  2. DESCRIBE the selection criteria for personal protective clothing and equipment DESCRIBE the cause, effects and prevention of occupational dermatitis. ENABLING OBJECTIVES

  3. REFERENCES: (a) NSTM, CH 074, VOL 3, GAS FREE ENGINEERING (b) NTTP 3-20.31, SURFACE SHIP SURVIVABILITY (c) NSTM, CH 077, PERSONNEL PROTECTION EQUIPMENT (d) OPNAVINST 5100.19 (series), NAVOSH MANUAL (e) 29 CFR 1900 (SERIES)

  4. SELECTING PROTECTIVE CLOTHING/EQUIPMENT • TURN TO APPENDIX H, NSTM 074 VOL. 3

  5. OCCUPATIONAL DERMATITIS • What is it? • Inflammation of the skin • Results from exposure to irritants in the work environment • May be slight reddening of the skin with mild itching • Rash • Small eruptions with intense itching • What causes it?

  6. CAUSES OF SKIN PROBLEMS • CHEMICAL • Most frequent cause of dermatitis • Acts as primary skin irritant • Differs in two respects: • Reaction Time • Mode of Action • Mists, vapors, diluted or full strength • MECHANICAL • Friction • Pressure • Results in abrasions, wounds, bruises • Introduces foreign bodies into skin • Examples: Falling on Non-Skid, Air Nozzle • BIOLOGICAL AGENTS • Bacteria, viruses, fungi, and insects • Complicates dermatitis • Examples: Bee stings, Athlete’s foot • Not all skin reacts in the same way or to the same degree to causes

  7. FACTORS INFLUENCING SKIN REACTION • TYPE OF SKIN • Pigmentation • Dryness • Hairiness • SEX OF THE PERSON • Women have more sensitive, less oily skin than men • AGE • Affects younger personnel more

  8. FACTORS INFLUENCING SKIN REACTION • TEMPERATURE EXTREMES • More prevalent in warm weather • Risk of direct contact is greater due to less clothing worn • Excessive perspiration - skin is more vulnerable • Low winter temps cause dry, chapped skin causing cracks

  9. FACTORS INFLUENCING SKIN REACTION • EXCESSIVE OILINESS/DRYNESS • Naturally oil skins are less likely to incur dermatitis when working with fat solvents • More susceptible to substances that remove oil • Dry skin cracks easily, especially around alkalis and solvents • Cracked skin makes skin subject to infections • LACK OF CLEANLINESS • ALLERGIES

  10. EASIER TO PREVENT THAN TO CURE

  11. PREVENTION • Chain of command support • Hazardous awareness training • Personal cleanliness • Eliminate contact • Identify hazards • Good housekeeping • Instruction • Barrier creams

  12. NSTM 074, VOL 3 • Person working with irritants, caustics, or toxic materials shall wear • Protective Coveralls • Gloves • Boots

  13. AS THE GFE, ENSURE PERSONNEL ARE PROPERLY PROTECTED • COVERALLS, GLOVES, AND BOOTS MAY NOT BE ENOUGH!!!! REMEMBER - SIGHT HEARING PHYSICAL PROTECTION

  14. EYE AND FACE PROTECTION • Face shields • Can accommodate respiratory protection devices • Safety Goggles/Glasses • Chemical • Plastic Perforated • Welding/Chipping • Tinted • Wire

  15. HAND PROTECTION

  16. HAND PROTECTION • Natural-Latex • Resistant against acids, caustics, abrasion from sand blasting, grinding • General Purpose Use • Butyl Rubber • Resistant to Toxic chemicals, gases, water vapor, oxidation, and ozone attack • Neoprene Rubber • Oils, greases, petroleum, tear resistant

  17. Milled Nitrile Use where sense of touch is a must Stand up to mechanical abuse Natural Rubber Good pliability over large temperature range Long term resistance to chemicals & acids Vinyl Coated Chemical & abrasion resistant Use for handling oils, acids, caustics, most solvents HAND PROTECTION

  18. HEAD PROTECTION • Helmets/Hardhats protect crewmembers from: • Falling and flying debris • Impact with low overheads

  19. HEARING PROTECTION All hands shall comply with hazardous noise labels Wear assigned hearing protective devices Insert Earplug Circumaural Muffs

  20. BODY PROTECTION/COVERALLS • Should provide comfort of movement • Selection and way it protects wearer vary from vendor to vendor • Should not be plastic for GFE evolutions (Causes static electricity)

  21. SAFETY SHOES AND BOOTS • Water resistant leather • Heels and soleshave treads • Non-marking • Non-sparking • Water/Fuel resistant • Steel toe Chukka

  22. MISCELLANEOUS PROTECTION • Chemlites • Flashlight • Harness/lifelines • Communications • Personal Alert Safety System “PASS” • PRE-Alert signal 7-10 sec prior to alarm PASS uses 2 “AA” batteries

  23. ANY QUESTIONS?

  24. SUMMARY • We described the selection criteria for personal protective clothing and equipment • We described the cause, effects and prevention of occupational dermatitis.
