WHEN SHOULD GLOVES BE WORN?Protective gloves should be worn when a risk assessment of the task to be performed, has identify hazards that can be minimised by the wearing of gloves. The wearing of gloves is the least desirable alternative when selecting a control measure using the Hierarchy of Controls. Often they are worn if other more preferred measures, do not sufficiently minimise the risks.

ALTERNATIVES TO GLOVESRather than immersing hands in to a container of chemicals consider the use of:ForcepsCrucible TongsBasketsA magnetic flea retrieverDishwashers are an alternate to washing glassware by hand

PROBLEMS WITH GLOVESReduced dexterityReduced tactile sensationAccumulation of sweatAllergic reactionsTime to put on and take offPoor fit or comfortCostMaintenance and cleaningInconvenient and interference with the workWorkplace conditions heat, wet work, repetitive movement

PHYSICAL CHARACTERISTICS OF GLOVES MATERIAL There are three factors that affect the physical characteristics of glove material: degradation permeation breakthrough time

DEGRADATIONThe chemical changes the physical and/or chemical properties of the glove. This is often (but not always) visible to the naked eye. Signs of degradation include swelling, loss of flexibility, tackiness etc

PENETRATION

PERMEATION

PERMEATIONThere are two factors to consider when looking at permeation of a chemical through a glove. Permeation rate - the rate at which a substance permeates the glove material. Breakthrough time - the time elapsed between initial contact of a chemical with the outside surface of the glove material and the time at which the chemical can be detected at the inside surface of the materialPERMEATION

WEARING, CLEANING AND DISPOSALWash hands before and after using glovesCover cuts with a non-absorbent dressingInspect the glove prior to use Replace disposable gloves often Never reuse disposable gloves Reused non-disposable gloves with cautionStore gloves away from direct sunlight or extremes of temperature.
