In lieu of the traditional 1-L water-leak test, a modified water-leak test, standardized to detect a 0. Each glove was closely observed for leaks immediately after the introduction of water and then again after 2 min. Chlorination is the traditional process and requires gloves to be washed prior to packing. Preliminary investigation indicated this was an issue with holes made by a gauge needle. Cleanroom gloves had the highest average failure percentages, followed in descending order by the general duty, low-modulus, and medical grade gloves. The goal was to closely match the gauge pressure with both 1 the palmar ventral stretch during hand extension, and 2 the dorsal stretch during hand flexion or grasping. Nonetheless, there were indications that glove integrity became increasingly compromised with duration of use.
Integrity of Disposable Nitrile Exam Gloves Exposed to Simulated Movement
On average, the glove products that required an additional 0. Three glove products had no leak failures or defects, whereas one glove product was defective. In all cases, the less a glove is washed, the more chemical residue is available for potential contact to the user. Drafting tape was used to capture the bidirectional stretch of an ink mark. The symptoms vary widely and mild episodes may involve skin flushing, itching, or tingling with hives that have blanched or white centers.
Modified water-leak test apparatus: Latex allergy should be suspected in anyone who develops certain symptoms after latex exposure. The cuff region was precluded, because stretching was determined to be greatest in the palm, knuckle, and finger regions. Second, glove failure results were inconsistent between the glove products. Adding curatives, cross-link agents, and accelerators to nitrile and natural latex is essential to making a strong, durable glove.
Glove materials were labelled with pairs of parallel lines, vertically crossing in the centre of the test material. For each glove product, 30 thickness measurements 9 finger, 3 thumb, 9 knuckle, and 9 palm were performed using a digital micrometer with constant force ratchet-stop to ensure precision. Nonetheless, there were indications that glove integrity became increasingly compromised with duration of use. The glove product failed if the percentage of defective gloves was greater than 4. Variation was observed between glove products within each glove type. Appl Occup Environ Hyg.
