7. Troubleshooting and Emergency Procedures

This section provides general guidance for common issues and emergency situations related to handling 2,4-Dihydroxybenzoic Acid. Always refer to the product's Safety Data Sheet (SDS) for comprehensive emergency information.

7.1 Spills:

• Small Spills: Absorb with inert material (e.g., sand, vermiculite, diatomaceous earth). Place in a suitable, closed container for disposal. Clean the spill area thoroughly.
• Large Spills: Evacuate personnel from the area. Isolate the hazard area and deny entry to unnecessary and unprotected personnel. Wear appropriate PPE. Contain and collect the spilled material. Contact emergency services if necessary.

7.2 Exposure:

• Inhalation: Move to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek immediate medical attention.
• Skin Contact: Wash off with plenty of soap and water. Remove contaminated clothing and shoes. Seek medical attention if irritation develops or persists.
• Eye Contact: Rinse thoroughly with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Consult a physician.
• Ingestion: Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. Seek immediate medical attention.

7.3 Product Degradation:

If the product shows signs of degradation (e.g., significant discoloration, change in physical state, or unexpected odor), it may no longer meet its specified purity. Do not use for critical applications. Consult TCI America for guidance on disposal or replacement.
