![]() ![]() The air intake, which pulls outdoor air inside, should not be placed near the building exhaust. If the makeup air is too weak, there will be negative pressure areas and perhaps drafts. Provide enough makeup air to replace the exhausted air. The fan supplier may be able to install your fan, as well as supply the duct work and other needed materials. You can find a fan supplier by looking in a directory called “Thomas Register of American Manufacturers.” Look under the headings of “fans” or “fans, centrifugal.” Your public library should have this directory. Use either a multi-speed or high-volume exhaust fan with a damper. To prevent fan noise from getting in the way of talk or client comfort, you can do one of three things: (1) buy a quiet fan, (2) put a cover over a noisier fan, or (3) buy an outdoor fan to be placed on an outside wall. A 1/8 horse power centrifugal fan should work well. Although a stronger and larger airflow will collect more dust during filing and dry the color coat faster, a slower and lower airflow gives better results for the artificial fingernail product.Ĭhoose an exhaust fan that can exhaust at least 250 cubic feet per minute of air and has 1/4-inch static pressure. A 22-inch baffle should surround the downdraft face to pull the moving air closer to the client=s hands.ĭifferent drying times are needed for different fingernail products and different application techniques. However, too much air rushing past the fingernails may cause the artificial nail product to crystallize.Īn air speed of 620 feet per minute, directly above the 13- by 4-inch downdraft face works well. The amount of air exhausted depends on its speed as it moves through the downdraft face and on the size of the table opening. Make sure enough air blows through the table downdraft to get rid of the EMA. This will allow the client’s hands to hang over the downdraft face and be as close as possible to the local exhaust ventilation (Figure 2). ![]() The client’s side of the table should be a little higher than the technician’s side. Cover the hole with a screen-like cover (or perforated plate) to prevent things from falling in. This downdraft face should be placed on the technician’s side of the table. Make a hole in the table top for an air intake (called the downdraft face). A veneer-coated particle board works well for the table material. If the table acts like a sponge, it may actually expose you to the chemicals you want to avoid. Choose a wood for your ventilated table that will not soak up the chemicals. Ventilated table sizes will vary from nail salon to nail salon. Charcoal filters that allow the air to be used over again are not recommended because it is hard to know when the charcoal is full.īuild a ventilated table, or change a table you already own into a ventilated one (Figure 1). Place local exhaust ventilation as close to the EMA source as possible. ![]() The ventilated table is the most important engineering control for getting rid of EMA in the fingernail salon because the vented table places local exhaust ventilation close to the work area. Researchers from the National Institute for Occupational Safety and Health (NIOSH) have found that a ventilation table protects the nail technician best against breathing EMA. Finally, you should look at your work habits to see if they can be improved. It is also helpful to keep all bottles of fingernail liquid tightly capped. In the nail salon, to get rid of EMA in the air you breathe, you should apply artificial fingernails at a ventilated work table. ![]() Because it is often difficult to tell which chemical in a nail salon is causing a sensitivity or allergy, it is best to control your exposure before you become sensitized. Both can make the eyes, nose, and other mucous membranes sting, become red, and swell. However, both MMA and EMA can cause contact dermatitis, asthma, and allergies in the eyes and nose, all problems that nail technicians know about. MMA was proven harmful to nail technicians and customers. Food and Drug Administration outlawed a similar chemical, methyl methacrylate (MMA), used in fingernail products. Artificial fingernail products are made from many chemicals, but the main one in most of these products is ethyl methacrylate (EMA). ![]()
