Tibbiyot xodimlari bemorlarga burun va og‘izlaridan mikroblarni yuqishini oldini olish hamda o‘zlarini infeksiyadan himoya qilish uchun yuz niqoblarini kiyishadi. Ular kiygan kiyimlar va xalatlar xam tibbiyot xodimlari va bemorlarni, shuningdek, operatsiya paytida ishlatiladigan pardalarni kasallikning tasodifiy yuqishidan himoya qiladi.
So‘nggi bir necha hafta ichida himoya kiyimlari mavzusi juda keng tarqalgan bo‘lib, ushbu mahsulotlar COVID-19 virusiga javoban kasalxonalar va sog‘liqni saqlash muassasalari tashqarisida keng qo‘llanilmoqda. Yuz maskalari, xalatlar va boshqa himoya kiyim-kechak buyumlari katta talabga ega, chunki odamlar yangi koronavirus tarqalishidan yoki yuqishidan saqlanishga intilmoqda.
Ushbu mahsulotlarning barchasi ASTM International tashkilotining shaxsiy himoya kiyim va jihozlari bo‘yicha qo‘mitasi (F23) va uning biologik qo‘mitasi (F23.40) nazorati ostida amalga oshiriladi. Biologik quyi qo‘mitasi tibbiyot xodimlarini va sog‘liqni saqlash muhitini infeksiyani keltirib chiqarishi mumkin bo‘lgan biologik xavflardan himoya qilishga mo‘ljallangan standartlarni ishlab chiqadi va qo‘llab-quvvatlaydi..
Sara Smit, biologik quyi qo‘mitaning raisi, yaqinda himoya shaxsiy uskunalar uchun eng muhim standartlarni (SIZ) aniqladi (quyida xavola etiladi). Ushbu standartlar ASTM International tashkiloti tomonidan ishlab chiqaruvchilarga, sinov laboratoriyalarga, sog‘liqni saqlash sohasi mutaxassislariga va keng jamoatchilikka mavjud koronavirus kasalligi (COVID-19) xavfsiz o‘tishini ta’minlash maqsadida bepul taqdim etaladi.
Standart turlari:
1. Specification for performance of materials used in medical face masks (F2100);
2. Test Method for Evaluating the Bacterial Filtration Efficiency (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus (F2101);
3. Test method for determining the initial efficiency of materials used in medical face masks to penetration by particulates using latex spheres (F2299/F2299M);
4. Test method for resistance of medical face masks to penetration by synthetic blood (horizontal projection of fixed volume at a known velocity) (F1862/F1862M);
5. Test method for resistance of materials used in protective clothing to penetration by blood-borne pathogens using Phi-X174 bacteriophage penetration as a test system (F1671/F1671M)
