窒息性物質は危険物 の一種であり、漏洩 すれば一時的な呼吸困難を引き起こす可能性があります。

In order to transport gasses in as big an amount as possible, many are transported pressurized. In case of a leak, as the gas is equalized with atmospheric pressure, it will take much greater volume than the tank it was transported in. This can cause dislocation of air around the train, potentially leading to suffocation of people and animals in its vicinity.

一方、窒息性ガスには、危険な面だけでなく、良い面もあります。漏洩事故の際に、酸素を遮断するため、消火に寄与します。
