Section 1: Product Identification Chemical Name: Diethylzinc, min. 95% (Material sold in non-returnable cylinder) Product Number: 93-3030 CAS Registry Number: 557-20-0 Formula: Zn(C2H5)2 EINECS Number: 209-161-3 Chemical Family: metal alkyl Synonym: zinc, diethyl

Section 2: Composition and Information on Ingredients Ingredient CAS Number Percent ACGIH (TWA) OSHA (PEL) Title Compound 557-20-0 100% 5 mg/m3 (fume) 5 mg/m3 (fume)

Section 3: Hazards Identification Inhalation of zinc oxide fume produced from this compound in a fire may cause metal fume fever or zinc Emergency Overview: shakes consisting of chills, fever, muscular pain, nausea, and vomiting. May cause thermal burns. Primary Routes of Exposure: Eyes, skin, and inhalation of combustion products. Eye Contact: Direct contact of liquid with the eyes will cause thermal burns and possible blindness. Skin Contact: Liquid bursts in to flame in air, causing thermal burns to skin. Fume causes burns to the nose, mucous membranes and respiratory tract causing metallic taste, dry throat, Inhalation: and chills. Ingestion: Ingestion is an unlikely mode of entry as the material is pyrophoric. Acute Health Affects: Causes burns to skin, eyes and respiratory tract. Inhalation may cause chills and nausea. No serious long-term chronic effects associated with zinc compounds. Prolonged inhalation may cause Chronic Health Affects: laryngitis. Prolonged ingestion may cause constipation. NTP: No IARC: No OSHA: No

SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with a large volume of water applied rapidly. Remove contaminated clothes if Skin Exposure: necessary. Seek medical assistance if irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel.
