Selecting Best Eye Protection over glasses
It is common knowledge to use eye protection in places where eye hazards do exist. Its should be made clear that normal glasses do not offer the correct eye protection in any workplace because they do not meet the set standard of eye protection. However, in the world, over a thousands people become victims of eye injuries with over 2000 workers completely losing their eyesight.
In fact workers using the wrong protection have been identified to incur injuries as much as those workers who are not using any protection.
There are a couple of hazards that may cause eye injuries at work places. These hazards are categorized to identify the specific eye protection that should be used on a specified hazard.
There are different ways that a worker can injure their eyes especially in a construction site. Nails, metal shavings splinters can be flying in the air, mixing of cement, sawing, grinding, and chipping products dusts and grits. So does heavy machinery moving across a site. With so many ways to injure our eyes we are fortunate that we have also so many ways to protecting them.
When we evaluate the hazards in our work area we must consider the hazards that can harm our eyes and select a proper way to protect them.
Types of Over Glasses Eye Protection:
Safety Glasses or Goggles:
They are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. Many projects require everyone to wear safety glasses rated ANSI Z87. Used when there is possibility of substance splash or airborne particles. Safety glasses or goggles are intended to shield the wearer’s eyes from impact hazards such as flying fragments, objects, large chips, and particles. Workers are required to use them with side shields when there is a hazard from flying objects. Non-side shield spectacles are not acceptable eye protection for impact hazard
A face shield is a device used to protect wearer’s entire face (or part of it) from impact hazard such as flying objects and road debris, chemical splashes (in industry), or potentially infectious fluid (in medical). When worn alone, face shields do not protect employees from impact hazards. Use face shields in combination with safety spectacles or goggles, even in the absence of dust or potential splashes, for additional protection beyond that offered by spectacles or goggles alone.
Cutting and Welding Eye Protectors:
For all types of electric arc processes, a welding helmet complying with ANSI Z87.1, equipped with the correct shade filter, is required to ensure proper vision protection.
Types Of Eye Hazards
There are impact hazards, optical radiation hazards and splash hazards that pose a threat to your eyes.
Let’s look at ways of using eye protection to avoid injuries in the three hazard categories.
A splash hazard can occur from a hot or cold spatter of hazardous liquid, mist or powder. The regular kind of spectacles cannot offer eye protection from splash hazards as they only cover a small area around your eyes.
If you work in a place where splash hazards do exist be sure to ask for splash goggles from your company’s safety department.
If you are working from home, you can use Splash goggles, which are common eye protection device.
They are mostly used to protect laboratory technicians from chemical hazards.
They are capable of indirect ventilation that allows air flow without letting powder, or liquid spray to get into your eyes.
If you are buying one for yourself, be sure to get one that features an anti-fog coating that gives you a clear vision without moisture condensation.
This is caused mostly by UV, infrared and visible radiation. Over exposure to any of these elements can lead to eye problems.
If you work in such conditions where there are optical radiations, you can go for specific filter eye protection lenses that prevent any optical radiation encounter.
The aim here is to identify the element and use the right eye protection lenses.
In most cases, UV blocking spectacles will work, but if there are high levels of hazardous radiation, it might be a good idea to use goggles with filtering lenses
Since you are going to work for long hours while wearing those eye protection goggles, choose the comfortable ones to put on.
These are the most common kinds of eye hazards that can happen at home or even in work places. They include explosions, flying particles among others.
The best eye protection device to use for this kind of hazard is clear spectacles.
Whether you are going for non prescription or prescription spectacles, be sure to pick those that offer side protection. You should also pick spectacles fit you well and come with the right lens coating.
There are a variety of lenses such as chemical attack resistant and abrasion resistant lenses to mention but a few. Wearing safety goggles will give you sufficient protection from impact hazards.
As much as we are observing best eye protection methods we can not eliminate the need to have also a eyewash station in the workplace incase the eye comes in contact with the chemicals and there is need to do an eye wash before going for a fast aid.
Let see all the emergency eyewash shower requirements for best eye protection.
If an employee get foreign particles in the eyes or a chemical spill on the body, an emergency eyewash station or deluge shower is the most important initial step in first aid treatment. Chemical burns to the eye are among the most urgent of emergencies.
An eyewash/shower is required if:
• The Safety Data Sheet indicates a chemical in use is caustic, toxic, or corrosive.
• The SDS informs that serious eye damage may result.
• Warnings such as “causes chemical burns” or “causes permanent eye damage” are posted on container labels. Eyewash /showers in addition must have the following:
• Pure clean water
• Hands free operation
• Constant water flow rate for a full 15 minutes
• Highly visible markings and signs
• Unobstructed access
Accessibility: The single most important treatment for chemically-burned eyes is copious irrigation within seconds of injury. This means that victims should not have to climb over or around obstacles to find the eyewash station. Make sure there are no barriers to the unit.
Clean, Functional Equipment: Deluge showers should be inspected often to insure they function properly with adequate water flow, and are clean and sanitary. Portable eyewash units are an option in areas where plumbed in water is not accessible or of high enough quality. Portable units also need an anti-bacterial additive to ensure proper water sanitation. Flushing with any water is better than none, but purified water reduces potential for secondary eye infections.
Training in Proper Use: Employees who are exposed to possible chemical splashes must know in advance how to use eyewash /deluge station properly and especially new employee in an organisation training will reduce the risks involved.
Immediately after the accident:
• Flood the eye with water or eyewash solution, using fingers to keep the eye open as wide as possible.
• Water may be colder than body temperature, which can be uncomfortable, but it is imperative to irrigate for the recommended period of time.
• Roll the eyeball as much as possible, to remove any loose particles retained under the eyelids. Do not put anything except water into the eyes to remove particles
• The eyes should be irrigated for at least 15 minutes, and the victim transported to a medical facility immediately.
• Continue irrigation of eyes during transport.
• The best way to accomplish this may be to have a portable eye-wash system ready that can be carried along.
With all those eye protection tips above, you will be able to choose the right eye protection device for the right kind of hazard.
Remember to first perform an eye safety analysis so as to identify the kind of eye hazard that exists at your place of work. Afterwards you will be able to use the right eye protection device.
Finally, you can also use your own sound judgment to determine the best eye protection for a particular situation.
