Faceshield protection is a vital a part of personal protective equipment (PPE). Employers are recognizing the added protection that faceshields provide and usage 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 exposed to eye or face hazards similar to flying objects, molten metal, liquid chemical substances, acids or caustic liquids, chemical gases or vapors, or potentially injurious light radiation.
The unique OSHA standards addressing eye and face protection have 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 Commonplace for Occupational and Instructional Personal Eye and Face Protection Gadgets standard Z87.1 was first published in 1968 and revised in 1979, 1989, 2003, 2010 and 2015. The 1989 model emphasized performance requirements to encourage and accommodate advancements in design, supplies, technologies and product performance. The 2003 model added an enhanced person choice chart with a system for selecting equipment, akin to spectacles, goggles and faceshields that adequately protect from a particular hazard. The 2010 version centered on a hazard, equivalent to droplet and splash, impact, optical radiation, mud, fine mud and mist, and specifies the type of equipment needed to protect from that hazard. The 2015 revision continues to give attention to product performance and harmonization with international standards. The 2015 standards fine-tune the 2010 hazard-based product efficiency structure.
The majority of eye and face protection in use at the moment 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 parts 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 portions thereof from sure hazards, as indicated by the faceshield’s markings.” A protector is an entire gadget—a product with all of its components of their configuration of intended use.
Although it might seem that from the faceshield definition change from 2010 to 2015 that faceshields meeting the performance criteria of the 2015 normal can be used as standalone gadgets, all references in the modified Eye and Face Protection Choice Software discuss with “faceshields worn over goggles or spectacles.”
Faceshield Selection
When selecting faceshields, you will need to 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 highest band is adjusted for depth. When worn properly, the faceshield should be centered for optimum balance and the suspension ought to sit between half an inch and one inch above the eyebrows. Since faceshields are used along with other PPE, the interplay among the PPE must be seamless. Simple, straightforward-to-use faceshields that enable users to shortly adjust the fit are best.
Faceshield Visor Materials
Faceshield visors are constructed from a number of types of materials. These supplies embrace 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 additionally provides chemical splash protection and holds up well in extraordinarily cold temperatures. Polycarbonate is mostly more costly than other visor materials.
Acetate provides one of the best clarity of all the visor supplies and tends to be more scratch resistant. It additionally affords chemical splash protection and may be rated for impact protection.
Propionate material provides better impact protection than acetate while additionally offering chemical splash protection. Propionate materials tends to be a cheaper price level than each acetate and polycarbonate.
Polyethylene terephthalate glycol (PETG) presents chemical splash protection and may provide impact protection. PETG tends to be essentially 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 help protect the face from flying particles when slicing wood or shrubbery.
Specialty Faceshield Protection
Arc Flash – These faceshields are used for protection in opposition to an arc flash. The necessities for arc flash protection are given in the National Fire Protection Association (NFPA) 70E standard. Faceshields are included in this commonplace and must provide protection primarily based on an Arc Thermal Performance Worth (ATPV), which is measured in energy per square centimeter (cal/cm2). The calorie score must be determined first in an effort to choose the shield that will provide the most effective protection. Refer to Fast Tips 263 NFPA 70E: Electrical Safety Summary for more data on the proper number of PPE.
Heat and Radiation – There are faceshields that provide protection in opposition to heat and radiation. These faceshields stop burns by filtering out intense ultraviolet (UV) and infrared (IR) radiation. They’re made from polycarbonate with particular coatings. An instance of this could be adding a thin layer of gold film to increase reflectivity.
Welding – Shaded welding faceshields provide protection from UV and IR radiation generated when working with molten metal. The shades usually range from Shade 2 to14, with Shade 14 being the darkest shade. Check with Quick Suggestions 109: Welding Safety for more info on deciding on the proper welding faceshields.
PPE Hazard Evaluation, Selection and Training
When deciding on 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 methods to consider worksite hazards and tips on how to select the proper PPE. After selecting the proper PPE, employers must provide training to workers on the correct use and upkeep of their PPE. Proper hazard assessment, PPE selection and training can significantly reduce worker injuries and help to ensure a safe work environment.
