物理的状態[外観]: 刺激臭のある無色の圧縮液化ガス,空気より軽い.
化学的危険性:
許容濃度TLV:25 ppm(TWA);35 ppm (STEL) (ACGIH 1998)
容器を開放すると、この気体は空気中できわめて急速に有害濃度に達する。
短期暴露影響:
環境への影響:水生生物に対して毒性が非常に強い。
[火災] 引火性。
[爆発] この気体と空気の混合気体は爆発性である。
[貯蔵]
耐火設備(条件)。酸化剤、酸、ハロゲンから離しておく。涼しい場所。換気のよい場所に保管。
物理的状態[外観]: 刺激臭のある、揮発性の高い無色のアンモニア水溶液。
化学的危険性:
許容濃度TLV(アンモニア):25 ppm;17 mg/m3 (TWA);35 ppm;24 mg/m3 (STEL) (ACGIH 1996)
暴露の経路: 蒸気もしくはエーロゾルの吸入、あるいは経口摂取により体内に吸収される。
吸入の危険性: この物質が20℃で気化すると、空気が汚染されてきわめて急速に有害濃度に達することがある。
短期暴露の影響:
環境への影響: この物質は水生生物に対して毒性が非常に強い。

6. Accidental Release Measures
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill. Wear appropriate personal protective equipment as specified in Section 8. Contain and recover liquid when possible. Do not flush caustic residues to the sewer. Residues from spills can be diluted with water, neutralized with dilute acid such as acetic, hydrochloric or sulfuric. Absorb neutralized caustic residue on clay, vermiculite or other inert substance and package in a suitable container for disposal. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the US Coast Guard National Response Center is (800) 424-8802.
