In this post, we give a quick primer on how arc flash face shields work. When an arc flash occurs, there is a sudden release of energy that can cause serious burns. The face shield helps to protect your face and eyes from that intense heat and light. Or so, that is the intended purpose.
What is an arc flash?
An arc flash is a type of electrical explosion that results from a low-impedance connection between electrical conductors. This can happen when two wires touch or when a conductor comes into contact with a conducting surface. When an arc flash occurs, there is a sudden release of energy that can cause serious injury, death, and damage to property.
What are the dangers of an arc flash?
There are many dangers associated with an arc flash, including severe burns, blindness, and even death. An arc flash is a type of electrical explosion that occurs when there is a sudden release of energy from an electrical circuit. This release of energy can create a bright light that can cause severe burns, as well as a loud noise that can cause hearing damage. Additionally, the heat from an arc flash can be so intense that it can start fires or cause explosions.
How do arc flash face shields work?
Arc flash face shields are made of a clear and durable material that is designed to protect your face from the bright light and heat of an arc flash. The material is also flame resistant, so it will help protect you from the fire that can result from an arc flash. Arc flash face shields typically have a ratchet headgear system that allows you to adjust the fit of the shield to your head, and they also have an anti-fog coating to help keep your vision clear.
It’s important to make sure that the shield is properly rated for the level of protection you need.
What are the benefits of using an arc flash face shield?
Arc flash face shields are designed to protect your face from the bright light and heat of an arc flash. There are many benefits to wearing them, mostly due to the types of materials they are made of and how they fit over the face.
These shields are made of a special material that is transparent to visible light but opaque to infrared radiation. Arc flash face shields also have a coating that reflects back some of the heat generated by an arc flash. Most arc flash face shields are made of clear polycarbonate and are fitted with a headgear system that helps keep the shield in place during use.
The face shield protects the wearer’s eyes and face from the intense heat and light generated by an arc flash. Some arc flash face shields also have a built-in ventilation system that helps to keep the wearer’s face cool and protect against smoke inhalation.
How to choose the right arc flash face shield?
Choosing the right arc flash face shield is important to ensure your safety while working with electrical equipment. Here are some factors to consider when making your selection:
- The size of the face shield. Make sure the face shield covers your entire face, from your forehead to your chin.
- The level of protection you need. The level of protection is indicated by the “Arc Rating”, measured in calories per centimeter squared (cal/cm2). The higher the Arc Rating, the more protection the face shield provides.
- The weight of the face shield. A heavier face shield may be more comfortable to wear, but it can also be more difficult to keep in place while working.
- The durability of the face shield. Look for a face shield that is made from durable materials and that has a protective coating to resist scratching and other damage.
How to use an arc flash face shield?
To use an arc flash face shield, simply hold it up to your face and look through the clear part of the shield. The reflective coating on the shield will reflect back some of the light and heat generated by the arc flash, protecting your eyes and skin from injury.
How to care for an arc flash face shield?
You should inspect your face shield before each use. Check for cracks, damage, and debris. Clean the face shield with soap and water, or a mild detergent if it is particularly dirty. You should also check the manufacturer’s instructions for any specific cleaning or care instructions.
It is important to store your face shield properly when you are not using it. Be sure to keep it in a clean, dry place away from direct sunlight. You should also avoid storing it near chemicals or other materials that could damage the face shield.
FAQs about arc flash face shields
Q: Do I need an arc flash face shield if I already wear a hard hat and safety goggles?
A: It depends on the hazard level of the task you are performing. The National Electric Code (NEC) requires workers to wear arc flash PPE when working on or near energized electrical equipment. An arc flash assessment should be conducted to determine the necessary level of PPE, which could include an arc flash face shield.
Q: Can I buy an arc flash face shield that will protect me from all hazards?
A: No, there is no such thing as a universal PPE solution. The type of PPE you need depends on the hazard you are exposed to. You should always consult with a qualified safety professional to determine the appropriate PPE for your specific needs.
Q: How do I know if an arc flash face shield will fit over my safety glasses?
A: Most manufacturers offer sizing information on their websites or product packaging. If you have questions about whether a particular face shield will fit your safety glasses, you can always contact the manufacturer directly.
Q: How long will an arc flash face shield last?
A: With proper care and storage, an arc flash face shield can last for many years. However, inspecting your PPE regularly for signs of wear and tear is important. If you have any doubts about the condition of your PPE, it should be replaced immediately.
Wearing an arc flash face shield is one of the best ways to protect yourself from this type of accident. So if you work in an industrial setting, be sure to ask your employer about getting one for yourself.
