FIRST AID

Inhalation:
Move to fresh air if dust is inhaled.

Remove contact lenses if present and easy to do, then continue rinsing.
Seek medical attention promptly if irritation persists.

Ingestion:
Rinse mouth with water and do not induce vomiting.
Seek medical attention if discomfort occurs or if a significant amount is swallowed.
Never give anything by mouth to an unconscious person.

Note to Physicians:
Treat symptomatically.
Consider allergic sensitization potential.
Provide supportive care as needed.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including chemical-resistant gloves, safety glasses, and protective clothing.
Avoid generating dust and avoid inhalation of powder.
Use closed transfer, local exhaust, and dust collection where possible.

Ventilation:
Use general ventilation for normal handling.
Use local exhaust at points of dust generation during weighing, blending, and charging.
Avoid handling in confined spaces without adequate airflow.

Storage:
Store in tightly closed containers in a cool, dry place.
Protect from moisture, contamination, and excessive heat to maintain consistent performance.

Handling Precautions:
Control exposure because Tris(2,3-Epoxypropyl) Isocyanurate can cause skin sensitization and irritation, and dust is the primary exposure risk.
Optimize formulation balance because high crosslink density can increase hardness but reduce flexibility, and performance depends on resin selection and stoichiometry.
Rotate stock using FIFO practices to maintain consistent quality and predictable curing performance.
