Hasma, A.B. Othman and M.S. Fauzi Barrier integrity of NR, vinyl and nitrile examination gloves was determined by assessing the amount of virus (FX174) suspension penetrating through the fingers punctured with acupuncture and syringe needles of 0.22 mm to 0.45 mm diameter The water leak test showed a 100%.failure in vinyl and nitrile gloves when punctured with 0.3 mm and 0.4 mm needles, respectively. NR gloves, however, showed markedly less failure even when punctured with needles up to 0.45 mm diameter. Failure in water leak test indicated a virus penetration of >2 µL. Puncture with 26G syringe needle showed > 2500 µL of virus suspension penetrating through vinyl and nitrile gloves compared to < 25 µL with NR gloves. The low leak from punctured NR gloves was observed to be associated with their low modulus and high tear strength resistance compared to those of vinyl and nitrile gloves. Scanning electron micrograph showed apparently closed tear slit in NR gloves compared to the opened tear in vinyl and nitrile gloves. back
