Hazards and Protection.
Storage
Keep containers of 2,4,5-t and derivatives tightly closed at ambient temperature in a well-ventilated area away from food and feed products, heat, and water. Do not store near other agrochemicals or seeds.
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.
Protection

Stability
No data.

Fire.
