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 using 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 potentially injurious light radiation.
The original 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 normal Z87.1 was first revealed in 1968 and revised in 1979, 1989, 2003, 2010 and 2015. The 1989 model emphasized performance requirements to encourage and accommodate advancements in design, materials, applied sciences and product performance. The 2003 version added an enhanced consumer selection chart with a system for selecting equipment, corresponding to spectacles, goggles and faceshields that adequately protect from a selected hazard. The 2010 version focused on a hazard, corresponding 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 international standards. The 2015 standards fine-tune the 2010 hazard-primarily based product performance structure.
The majority of eye and face protection in use in the present day 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 side 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 intended 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 components in their configuration of supposed use.
Though it could seem that from the faceshield definition change from 2010 to 2015 that faceshields assembly the performance standards of the 2015 commonplace can be utilized as standalone devices, all references in the modified Eye and Face Protection Selection Instrument consult with “faceshields worn over goggles or spectacles.”
Faceshield Choice
When choosing faceshields, it is very important understand the importance of comfort, fit and ease of use. Faceshields should fit snugly and the primary way to ensure a cosy fit is thru 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 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 other PPE, the interaction among the many PPE must be seamless. Simple, easy-to-use faceshields that enable users to quickly adjust the fit are best.
Faceshield Visor Materials
Faceshield visors are constructed from several types of materials. These supplies embrace polycarbonate, propionate, acetate, polyethylene terephthalate glycol (PETG) and metal or nylon mesh. You will need to select the proper visor for the work environment.
Polycarbonate materials provides one of the best impact and heat resistance of all visor materials. Polycarbonate additionally provides chemical splash protection and holds up well in extremely cold temperatures. Polycarbonate is generally more expensive than other visor materials.
Acetate provides the most effective clarity of all the visor materials and tends to be more scratch resistant. It additionally gives chemical splash protection and could also be rated for impact protection.
Propionate material provides higher impact protection than acetate while also providing chemical splash protection. Propionate materials tends to be a cheaper price level than both acetate and polycarbonate.
Polyethylene terephthalate glycol (PETG) gives 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 within the logging and landscaping industry to help protect the face from flying particles when slicing 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 in the National Fire Protection Affiliation (NFPA) 70E standard. Faceshields are included in this customary and must provide protection primarily based on an Arc Thermal Efficiency Worth (ATPV), which is measured in calories per sq. centimeter (cal/cm2). The calorie ranking must be decided first with a purpose to select the shield that will provide the perfect protection. Consult with Quick Suggestions 263 NFPA 70E: Electrical Safety Abstract for more information on the proper choice of PPE.
Heat and Radiation – There are faceshields that provide protection against heat and radiation. These faceshields stop burns by filtering out intense ultraviolet (UV) and infrared (IR) radiation. They are made from polycarbonate with particular 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. Confer with Fast Tips 109: Welding Safety for more information on selecting the proper welding faceshields.
PPE Hazard Assessment, Choice and Training
When choosing 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 best way to evaluate worksite hazards and how to choose the proper PPE. After deciding on the proper PPE, employers should provide training to workers on the correct use and maintenance of their PPE. Proper hazard assessment, PPE selection and training can significantly reduce worker injuries and help to ensure a safe work environment.
