This is a quality standard set to control the pinhole defects in gloves and is based on the findings of random sampling procedures for any particular batch/lot being produced.
All gloves are tested to determine the Acceptable Quality Level. This involves the sample testing of each batch of gloves to determine the number of non-conformities per 100 units.
A certain quantity from the batch of manufactured products is removed for random testing in accordance with accurately defined procedure. These random samples are then tested in accordance with legally stipulated standards and specifications. From the results, an assessment as to the quality of the entire batch can be made. The higher the requirements on a product, the more stringent the prescribed guidelines are. The AQL is therefore a statistical procedure for determining quality.
International AQL standard for the medical grade gloves is set at a minimum AQL 1.5. This is a probability figure, which simply means that for every batch of gloves manufactured, there is a probability that 1.5% could have pinhole defects. The international standard stipulates that the probability of pinhole defects should not exceed 1.5% for any batch of gloves manufactured.
With High demands of healthcare professionals, many are becoming familiar with clinical governance and other initiatives to improve clinical practice. Good infection control is central to nursing practice. To achieve high standard of clinical practice, and how to reduce the risk of cross-infection,
The selection of the glove begins with an evaluation of the job application. Factors in this selection include :
The key factor for choosing what material the glove is made of is the type of chemical to be handled. The more common materials are :
Highly flexible and conforming produced by rubber plants.
A copolymer available in a wide rang of acrylonitrile content; higher acrylonitrile content equates to greater chemical resistance and increase stiffness.
The greater the thickness of the material selected, the greater protection to chemical exposure is offered. However, with the increased thickness, loss of dexterity, grip and handling safety can be expected.
Gloves that are too small will increase hand fatigue. Gloves that are too large are uncomfortable, hard to work with and can pose a danger if working around moving machinery.
The main function of wearing gloves is to protect the wearer against contamination of infectious materials particularly viruses, bacteria, infected blood and body fluids. Thus, the single most important criterion in glove selection is barrier protection, as defined by all users, including physicians, dentists, medical and non-medical workers and researchers. The next most important criterion is strength, fit and comfort, that is , the ability for the glove to stretch, remain soft, and conform to the hand. Other important requirements include tactile sensitivity, the ability to grip thing well, and the ease of donning. It is widely acknowledged that NR latex gloves are unsurpassed in their range of properties. Hence, selection of glove for safe use should be one with the following properties:
Always inspect your gloves before using them. Principal concern are cuts, tears and punctures. Discoloration or stiffness may indicate compromise due to chemical.
One method to detect pinholes or other defects is to conduct a leak test. One can first stretch the beaded portion of the glove and inspect for tear and holes at the cuff area. Gloves that show no hole(s) shall be filled with air by swinging the piece of glove toward the other hand so that the cuff opening is closed quickly by the grapping hand. Inspect the lightly air inflated glove for leak(s). Dispose of the glove if it leaks.
Pin holes may develop when the gloves are in use. Such phenomena is prominent among gloves made of synthetic materials. Prolonged usage with the same pair of glove is therefore not recommended. there is a need to change gloves at regular intervals to prevent accumulation of fluids in the gloves. For challenging surgical procedures which could sometimes result in holes and cuts, the use of double gloving is recommended to provide maximum protection. The contact with oil-based antiseptics, phenols and their derivatives, petroleum-based grease, kerosene and other related organic compounds, should be avoided.
Hands should first be washed and dried before donning the gloves. It is a good practice to do so to minimize cross contamination and to avoid discoloration of gloves when they are in use.
An open box of glove should not be exposed to direct sunlight, UV lights, moist environment and excessive heat to minimize deterioration in its physical properties. It is recommended that opened boxes of gloves are kept away from light and free moving air by placing them an enclosed container that should be stored in a cool dry place. Storage for an unnecessarily long period is not recommended. As soon as signs of deterioration appear (e.g. tackiness, brittleness, acrid odour), the gloves should not be used.
