Abstract from DBPedia
    A hazard is a potential source of harm. Substances, events, or circumstances can constitute hazards when their nature would allow them, even just theoretically, to cause damage to health, life, property, or any other interest of value. The probability of that harm being realized in a specific incident, combined with the magnitude of potential harm, make up its risk, a term often used synonymously in colloquial speech. Hazards can be classified in several ways. They can be classified as natural, anthropogenic, technological, or any combination, such as in the case of the natural phenomenon of wildfire becoming more common due to human-made climate change or more harmful due to changes in building practices. A common theme across many forms of hazards in the presence of stored energy that, when released, can cause damage. The stored energy can occur in many forms: chemical, mechanical, thermal, radioactive, electrical, etc. Situations can also be hazardous, for example, confined or limited egress spaces, oxygen-depleted atmospheres, awkward positions, repetitive motions, low-hanging or protruding objects, etc. They may also be classified as health or safety hazards and by the populations that may be affected and the severity of the associated risk. In most cases, a hazard may affect a range of targets and have little or no effect on others. Identification of hazards assumes that the potential targets are defined, and is the first step in performing a risk assessment.

    危険有害性(きけんゆうがいせい)は、爆発物や引火性などの危険性と、発がん性、急性毒性、水生環境有害性などのの総称である。同じ意味でハザード、危害、とよばれることもある。単に危険性と呼ばれることもある。 2008年に国際的に導入が予定されている化学品の分類および表示に関する世界調和システム(GHS)の日本語訳で、英語の"hazard"の訳語として公的に使われている。 中国語では単に(危险)である。 国連危険物輸送勧告で危険性としている次のようなものは危険有害性を持つと言える: * 火薬類 * 引火性/可燃ガス * 引火性エアゾール * 酸化性ガス * 高圧ガス * 引火性液体 * 可燃性固体 * 自己反応性化学品 * 自然発火性液体 * 自然発火性固体 * 自己発熱性化学品 * 水反応可燃性/禁水性化学品 * 酸化性液体 * 有機化酸化物 * 金属腐食性物質 * 放射性物質
