3.4 Hand Protection
Most hazards to the hands and arms in laboratory and animal research environments can be grouped into four general categories: chemical exposure, mechanical hazards (e.g., cuts, abrasions, punctures), biological exposure, and temperature extremes (heat or cold). As part of baseline laboratory PPE expectations, gloves appropriate to the task must be worn when handling hazardous materials or when there is a reasonable potential for exposure to these hazards.
The proper selection and use of hand protection can reduce exposure to both chemical and physical hazards. Gloves must be worn when working with materials that are readily absorbed through the skin and/or particularly hazardous substances (such as select carcinogens, reproductive toxins, and substances with a high degree of acute toxicity).
All glove materials are eventually permeated or degraded by chemicals; however, they can be used safely for limited periods when their performance characteristics (e.g., thickness, permeation rate, and breakthrough time) are understood. EHS can provide assistance in selecting appropriate glove materials for specific applications.
