Q16：What is the shelf life of 3M’s filtering facepiece respirators?
问16：3M随弃式呼吸防护口罩的存放期是多长时间？
A：In the U.S. there is currently no regulatory requirement for manufacturers of respiratory protection devices to include storage or shelf life information. In their Respiratory Protection standard, 29 CFR 1910.134, OSHA does require that respirators be stored to protect them from damage, contamination, dust, sunlight, extreme temperatures, excessive moisture, and damaging chemicals, and that they be stored to prevent deformation of the facepiece and exhalation valve. OSHA also requires respirators be stored in accordance with any applicable manufacturer instructions and that the wearer inspect the product prior to use. If a user finds a respirator that has damage to a component they should discard it and get a different respirator of the same model.
答：在美国，目前的法规中并没有要求制造商必须提供呼吸器有效存放期的信息。在OSHA 的呼吸保护标准29CFR1910.134中，规定呼吸器应储存在安全、无污染、无尘、无日光照射、无极端温度、无高湿、无有害化学物的环境中，储存中应防止呼吸器面罩和呼气阀的变形。OSHA还要求，应按照制造商的使用说明条件储存呼吸器，使用者在使用前应检查呼吸器，确保完好。如果使用者发现呼吸器部件已经损坏，应将其废弃，应更换一个相同型号的新的呼吸器。
Although there is currently no shelf life stated on most 3M NIOSH approved filtering facepiece respirators, respirator shelf life will benefit from controlled storage conditions. 3M recommends filtering facepiece respirators be stored in their original packaging within climatic conditions ranging from -4°F (-20°C) to +86°F (+30°C)and not exceeding 80% RH.. Always inspect product and conduct a user seal check before use as specified in the User Instructions. Examine all the respirator parts for signs of damage including the headbands, nose foam and staples, If a user finds a respirator that has damage to a component they should discard it and get a different respirator of the same model. If you cannot achieve a proper seal, do not use the respirator.
尽管3M获得NIOSH认证的绝大多数随弃式呼吸器目前都没有提供有效存放期，但对存放条件的控制，会有益于呼吸器的有效存放。3M建议，将随弃式呼吸器存放在原包装中，存放温度不超过-20°C (-4°F)至 +30°C (+86°F)的范围，湿度不超过80%RH。使用之前务必对呼吸器进行检查，并按照使用说明进行佩戴气密性检查。检查呼吸器应包括对所有部件的检查，即头带、鼻垫和钉子。如果使用者发现呼吸器部件已经损坏，应将其废弃，应更换一个相同型号的新的呼吸器。如果您无法取得正确的密合，请不要使用这个呼吸器。
Outside the United States shelf life ("use by" dates) and/or storage conditions are commonly required by country respirator certification standards. Such statements are found on many of the products manufactured to other requirements, including European standards (CE marked), where the end of shelf life and storage conditions (temperature and humidity) are required by the regulation to be communicated on the packaging. Typical use by dates for filtering facepiece respirators are in the three to five year range for product stored in the conditions specified on the packaging.
在美国以外的国家，呼吸器认证标准中通常要求呼吸器提供有效的存放期（在XX日期前使用），在按照其他国家的规定，包括按照欧洲标准（CE标记）制造的呼吸器的包装上，会提供有效存放期和存放条件（温度和湿度）。在包装上规定的存放条件下，随弃式呼吸防护口罩的有效存放期通常为制造之日起3至5年。
