MATERIAL SAFETY DATA SHEET COMPUDOSE 100, 200 AND 400
Revision No: 4.0, 20 March 2012 STATEMENT OF HAZARDOUS NATURE: The intact Compudose implant is not considered hazardous under normal handling procedures. The following Statement of Hazardous Nature refers to the contents of the implant which contain oestradiol: Hazardous according to the criteria of Worksafe Australia: Toxic; Reproductive Category 1. R60 May impair fertility. R61 May cause harm to the unborn child. Toxic; Carcinogen Category 1. R45 May cause cancer.

Major Recommended Uses: Growth promotant implants for steers, spayed heifers and vealer heifers. For increased rate of weight gain in pastured steers including suckling steers and in spayed heifers and vealer heifers. For improved feed efficiency and increased rate of weight gain in lot fed steers and spayed heifers. Major Recommended Method(s) of Application: Subcutaneous ear implantation Section 2 - Composition / Information on Ingredients
Contains no hazardous components (one percent or greater) or carcinogens (one-tenth percent or greater) not listed above. Exposure Guidelines: Oestradiol - LEG 0.01 micrograms/m3 TWA for 12 hours. Appearance: White cylindrical silicone rubber implant Physical State: Solid Odour: Odourless Emergency Overview: Primary Physical and Health Hazards: Not hazardous if intact. Skin Permeable. Carcinogen. Highly Potent. Reproductive and Hormonal Effects. Caution Statement: The intact silicon rubber implant is not considered to be a health hazard. Compudose contains oestradiol which may enter the body through the skin, causes cancer, and is highly potent. Effects of exposure to
Page 2 of 8
the contents of Compudose may include foetal changes, decreased fertility, reproductive tissue changes, menstrual disorders, and changes in hormone levels. Routes of Entry: Inhalation and skin absorption. Potential Signs and Symptoms of Occupational Exposure: The physical nature and packaging of Compudose implants make exposure to significant quantities of the active ingredient, oestradiol, highly unlikely. There have been no reports of ill effects from handling of this device. Although no significant Elanco occupational exposures to oestradiol have been reported, increased breast size and other feminizing effects have been produced in males occupationally exposed to oestrogens. Breast enlargement and menstrual disorders have been reported in oestrogen-exposed women. Even intermittent absorption of small amounts of oestrogen through the skin may result in accumulation of relatively high systemic levels. Increased breast size in boys and pseudoprecocious puberty in girls have been observed in children born to occupationally exposed women. An accelerated skeletal maturation, strong pigmentation of the sexual organs and a feminizing syndrome in boys has also been noted in children whose parents work in oestrogen production. Other effects of exposure may include headache, nausea, vomiting, abnormal blood clotting, and increased incidence of cancer. Oestradiol is highly potent based on hormonal effects. Medical Conditions Aggravated by Exposure: Oestradiol may aggravate pre-existing oestrogen-dependent neoplasias including malignancies of the female reproductive organs and breast, thromboembolic diseases, impaired liver or kidney function, and pregnancy. Carcinogenicity: Oestradiol - IARC Group 1 (sufficient evidence of carcinogenicity in humans). NTP - Reasonably Anticipated Human Carcinogen. Not listed by ACGIH or OSHA. Remaining ingredients - No carcinogenicity data found. Not listed by IARC, NTP, ACGIH, or OSHA.

Page 3 of 8 ADDITIONAL INFORMATION PROVIDED BY MANUFACTURER: Eyes: The physical nature of Compudose implants and their packaging make injury to the eye, except by accidental mechanical means, extremely unlikely. If by remote circumstances the eyes are exposed and irritation develops, flush eyes with water and contact a physician. Skin: Oestradiol, the active ingredient in Compudose implants, is well absorbed through the skin. The physical nature of Compudose implants and their packaging eliminate exposure if proper handling instructions are followed. Remove contaminated clothing and clean before reuse. Wash all exposed areas of skin with plenty of soap and water. Get medical attention if irritation develops. Inhalation: Compudose implants present negligible human hazard through inhalation because of their physical nature and packaging. Because of the size of the implant it may cause mechanical obstruction of the airway if accidentally inhaled by a small child. If this should occur, immediately contact a physician. Ingestion: Because of the physical nature of Compudose implants, it is difficult to conceive of their presenting an acute oral hazard. If a dose is accidentally swallowed, it is estimated that 2 mg of oestradiol may be absorbed before excretion. If an adverse reaction should occur, contact a physician. Section 5 - Fire Fighting Measures
Flash Point: No applicable information found. UEL: No applicable information found. LEL: No applicable information found. Extinguishing Media: Use water, carbon dioxide, dry chemical, foam, or Halon. Unusual Fire and Explosion Hazards: None known. Hazardous Combustion Products: May emit toxic fumes when exposed to heat or fire.
Section 6 - Accidental Release Measures
Spills: If the silicon rubber implant remains intact, scoop or scrape up material into containers for disposal. If the silicon rubber implant is broken and the contents are released, contain dry material by lightly misting with water, followed by sweeping up or vacuuming. Vacuuming may disperse dust if appropriate dust collection filter is not part of the vacuum. Be aware of potential for dust explosion when using electrical equipment. Large spills due to traffic accidents, etc., should be reported immediately to Elanco Animal Health for assistance. Prevent spilled material from flowing onto adjacent
Page 4 of 8
land or into streams, ponds, or lakes. Wear protective equipment, including eye protection, to avoid exposure (see Section 8 for specific handling precautions).
Section 7 - Handling and Storage
Storage: Store below 30°C (Room Temperature).
Section 8 - Exposure Controls / Personal Protection
SPECIFIC FIRST AID INSTRUCTIONS AS PER AUSTRALIAN REQUIREMENTS: If poisoning occurs, contact a doctor or Poisons Information Centre. Phone 13 1126. ADDITIONAL INFORMATION PROVIDED BY MANUFACTURER: See Section 2 for Exposure Guideline information. Under normal use and handling conditions, no protective equipment is required. The following is recommended for a production setting: Respiratory Protection: Use an approved HEPA-filtered or supplied-air respirator. Eye Protection: Chemical goggles and/or face shield. Ventilation: Extensive local exhaust or enclosed process equipment. Other Protective Equipment: In a manufacturing setting, wear chemical- resistant gloves and body covering to minimize skin contact. If handled in a ventilated enclosure, as in a laboratory setting, respirator and goggles or face shield may not be required. Safety glasses are always required. Other Handling Precautions: CAUTION! Oestradiol is a potent drug. Avoid skin contact and inhalation. Overexposure can cause tender enlargement of the breasts and breast nodule formation in both males and females, loss of sex drive in males, and menstrual disorders in females. It has been identified as a confirmed animal carcinogen and a suspect reproductive hazard. Under normal use and handling conditions, wear goggles to protect eyes and wear impermeable gloves and protective equipment to avoid direct contact with skin. Wash thoroughly with soap and water after handling.
