This type of respirator provides a higher level of protection than a half-facepiece respirator because it has better sealing characteristics. Since it covers the user's eyes and face, it can also be used to protect against liquid splashes and irritating vapors. Like the half-mask elastomeric respirator, this respirator is a tight-fitting, air-purifying respirator with replaceable filters or cartridges attached to a rubber or silicone facepiece.
It needs to be fit tested. This is a loose-fitting facepiece powered air-purifying respirator, or PAPR. A PAPR has a blower that pulls air through attached filters. The blower then pushes the filtered air into the facepiece, which covers all of the user's face. Since it is loose-fitting, it does not need to be fit tested and can be used by workers with facial hair. This PAPR has an elastomeric facepiece made of rubber or silicone.
It has filters and a blower that operate as they do on a loose-fitting facepiece PAPR. Because this PAPR has a tight-fitting facepiece, it must be fit tested. This is an airline respirator.
It supplies clean breathing air to either a hood or a facepiece through a long hose, from a source of clean air such as a cylinder or compressor. If the facepiece is tight-fitting, it must be fit tested. This is a self-contained breathing apparatus, or SCBA.
It is a type of atmosphere-supplying respirator. SCBAs have a tight-fitting, elastomeric facepiece that covers the user's face. The air is supplied from a cylinder of compressed breathing air that is designed to be carried by the respirator user. The facepiece is tight-fitting and must be fit tested. As its name implies, this respirator is truly self-contained. These respirators provide the highest level of respiratory protection.
You may hear someone refer to a respirator as an "N95" or a "P The filter material can be used in either a filtering facepiece respirator or in a filter cartridge that's attached to an elastomeric respirator. The first part of the filter's classification uses the letters N, R, or P to indicate the filter's ability to function when exposed to oils. This rating is only important in work settings where oils may be present, because some oils can reduce the effectiveness of the filter.
The second part of the classification -- the number-- refers to the filter's ability to remove the most-penetrating particle size during "worst case" testing. Filters that remove at least 95 percent of these particles are given a 95 rating. Those that filter out at least 99 percent receive a 99 rating, and those that filter out at least Using this classification method, an N95 filter is not resistant to oil and removes at least 95 percent of the most-penetrating particles.
When respiratory protection is required, employers must provide NIOSH-certified respirators to their workers. The logo and TC number can be found on the respirator's package or the user instruction insert, and sometimes they appear directly on respirator components, such as the respirator filter or cartridge.
You must never alter your respirator. Doing so can reduce its protective quality and expose you to the airborne hazard. Never glue or staple things to your respirator; do not write on your respirator's filter material; and never put holes in your respirator. This video has provided you with a brief overview of the types of respirators available and how they are selected to protect you against airborne workplace hazards.
You will find OSHA's Respiratory Protection Standard, additional respirator training videos, and other guidance material to help you work safely.
Este es un video sobre los distintos tipos de respiradores que los trabajadores pueden usar en sus lugares de trabajo. Por lo tanto, no se permite nada que interfiera con el sello del respirador cuando se usa este tipo de equipos. Debe realizar la prueba de ajuste antes de usar su respirador por primera vez.
Por lo tanto, no requieren pruebas de ajuste. Su empleador es responsable de seleccionar los respiradores adecuados para protegerlo de los peligros en el aire. Cada tipo de respirador tiene sus ventajas y desventajas, por lo tanto es importante que su empleador seleccione los que se ajusten mejor a su entorno de trabajo y los peligros a los que se expone. Requieren pruebas de ajuste, a menos que las condiciones de uso no sean obligatorias.
Requiere una prueba de ajuste. Como es de ajuste holgado, no necesita pruebas de ajuste y puede ser utilizado por trabajadores con vello facial. Puede escuchar a veces que la gente se refiere a los respiradores como un "N95" o un "P". N" significa No resistente al aceite; "R" significa relativamente Resistente al aceite; y "P" significa muy resistente al aceite, o a Prueba de aceite.
A veces aparecen directamente en los componentes del respirador, como el filtro o el cartucho. Nunca debe modificar su respirador. Nunca pegue o abroche cosas a su respirador; no escriba en el material filtrante de su respirador, y nunca agujeree su respirador. This video is about the respirator fit testing requirements for any worker who is required to use a tight-fitting respirator. While this video discusses some of your employer's responsibilities under OSHA's respiratory protection fit testing requirements, it is important to remember that using a respirator that fits you properly protects your health and safety.
A respirator can't protect you if it doesn't fit your face. It's that simple. Certain respirators, known as tight-fitting respirators, must form a tight seal with your face or neck to work properly. If your respirator doesn't fit your face properly, contaminated air can leak into your respirator facepiece, and you could breathe in hazardous substances. So before you wear a tight-fitting respirator at work, your employer must be sure that your respirator fits you.
Your employer does this by performing a fit test on you while you wear the same make, model, and size of respirator that you will be using on the job. That way, you know that your respirator fits you properly and can protect you, as long as you use it correctly. In addition, before you use a respirator or are fit-tested, your employer must ensure that you are medically able to wear it.
So what is a fit test? It takes about fifteen to twenty minutes to complete and is performed at least annually.
After passing a fit test with a respirator, you must use the exact same make, model, style, and size respirator on the job. Qualitative fit testing does not measure the actual amount of leakage.
Whether the respirator passes or fails the test is based simply on you detecting leakage of the test substance into your facepiece. There are four qualitative fit test methods accepted by OSHA:. Qualitative fit testing is normally used for half-mask respirators - those that just cover your mouth and nose. Half-mask respirators can be filtering facepiece respirators - often called "N95s" - as well as elastomeric respirators.
Quantitative fit testing uses a machine to measure the actual amount of leakage into the facepiece and does not rely upon your sense of taste, smell, or irritation in order to detect leakage.
The respirators used during this type of fit testing will have a probe attached to the facepiece that will be connected to the machine by a hose. There are three quantitative fit test methods accepted by OSHA:. Many workers need to wear prescription glasses or personal protective equipment, such as safety goggles or earmuffs, while performing a job.
If you fall into this category, then you must wear these items during the fit test to be sure they don't interfere with the respirator's fit. You must be fit tested before you use a respirator in the workplace, and you must be retested at least every 12 months to make sure that the respirator you use still fits you.
You must be fit tested with the specific make, model, style, and size of respirator that you will be using. Not everyone can get a good fit with one specific respirator. If the respirator fails the fit test, then another make, model, style, or size must be tried until one is found that fits you properly. Therefore, your employer needs to provide you with a reasonable selection of sizes and models to choose from. When you've completed the fit testing process, it's very important that you know which make, model, style, and size respirator fits your face properly, and when and where you'll need to wear it for protection.
Also, the fit of your respirator must be retested whenever you have a change in your physical condition that could affect the fit of you respirator. Such changes could include:. Any of these changes could affect the ability of your respirator to properly seal to your face, which could allow contaminated air to leak into your respirator facepiece. If you find that the fit of your respirator becomes unacceptable, you must be allowed to select a different type of respirator and be retested.
The selection may include a new make, model, style, or size of respirator. Facial hair, like a beard or mustache, can affect your respirator's ability to protect you. Anything that comes between your face and the respirator's seal or gets into the respirator's valves can allow contaminated air to leak into the respirator facepiece and you will not be protected.
For example, if you have long hair, make sure it doesn't get between the respirator seal and your face because this can allow contaminated air to leak into the respirator.
Fit testing can be done by your employer or an outside party, including a union, an apprenticeship program, a contractor's association, or a past employer. Your current employer is permitted to accept fit testing you have received from an outside party such as a former employer within the last 12 months, as long as you use the same respirator make, model, style, and size at your new worksite. This is known as "fit testing portability.
While recent fit testing can follow you from job to job, it is still your current employer's responsibility to ensure that the fit testing and recordkeeping requirements of OSHA's respiratory protection standard have been met before you use a respirator for protection against hazardous exposures at work.
Sometimes workers own their own respirators and bring them to a job where respiratory protection is required.
If your employer allows you to use your own personal respirator for protection, then your employer still has to comply with all of the requirements of the OSHA standard.
For example, your employer must still ensure that:. Keep in mind, however, that while your employer may allow you to use your own respirator, your employer cannot require you to use your own respirator.
This video has provided you with a brief overview of OSHA's fit testing requirements. Un respirador no puede protegerlo si no se ajusta a su cara. Esos cambios pueden incluir:. Esto se conoce como "transferibilidad de las pruebas de ajuste". Recuerde, sin embargo, que aunque su empleador puede autorizarlo a usar su propio respirador, no puede obligarlo a usar su propio respirador.
Este video le ha proporcionado un breve resumen de los requisitos para las pruebas de ajuste de la OSHA. This is a video about respirator maintenance and care requirements for any worker who wears a respirator. The federal Occupational Safety and Health Administration - also called "OSHA" - and State OSHA Agencies require employers to have a respiratory protection program that includes provisions for the cleaning, disinfecting, inspection, repair, and storage of respirators used by workers on the job.
While this video discusses some of your employer's responsibilities under OSHA's Respiratory Protection Standard, it is important to remember that your respirator must be properly maintained so that it can protect you. Respirators are not maintenance-free. The program must provide for the cleaning, disinfecting, inspection, repair, and storage of each type of respirator used in your workplace.
This includes respirators used in emergency situations, for emergency escape, and self-contained breathing apparatuses. In addition, the National Institute for Occupational Safety and Health - also called NIOSH - requires each respirator manufacturer to include a section in their user instructions that provides the recommended practices for maintenance and care of the respirator.
Your employer must ensure that the respirator you use is clean, sanitary, and in good working order. Cleaning and disinfecting must be done using either the procedures in OSHA's Respiratory Protection Standard or the procedures recommended by the respirator manufacturer, provided they are at least as effective as OSHA's. The manufacturer's procedures should always be checked to see if certain cleaners or disinfectants might damage the respirator and should not be used.
If this is the case, the manufacturer's instructions must be followed. In general, cleaning and disinfecting consists of taking the respirator apart, washing it, disinfecting it, thoroughly rinsing it, and putting it back together when it is dry. Respirators must be cleaned as often as necessary to prevent them from becoming unsanitary. In addition, respirators worn by more than one user must be cleaned and disinfected before being worn by a different user, and emergency use respirators must be cleaned and disinfected after each use.
While filtering facepiece respirators cannot be cleaned or disinfected, it is still important that you inspect them for cleanliness and damage before each use. All respirators must be inspected for basic function before each use and during the cleaning and disinfecting process.
A respirator inspection must include a check of the respirator's ability to work properly; the tightness of any connections; and the condition of the various parts, such as the facepiece, head straps, valves, tubes, hoses, and any cartridges, canisters, or filters.
In addition, elastomeric parts must be checked for pliability and signs of deterioration. Regular care and maintenance of the respirator is important to be sure that it works properly. If your respirator fails an inspection or is defective, your employer must remove it from service and either repair it or discard it.
Repairs or adjustments must be made only by appropriately trained people. In addition, repairs must be made according to the respirator manufacturer's instructions and must use only NIOSH-approved parts that are designed for the respirator. It is important for respirators to be stored properly to protect them from damage, contamination, dust, sunlight, extreme temperatures, excessive moisture, and damaging chemicals.
Never leave your respirator hanging on a machine, lying on your workbench, or tossed into your toolbox or a drawer. Always store your respirator in a way that prevents deforming the facepiece or exhalation valve.
Avoid carrying a cup-shaped filtering facepiece respirator in your pocket or toolbox. This could crush it and cause the facepiece to be bent out of shape, preventing the respirator from sealing tightly to your face and properly protecting you. Air-purifying respirators use a filter or cartridge to remove hazards from the air you breathe. A properly functioning air-purifying respirator can provide effective protection for as long as the filters or cartridges work correctly.
For respirators that use filters to clean the air, the filters must be replaced whenever they are damaged, soiled, or cause noticeably increased breathing resistance. Before each use, the outside of the filter material must be inspected. If the filter material is physically damaged or soiled, the filter must be replaced or, in the case of a filtering facepiece respirator, the respirator must be discarded.
Filtering facepiece respirators can be reused by the same worker, but only if the respirator is working properly, its shape remains unchanged, and the filter material is not physically damaged or soiled. Of course, there may be reasons for disposing of a filtering facepiece respirator that still appears to be functional. Your employer must identify the circumstances in which a filtering facepiece respirator will be considered to be contaminated, unsanitary, or otherwise not able to be reused so that you can recognize when a new respirator is needed.
Some gas and vapor hazards require the use of respirator cartridges or canisters containing materials that absorb or remove these hazards from the air. However, cartridges or canisters can only absorb a limited amount of hazardous gas or vapor. To ensure your protection, they must be replaced before they reach this limit.
If you use a respirator for protection against gases and vapors, your employer must determine a schedule for replacing worn out cartridges or canisters. This is known as a "change-out schedule. Remember, never rely on your ability to smell a contaminant to warn you of cartridge or canister failure. If you do smell a contaminant while wearing your respirator, leave the area and notify your supervisor immediately. This video has provided you with a brief overview of OSHA's respirator maintenance and care requirements.
Este es un video sobre el mantenimiento y el cuidado de los equipos para los trabajadores que usan respiradores. Los respiradores necesitan mantenimiento. Los respiradores se deben limpiar tan a menudo como sea necesario para evitar problemas de salubridad. El cuidado y mantenimiento regular del respirador es importante para garantizar que funcione adecuadamente. Las reparaciones y ajustes solo deben ser realizados por personas adecuadamente capacitadas.
Los respiradores purificadores de aire usan un filtro o cartuchos para eliminar los peligros del aire que usted respira. Un respirador purificador de aire que funciona correctamente puede protegerlo de manera eficaz siempre que los filtros o cartuchos funcionen adecuadamente. Antes de cada uso debe inspeccionarse la parte exterior del material del filtro.
Algunos peligros de gases y vapores exigen el uso de respiradores con cartuchos, que contienen materiales que absorben o eliminan esos peligros del aire. Pro-Fit Phnom Penh personal trainers train you at your apartment gym, in-home, hotel or park in Phnom Penh.

Choose respirators certified for use to protect against the contaminant of concern. Department of Health and Human Services, certifies respirators. A label or statement of certification should appear on the respirator or respirator packaging.
It will tell you what the respirator is designed for and how much it will protect you. Do not wear your respirator into atmospheres containing contaminants for which your respirator is not designed to protect against. For example, a respirator designed to filter dust particles will not protect you against gases, vapors, or very small solid particles of fumes or smoke. Keep track of your respirator so that you do not mistakenly use someone else's respirator.
The employer shall include in the program the following provisions of this section, as applicable: vii - Training of employees in the respiratory hazards to which they are potentially exposed during routine and emergency situations; viii - Training of employees in the proper use of respirators, including putting on and removing them, any limitations on their use, and their maintenance; 2 - Where respirator use is not required: i - An employer may provide respirators at the request of employees or permit employees to use their own respirators, if the employer determines that such respirator use will not in itself create a hazard.
For all IDLH atmospheres, the employer shall ensure that: iii - The employee s located outside the IDLH atmosphere are trained and equipped to provide effective emergency rescue; h — Maintenance and Care of Respirators 4 — Repairs i - Repairs or adjustments to respirators are to be made only by persons appropriately trained to perform such operations and shall use only the respirator manufacturer's NIOSH-approved parts designed for the respirator; iii - Reducing and admission valves, regulators, and alarms shall be adjusted or repaired only by the manufacturer or a technician trained by the manufacturer.
