Safety use of impact-resistant safety glasses

Classification of Eye and Face Protection Products There are various types of eye and face protection products available, each designed to protect different areas of the face and eyes from specific hazards. These products can generally be categorized into protective glasses and protective masks, depending on their function and design. 1. The Role and Types of Protective Glasses Protective glasses are essential in preventing eye injuries caused by a wide range of harmful substances, such as impact, radiation, and chemicals. They come in different forms, including regular, side-protected, open, and closed designs, each suited for different working environments. Protective masks, on the other hand, are used to shield the eyes and surrounding facial area—including the neck—from hazardous materials. These include handheld, head-mounted, full-face, and half-face masks, each offering varying levels of protection based on the risk involved. Impact Safety Glasses Impact safety glasses are specifically designed to guard against high-speed particles that may cause eye damage. They are commonly used in industries like machining, construction, and manufacturing, where there is a risk of flying debris or splatter. Here are five common types of eye protection products: 1. **Plexiglas Glasses (Eye Mask)** These glasses offer excellent transparency, toughness, and resistance to low temperatures. They are lightweight and have ten times the impact strength of regular glass. However, they are not very heat-resistant and have poor scratch resistance. They are ideal for tasks like metal cutting, polishing, and grinding. 2. **CR-39 Glasses (Eye Mask)** CR-39 is a type of plastic lens known for its good strength and performance. It is lightweight, impact-resistant, and has excellent wear resistance, second only to glass. 3. **Steel Double Yarn External Net Protective Glasses** This type features a double-layer frame with an inner layer of flat glass lenses and an outer layer of steel wire mesh. The outer frame can be adjusted for better visibility when needed. It is suitable for metal cutting and grinding but should not be used in high-temperature or electrical hazard areas. 4. **Tempered Glass Glasses** Made by heating ordinary glass to 800°C–900°C and then rapidly cooling it, tempered glass significantly increases impact resistance. If broken, it does not shatter into sharp pieces, making it a safer option for industrial use. 5. **Other Materials** Some eye and face protectors are made from aluminum or 16-gauge green wire mesh. These are often used in construction, road building, and blasting operations. The performance of anti-impact glasses must meet the requirements outlined in GB5890-1986 standards. Selecting and Using Eye and Face Protection Products To ensure worker safety, employers must choose and use appropriate protective equipment according to established regulations. The former State Economic and Trade Commission issued guidelines in 2000 to help companies comply with labor laws and provide safe working conditions. When selecting eye and face protection products, users should look for items that meet national safety standards, have complete labeling, and come with recent inspection reports. Different protection needs require different product choices. 1. Choose the right level of protection based on the task. Level 1 and Level 2 impact-resistant glasses are marked as Gl and G2, respectively. 2. Before use, check that all parts are functional and the lenses are clear. Replace any damaged or worn-out equipment immediately. 3. Keep the glasses clean and avoid exposure to chemicals, heat, moisture, or direct sunlight, which could reduce their effectiveness. Ensuring proper use of eye and face protection is crucial for maintaining a safe and healthy work environment.
