Specific cleanup and disposal pr ocedures should be obtained from

Chemtrec (1-800-424-9300).

POTENTIAL HEALTH EFFECTS:

Eye : May cause irritation, tearing, and burning of the eyes. Co mbustion residues are caustic and may cause severe irritation or

chemical burns.

Skin Contact : May cause irritation of the skin. Combustion residues are caustic and may cause severe irritation or chemical burns.

Skin Absorption : Sodium azide can be absorbed through the intact skin. The symptoms are similar to those discussed below for

ingestion.

Ingestion : Sodium azide may cause severe gastrointestinal irritation. May cause headache, nausea, blurred vision, shortness of

breath, tachycardia (rapid heart beat), and methemoglobinemia which affects the uptake and transport of oxygen by the blood.

Azides can have a severe hypotensive effect (lowering of the bl ood pressure) Nitrates can be converted into nitrites which can also

cause methemoglobinemia.

Initial symptoms methemoglobinemia is cyanos is which is characterized by a blue-black coloration of the lips, tongue, and mucou s membranes, with the skin becoming slate gray.

Inhalation : May cause irritation of the nose, throat, mucous membranes, and respiratory tract. The symptoms are similar to those

discussed above for ingestion.

Chronic and Carcinogenicity : Prolonged dermal exposures may cause dermatitis. Animal studies have shown that azides can cause

nerve damage and heart and brain lesions. In-vitro tests on b acterial and mammalian cell systems have shown that azides have

mutagenic activity. See Section 11. Exposures to high concen trations of ferric oxide, Benton ite, and graphite over prolonged

periods of time, as with any particulate matte r may cause an impairment of lung function.

Perchlorates can affect the use of iodine by the thyroid gla nd. Long term, high level exposur es to perchlorates may cause

symptoms of thyroid disfunction such as goiter. Perchlorates may also convert hemoglobin to methemoglobin and block the oxygen

transport mechanism of the blood. There is also some evidence that ingestion of large quantities of perchlorates can cause kid ney and lymph node damage and, in extreme cas es, damage to the blood forming organs.

Pre-existing cardiovascular, respiratory, ki dney, thyroid, respiratory, and dermal disorders may possibly be aggravated by

exposure to the components of the product.

The components of the product are not known to be carcinogens or potential carcinogens.

## 4. FIRST AID MEASURES

Inhalation : Remove exposed person to fresh air. If breathing is difficult, oxygen may be administered. If breathing has stopped,

artificial respiration should be started i mmediately. Seek medical attention.

Eyes : Flush with tepid water for at least 20 minutes holding the eye lids wide open. Seek medical attention if irritation develops or persists.

Skin : Wash thoroughly with mild soap and water. Seek medical atte ntion if irritation develops or if symptoms of azide poisoning

develop. Remove any contaminated clothing and launder thoroughly before reuse.

Ingestion : Not expected to be an important route of entry into the body. If large amounts of the product are ingested, give 2

glasses of water and induce vomiting. Never give anything by mout h to an unconscious person. Treatment should be symptomatic

for azide and/or nitrite poisoning. Consult the near est poison control center and seek medical attention.



## 5. FIRE FIGHTING MEASURES

FLASH POINT: Not Applicable LEL: 0% * UEL: 100% * AUTO IGN. TEMP.: 570 o F (300 o C)

*Self-oxidizing at elevated temperatures.

Unless life or property is threatened, do not fight fires. Th e area should be evacuated and all personnel kept well upwind.

Material near fires should be cooled with a water spray or fog to prevent ignition. Do not let runoff water enter storm or san itary

sewers, ground water or soil. See Sections 10 and 12 concerni ng the reaction of azides with acid and acidic water and the rel ease

or azides and nitrates to the environment.

A self-contained breathing apparatus operating in the positive pre ssure mode and full fire fighting gear should be worn for

combating fires.



## 6. ACCIDENTAL RELEASE MEASURES

If product is spilled or released eliminate all sources of ignition and live electrical circuitry. Individuals involved in the cleanup

should wear appropriate personal protective e quipment. All other personnel should be kept well clear of the area. Pick up rel eased

material with anti-static tools and place in DOT approved containe rs for disposal. Keep from entering storm or sanitary sewers

, ground water, or soil. Releases may be reportabl e to federal, state, or local authorities.



## 7. HANDLING AND STORAGE

Store in a cool dry environment away from incompatible material s cited in Section 10. Do not use or store near open flames, ot her

source of ignition, where there is the possibility of contact with live electrical equipment or circuitry, or where there is th e possibility of the buildup of static charges. Where dusty c onditions may exist, electrically conductive floors and shoes are

recommended to prevent the buildup of static charges. Appropriate personal protectiv e equipment cited in Section 8 should be

worn during handling.



## 8. EXPOSURE CONTROL - PERSONAL PROTECTION

ENGINEERING CONTROLS: Local exhaust ventilation should be provided to maintain exposures below the limits cited in

Section 2. Design details for local exhaust ventilation system s may be found in the latest edition of "Industrial Ventilation: A

Manual of Recommended Practice" published by the ACGIH Committ ee on Industrial Ventilation, P.O. Box 16153, Lansing, MI

48910. The need for local exhaust ventilation should be evaluate d by a professional industrial hygienist. Local exhaust venti lation

systems should be designed by a professional engineer.

## 10. STABILITY AND REACTIVITY

STABILITY & POLYMERIZATION: Product is stable. Hazardous polymerization will not occur.

INCOMPATIBILITY (CONDITIONS TO AVOID): Azides may react with copper, silv er, gold, other heavy metals, brass,

bronze, and alloys containing these species to form potentially explosive metal azides. Strong oxidizing agents may initiate

ignition. Reaction with acids or acidic water will liberate hydrazoic acid (HN 3 ), which is highly toxic and explosive.

HAZARDOUS DECOMPOSITION PRODUCTS: Thermal decomposition or combusti on may product dense smoke, oxides of

nitrogen, and fumes of iron and silicon. Ac idic water may react with sodium azide to form highly toxic and explosive hydrazoic

acid (HN 3 ).

Ignition of the product will form small amounts of sodium metal and sodium oxide, which will form sodium hydroxide on contact

with water. Sodium hydroxide is potentially corrosive and shoul d be handled with appropriate personal protective equipment to

prevent skin contact.

SPECIAL SENSITIVITY: The product may self ignite at temperatures in excess of 570 o F (300 o C). The material may also be

ignited by live electrical equipment and circuitry. Graphite is electrically conductive. Accumulations of dust may cause shor ting of

electrical circuits. Care should be taken to seal electrical ci rcuits and switches that may be affected. Dusts should not be emitted to

the atmosphere where they may settle on and potentially cause shorting of outside electrical equipment.

## 11. TOXICOLOGICAL INFORMATION

Sodium Azide: LD 50 (Rat) = 42 mg/kg

L D 50 (Rabbit, Skin) = 20 mg/kg

Sodium azide has been used as an anti-hypertensive drug. In human clinical trials, no adverse effects were reported over a 2.5 year period if dosages were kept below 0.75 mg per day. This is th e approximate daily dose an individual would receive if they were

exposed at the ceiling exposure limit for an entire workshift. T hus, the implications of animal and in-vitro tests to human he alth are

not known.

The other components of the product have much lower acute toxicities than does sodium azide. The LD 50 s for the other

components range from 1,870 mg/kg for potassium perchlorate to greater tha 5,000 mg/kg for gr aphite and amorphous silica.



## 12. ECOLOGICAL INFORMATION

Sodium azide is highly toxic to aquatic life. A concentration of azide ion above 8 mg/L (ppm) is considered a critical concent ration

for fish toxicity. High concentrations of nitrates can cause the eutrophication of lakes and other bodies of water.
