Guidelines on the Use of PPE Against Chemical Hazards


               3.2.5. Body Protection

                       Types

                       The risk that workers may encounter include heat, cold, bad weather, chemical or
                       metal splash, spray from pressure leaks  or spray guns, impact or penetration,
                       contaminated dust, and excessive wear or entanglement of own clothing.

                       The   types   of    body   protection   include
                       conventional or disposal overalls, boiler suits,
                       warehouse coats, laboratory coats, donkey
                       jackets, apron and specialist protective clothing
                       such as chemical suits and aluminium asbestos
                       suits for hot work. Choice  of material includes
                       non-flammable,     anti-static,  chain    mail,
                       chemically impermeable or high visibility
                       materials.

                       Selection

                       In selecting protective clothing the factors to be considered includes:
                       a)  Penetration of chemicals through seams, pores, zippers and materials
                          imperfections;
                       b)  Degradation of clothing due to exposure to chemicals, heat and sunlight; and
                       c)  Permeation of chemicals through clothing, i.e. without going through pinholes,
                          seams or other openings.
