First-Aid Measures
Safety Data Sheets emphasize immediate medical attention after exposure to CLN 355, detailing specific procedures for inhalation, skin, eye, and ingestion incidents.
Inhalation Exposure
Inhalation of CLN 355 may cause respiratory irritation. Safety Data Sheets recommend removing the affected individual to fresh air immediately. If breathing is difficult, administer oxygen, and seek prompt medical attention. Maintain airway patency and ensure the victim remains calm and comfortable during the process. Monitor for any delayed respiratory distress or adverse reactions, providing continuous support until professional medical help arrives. Prevent further exposure if safe to do so.
Skin Contact Exposure
Skin contact with CLN 355 may lead to irritation. Safety Data Sheets advise immediate washing of the exposed area with copious amounts of soap and water for at least fifteen minutes. Remove contaminated clothing and shoes promptly. If irritation persists, seek medical attention. Thoroughly clean and launder any clothing before reuse to prevent further exposure. Avoid rubbing the affected area, as this could exacerbate irritation and potentially spread the chemical.
Eye Contact Exposure
Eye contact with CLN 355 requires immediate action, as it can cause significant irritation. Safety Data Sheets recommend flushing the eyes with plenty of water for a minimum of fifteen minutes, occasionally lifting the upper and lower eyelids. Seek prompt medical attention, even if initial symptoms appear mild. Do not attempt to use contact lenses during the flushing process, and ensure complete removal before seeking professional care.
Ingestion Exposure
If CLN 355 is ingested, immediate medical attention is critical. Safety Data Sheets advise against inducing vomiting unless specifically directed by medical personnel. Rinse the mouth thoroughly with water and provide the affected individual with fluids to dilute the substance. Never give anything by mouth to an unconscious person. Promptly transport the individual to a medical facility, bringing the SDS for reference.

Fire-Fighting Measures
For CLN 355 fires, utilize appropriate extinguishing media, considering surrounding materials; the SDS details specific hazards arising during combustion events.
Suitable Extinguishing Media
When addressing fires involving CLN 355, the selection of appropriate extinguishing media is paramount for effective fire suppression and minimizing potential hazards.
