Chemical Identification/RIDS Larqe spills: dike far ahead of spill for later disposal. (EPA, 1998) Health Hazard Can cause death due to severe injury to the lungs. The lowest lethal oral dose reported in humans is 43 mg/kg. (EPA, 1998) Properties Melting Point: Decomposes 572° F (EPA, 1998) Vapor Pressure: Approximately 0 (EPA, 1998) Boiling Point: Decomposes (NIOSH, 2003) Molecular Weight: 257.18 (EPA, 1998) IDLH: 1 mg/m3 (NIOSH, 2003) TEEL1: 0.3 mg/m3 (TEEL, 2003) TEEL2: 1 mg/m3 (TEEL, 2003) TEEL3: 1 mg/m3 (TEEL, 2003) Water Solubility: greater than or equal to 100 mg/mL at 66° F (NTP, 1992) Specific Gravity: 1.24-1.26 at 68° F (NTP, 1992) First Aid Warning: Effects occur in two stages, immediate and delayed. Caution is advised. Exposure to paraquat may be fatal; there is no effective antidote. Signs and Symptoms of Acute Paraquat Exposure: Signs and symptoms of acute exposure to paraquat may be severe and include nausea, vomiting, diarrhea, and abdominal pain. A burning sensation of the mouth and esophagus with possible ulceration may occur following ingestion. Eye exposure may result in corneal opacification (cloudiness). Dermatitis and nail atrophy may occur following dermal contact. Delayed effects include transient reversible liver injury, acute renal failure, and progressive pulmonary fibrosis with associated dyspnea (shortness of breath) and pulmonary edema. Emergency Life -Support Procedures: Acute exposure to paraquat may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air -purifying or supplied -air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination. Inhalation Exposure: 1. Move victims to fresh air. Emergency personnel should avoid self -exposure to paraquat. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 3. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures. 4. RUSH to a health care facility. Dermal/Eye Exposure: 1. Remove victims from exposure. Emergency personnel should avoid self- exposure to paraquat. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 3. Remove contaminated clothing as soon as possible. 4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes. 5. Wash exposed skin areas three times with soap and water. 6. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures. 7. RUSH to a health care facility. Ingestion Exposure: 1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 2. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures. 3. Vomiting may be induced with syrup of Ipecac. If elapsed time since ingestion of paraquat is unknown or suspected to be greater than 30 minutes, do not induce vomiting and proceed to Step 4.Ipecac should not be administered to children under 6 months of age.Warning: Syrup of Ipecac should be administered only if victims are alert, have an active gag -reflex, and show no signs of impending seizure or coma. If ANY uncertainty exists, proceed to Step 4.The following dosages of Ipecac are recommended: children up to 1 year old, 10 mL (1/3 oz); children 1 to 12 years old, 15 mL (1/2 oz); adults, 30 mL (1 oz). Ambulate (walk) the victims and give large quantities of water. If vomiting has not occurred after 15 minutes, Ipecac may be readministered. Continue to ambulate and give water to the victims. If vomiting has not occurred within 15 minutes after second administration of Ipecac, administer activated charcoal. 4. Activated charcoal may be administered if victims are conscious and alert. Use 15 to 30 g (1/2 to 1 oz) for children, 50 to 100 g (1-3/4 to 3-1/2 oz) for adults, with 125 to 250 mL (1/2 to 1 cup) of water. 5. Promote excretion by administering a saline cathartic or sorbitol to conscious and alert victims. Children require 15 to 30 g (1/2 to 1 oz) 6/12/2007 Printed from CAMEO Page 2
