Section 3 - Hazards Identification


Appearance: white crystalline powder. Flash Point: 62 deg C.
Danger! Flammable solid. Causes severe eye irritation and possible eye injury. Causes skin and respiratory tract irritation. May be harmful if swallowed, inhaled, or absorbed through the skin. Hygroscopic (absorbs moisture from the air). Sublimes (goes directly from solid to vapor form) readily at room temperature.
Target Organs: Central nervous system, respiratory system, eyes, skin.

Potential Health Effects
Eye: Contact with eyes may cause severe irritation, and possible eye burns. Vapors cause eye irritation. A single exposure to TEDA vapor can cause slight swelling of the front part of the eye (cornea). This may result in a "halo" vision effect beginning up to several hours after exposure. Symptoms include hazy, foggy and sometimes blurry vision, and seeing blue halos around lights. Recovery usually occurs within a day. It is not certain what levels of TEDA vapor cause this effect. corneal injury occurred when 0.5 ml of a solution of 5% TEDA in water was applied to rabbit eyes. A 15% solution caused moderate injury, and a 25% solution burned the eyes.
Skin: Causes skin irritation. May be harmful if absorbed through the skin. Definite skin reddening and some death of skin tissue were seen 24 hours after a solution of 25% TEDA in water was applied to rabbit skin. When a solution of 10% TEDA in water was applied to the skin of 5 mice for 2 weeks, 2 of the mice died from bleeding in the prostate gland. Two other mice also had bleeding of the prostate gland but did not die. There was no sign of skin damage .
Ingestion: May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. The toxicological properties of this substance have not been fully investigated. May be harmful if swallowed.
Inhalation: Inhalation of vapor may cause respiratory tract irritation. Inhalation of dust may cause respiratory tract irritation. Acute inhalation toxicity was evaluated in guinea pigs exposed to triethylenediamine at a measured concentration of 8.9 ppm for a period of 1 hour. Clinical observations included slight dyspnea and somewhat elevated airway resistance. (Olin Corp.)
Chronic: No information found.

Section 4 - First Aid Measures

Eyes: Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed. Extensive irrigation with water is required (at least 30 minutes).
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Flammable solid.
Extinguishing Media: Use water spray, dry chemical, or carbon dioxide.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Keep away from heat, sparks and flame. Avoid breathing dust. Do not get in eyes. Avoid contact with skin and clothing.
Storage: Keep away from sources of ignition. Store in a tightly closed container. Refrigerator/flammables. Isolate from oxidizing materials and acids.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels.
