Faceshield protection is an important part of personal protective equipment (PPE). Employers are recognizing the added protection that faceshields provide and usage is growing.
Eye and Face Protection Criteria
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 exposed to eye or face hazards akin to flying objects, molten metal, liquid chemicals, acids or caustic liquids, chemical gases or vapors, or probably injurious light radiation.
The unique OSHA standards addressing eye and face protection had been adopted in 1971 from established Federal standards and national consensus standards. Since then, OSHA has amended its eye and face protection standards on numerous occasions.
The American National Standards Institute (ANSI) American National Standard for Occupational and Instructional Personal Eye and Face Protection Gadgets standard Z87.1 was first printed in 1968 and revised in 1979, 1989, 2003, 2010 and 2015. The 1989 model emphasised efficiency necessities to encourage and accommodate advancements in design, supplies, technologies and product performance. The 2003 model added an enhanced consumer choice chart with a system for selecting equipment, resembling spectacles, goggles and faceshields that adequately protect from a specific hazard. The 2010 version targeted on a hazard, similar to droplet and splash, impact, optical radiation, dust, fine dust and mist, and specifies the type of equipment wanted to protect from that hazard. The 2015 revision continues to deal with product efficiency and harmonization with international standards. The 2015 standards fine-tune the 2010 hazard-based product efficiency structure.
The vast 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 supposed to, when used along side spectacles and/or goggles, shield the wearer’s face, or portions thereof, in addition to the eyes from sure hazards, relying on faceshield type.”
ANSI Z87.1-2015 defines a faceshield as “a protector meant to shield the wearer’s face, or parts thereof from sure hazards, as indicated by the faceshield’s markings.” A protector is a whole machine—a product with all of its parts of their configuration of intended use.
Though it might seem that from the faceshield definition change from 2010 to 2015 that faceshields meeting the efficiency criteria of the 2015 commonplace can be used as standalone units, all references within the modified Eye and Face Protection Choice Instrument seek advice from “faceshields worn over goggles or spectacles.”
Faceshield Choice
When selecting faceshields, you will need to understand the significance of comfort, fit and ease of use. Faceshields ought to fit snugly and the first way to make sure a comfortable 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 should sit between half an inch and one inch above the eyebrows. Since faceshields are used along with different PPE, the interplay among the many PPE needs to be seamless. Simple, straightforward-to-use faceshields that allow users to rapidly adjust the fit are best.
Faceshield Visor Supplies
Faceshield visors are constructed from a number of types of materials. These supplies embrace polycarbonate, propionate, acetate, polyethylene terephthalate glycol (PETG) and steel or nylon mesh. You will need to select the proper visor for the work environment.
Polycarbonate material provides the most effective impact and heat resistance of all visor materials. Polycarbonate also provides chemical splash protection and holds up well in extremely cold temperatures. Polycarbonate is usually more costly than other visor materials.
Acetate provides the perfect clarity of all of the visor supplies and tends to be more scratch resistant. It also offers chemical splash protection and may be rated for impact protection.
Propionate materials provides higher impact protection than acetate while additionally providing chemical splash protection. Propionate material tends to be a lower cost point than each acetate and polycarbonate.
Polyethylene terephthalate glycol (PETG) provides chemical splash protection and may provide impact protection. PETG tends to be 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 business to assist protect the face from flying debris when reducing wood or shrubbery.
Specialty Faceshield Protection
Arc Flash – These faceshields are used for protection against 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 must provide protection based mostly on an Arc Thermal Efficiency Value (ATPV), which is measured in energy per sq. centimeter (cal/cm2). The calorie ranking should be determined first with the intention to select the shield that will provide the very best protection. Refer to Quick Tips 263 NFPA 70E: Electrical Safety Abstract for more information on the proper number of PPE.
Heat and Radiation – There are faceshields that provide protection in opposition to heat and radiation. These faceshields forestall 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 normally range from Shade 2 to14, with Shade 14 being the darkest shade. Seek advice from Fast Tips 109: Welding Safety for more data on selecting the proper welding faceshields.
PPE Hazard Evaluation, Selection and Training
When choosing a faceshield or another PPE, OSHA suggests conducting a worksite hazard assessment. OSHA provides guidelines in 29 CFR 1910 Subpart I Appendix B on methods to evaluate worksite hazards and methods to choose the proper PPE. After deciding on the proper PPE, employers must provide training to workers on the right use and maintenance of their PPE. Proper hazard assessment, PPE choice and training can significantly reduce worker injuries and assist to ensure a safe work environment.
