First Aid Measures

Ingestion
Ipecac induced vomiting is not recommended because of the potential for cns depression and seizures. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Oxygen - administer oxygen to all cyanotic or symptomatic patients. Methemoglobinemia: administer 1 to 2 mg/kg of 1% methylene blue slowly iv in symptomatic patients. Additional doses may be required. Shock and cardiac arrest - treat routinely. Adjunctive therapy - exchange transfusions and hyperbaric oxygen may be useful in severe cases.
Inhalation
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
Skin
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.
Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.

Handling and Storage

Storage
Technical product presents good stability when stored in glass, polyolefines, metallic containers with polyolefine lining, at room temperature. It is not advisable to heat the product during long periods above melting point. Technical product of propanil
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

Inhalation
Dyspnea and tachypnea may occur.
Skin
Central cyanosis unresponsive to oxygen therapy is classic.
Ingestion
Nausea and vomiting may occur.

Exposure Controls/Personal Protection

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.
Exposure Effects
CNS effects include headache, dizziness, altered mental status, confusion (lethargy progressing coma), seizures, syncope; occur secondary to CNS hypoxia, usually with levels > 20%.
Poison Class
4

Fire Fighting Measures

Fire Fighting
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 agent most appropriate to extinguish fire.

Accidental Release Measures

Small spills/leaks
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.

Stability and Reactivity

Stability
No data.
Incompatibilities
Strong oxidizing agents.
Decomposition
When heated to decomposition it emits very toxic fumes of hydrogen chloride and nitrogen oxides.
