In evaluating the El Ghawabi et al. (1975) study, a National Research Council (NRC) subcommittee concluded that a 1-h exposure at 8 ppm would cause no more than mild headache in healthy adults (NRC 2000).
份paper too long didnt read
5Hydrogen Cyanide1: Acute Exposure Guideline Levels

今日係空曠兼射得少先8.6
之前濃度係難以想像
係好撚嚴重

幫手補圖
留意返
佢detect其他gas既款
個藍色既位會係其他顏色, e.g. 青/黃/橙...

佢過期tg，即係受潮，所以有機會CS會變咗2-chlorobenzaldehyde同malononitrile.而malononitrile係有兩粒山埃molecules, 溶點32度，沸點220度，即係話相對CS(正常催淚彈)需要少啲能量就可以decompose malononitrile.咁就有可能低啲溫度已經放山埃

10.1.3Fire Hazard
When heated to decomposition, malononitrile emits highly toxic fumes (cyanide). May polymerize violently on prolonged heating. Avoid heat. Hazardous polymerization may occur, at prolonged heating at 266F or contact with strong bases at lower temperatures. (EPA, 1998)
https://onlinelibrary.wiley.com/doi/10.1002/047084289X.rm015
Handling, Storage, and Precautions: caution: highly toxic irritant and should be stored in a well‐ventilated fume hood. Over time, colorless malononitrile becomes dark and eliminates hydrogen cyanide. Inhalation should be avoided. Persons who suffer from a poor sense of smell, heart condition, or blood circulation problems should not be exposed to malononitrile. Above 100 °C, malononitrile may decompose spontaneously.

唔記得打，斷出來個malononitrile，過100度就會decompose放山埃氣
放耐咗本身都會放山埃
