PROTECTIVE CLOTHING …consideration of the options available for protecting the skin against health hazards
BACKGROUND • skin: first point of contactprotection • prevalent occupational disease • significant decline in post-OSHA era • problems continue
PREVENTION OF OCCUPATIONAL DERMATOSES • pre-placement examinations • ventilation aspects • cleanliness • protective clothing • protective ointments (barrier creams)
PRE-PLACEMENT EXAMS • careful examination of skin by physician • obtain history of skin disease • caution with pre-employment patch test • Unlikely to help predict allergies • Might cause skin problemsliabilities • to large extent, the employee becomes his/her own reference point
VENTILATION • dilution and LEV used primarily to protect against inhalation hazards • side benefit is the positive impact on general cleanliness • minimization of settled contaminants
CLEANLINESS • …of person, clothes, workplace • most important single factor • clean-up of machines, tools • general housekeeping (floors, walls, ceiling, rafters, etc.) • skin and clothing • washing, shower and locker facilities
PROTECTIVE CLOTHING • “body suits” • long coats • jackets & pants • aprons • boots • gloves
PROTECTIVE MATERIALS • natural rubber • neoprene • polyvinyl alcohol • nitrile • butyl • leather • others
DEFINITIONS • breakthrough time • penetration • permeation • degradation
SPECIAL CONSIDERATIONS • permeability • contamination of inside of clothing • regular cleaning • routine inspection
EPA/NIOSH ENSEMBLES • Level A: SCBA, totally encapsulating suit, gloves, chemical boots, + • Level B: SCBA, hooded chemical-resistant suit, gloves, chemical boots, + • Level C: full-face or half-face APR, hooded chemical-resistant suit, + • Level D: no respirator, coveralls, gloves, boot coverings, +
PROTECTIVE OINTMENTS • “vanishing cream” types facilitate removal of chemical • water-repellant (lanolin, wax, silicone) • oil-repellant (methyl cellulose, silicates) • “light screens” protect against UV • special “reactive ingredient” types • particularly useful with gloves
DESIRABLE PROPERTIES • protective ointments: • non-irritating • non-sensitizing • easily applied • adhere to skin during work activity • removed easily after completion of work
