危険有害性情報
Regulatory InformationThe New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)
DOT LabelCorrosive
Fire Hazards
Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]:
· Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Health Hazards
Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]:
· TOXIC and/or CORROSIVE; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.

Reactive GroupAcids, Strong Non-oxidizing
Reactivity AlertsWater-Reactive
Reactivity Profile
PHOSPHORUS TRIOXIDE reacts exothermically with bases. Melted phosphorus trioxide readily ignites in air. Instantly ignites with a flame of almost blinding brilliance when thrown into oxygen at 50-60 °C [J. Am. Chem. Soc. 125:347. 1924]. Incompatible with ammonia, disulfur dichloride, halogens, oxygen, phosphorus pentachloride, sulfur, sulfuric acid, water [Bretherick, 5th ed., 1995, p. 1778].
DOT Hazard Classification
Phosphorus trioxide
UN2578
Class 8 Corrosive material (49 eCFR § 173.136)
PG III: the degree of danger presented by the material is minor
Air and Water ReactionsFumes in air. Reacts slowly with cold water to give phosphorous acid. Reacts vigorously with hot water to generate red phosphorus, phosphine (highly toxic and flammable) and phosphoric acid [Merck 11th ed. 1989].
