Safety Engineering

Japanese: 安全性工学 - あんぜんせいこうがく
Safety Engineering

...The later in the development process safety issues are discovered, the more difficult it becomes to address them, and the more time and money it takes, so safety must be built into the product primarily at the design stage. A technique called safety engineering is used to ensure safety, and the core of this is safety analysis, which will be discussed next as development progresses.
[Initial hazard analysis]
In the analysis carried out at the initial design stage, the focus is on energy sources such as power, electricity, and fuel based on past experience with similar systems, and hazards that could cause fires or explosions and areas requiring safety precautions are identified, and countermeasures are decided.

*Some of the terminology that refers to "safety engineering" is listed below.

…安全性に関する問題は開発の後期になって発見されるほど,その対策には困難さが増すうえ,時間と費用がより多くかかるので,主として設計段階で製品に安全性を組み込む必要がある。安全性確保のため安全性工学と呼ばれる技術が用いられるが,その骨子となる安全性解析について開発の進展に応じ次にのべる。
【初期ハザード解析】
 初期設計の段階に行う解析で,過去の類似システムの経験から動力,電気,燃料などのエネルギー源に着目し火災,爆発などの原因となるハザードと安全上注意すべき領域を見いだし,対策を決める。…
