Causes of Eyes Injuries

70% eye injuries were caused by flying or falling objects or sparks

striking the eyes.

One-fifth of eye injuries were resulted from contact with chemicals

Other eye injuries are caused by objects swinging from a fixed or

attached position, like tree limbs, ropes, chain or tools which were

pulled into the eye while the worker was using them.

Dust and other flying particles, such as metal shavings or sawdust.

Molten metal that might splash

Acids and other caustic liquid chemicals (sodium hydroxide) that might

splash

Blood and other potentially infectious body fluids the might splash,

spray or splatter.

Intense light such as that created by welding and lasers.

Storage and Care

Always follow manufacturer’s guidance for cleaning, storage and care.

Store to prevent scratching and damage.

Do not store equipment with potential exposure to high heat or direct

sunlight.

Inspect prior to use.

Damaged or broken equipment should be discarded.

Lenses that are pitted or deeply scratched are more prone to break under

impact and should be replaced.

Clean eye and face protection according to the manufacturer’s

instructions. If the manufacturer’s instructions are not available, clean

with a mild soap and water solution and rinse thoroughly and allow to air

dry.

PPE that has been previously used by other personnel should be

Common Causes of Eye Injuries

• Chemical splashes
• Blood or OPIM splashes or

sprays

• Intense light
• Dust and other flying particles
• Molten metal splashes

Construction workers

Laboratory workers

Technical skilled trades

Warehouse workers

Eyes Protection Safety

There are four things you can do to protect your eyes from injury:

1. Know the eye safety dangers at your work.
2. Eliminate hazards before starting work by using machine guards, work screens or

other engineering controls.

3. Use proper eye protection.
4. Keep your safety eyewear in good condition and have it replaced if it becomes

damaged

Safety Glasses

Much stronger and more resistant to impact and heat than regular glasses

Equipped with side shields that give you protection from hazards that may not be

directly in front of you

Safety glasses should be ANSI Z-87.1 approved to meet OSHA regulations

Should fit comfortable on face through all job tasks. Ensure that glasses are not

too big or too tight

Limitation

Does not seal around eyes, could allow small droplets to come in contact with eyes

Goggles and Its Types

Direct-ventilated

Indirect-ventilated

Non-ventilated

Does not allow the passage

of air into the goggle

Prevents splash entry

May fog and require

frequent lens cleaning

Prevents fogging by

allowing air

circulation

Protects against

liquid or chemical

Resist direct

passage of large

particles into the

goggle

Prevents fogging by

allowing air

Protect eyes, and the facial area immediately surrounding the eyes

from

impact, dust, splashes.

Some can be used over corrective lenses, if they fit them.

Face Shield

Grinder Use Welder Use

Chemical Use

Face Shield

Protect face from nuisance dusts and potential splashes or sprays of hazardous

liquids

Shields do not protect from impact hazards unless so rated

Shields are for face protection, not eye protection.

To protect the eyes, wear safety glasses with side shields, or goggles under the

face shield.

Welding shields

Protect eyes from burns caused

by:

Infrared light

Intense radiant light

Protect eyes and face from

flying sparks, metal spatter,

and slag chips

Laser safety goggles

Provide protection from hazards:

physical contact such as flying

particles ultraviolet light, laser,

and welding

Arc Rays

Arc rays can injure eyes

and burn skin

The welding arc is brighter

than the sun

Precaution must be taken

to protect your eyes and

skin from UV radiation

Wear correct eye and body

protection

Here’s a good example of a welder wearing all

the proper welding protection

• Always wear effective eye protection
• Training and education
• Maintenance of eye protection devices
