## 3. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW

Propellant is hermetically sealed from the environment and contact is not possible without opening the inflator by destructive means. Propellant mixture in the inflator is an odorless dark pink solid. The propellant mixture is classified as a Class 1.3 Explosive and is capable of detonating under certain conditions. Protect inflator from sources of ignition, live electrical circuitry, mechanical shock, and excessive hea t. Propellant mixture may cause irritation of eyes, skin, mucous membranes, and respiratory tract. Wear appropria te personal protective equipment. Keep individuals not involved in the cleanup upwind and out of the area. If inflators are involved in a fire situation, evacuate all non-essential personnel well upwind and allow to burn unless life or property is threatened. If life or property is threatened, use large quantities of water. Do not let propellant mixture from ruptur ed inflators or runoff water enter storm or sanitary sewers, ground water or soil. Releases may be reportable to local, state, and/or federal authorities. Sodium azide is highly toxic to aquatic life.

POTENTIAL HEALTH EFFECTS: In its manufactured and sh ipped state, the propellant mixture is sealed in the inflator and there is no exposure potential. The discu ssion of the health effect presented below is for the propellant mixture. The amount of material in one inflator would not be expected to cause the effects listed under chronic and carcinogenicity.

Eye : Dusts may cause irritation, tearing, and burning of the eyes. Combustion residues are caustic and may cause severe

irritation or chemical burns.

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

chemical burns.

Skin Absorption : Not known to be absorbed through the intact skin.

Ingestion : Sodium azide may cause severe gastrointestinal irritation. May cause headache, nausea, blurred vision, shortness of breath, tachycardia (rapid heart beat), and me themoglobinemia which affects the uptake and transport of oxygen by the blood. Azides can have a severe hypotensive effe ct (lowering of the blood pressure). Initial symptoms of hemoglobin complexation (methemoglobinemia) is cyanosis which is characterized by a blue-black coloration of the lips, tongue, and mucous membranes with the skin becoming slate gray . Perchlorates and nitrates, which are converted to nitirtes in the body, may also cause methemoglobinemia.

Inhalation : Dusts may cause irritation of the nose, throat, muc ous membranes, and respiratory tract. The symptoms are similar to those discussed above for ingestion.

Chronic and Carcinogenicity : Prolonged exposures may cause dermatitis. Animal studies have shown that azides can cause nerve damage and heart and brain lesions. In-vitro test s on bacterial and mammalian cell systems have shown that azides have mutagenic activity. See Section 11.

Perchlorates can affect the utilization of iodine by the thyr oid gland. Long term, high level exposures to perchlorates may cause symptoms of thyroid dysfunction such as goiter. Ther e is also some evidence that ingestion of large quantities of perchlorates can cause kidney and lymph node damage and, in extreme cases, damage to the blood forming organs.

Pre-existing cardiovascular, respiratory, liver, kidney, sp leen, blood, 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 immediately. Seek medical attention.TRW Automotive – MSDS # 6019, Revision 3 – Page 3 of 6 – November 26, 2006 

## 4. FIRST AID MEASURES (Continued)

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

Skin : Wash thoroughly with mild soap and water. Seek medical attention if irritation develops. 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 anythi ng by mouth to an unconscious person. Treatment should be symptomatic for azide poisoning. Consult the nearest poison control center and seek medical attention.



## 5. FIRE FIGHTING MEASURES

FLASH POINT: Not Applicable LEL: 0% * UEL: 100% * AUTO IGN. TEMP.: 300 o F (149 o C)

*Self oxidizing at elevated temperatures.

Propellant is a Class 1.3 Explosive. Unless life or property is threatened, do not fight fires. The 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 or detonation. See Sections 10 and 12 concerning the reaction of az ides with acid and acidic water and the release of azides to the environment. Contain fire water if possible. Releases may be reportable to local, state, and/or federal authorities.

A self contained breathing apparatus operating in the positive pressure mode and full fire fighting gear should be worn for combating fires.



## 6. ACCIDENTAL RELEASE MEASURES

Inflators should be picked up and placed in appropriate container s. Released inflators or propellant should be picked up with anti-static tools and placed in DOT approved containers for disposal. Avoid contact with live or static electrical

sources. Avoid contact with acids. Individuals involv ed in the cleanup should wear appropriate personal protective equipment. All other personnel should be kept well clear of the area. Keep from entering storm or sanitary sewers, ground water, or soil. Releases may be reportable to federal, state, or local authorities.



## 7. HANDLING AND STORAGE

The propellant is a Class 1.3 Explosive and should be handled and stored accordingly. Do not store with or near incompatible materials cited in Section 10. Do not use or store near open flames, other source of ignition, where there is the possibility of contact with live electrical equipment or circui try, or where there is the possibility of the buildup of sta tic charges. Where dusty conditions may exist, electrically conductive floors and shoes are recommended to prevent the buildup of static charges.



## 8. EXPOSURE CONTROL - PERSONAL PROTECTION

ENGINEERING CONTROLS: Not normally required. Inflators are sealed units.

RESPIRATORY: Not normally required. If exposures may exceed the limits cited in Section 2, use, as a minimum, a NIOSH approved full facepiece respirator with R-95 or P-100 cartridges. If there is the possibility that the sodium azide component may come in contact with acids, use a NIOSH approved supplied air respirator. Consult a professional industrial hygienist or your respiratory protective equipment supplier for selection of the proper equipment. The evaluation of the need for respiratory protection should be det ermined by a professional industrial hygienist.

EYE PROTECTION: Safety glasses with sideshields are recommended.TRW Automotive – MSDS # 6019, Revision 3 – Page 4 of 6 – November 26, 2006 

## 8. EXPOSURE CONTROL - PERSONAL PROTECTION (Continued)

PROTECTIVE GLOVES: Not normally required for product. Inflators are s ealed units and there should be no exposure to the propellant mixture. Hand protecti on appropriate to the operation be ing performed should be worn.

GENERAL: No other personal protective e quipment is generally required.

## 10. STABILITY AND REACTIVITY

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

INCOMPATIBILITY (CONDITIONS TO AVOID): Azides may react with copper, silver, gold, other heavy metals, brass, bronze, and alloys containing these species to form potentia lly 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.

See Section 8.

HAZARDOUS DECOMPOSITION PRODUCTS: Thermal decomposition or combustion of the material may produce smoke, oxides of carbon, nitrogen, and iron. Acids or acid ic 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 co rrosive and should be handled with appropriate personal protective equipment to prevent skin contact.

SPECIAL SENSITIVITY: The product may self ignite at temperatures in excess of 300 o F (149 o C). The material may also be ignited by live electrical equipment and circuitry.



## 11. TOXICOLOGICAL INFORMATION

Sodium Azide: LD 50 (Rat) = 42 mg/kg; LD 50 (Rabbit, Skin) = 20 mg/kg; LD 50 (Mouse) = 27 mg/kg. Toxicology data available for the other components of the propella nt indicate that they are not highly toxic.



## 11. TOXICOLOGICAL INFORMATION (Continued)TRW Automotive – MSDS # 6019, Revision 3 – Page 5 of 6 – November 26, 2006 Sodium azide has been used as an anti-hypertensive drug. In hum an clinical trials, no adverse e ffects were reported over a 2.5 year period if dosages were kept below 0.75 mg pe r day. This is the approximate daily dos e an individual would receive if they were exposed at the ceiling exposure limit for a full workshift. The implications of animal and in-vitro tests to human health are not

known.



## 12. ECOLOGICAL INFORMATION

Sodium azide is highly toxic to aquatic life. A concentrati on of azide ion above 8 mg/L (ppm) is considered a critical concentration for fish toxicity.
