Protect your eyes with safety goggles
Safety glasses or safety goggles should be worn whenever you might come in contact with airborne debris moving at high speeds. Even simple tasks like sawing and hammering carry a risk of shooting bits of material back at your face, and if you're welding or working with a power saw, never, ever neglect to put on protective eyewear.
Characteristics of Safety Glasses
Occupational health and safety agencies recommend safety glasses with lenses made of plastic polycarbonate. Glass is not preferred because it loses its ability to resist impact if it gets scratched; if you need glasses to see properly, you can get prescription safety glasses with special polycarbonate lenses specially made. These are available in a full range of vision correction specifications, including bifocal safety glasses.
Other materials used in the lenses of safety glasses and safety goggles include regular plastic and Trivex, though neither is as versatile or durable as plastic polycarbonate. However, plastic glasses are fine if you're working with solvents, and Trivex has more impact resistance than plastic but not as much as plastic polycarbonate.
Frames should be heat-resistant and stronger than regular eyeglasses. They are also specially designed to prevent any frontal impact from pushing the lenses out of the frames and into your eyes.
Other Must-Have Head and Eye Protection Products
Proper head, hearing and eye protection is a must when you're working in any industrial area. Earplugs will go a long way to protect your hearing if you work with loud equipment, or if you're exposed to the continual droning and humming of operational machinery. A hard hat could save your life on a construction site and should be worn anywhere heavy industrial materials are being moved around.
These products should all be used in conjunction with other pieces of industrial safety clothing, such as work gloves and steel-toed work boots. Also, remember that your employer is bound by law to provide you with extensive safety training so you're prepared for any and all hazards you might encounter. If you notice a potential danger, report it right away, and keep in mind that you have the right to refuse to do any work that poses a threat to your safety, without fear of disciplinary action.
