Selection of Hand Protection
It's important employers work closely with their PPE supplier to select appropriate hand protection based on an evaluation of the performance characteristics of the hand protection.
- specific task(s) being performed
- environmental conditions present
- duration of hand protection use while performing the task
- the actual hazards
- potential hazards
- degree of dexterity required
- duration of the task
- frequency of the task
- degree of exposure of the hazard
- physical stresses that will be applied.
Gloves should be replaced periodically. How often depends on frequency of use and permeability to the substance(s) handled. Gloves overtly contaminated should be rinsed and then carefully removed after use. With this in mind, there are two important characteristics of gloves to consider.
Permeation rate: The permeation rate measures the length of time it takes a given material (glove) to become saturated by the chemical through absorption.
Breakthrough or Penetration rate: The penetration rate measures the speed with which a given chemical breaks through the layer(s) of the glove to contact the skin.
Gloves should also be worn whenever it is necessary to handle rough or sharp-edged objects, and very hot or very cold materials. The type of glove material to be used in these situations includes leather, welder's gloves, aluminum-backed gloves, and other types of insulated glove materials.
