As with other forms of PPE, high-visibility safety apparel (HVSA) aims to protect workers by providing conspicuity (clear/prominent visibility) in a variety of work environments, reducing the risk of worker injury or fatality. For workers exposed to moving vehicles, construction equipment, and/or low-light conditions where visibility is a concern, proper HVSA improves workers’ safety by effectively mitigating the struck-by hazards inherent to these work environments.
High-visibility safety apparel may consist of three parts: background material, retroreflective material, and combined-performance material. The background material is highly conspicuous and fluorescent in color; the retroreflective material reflects light back to the source when light shines on the material; while combined-performance material is a combination of retroreflective and fluorescent material that can be counted toward the minimum area requirements for background material.
The American National Standard for High-Visibility Safety Apparel and Accessories (ANSI/ISEA 107-2015) establishes 4 Performance Classes of HVSA: Performance Class 1, Performance Class 2, Performance Class 3, and Performance Class E. A garment’s Performance Class is contingent upon both its design attributes and the amount of high-visibility materials incorporated, with Performance Class 1 requiring the least amount of high-visibility materials (thus providing the lowest level of conspicuity) and Performance Class 3 requiring the most amount of high-visibility materials (through a full range of movement), thus offering the highest level of worker visibility.
In addition to Performance Classes, there are 3 Types of HVSA that allude to the exposure risk of certain work activities/environments, as well the corresponding protection level required. Types of HVSA include: Type O (Off-road), Type R (Roadway), and Type P (Public Safety). It is important to note that types and classes are co-dependent, meaning high-visibility apparel is designated with both a Type and Performance Class. Specifically, Performance Class 1 apparel is explicitly Type O. Performance Class 2 apparel may be either Type R or Type P, and Performance Class 3 apparel may also be either Type R or Type P.
As referenced, Performance Class 1 apparel provides the minimal amount of required material to differentiate the worker from his or her non-complex, off-road work environment. For a garment to qualify as Performance Class 1, it must be fluorescent lime, fluorescent orange, or fluorescent red in color, while also featuring at least 155 square inches of retroreflective or combined-performance material.
Performance Class 2 apparel provides additional coverage in the context of visibility when compared to Performance Class 1 apparel. This class of apparel is considered the minimum level of protection for workers exposed to traffic from public access highway rights-of-way or roadway temporary traffic control zones.
Enhanced with additional high-visibility materials beyond Class 2, Performance Class 3 apparel offers the highest conspicuity through a full range of movement and is to be worn in complex work environments posing the highest risks to worker safety, such as working at night, on or near roadway traffic, without a physical barrier, or in highly congested areas. A primary distinction between Performance Class 2 and 3 apparel is that Performance Class 3 vests/shirts must have either long or short sleeves. However, one may pair a Class 2 [sleeveless] safety vest with Class E (see below) shorts or trousers to achieve the overall classification of a Performance Class 3 ensemble.
Performance Class E includes pants, bibs, overalls, shorts, and gaiters that, worn alone, do not qualify as meeting the requirements of other Performance Classes; however, when worn in conjunction with a Performance Class 2 or 3 garment, collectively comprise a Performance Class 3 ensemble.
Type O HVSA is for workers in off-road occupational environments which pose struck-by hazards from moving vehicles, equipment, or machinery, but does not include exposure to traffic from public access highway rights-of-way or roadway temporary traffic control zones. Examples of occupational activities for Type O HVSA may include:
Type R HVSA is federally mandated high-visibility PPE for workers in occupational environments which include exposure to traffic from public access highway rights-of-way or roadway temporary control zones. Examples of occupational activities for Type R HVSA include:
Type P HVSA offers additional options to fire, police, and EMS personnel who are exposed to struck-by hazards in roadway or off-road work environments and have other potential hazards that may require access to special equipment. Along with fire, police, and EMS personnel, other examples of occupational activities for Type P HVSA may include:

Nursing Homes: Failure to sterilize linens can become an incubator for the spread of Bacteria and may cause infections in residents, personnel who work at the facility and family and friends who come to visit.
Nursing homes, other health care and extended living operations can produce 2,500 lbs. of dirty laundry a day. Sheets with blood, urine, feces and other bodily fluids are routinely washed with other, less contaminated items.
To ensure laundry is clean and sanitized key steps are necessary in the processing of Linens. Housekeeping and laundry personnel need to wear gloves, goggles and any other types of protective equipment and clothing. Coveralls made of TYVEK will give you the flexibility and durability you require to perform all your functions while being protected. This step is vital when handling, transporting, sorting and washing soiled linens. When collecting and transporting soiled linen, handle it as little as possible and with minimum contact to avoid accidental injury and the spread of microorganisms. Carry linens in covered containers or plastic bags to prevent spills and splashes and confine the soiled linen to a designated area.
|Recommended Personal Protective Equipment for Processing LinenTYPE OF PPE WHEN TO WEAR
Gloves and closed shoes that protect feet from dropped items and spilled blood and body fluids, Goggles and protective TYVEK Coverall are all suggested to be added to your cleaning wardrobe. You should protect yourself when you are involved in the following cleaning steps.
Do not do any sorting or washing of soiled linens in areas where patients live or come in contact with. Establish an area that has adequate ventilation and physical barriers (walls) between the clean and soiled linen areas. Safe sorting is extremely important. Bedding from patient’s rooms may contain blood –stained or wet with other body fluids. Washing and drying all linen items used in the direct care of a resident must be thoroughly washed before reuse. Decontamination prior to washing is not necessary, unless linen is heavily soiled. Using Amerisource ONYX, our break detergent will help you handle the most difficult soiled linens. You can also add bleach about 2 to 3 table spoons will do it, using our OPAL De-Strainer and Sanitizer.
Remember throughout this process make sure if at any time you take your gloves off make sure you wash your hands.
When the linens are clean they are ready to be stored in a clean storage area, keep shelves clean and handle the stored linen as little as possible. During transportation back to the resident the linens should be wrapped or covered to avoid any contamination. Do not leave extra linen in a room, avoid shaking linen as it may release dust and lint into the room also clean soiled mattresses before putting linen on them.
It is important that care be taken when you are handling the needs and heath of the elderly. All of us some day will depend on someone else to maintain a clean environment for us.
Hazardous & Non-Hazardous Protective Apparel
There are a number of types of outer clothing including non-hazardous apparel (for use in oil, dirt and grime where the wearer does not want to get clothes soiled), and hazardous apparel, including toxic waste, fire retardant and chemical apparel.
The non-hazardous apparel is usually called “Limited Use and/or Disposable.” This type of clothing comes in a variety of styles. The wearer can have items by the piece; pants, jacket, sleeves, boots, apron, hood and full face hood and shield or he can wear One-Piece Coveralls that can come with elastic wrist/ankle bands for a tighter fit. The coveralls can come with boots, hoods and complete hood w/face shield.
Lakeland makes their disposable garments from two types of material, MicroMAX, which is general purpose protective material that can be used in any non-hazardous environment. MicroMAX is comprised of a microporous film with a nylon scrim between the film and the sub-strate, this gives the material added strength. The other material is “Tyvek”.
There are different types of MicroMAX clothing signified by the type of use, seam joints and composition. They are HBF, NS and NS Cool Suit.
HBF utilizes the fabric structure to limit challenge material penetration through the fabric. The same fabric structure, when combined with the physical properties of the melt-blown layer, promotes the exchange of air and moisture between the inside of the fabric and the exterior. The result is outstanding barrier and comfort. NS features high MVTR’s and is breathable for worker comfort. MicroMAX® NS is strong, wet or dry. NS Cool Suit is made with the same material with an added spunbond polypropylene back panel. This give the suit added breathability.
The different types of stitching used in the clothing are Serged Seams, Sewn and Bound Seams and Heat Sealed Seams. A serged seam joins two pieces of material with a thread that interlocks. This is an economical stitching method for general applications. It is more commonly found on limited use clothing where dry particles are of a concern.
A sewn and bound seam joins two pieces of material with an overlay of similar material and is chain stitched through all of the layers for a clean finished edge. This provides increased holdout of liquids and dry particulates.
A heat sealed seam is sewn and then sealed with a heat activated tape. This method provides liquid proof seams, and is especially useful for Level A and B chemical protective clothing.
The basic OSHA Standard calls for 4 levels of protection, A – D and it also specifies in detail the equipment and clothing required to protect the wearer. Lakeland makes Level A and Level B apparel.
Level A represents the greatest danger to respiratory, eye and/or skin damage from hazardous vapors, gases, particulates, sudden splash, immersion or contact with haz-mat. It calls for total Encapsulation in a vapor tight chemical suit with self contained breathing apparatus (SCBA) or supplied air.
Level B situations calls for the highest degree of respiratory protection but a lesser degree of skin protection. It calls for SCBA or positive pressure supplied air with escape SCBA. Level B suits can be fully encapsulated or pieced together in various garments.
