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 GLOVES

Rather than immersing hands in to a container of chemicals consider the use of: Forceps Crucible Tongs Baskets A magnetic flea retriever

Dishwashers are an alternate to washing glassware by hand

PROBLEMS WITH GLOVES

Reduced dexterity Reduced tactile sensation Accumulation of sweat Allergic reactions Time to put on and take off Poor fit or comfort Cost Maintenance and cleaning Inconvenient and interference with the work Workplace 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

DEGRADATION

The 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

PERMEATION

There 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 material

PERMEATION

WEARING, CLEANING AND DISPOSAL

Wash hands before and after using gloves Cover cuts with a non-absorbent dressing Inspect the glove prior to use Replace disposable gloves often Never reuse disposable gloves Reused non-disposable gloves with caution Store gloves away from direct sunlight or

extremes of temperature.
