About Faceshield Protection

Faceshield protection is a crucial a 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 exposed 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 quite a few occasions.

The American National Standards Institute (ANSI) American National Normal for Occupational and Instructional Personal Eye and Face Protection Units customary Z87.1 was first revealed in 1968 and revised in 1979, 1989, 2003, 2010 and 2015. The 1989 model emphasized performance necessities to encourage and accommodate advancements in design, materials, applied sciences and product performance. The 2003 model added an enhanced consumer choice chart with a system for selecting equipment, akin to spectacles, goggles and faceshields that adequately protect from a specific hazard. The 2010 version focused on a hazard, similar to droplet and splash, impact, optical radiation, dust, fine dust and mist, and specifies the type of equipment needed to protect from that hazard. The 2015 revision continues to deal with product performance and harmonization with international standards. The 2015 standards fine-tune the 2010 hazard-based mostly product efficiency 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 intended to, when used together with spectacles and/or goggles, shield the wearer’s face, or parts thereof, in addition to the eyes from sure hazards, depending 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 whole machine—a product with all of its components in their configuration of meant use.

Though it will seem that from the faceshield definition change from 2010 to 2015 that faceshields assembly the efficiency standards of the 2015 customary can be used as standalone devices, all references in the modified Eye and Face Protection Choice Software discuss with "faceshields worn over goggles or spectacles."

Faceshield Selection
When deciding on faceshields, it is important to understand the importance of comfort, fit and ease of use. Faceshields should fit snugly and the first way to ensure a snug fit is through the headgear (suspension). Headgear is normally 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 optimal balance and the suspension should sit between half an inch and one inch above the eyebrows. Since faceshields are used at the side of different PPE, the interaction among the PPE needs to be seamless. Simple, easy-to-use faceshields that allow users to quickly adjust the fit are best.

Faceshield Visor Materials
Faceshield visors are constructed from a number of types of materials. These materials embrace polycarbonate, propionate, acetate, polyethylene terephthalate glycol (PETG) and steel or nylon mesh. It is important to choose 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 extraordinarily cold temperatures. Polycarbonate is generally more expensive than other visor materials.

Acetate provides the very best clarity of all the visor materials and tends to be more scratch resistant. It also gives chemical splash protection and could also be rated for impact protection.

Propionate material provides better impact protection than acetate while also offering chemical splash protection. Propionate materials tends to be a lower cost level than both acetate and polycarbonate.

Polyethylene terephthalate glycol (PETG) offers chemical splash protection and should provide impact protection. PETG tends to be essentially 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 business to assist protect the face from flying debris when slicing wood or shrubbery.

Specialty Faceshield Protection
Arc Flash – These faceshields are used for protection against 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 normal and should provide protection primarily based on an Arc Thermal Performance Value (ATPV), which is measured in energy per square centimeter (cal/cm2). The calorie rating must be decided first in an effort to choose the shield that will provide the most effective protection. Refer to Quick Tips 263 NFPA 70E: Electrical Safety Summary for more info on the proper selection of PPE.

Heat and Radiation – There are faceshields that provide protection towards heat and radiation. These faceshields stop burns by filtering out intense ultraviolet (UV) and infrared (IR) radiation. They are made from polycarbonate with special 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 often range from Shade 2 to14, with Shade 14 being the darkest shade. Check with Fast Tips 109: Welding Safety for more info on choosing the proper welding faceshields.

PPE Hazard Assessment, 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 the best way to consider worksite hazards and how to choose the proper PPE. After selecting 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 assist to ensure a safe work environment.
