Exposure limits

ACGIH: STEL 1000 ppm
OSHA: TWA 1000 ppm(1900 mg/m3)
NIOSH: IDLH 3300 ppm; TWA 1000 ppm(1900 mg/m3)

Stability:

Stable, but highly flammable. Reacts violently with water. Contact with damp air may lead to heating of the solid, which could in turn ignite it, or materials with which it is in contact. Incompatible with air, water, moisture, acids, acid chlorides, acid anhydrides, oxidizing agents, reducing agents.
