SECTION 6 — ACCIDENTAL RELEASE MEASURES

Remove all ignition sources and ventilate area. Contain the spill with sand or other inert absorbent material, neutralize with sodium bicarbonate or calcium hydroxide, and deposit in a sealed bag or container. See Sections 8 and 13 for further information.

SECTION 7 — HANDLING AND STORAGE

Flinn Suggested Chemical Storage Pattern: Organic #1. Store with acids, anhydrides and peracids.
Keep cool (P235). Keep container tightly closed (P233). Store in a dedicated acid cabinet and away from any source of water; if an acid cabinet is not available, store in a Flinn Saf-Cube™. Avoid prolonged storage (see Section 10). Use only in a hood or well-ventilated area (P271).

SECTION 8 — EXPOSURE CONTROLS, PERSONAL PROTECTION

Wear protective gloves, protective clothing, and eye protection (P280). Wash hands thoroughly after handling (P264). Use only in a hood or well-ventilated area (P271).
Exposure guidelines: PEL/TLV 5 ppm (OSHA/ACGIH); Ceiling 10 ppm (ACGIH)

SECTION 9 — PHYSICAL AND CHEMICAL PROPERTIES

Clear, colorless, fuming liquid. Penetrating odor.
Soluble: Water, alcohol, and ether

Boiling point: 101 °C
Melting point: 8.3 °C
Refractive index: 1.3714
Specific gravity: 1.22

SECTION 10 — STABILITY AND REACTIVITY

Avoid contact with strong oxidizers, strong bases, and finely powdered metals.
Shelf life: Poor. Avoid extended storage. Upon aging, decomposes to carbon monoxide and water thus creating potential explosive danger in a tightly sealed bottle. Explosions have occurred.
