Sight Conservation and Eye Safety LG #5 A. Your Eyes Defenses Defenses Tears Self-cleans the eyes of foreign material

Eye lid Physical barrier to some objects Cornea Damaged ones can now be replaced Inner eye (retina) Damage is irreversible B. Types of Eye Injuries

Foreign Bodies Most common of injuries Abrasions & Scratches Can cause permanent scar tissue

Contusions from large objects Irritations from fibers Particles in smoke or fumes Chemical Burns Acids Precipitate a protein barrier preventing further penetration into tissue Burn the surface of the eye and cause scars

Bases (alkalies) Damages tissue as long as there is contact Dissolves fat-soluble tissue, turning it into jelly Acids and Bases are both CORROSIVE Chemical Burns

Gases in air can burn or irritate Vapors and mists can irritate and produce scarring Paints

Pesticides Cleaners In the Navy, the most frequent eye injuries result from handling fuels without eye protection Irradiation Burns Infrared light (heat lamps) Passes through cornea-absorbed by

lens Ultraviolet light (sun, welding) Causes flash burns Delayed effects (4-6 hrs. after exposure) Infrared and Ultraviolet light can cause permanent eye damage

C. Navy Sight Conservation Program Elements Program Elements Identify eye hazards Survey all work areas to determine potential eye hazardous areas Program Elements Eliminate hazards by engineering

controls Eliminate hazards completely, where possible Reduce eye hazards Guards Isolation of the process

Substitution of a less hazardous chemical Program Elements Post eye hazardous areas Label all areas and pieces of equipment which are potentially hazardous Use yellow & black caution signs: to warn of eye hazard areas to specify eye protection required

Mark the areas around eye hazards with yellow and black striping or checkerboard tape on the deck Program Elements Provide protection Where hazards cant be eliminated or reduced, PPE is required Navy must provide all protective equipment

Protection must be specific to the job Safety Officer will determine types to be worn Medical provides eye exams and screening: for corrective needs for personnel working around radiation sources D. Eye Protection--Personal Protective Devices

Must Meet ANSI Standards Each manufacturers glasses or goggles must be tested and approved Testing includes: Impact

Permeability Shatter proofing Frame breaking strength Only ANSI approved eyewear may be used by Navy personnel Must have Z87 stamp Devices Designed for Specific Hazards

Six general types of protective eyewear Safety glasses/spectacles Chemical goggles

Welding goggles Chipping goggles Welding helmets Face shields Wear the right type!! Wearing the wrong type can be dangerous Wearing Protective Devices Wear double protection for acids and

bases Chemical goggles AND face shield ! Face shields MUST be worn with safety glasses or goggles Face shields may not be worn by themselves When working with UV light, wear protection based on level of light intensity

NO sunglasses!! Wearing Protective Devices Navy will provide prescription safety glasses See Safety Officer or MDR Regular prescription glasses CANNOT be worn as safety glasses Keep devices clean

Discard if badly scratched or damaged E. Emergency Eye Wash Stations Emergency Eye Wash Stations Must flush with fresh water for minimum of 15 minutes

Flushing is used to: Remove foreign objects Dilute strong chemicals Required wherever Corrosives are used (battery shops) Particulate hazards exist (machine shop) Eye Wash Requirements

Must meet ANSI standards Must provide continuous water flow Activated by one hand or foot motion Both hands free to hold eyes open (valve must stay open)

May be combined with deluge shower for full body chemical first aid Eye Wash Styles Plumbed into ships potable water system Portable, pressurized tank-type Gravity-fed portable self-container All covered by weekly or monthly PMS

Note : OPNAVINST 5100.19 (series), Chapter B5 provides a complete list of compartments and processes requiring an eye wash or deluge shower. F. Program Enforcement Enforcement Personnel working in eye hazardous areas MUST wear eye protection

Supervisors must set the example Visitors/guests provided with eye protection Some sports (racquetball) are hazardous. Wear sport goggles Encourage personnel to wear eye protection at home (hobbies/lawn work) G. Eye Injury First Aid

First Aid Never rub eyes to remove particulates Chemical burns Flush for 15 minutes (minimum) Get medical attention! Punctures and trauma Cover with a clean, soft cloth Get medical attention!

First Aid Report ALL minor cuts and eye problems to medical Minor scratches may lead to potential infections with resulting scar tissue formation, loss of sight, or other significant damage
