Hand protection Skin contact a potential source of
exposure to toxic materials Four main hazard categories: chemicals,
abrasions, cutting, and heat Gloves available that can protect workers
from any of these individual hazards or any combination thereof

Introduction Gloves should be replaced periodically,
depending on frequency of use and permeability to the substance
Gloves overtly contaminated should be rinsed and then carefully removed after use
Gloves should also be worn whenever it is necessary to handle rough or sharp-edged objects, and very hot or very cold materials
leather, welder’s gloves, aluminum-backed gloves, and other types of insulated glove materials

Common types of gloves Disposable Gloves
Usually made of light-weight plastic against mild irritants
Fabric Gloves Made of cotton or fabric generally used to improve grip when handling
slippery objects insulate hands from mild heat or cold

Leather Gloves Against injuries from sparks or scraping against
rough surfaces used in combination with an insulated liner
when working with electricity Metal Mesh Gloves
To protect hands form accidental cuts and scratches
Used most commonly by persons working with cutting tools or other sharp instruments
