This guide describes the most common types of protective work gloves and the types of hazards they guard against.
1. Disposable Gloves. Usually made of light-weight plastic. They can help guard against mild irritants.
2. Fabric Gloves. Made of cotton or fabric blend. They are generally used to help improve your grip when handling slippery objects. They also help insulate your hands from mild heat or cold.
3. Leather Gloves. Used to guard against injuries from sparks or scraping against rough surfaces. You should use them in combination with an insulated liner if you are working with electricity.
3. Chemical Resistance Gloves. May be made of rubber, neoprene, polyvinyl alcohol or vinyl, etc. They protect your hands from corrosives, oils, and solvents.
4. Metal Mesh Gloves. Used to protect your hands from accidental cuts and scratches. They are used most commonly by persons working with cutting tools or other sharp instruments.
5. Aluminized Gloves. Made of aluminized fabric. They are designed to insulate your hands from intense heat. These gloves are most commonly used by persons working with molten materials.
The following tables are guides to the different types of glove materials and the chemicals they will protect you against. Note1: When you are selecting chemical resistance gloves, be sure to consult the manufacturer's recommendations, especially if your gloved hand will be immersed in the chemical. Note2: Latex gloves are known to cause allergic reactions to individuals donning the gloves. Please substitute another appropriate non-latex glove from the attached chart and replace it.
Glove Chart
Type | Advantages | Disadvantages | Use Against |
Natural Rubber | Low cost, good physical properties, dexterity | Poor against oils, greases, organics. Frequently imported; may be poor quality | Bases, alcohols, dilute water solutions; fair against aldehydes, ketones |
Natural rubber blends | Low cost, dexterity, better chemical resistance than natural rubber against some chemicals | Physical properties frequently inferior to natural rubber | Bases, alcohols, dilute water solutions; fair against aldehydes, ketones |
Polyvinyl
chloride (PVC) |
Low cost, very good physical properties, medium cost, medium chemical resistance | Plasticizers can be stripped; frequently imported may be poor quality | Stong acids and bases, salts, other water solutions, alcohols |
Neoprene | Medium cost, medium chemical resistance, medium physical properties | Oxidizing acids, anilines, phenol, glycol ethers | |
Nitrile | Low cost, excellent physical properties, dexterity | Poor against benzene, methylene chloride, trichloroethylene, many ketones | Oils, greases, aliphatic chemicals, xylene, perchloroethylene, trichloroethane; fair against toluene |
Butyl | Speciality glove, polar organics | Expensive, poor against hydrocarbons, chlorinated solvents | Glycol ethers, ketones, esters |
Polyvinyl alcohol (PVA) | Specialty glove, resists a very broad range of organics, good physical properties | Very expensive, water sensitive, poor against light alcohols | Aliphatics, aromatics, chlorinated solvents, ketones (except acetone), esters, ethers |
Fluoroelastomer (Viton)* | Specialty glove, organic solvents | Extremely expensive, poor physical properties, poor against some ketones, esters, amines | Aromatics, chlorinated solvents, also aliphatics and alcohols |
Norfoil (Silver Shield) | Excellent chemical resistance | Poor fit, easily punctures, poor grip, stiff | Use for Hazmat work |
