Your Eyes are Important - Protect Them

Your Eyes are Important - Protect Them

Tools are designed for specific uses. Using any tool inappropriately is a recipe to disaster. To avoid personal injury and tool damage, selecting the proper tool and correct Personal Protection Equipment *(PPE)* to do the job safely, is essential.
Safety glasses and goggles are designed to prevent dust, debris, wood shavings, chemicals etc, from getting into the eyes. Safety glasses are one of the most basic pieces of safety equipment that must and should be used when working with tools.

*You should consider the following when evaluating safety eyewear:*

’¢ What hazards are you subject to?

’¢ Should you choose safety glasses or safety goggles? Is one more comfortable or appropriate to the hazards you might face?

’¢ Do you need clear or prescription safety glasses? If you need corrective lenses, should you use your own or use corrective safety eye protection?

The primary consideration should always relate to having the best protection against the potential workplace threats you face on a daily basis. When considering the potential hazards you may face at work or at home, you must be both honest and thorough in your evaluation of the threat.

Accidents and eye protection ’“ *60%* of accidents resulted from workers not wearing any protection ’“ *40%* resulted from wearing the wrong type of eye protection.
Flying objects, particles, and sparks ’“ around *70%* of all eye accidents resulted from airborne particles.

Site work and machinery operation ’“ over *40%* of injuries happened to skilled workers (mechanics, carpenters, plumbers, etc.) ’“ around *20%* of accidents occurred with unskilled workers ’“ around *50%* of the workers were in manufacturing and more than *20%* were involved in the construction industry.

No eye protection training ’“ almost *40%* of injured workers received no eye protection training.

Chemical contact ’“ causes about *20%* of all eye injuries in the workplace.
The choice of safety glasses is just as important as their use. Identify the risk in your job situation and use protective eyewear that is appropriate for your job.

The five major dangers to your eyes:
’¢ Impact ’“ Flying objects and particles.
’¢ Heat ’“ Anything that gives off dangerous heat.
’¢ Chemicals ’“ Includes flashes, fumes, and vapours.
’¢ Dust ’“ Otherwise harmless particulates that can damage sensitive eyes.
’¢ Optical radiation ’“ Everything from simple glare to intense light.

When it comes to protecting your eyes, you can't be too careful. Especially when you are around power tools or machinery that has the potential to throw debris out.
Safety glasses are designed to protect your eyes from airborne particles that can sneak into your eyes from the side or over the top of your lenses. What's more, protective eyewear is designed for a tougher work environment, and must meet rigorous *EN166* standards for strength and durability.

*European Standards for Eye Protection.*

All manufacturers of safety eyewear are required to have their products independently tested against a European standard. Firstly it is important to remember that both the Frame and Lens are tested, therefore both must include the *CE* symbol and the manufacturer's logo. The *CE* marking certifies that a product has met *EU* consumer safety, health or environmental requirements.

*Frame Markings.*

The frame will usually be marked on the inside of both arms. All safety frames must pass the European *EN166* standard. This is a higher standard that the *US* or *Asian* equivalent and can often be preceeded by *BS* which is simply the direct British equivalent. If this is not stamped on the frame then you best to steer clear. Next will be a numbers and/or letters which indicate to what degree the frames passed the *EN166* test within various categories.

*Shape or design of the frame to...*

3 - Protect against liquid droplets and splashes. This is usually only found on goggles where a full seal is made around the eyes.
4 - Protect against large dust particle over 5 microns in size.
5 - Protect against dust and fine dust particles smaller that 5 microns.

*Strength of the frame to...*

S - Withstand impacts against small objects travelling up to 12 meters per second
F - Withstand impacts against small objects travelling up to 45 meters per second
B - Withstand impacts against small objects travelling up to 120 meters per second
A - Withstand impacts against small objects travelling up to 190 meters per second
T - Withstand impacts at extreme temperatures

A frame can have a combination of markings but using the example above, the glasses are called Contour and they have the official safety *'Crown'* seal of the accredited Manufacturer Bolle. They adhere to the *EN166* standard but do not protect against liquid splashes, fine particles or dust since there is no number. The letters *'F'* and *'T'* then indicate they are capable of withstanding impacts from small objects travelling no faster than 45m/s even at extreme temperatures.

*Lens Markings*

Unlike the frame, lenses can meet various safety standards including *EN166, 169, 170 & 172.* For obvious reasons the manufacturers are not required to print every standard on the lens but simply the degree to which they meet the standard. Using the guide below you can determine which standards they meet. Once again the manufacturers seal and the *CE* mark are mandatory. In addition will be a degree of solar or *UV* radiation protection, the optical quality and then the mechanical strength.
Radiation Protection:
2 - *UV* Protection *(EN170)*. The number 2 indicates the filter may effect colour recognition
2C or 3 - *UV* Protection *(EN170)*. The number 2C (previously 3) indicates the filter allows good colour recognition
4 - Infrared Protection *(EN171)*. i.e. Protection from heat
5 - Solar Protection *(EN172)*. i.e. *100% UV* sunglare protection - with no infrared *(IR)* protection
6 - Solar Protection *(EN172)*. i.e. *100% UV* sunglare protection - with infrared *(IR)* protection

*Lens Shading:*

1.2 - Allows more than 74.4% light transmission, but less than 100%
1.7 - Allows more than 43.2% light transmission, but less than 58.1%
2.5 - Allows more than 17.8% light transmission, but less than 29.1%
3.1 - Allows more than 8.0% light transmission, but less than 17.8%

*Optical quality:*
1 - Class 1 High optical, quality suitable for regular use. Refractive power of ± 0.06 dioptres.
2 - Class 2 Medium optical, quality suitable for occasional use. Refractive power of ± 0.12 dioptres
3 - Class 3 Low optical, quality suitable for exceptional use. Refractive power of ± 0.25 dioptres

*Strength of the lens to...*

F - Withstand impacts against small objects travelling up to 45 meters per second
B - Withstand impacts against small objects travelling up to 120 meters per second
A - Withstand impacts against small objects travelling up to 190 meters per second
T - Withstand impacts at extreme temperatures
