Faceshield protection is a vital part of personal protective equipment (PPE). Employers are recognizing the added protection that faceshields provide and utilization is growing.
Eye and Face Protection Standards
The Occupational Safety and Health Administration’s (OSHA’s) regulation 29 CFR 1910.133 requires the usage of eye and face protection when workers are uncovered to eye or face hazards such as flying objects, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or doubtlessly injurious light radiation.
The original OSHA standards addressing eye and face protection had been adopted in 1971 from established Federal standards and nationwide consensus standards. Since then, OSHA has amended its eye and face protection standards on quite a few occasions.
The American National Standards Institute (ANSI) American National Normal for Occupational and Instructional Personal Eye and Face Protection Devices commonplace Z87.1 was first printed in 1968 and revised in 1979, 1989, 2003, 2010 and 2015. The 1989 version emphasized efficiency requirements to encourage and accommodate advancements in design, materials, applied sciences and product performance. The 2003 version added an enhanced user choice chart with a system for selecting equipment, such as spectacles, goggles and faceshields that adequately protect from a specific hazard. The 2010 version focused on a hazard, such as droplet and splash, impact, optical radiation, mud, fine dust and mist, and specifies the type of equipment needed to protect from that hazard. The 2015 revision continues to focus on product efficiency and harmonization with international standards. The 2015 standards fine-tune the 2010 hazard-primarily based product efficiency structure.
The majority of eye and face protection in use right now is designed, tested and manufactured in accordance with the ANSI Z87.1-2010 standard. It defines a faceshield as “a protector commonly intended to, when used at the side of spectacles and/or goggles, shield the wearer’s face, or portions thereof, in addition to the eyes from certain hazards, depending on faceshield type.”
ANSI Z87.1-2015 defines a faceshield as “a protector supposed to shield the wearer’s face, or parts thereof from certain hazards, as indicated by the faceshield’s markings.” A protector is a complete machine—a product with all of its parts of their configuration of intended use.
Though it will appear that from the faceshield definition change from 2010 to 2015 that faceshields assembly the efficiency standards of the 2015 customary can be used as standalone gadgets, all references in the modified Eye and Face Protection Selection Software seek advice from “faceshields worn over goggles or spectacles.”
When choosing faceshields, it is important to understand the importance of comfort, fit and ease of use. Faceshields should fit snugly and the first way to make sure a snug fit is thru the headgear (suspension). Headgear is normally adjustable for circumference and depth. The headband is adjusted for circumference fit and the highest band is adjusted for depth. When worn properly, the faceshield must be centered for optimal balance and the suspension should sit between half an inch and one inch above the eyebrows. Since faceshields are used together with different PPE, the interplay among the PPE needs to be seamless. Simple, easy-to-use faceshields that allow users to shortly adjust the fit are best.
Faceshield Visor Materials
Faceshield visors are constructed from a number of types of materials. These materials include polycarbonate, propionate, acetate, polyethylene terephthalate glycol (PETG) and steel or nylon mesh. It is important to select the proper visor for the work environment.
Polycarbonate materials provides the very best impact and heat resistance of all visor materials. Polycarbonate also provides chemical splash protection and holds up well in extraordinarily cold temperatures. Polycarbonate is generally more expensive than other visor materials.
Acetate provides the very best clarity of all of the visor materials and tends to be more scratch resistant. It additionally presents chemical splash protection and may be rated for impact protection.
Propionate materials provides better impact protection than acetate while additionally offering chemical splash protection. Propionate material tends to be a lower cost level than both acetate and polycarbonate.
Polyethylene terephthalate glycol (PETG) provides chemical splash protection and should provide impact protection. PETG tends to be probably the most economical option for faceshield choices.
Metal or nylon mesh visors provide good airflow for worker comfort and are typically used within the logging and landscaping trade to assist protect the face from flying debris when reducing wood or shrubbery.
Specialty Faceshield Protection
Arc Flash – These faceshields are used for protection in opposition to an arc flash. The requirements for arc flash protection are given within the National Fire Protection Association (NFPA) 70E standard. Faceshields are included in this customary and should provide protection based mostly on an Arc Thermal Performance Value (ATPV), which is measured in energy per square centimeter (cal/cm2). The calorie score have to be decided first to be able to select the shield that will provide the most effective protection. Consult with Quick Suggestions 263 NFPA 70E: Electrical Safety Abstract for more information on the proper number of PPE.
Heat and Radiation – There are faceshields that provide protection against heat and radiation. These faceshields prevent burns by filtering out intense ultraviolet (UV) and infrared (IR) radiation. They’re made from polycarbonate with special coatings. An instance of this could be adding a thin layer of gold film to extend reflectivity.
Welding – Shaded welding faceshields provide protection from UV and IR radiation generated when working with molten metal. The shades normally range from Shade 2 to14, with Shade 14 being the darkest shade. Consult with Fast Suggestions 109: Welding Safety for more info on selecting the proper welding faceshields.
PPE Hazard Assessment, Selection and Training
When selecting a faceshield or any other PPE, OSHA suggests conducting a worksite hazard assessment. OSHA provides guidelines in 29 CFR 1910 Subpart I Appendix B on the way to evaluate worksite hazards and how to select the proper PPE. After deciding on the proper PPE, employers should provide training to workers on the proper use and upkeep of their PPE. Proper hazard assessment, PPE selection and training can significantly reduce worker accidents and help to ensure a safe work environment.
