  1. Hand protection By A.H.Mherparvar

  2. 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

  3. 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

  4. 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

  5. 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

  6. Aluminized Gloves • made of aluminized fabric • designed to insulate hands from intense heat • most commonly used by persons working molten materials • Chemical Resistance Gloves • Protect hands from corrosives, oils, and solvents • Rubber • Neoprene • polyvinyl alcohol • Vinyl

  7. Chemical resistance gloves Natural rubber • Advantages: • Low cost, good physical properties, dexterity • Disadvantages: • Poor vs. oils, greases, organics • Uses: • Bases, alcohols, dilute water solutions • fair vs. aldehydes, ketones

  8. PVC • Advantages: • Low cost, very good physical properties, medium chemical resistance • Uses: • Strong acids and bases, salts, other water solutions, alcohols

  9. Neoprene: • Advantages: • Medium cost, medium chemical resistance, medium physical properties • Uses: • acids, anilines, phenol, glycol ethers

  10. Nitrile: • Advantages: • Low cost, excellent physical properties, dexterity • Disadvantages: • Poor vs. benzene, methylene chloride, trichloroethylene, many ketones • Uses: • Oils, greases, aliphatic chemicals, xylene, perchloroethylene, trichloroethane • fair vs. toluene

  11. Butyl • Advantages: • Specialty glove, polar organics • Disadvantages: • Expensive, poor vs. hydrocarbons, chlorinated solvents • Uses: • Glycol ethers, ketones, esters

  12. PVA: • Advantages: • Specialty glove, resists a very broad range of organics, good physical • Disadvantages: • Very expensive, poor vs. light alcohols • Uses: • Aliphatics, aromatics, chlorinated solvents, ketones (except acetone), esters, ethers
