Darhol hayot yoki sog'liq uchun xavfli - Immediately dangerous to life or health

IDLH sharoitlari uchun shaxsiy himoya vositalari: to'liq talab qilinadigan nafas olish apparati bilan birgalikda to'liq yuz pardasi bilan jihozlangan, havo talabiga javob beradigan havo nafas olish apparati.

Atama hayot yoki sog'liq uchun darhol xavfli (IDLH) AQSh tomonidan belgilanadi Mehnatni muhofaza qilish milliy instituti (NIOSH) havodagi ifloslantiruvchi moddalarga ta'sir qilish, bu "o'limga olib kelishi yoki sog'liqqa zudlik bilan yoki kechiktirilishi yoki doimiy ravishda sog'liqqa salbiy ta'sir ko'rsatishi yoki bunday muhitdan qochishning oldini olishi mumkin". Masalan, tutun yoki boshqa zaharli gazlar etarli darajada yuqori konsentratsiyalarda. U yordamida hisoblab chiqiladi LD50 yoki LC50.^[1] The Mehnatni muhofaza qilish boshqarmasi (OSHA) reglamenti (1910.134 (b)) ushbu atamani "hayotga zudlik bilan tahdid soladigan, sog'likka qaytarib bo'lmaydigan salbiy ta'sirlarni keltirib chiqaradigan yoki shaxsning xavfli atmosferadan qochish qobiliyatini buzadigan atmosfera" deb ta'riflaydi.^[2]

IDLH qiymatlari ko'pincha muayyan vaziyatlarda ishchilar yoki o't o'chiruvchilarga taqdim etiladigan nafas olish moslamalarini tanlashga rahbarlik qilish uchun ishlatiladi.^[1]

NIOSH ta'rifi o'z ichiga olmaydi kislorod etishmovchiligi (19,5 foizdan past) bo'lsa-da, atmosferani ta'minlaydigan nafas olish apparati ham zarur. Masalan, baland balandliklar va shamollatilmagan, cheklangan joylar.

OSHA ta'rifi, shubhasiz, "havoga tushadigan ifloslantiruvchi moddalar" bo'lmagan taqdirda kislorod etishmasligi holatlarini, shuningdek hayot yoki sog'liq uchun boshqa ko'plab kimyoviy, termal yoki pnevmatik xavflarni (masalan, toza geliy, o'ta sovigan yoki o'ta sovigan) o'z ichiga oladigan darajada kengdir. isitiladigan havo, giperbarik yoki gipo-barik yoki suv osti kameralari va boshqalar). Shuningdek, u qochish qobiliyatiga nisbatan "oldini olish" o'rniga "buzish" degan kengroq atamani qo'llaydi. Masalan, ko'r-ko'rona, ammo toksik bo'lmagan tutun, agar u "xavfli", ammo hayot uchun xavfli bo'lmagan atmosferadan (ko'z yoshi chiqaradigan gaz kabi) qochish qobiliyatini buzsa, OSHA ta'rifi bo'yicha IDLH deb hisoblanishi mumkin.

OSHA ta'rifi eng kam huquqiy talab bo'lgan huquqiy standartning bir qismidir. Foydalanuvchilar yoki ish beruvchilar vaqtinchalik og'riq, yo'nalish buzilishi, ko'ngil aynishi yoki toksik bo'lmagan ifloslanish kabi birdan bir zudlik bilan xavfi "qaytariladigan" bo'lsa ham, keraksiz xatarlarga duch kelmaslik uchun tegishli qarorlarni qo'llashlari tavsiya etiladi.

NIOSH respiratorini tanlash mantiqi

IDLH sharoitlari uchun shaxsiy himoya vositalari: to'liq yuzli, bosimga asoslangan o'z-o'zidan ishlaydigan nafas olish apparati

Agar zararli moddalarning konsentratsiyasi IDLH bo'lsa, ishchi eng ishonchli respiratorlardan foydalanishi kerak. Bunday nafas olish apparatlarida sorbent bilan patronlar yoki qutilar ishlatilmasligi kerak, chunki ularning umri ham yomon prognoz qilingan. Bunga qo'shimcha ravishda, nafas olish apparati ilhom paytida niqob ostida ijobiy bosimni ushlab turishi kerak, chunki bu bo'shliqlar orqali filtrlanmagan havoning chiqib ketishini oldini oladi (ba'zan niqob chekkalari va yuz o'rtasida paydo bo'ladi).

NIOSH darsligi^[3] faqat IDLH sharoitida foydalanish uchun tavsiya etiladi bosimni talab qiladigan mustaqil nafas olish apparati to'liq nafas olish moslamasi bilan birgalikda to'liq facepiece bilan jihozlangan to'liq facepiece yoki bosim bilan ta'minlangan havo nafas olish apparati bilan.

IDLH qiymatlari

IDLH qiymatlari bo'yicha quyidagi misollar keltirilgan.^[4]

Afsona:^[5]

Ca: NIOSH ushbu moddani potentsial kasbiy kanserogen deb hisoblaydi. Qayta ko'rib chiqilgan qiymatlar qavs ichida bo'lishi mumkin.
N.D.: Belgilanmagan. Ya'ni, darajasi noma'lum, mavjud emas.
10% LEL: IDLM qiymati portlovchi moddalarning quyi chegarasining 10% darajasida o'rnatildi, ammo toksikologiya tufayli sog'liqqa qaytarib bo'lmaydigan boshqa ta'sirlar yoki qochishning buzilishi faqat yuqori darajada mavjud.
