Faceshield protection is a vital 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 equivalent to flying objects, molten metal, liquid chemical substances, acids or caustic liquids, chemical gases or vapors, or doubtlessly 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 Normal for Occupational and Educational Personal Eye and Face Protection Units commonplace Z87.1 was first printed in 1968 and revised in 1979, 1989, 2003, 2010 and 2015. The 1989 model emphasised efficiency requirements to encourage and accommodate advancements in design, supplies, technologies and product performance. The 2003 version added an enhanced consumer selection chart with a system for selecting equipment, equivalent to spectacles, goggles and faceshields that adequately protect from a specific hazard. The 2010 model centered 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 concentrate on product performance and harmonization with world standards. The 2015 standards fine-tune the 2010 hazard-based mostly product efficiency structure.
The majority of eye and face protection in use at present 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 together with spectacles and/or goggles, shield the wearer’s face, or parts thereof, in addition to the eyes from certain hazards, relying 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 supposed use.
Though it will seem that from the faceshield definition change from 2010 to 2015 that faceshields assembly the efficiency criteria of the 2015 normal can be used as standalone devices, all references in the modified Eye and Face Protection Choice Instrument confer with “faceshields worn over goggles or spectacles.”
Faceshield Choice
When choosing faceshields, you will need to understand the importance of comfort, fit and ease of use. Faceshields should fit snugly and the first way to ensure a comfortable fit is through the headgear (suspension). Headgear is usually 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 needs 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 in conjunction with other PPE, the interplay among the PPE needs to be seamless. Simple, simple-to-use faceshields that permit 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 very important select the proper visor for the work environment.
Polycarbonate material provides the 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 usually more expensive than other visor materials.
Acetate provides the most effective clarity of all of the visor materials 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 also providing chemical splash protection. Propionate materials tends to be a lower price point than both acetate and polycarbonate.
Polyethylene terephthalate glycol (PETG) affords chemical splash protection and should provide impact protection. PETG tends to be probably 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 help 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 necessities for arc flash protection are given within the National Fire Protection Association (NFPA) 70E standard. Faceshields are included in this commonplace and should provide protection based mostly on an Arc Thermal Efficiency Value (ATPV), which is measured in energy per sq. centimeter (cal/cm2). The calorie ranking have to be determined first so as to select the shield that may provide the most effective protection. Check with Fast Tips 263 NFPA 70E: Electrical Safety Abstract for more info on the proper selection of PPE.
Heat and Radiation – There are faceshields that provide protection in opposition to 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 instance of this can 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 often range from Shade 2 to14, with Shade 14 being the darkest shade. Refer to Quick Tips 109: Welding Safety for more info on selecting the proper welding faceshields.
PPE Hazard Evaluation, Choice 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 methods to evaluate worksite hazards and how one can select the proper PPE. After deciding on the proper PPE, employers must provide training to workers on the proper use and maintenance of their PPE. Proper hazard evaluation, PPE selection and training can significantly reduce worker accidents and help to ensure a safe work environment.
