| First Aid Measures | Back to Contents | 【Ingestion】
Emesis is contraindicated in patients with a prolonged pt or inr due to the risk of bleeding following ipecac-induced increased intracranial pressure. Ipecac may be indicated in the home setting for pediatric patients with an accurate history of recent one-time acute ingestion of these rodenticides. Emesis: use is controversial. May be indicated in the prehospital setting if administered soon (within 30 minutes) after substantial ingestion. | 【Inhalation】
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols. | 【Skin】
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Vitamin k1 (phytonadione) - is a specific antidote and should be administered to any patient with a prolonged pt. | 【Eyes】
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. Follow treatment recommendations in the dermal exposure section when appropriate. |
| Handling and Storage | Back to Contents | 【Storage】
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. | 【Handling】
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Hazards Identification | Back to Contents | 【Ingestion】
Spontaneous emesis may occur. | 【Inhalation】
Overdosage with anticoagulants may cause acute bleeding. Pre-existing blood clotting disease or liver disease may be aggravated by exposure. | 【Skin】
Ecchymoses and hematomas occur due to reduced clotting capacity. | 【Eyes】
See inhalation | 【Hazards】
This material Fire and runoff from fire control water may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. Container may explode in heat of fire. Enolic form of compound has acidic properties and can form salts with metals. |
| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots. | 【Respirators】
Use NIOSH/MSHA approved respirator appropriate for exposure of concern. | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【Fire Fighting】
(Non-Specific -- Coumarin Derivative Pesticide, Solid, n.o.s.) Stay upwind; keep out of low areas. Wear positive pressure breathing apparatus and special protective clothing. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material.(Non-Specific -- Coumarin Derivative Pesticide, Solid, n.o.s.) Small fires: dry chemical, carbon dioxide, water spray or foam. Large fires: water spray, fog or foam. | 【Fire Potential】
This material may burn but does not ignite readily. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
(Non-Specific -- Coumarin Derivative Pesticide, Solid, n.o.s.) Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Remove and isolate contaminated clothing at the site. Do not touch spilled material. Use water spray to reduce vapors. With clean shovel place material into clean, dry container and cover. Dike far ahead of large spills for later disposal. |
