FIRST AID

Inhalation:
Move to fresh air if vapors or mists are inhaled.
Seek medical attention if coughing or respiratory irritation persists.
Avoid breathing mists during spraying or heated processing.

Skin Contact:
Wash with soap and water after contact.
Remove contaminated clothing and wash before reuse.
Seek medical advice if irritation develops or persists.

Eye Contact:
Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do.
Continue rinsing and seek medical attention if irritation persists.

Ingestion:
Rinse mouth with water.
Do not induce vomiting unless directed by medical personnel.
Seek medical attention if large amounts are swallowed or discomfort occurs.

Note to Physicians:
Treat symptomatically.
No specific antidote is required.
Provide supportive care based on exposure route and symptoms.

HANDLING AND STORAGE

Handling:
Use appropriate PPE, including gloves and safety glasses.
Avoid generating aerosols or mists, especially during spraying.
Wash hands after handling and before eating, drinking, or smoking.

Ventilation:
Use local exhaust or general ventilation in areas where mists may form.
Ensure adequate ventilation if the product is heated during processing.
Avoid prolonged exposure to vapors from hot mixtures.

Storage:
Store in a cool, dry place in tightly closed containers.
Protect from moisture pickup, as polyethers can be hygroscopic.
Keep away from strong oxidizers and sources of contamination.

Spill and Leak Procedures:
Contain the spill and absorb with inert material such as sand or universal absorbent.
Clean residue with water and detergent while preventing slips on slick surfaces.
Dispose of waste according to local regulations and facility procedures.

Handling Precautions:
Use clean, dedicated equipment to prevent cross-contamination in regulated applications.
Maintain good housekeeping because spilled material can create a slip hazard.
Rotate stock using FIFO practices to maintain consistent performance.
