• remove protective clothing in the event of visible or suspectedcontamination. Laboratory coats should be able to absorb even largespills and if removed promptly may not contaminate the skin. In somecases, disposable synthetic materials are used for protective clothingwhere maximum impermeability is desired.4.3 Foot protectionOpen-toed shoes, sandals, or other shoes that do not fully enclose the footpose a significant potential for foot injuries in the laboratory. Small pieces ofglass from broken pipettes or test tubes can be trapped easily between thefoot and open shoe causing serious lacerations. A full shoe can protect thefoot from spilled chemicals for enough time to get to a sink or safetyshower. An open shoe affords no protection. Special rubber boots or plasticshoes may be needed where large quantities of solvents might penetratenormal foot gear (e.g. during spill clean-up operations). However, wherespecific laboratory safety rules call for the use of safety shoes, these mustbe worn in accordance with those safety rules.4.4 Hand protectionIn the laboratory, gloves are used for protecting hands from radiation,chemical products, hazardous material and physical hazards such asabrasion, tearing, puncture and exposure to temperature extremes.Latex gloves and skin reactions: Natural latex is derived from the sap ofthe rubber tree and contains rubber polymers, carbohydrates, lipids,phospholipids and proteins. During the manufacturing process additionalchemical agents are added to impart elasticity, flexibility and durability tothe latex. Because of these properties, and because of their high tactilestrength and low cost, latex gloves are used for many laboratoryprocedures. Unfortunately, for some people, wearing latex gloves cancause skin reactions of either an irritant or allergic nature, and can becaused by:• chronic irritation from sweating of hands inside gloves or from glovesrubbing against the skin;• sensitisation to the chemical additives used in the manufacturingprocess;40
• reaction to naturally-occurring latex proteins.Frequent hand-washing, as well as residues from scrubs, soaps, cleaningagents and disinfectants may further irritate the skin. Using one of thefollowing alternatives may reduce the risk of skin problems associated withthe use of latex rubber gloves:• non-latex gloves;• “hypo-allergenic”, non-powdered or low-protein latex gloves;• polyethylene, PVC or cloth liners under latex gloves;• non-latex gloves under latex gloves.Occurrences of skin problems (e.g., rash, itching, peeling, red, blisteringskin or dry flaking skin with cracks and sores) that seem to be associatedwith the wearing of latex gloves should be reported to a physician whensymptoms first appear.Glove selection guidelines: Base selection of glove material on:• identification of the work procedures requiring hand protection;• flexibility and touch sensitivity required: a need for high tactilesensitivity, for example, would restrict glove thickness, and someprotocols may require the use of gloves with non-slip or texturedsurfaces;• type and length of contact (e.g. occasional or splash vs. prolonged orimmersion contact);• whether disposable or reusable gloves are more appropriate.41
