Face Covering Policy
Updated March 14,2024
Grand Valley moved its COVID alert level to Level 0 这意味着在所有校园地点都不需要戴口罩, including classrooms and other academic spaces.
教师可以要求学生在课堂上戴口罩，但不能强制要求. 在某些特殊情况下仍可能需要戴口罩, such as those regulated by the government.
我们知道这将是对我们习惯的一个重大改变. 校园社区的一些成员将选择继续戴口罩, 他们应该得到所有湖人队员的支持. 教职员工可以要求在私人办公室佩戴口罩.
Grand Valley has obtained 10,000 KN95 masks and 10,000医疗程序(ASTM 1)口罩为希望佩戴这些校园社区成员. 各部门可通过正常的PPE申领流程订购这些口罩 Facilities Services. More masks are on order and expected soon. 尽管面临供应链压力，我们仍将尽一切可能确保口罩供应充足.
学生可以在以下地点领取这些类型的口罩. Supplies will be replenished each weekday.
Allendale Campus: 娱乐中心，玛丽·艾德玛·皮尤图书馆，柯克霍夫中心;
Pew Grand Rapids Campus: Eberhard Center, parking services desk.
Nearly 200,继续提供000个非医用三层一次性口罩(这些是自大流行开始以来供应的口罩). 对于校园里的大多数人来说，这些口罩和可洗布口罩(两层)就足够了。.
Important mask details:
•不正确佩戴的KN95并不比正确佩戴的布口罩更安全.
•一次性三层口罩与双层布口罩配戴的防护效果相当于KN95口罩.
•有些人不能忍受KN95口罩，觉得呼吸困难, and might relax their mask. 他们可能会觉得双层口罩更容易忍受.
•一个干净的KN95，适当的护理应该持续五天.
- 因健康原因不能佩戴口罩者，请与残障人士联系 Support Resources (DSR).
- Students, 免疫系统较弱的教职员工应与医疗保健提供者讨论他们的活动和预防COVID-19所需的预防措施. Currently, 疾病预防控制中心建议免疫系统较弱的人继续戴口罩并保持身体距离.
- 鼓励学生、教职员工戴口罩或避免使用口罩 crowded, outdoor events, like a live performance, parade, 或体育赛事可能会带来更高的COVID-19传播风险，特别是在未接种疫苗的人群中.
- Faculty, 员工和学生有责任清洗面罩，并妥善处理一次性口罩
- 遵从性主要是通过主动性来促进的, ongoing education, communication, modeling and reduction of barriers.
Face covering FAQ
Are masks effective in preventing virus spread?
是的，口罩已被证明在防止传播方面非常有效 of the COVID-19 virus. The U.S. Center for Disease Control (CDC) 参考文献超过90项研究都显示了 戴口罩防止病毒传播(SARS、COVID-19、 Influenza, etc.). Mask wearing has demonstrated effectiveness with all the variants of concern for COVID-19.

What makes some masks more effective than others?
口罩的主要目的是防止携带病毒的气溶胶 呼出的空气不被排出到环境中. If everyone in 区内正确佩戴口罩，病毒传播成为 difficult. 两层紧密编织的布都表现得很好 细滴和微粒减少50% - 80%. This is similar to a three-layer medical procedure mask. For more information: http://www.cdc.gov/coronavirus/2019-ncov/science/science-briefs/masking-science-sars-cov2.html and http://www.nature.com/articles/s41591-020-0843-2. 注意:不要佩戴任何带有呼气阀的口罩 defeats the intended purpose of the mask.
对于佩戴者来说，口罩的有效性取决于两个标准， filter efficiency and mask fit. The filter efficiency of two-layer 布口罩对1微米颗粒的阻隔率为50%，对空气的阻隔率更高 larger aerosol sizes. Three-layer medical procedure masks are 60 - 80% efficient in capturing aerosols. KN95 and N95 masks have five layers of filters and efficiencies of 85% - 95%. Double masking, such 作为医用口罩外的布口罩(双层) (三层)或两层医用程序口罩可接近(75%至) 90+%) filter efficiencies of N-95 masks.

确定口罩功效的另一个标准是口罩的效果如何 fits. 戴着紧贴口鼻的口罩 increases the efficiency of the mask. Facial hair interferes with the fit of any mask making them less efficient. Nose wires for cloth 医用口罩，口罩钳子/牙套，以及打结和折叠 procedure masks can improve mask effectiveness. The CDC offers 优秀的指导，如何正确实现适当的配合.

口罩降低其有效性的问题是什么?
Three issues decrease the efficiency of masks. Masks not worn over the nose and mouth (incorrect use). Additionally, masks not worn by everyone in a meeting or class (inconsistent use). Lastly, a mask worn with large gaps in the sides (improper fit).
如果戴起来不舒服，口罩的效果也会降低 足以引起不断的调整和去除，以获得救济. The 面具的层数越多，呼吸就越费力. Increased 呼吸阻力和舒适度下降，可导致口罩 fatigue and decreased mask use.
面部毛发会干扰任何面具的贴合度，使它们更少 efficient. 有胡子的人应该刮胡子，修剪胡须，或者 添加一个额外的面膜，使面膜的两侧紧密闭合 against the face. For more information: http://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/mask-fit-and-filtration.html and http://www.cdc.gov/mmwr/volumes/70/wr/mm7007e1.htm?s_cid=mm7007e1_x
我应该怎样保养我的面膜?我应该使用多长时间?
Any type of mask should be kept clean and dry. Dirty masks or wet 口罩应弃置，如果是布口罩，则应清洗. Masks when 不使用时应装在纸袋里，而不是装在塑料袋里.
医用口罩和kn95应在5天后处理 of use or sooner if they become soiled or wet. For more information: http://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/about-face-coverings.html and http://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.504
