Faceshield protection is a crucial 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 use of eye and face protection when workers are uncovered to eye or face hazards corresponding to flying objects, molten metal, liquid chemical substances, acids or caustic liquids, chemical gases or vapors, or probably injurious light radiation.
The original OSHA standards addressing eye and face protection were adopted in 1971 from established Federal standards and nationwide consensus standards. Since then, OSHA has amended its eye and face protection standards on numerous occasions.
The American National Standards Institute (ANSI) American National Normal for Occupational and Educational Personal Eye and Face Protection Devices normal Z87.1 was first printed in 1968 and revised in 1979, 1989, 2003, 2010 and 2015. The 1989 version emphasised efficiency requirements to encourage and accommodate advancements in design, materials, applied sciences and product performance. The 2003 version added an enhanced user selection chart with a system for selecting equipment, similar to spectacles, goggles and faceshields that adequately protect from a selected hazard. The 2010 model focused on a hazard, reminiscent of droplet and splash, impact, optical radiation, dust, fine mud and mist, and specifies the type of equipment wanted to protect from that hazard. The 2015 revision continues to focus on product efficiency and harmonization with world standards. The 2015 standards fine-tune the 2010 hazard-based product performance structure.
Nearly all of eye and face protection in use at this time is designed, tested and manufactured in accordance with the ANSI Z87.1-2010 standard. It defines a faceshield as “a protector commonly meant to, when used along with spectacles and/or goggles, shield the wearer’s face, or portions thereof, in addition to the eyes from certain hazards, relying on faceshield type.”
ANSI Z87.1-2015 defines a faceshield as “a protector meant to shield the wearer’s face, or portions thereof from sure 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 meant use.
Though it could seem that from the faceshield definition change from 2010 to 2015 that faceshields meeting the efficiency criteria of the 2015 normal can be utilized as standalone units, all references in the modified Eye and Face Protection Selection Device refer to “faceshields worn over goggles or spectacles.”
Faceshield Selection
When choosing faceshields, it is very important understand the importance of comfort, fit and ease of use. Faceshields ought to fit snugly and the first way to make sure a snug fit is thru the headgear (suspension). Headgear is often adjustable for circumference and depth. The headband is adjusted for circumference fit and the top band is adjusted for depth. When worn properly, the faceshield ought to be centered for optimal balance and the suspension ought to sit between half an inch and one inch above the eyebrows. Since faceshields are used along side different PPE, the interaction among the PPE must be seamless. Simple, simple-to-use faceshields that permit users to rapidly 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 metal or nylon mesh. It is important to select the proper visor for the work environment.
Polycarbonate materials provides the perfect 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 different visor materials.
Acetate provides the perfect clarity of all of the visor supplies and tends to be more scratch resistant. It also presents chemical splash protection and could also be rated for impact protection.
Propionate material provides higher impact protection than acetate while additionally offering chemical splash protection. Propionate materials tends to be a lower cost point than both acetate and polycarbonate.
Polyethylene terephthalate glycol (PETG) offers chemical splash protection and will provide impact protection. PETG tends to be the most economical option for faceshield choices.
Steel or nylon mesh visors provide good airflow for worker comfort and are typically used in 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 Affiliation (NFPA) 70E standard. Faceshields are included in this standard and should provide protection based mostly on an Arc Thermal Performance Worth (ATPV), which is measured in energy per square centimeter (cal/cm2). The calorie rating should be determined first as a way to choose the shield that can provide one of the best protection. Refer to Quick Suggestions 263 NFPA 70E: Electrical Safety Abstract for more data on the proper selection 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 are made from polycarbonate with special coatings. An example of this can 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 often range from Shade 2 to14, with Shade 14 being the darkest shade. Seek advice from Fast Ideas 109: Welding Safety for more data on choosing the proper welding faceshields.
PPE Hazard Evaluation, Selection and Training
When selecting a faceshield or every other PPE, OSHA suggests conducting a worksite hazard assessment. OSHA provides guidelines in 29 CFR 1910 Subpart I Appendix B on methods to consider worksite hazards and tips on how to select the proper PPE. After choosing the proper PPE, employers must provide training to workers on the proper use and maintenance of their PPE. Proper hazard assessment, PPE choice and training can significantly reduce worker injuries and assist to make sure a safe work environment.
