WARNING
This face mask helps protect against certain particles. Misuse may result in sickness or death. For proper use see supervisor or instructions. Always Ensure proper fit.
Instruction For Use
Any use of the face mask requires full understanding and strict observation of the operating instructions. The face mask may only be used for the purposes specified here.
1. Open the bag. Take out the mask by hand and unfold it gently.
2. Bend the nose clip to the shape of your nose.
3. To fit the mask, stretch the two elastic bands carefully and secure them by hooking them behind the ears.
4. Adjust the mask so that it covers the nose and mouth, and place the nose clip on the nose bridge. Then adjust the mask so that the bottom of the mask is under your chin and the top part of the mask is secured at the top of the nose bridge. Make sure no air can pass through the outside edges of the mask. The efficiency of the mask and therefore your protection depend on the care taken when fitting the mask. With this in mind, you can adjust the fitting of the elastic bands for your personal comfort.
Conditions For Use:
1 – Before using this face mask, you must check that the mask corresponds to your needs in the specific environment of intended use. Failure to do so can put your health in danger, or even your life. Seek the advice of a professional (e.g. health and safety officer or doctor) to help you to define the protection you need.
2 – Failure to follow these instructions can harm your health, so please read them thoroughly and adhere to them.
3 – This mask does not produce oxygen, so it must be used in a sufficiently ventilated environment. If the oxygen content of the air around you falls below 17%, you will quickly feel dizzy, have difficulty breathing, or even faint. If this happens, you mustimmediately return to a well-ventilated place to avoid further complications.
4 – Do NOT use this mask if you don’t know the exact nature ofany toxin you may encounter. In particular, the mask must not be used near explosive products or in explosive atmospheres
5 – When fitting the mask, extra care should be taken by users who have facial hair or any facial irregularities. In these cases, take extra care to place the mask in such a way that no airways remain between the skin and the edges of the mask.
6 – Do NOT attempt to modify this mask: it has been designed and certified for your safety.
7 – This mask is intended for single use. After a maximum of 8 hours of continuous use, dispose of it. The mask will not regain its protective capacities after use.
8 – Keep the masks in an area with a maximum humidity level of 70%, and a temperature range of between -25°C and 40°C. The mask can lose its features and protective capacity after three years (see expiry date on the packaging), so it is risky to use this mask once the expiry date has passed. You are advised to dispose of any masks that have passed their expiry date.
9 – In any case and in spite of the whole care brought to this respiratory protective mask by the manufacturer, it is the user’s responsibility (and in no case the manufacturer’s responsibility) to ascertain the adequacy of the mask in relation to the environmental features where it will be stored and eventually be used. The manufacturer cannot guarantee a precise use length, considering its absence of knowledge of the environment in which the mask will have been stored since leaving the factory, and the features of the environment in which will be used (temperature, pressure, humidity, concentration of filtrable particles, user’s facial structure…)
10 – This mask will protect you only if you follow these recommendations, as well as the instructions for use. Failure to use the respirator in accordance with this manual will reduce the effectiveness of the product.
Fit Testing:
Overview of the Fit Testing Process
Tight-fitting respirators must seal to the wearer’s face in order to provide expected protection. This includes disposable respirators (also called “filtering facepieces”). Therefore, fit testing is required in the US by the Occupational Safety and Health Administration (OSHA) before a user wears a mandatory respirator on the job, and must be assessed at least annually. In addition, fit tests should be performed:
· Whenever a different size, style, model or make of respirator is used.
· When any facial changes occur that could affect fit, such as significant weight fluctuation or dental work.
OSHA doesn’t require fit test administrators to be certified, just to know how to conduct a test, recognize invalid tests, and properly clean and maintain equipment. Read more about OSHA fit testing protocols.
There are two kinds of tests: qualitative and quantitative.
Qualitative Fit Test (QLFT)
A qualitative fit test (QLFT) may only be used to fit-test:
· Negative-pressure, air-purifying respirators, as long as they’ll only be used in atmospheres where the hazard is at less than 10 times the permissible exposure limit (PEL).
· Tight fitting facepieces used with powered and atmosphere-supplying respirators.
QLFT is pass/fail and relies on the user’s senses using one of four OSHA-accepted test agents:
· Isoamyl acetate (banana smell); only for testing respirators with organic vapor cartridges.
· Saccharin (sweet taste); can test respirators with a particulate filter of any class.
· Bitrex® (bitter taste); can also test respirators with particulate filters of any class.
· Irritant smoke (involuntary cough reflex); only for testing respirators with level 100 particulate filters.
Each QLFT method uses seven exercises performed for 1 minute each:
· Normal breathing.
· Deep breathing.
· Moving head side to side.
· Moving head up and down.
· Bending over (or jogging in place if fit test unit doesn’t permit bending at the waist).
· Talking.
· Normal breathing again.
Quantitative Fit Test (QNFT)
A quantitative fit test (QNFT) can be used to fit-test any tight-fitting respirator. It involves using an instrument to measure leakage around the face seal and produces a numerical result called a “fit factor.” There are three OSHA-accepted QNFT test protocols:
· Generated aerosol uses a non-hazardous aerosol such as corn oil generated in a test chamber.
· Condensation nuclei counter (CNC) uses ambient aerosol and doesn’t require a test chamber.
· Controlled negative pressure (CNP) uses a test that creates a vacuum by temporarily cutting off air. (There is also a fourth method, which is an abbreviated version of this one.)
QNFTs use the same seven exercises as QLFTs, plus an additional “grimace” test where the subject smiles or frowns for 15 seconds.
A fit factor of at least 100 is required for half-mask respirators and a minimum fit factor of 500 for a full facepiece negative-pressure respirator.
