Safety & Health
- Health & Safety Information
- Under current U.S. OSHA's Hazardous Communication program THF is classified as a flammable liquid, can cause eye and respiratory irritation. Keep the material away from heat sources, hot surfaces, open flames, and sparks. Use only in a well‐ventilated area.
- Observe good industrial hygiene practices and use appropriate Personal Protective Equipment.
Storage & Handling
- Storage & Handling
THF should be stored only in tightly closed, properly vented containers away from heat, sparks, open flame or strong oxidizing agents. Use only nonsparking tools. Containers should be grounded before beginning transfer. Electrical equipment should conform to national electric code. Handle empty containers carefully. Flammable combustible residue remains after emptying.
General industry practice is to store THF in carbon steel vessels. Storage in properly lined steel or stainless steel to avoid slight discoloration from mild steel is recommended. Avoid contact with air when storing for long periods of time. This product may absorb water if exposed to air.
Provided proper storage and handling precautions are taken, THF manufactured and delivered by Monument Chemical is stable for at least 12 months from the date of manufacture. THF that is subsequently repackaged, handled and/or delivered by third parties may have a different shelf life and may require third party shelf life studies. Product past the retest date should be evaluated to confirm that all specifications are within their limits before use.
