OldNeighbour 正在举办一场免费食品运动,以帮助那些受冠状病毒影响的人群。
各种封锁严重打击了社会的边缘化群体,影响了他们生活。
对此,OldNeighbour希望透过各大商家的分享来帮助到有需要的人群。
我们邀请那些有需要的人来到我们OldNeighbour指定的商家领取每人2份的食物。
任何查询,请通过Whatsapp联系我们:+6011-1095 9598(OldNeighbour客服人员)
OldNeighbour is running a free food campaign to help people affected by coronaviruses.
The blockades have severely affected marginalized groups in society and affected their lives.
In response, OldNeighbour hopes to help people in need through the sharing of major businesses.
We invite those in need to come to our OldNeighbour selected merchants to receive 2 servings of food per person.
For any enquiries, please contact us via Whatsapp at: +6011-1095 9598(OldNeighbour customer service)

☀ #紫外燈(UVC)快問快答⏳
紫外燈UVC可以殺 #新冠肺炎 嗎❓ #曬太陽可以殺菌嗎❓ #臭氧消毒安全嗎❓
目前COVID-19疫情持續延燒感覺沒有盡頭,除菌消毒設備更是夯到不行❗有家長問我紫外燈到底有沒有用?今天就幫大家解答一下,希望對大家有幫助💗
--
📣 Q1. UVC可以殺SARS-CoV2嗎?
#可能有效,但目前醫學實證數據還不足,有效或沒效的文獻都查的到。應使用的 #波長、#時間、#能量 大小都還不確定😭
所以 #不能以為靠紫外燈消毒環境就安全無虞,還是要靠勤洗手、酒精或漂白水消毒環境💓
--
📣 Q2. UVC是什麼?
波長100-280 nm的紫外光,能量強可破壞微生物的DNA。可用於 #空氣消毒、物體 #表面消毒,對絕大部分的細菌、病毒、黴菌有效👏
--
📣 Q3. 曬太陽可以殺菌嗎?
太陽光有殺菌效果的UVC,絕大部分會被 #臭氧層吸收⛅所以 #不能靠太陽光來殺菌,同理可證艷陽高照的東南亞也無法逃脫COVID-19的魔掌😱
💔戶外曬太陽主要是照到
🔥 #UVA 95% (造成皮膚 #老化、皺紋)
🔥 #UVB 5% (造成皮膚紅、熱、#皮膚癌)
--
📣 Q4. UVC不同波長的特殊效果?
⭐254 nm最常用:15.54 (mW/cm2)能量,照射一分鐘殺死絕大部分細菌
⭐ 207-222 nm對人體 #皮膚、#眼睛傷害較小
⭐ 185 nm會激發氧氣變成 #臭氧 O₃
--
📣 Q5. UVC穿透力差
❎ UVC #無法穿透灰塵、泥土、體液
❎ 紙片、玻璃、#霧氣 都會大大降低照射強度。
❎ 病菌藏在有 #孔洞 的表面也會照不到
❎ 物體的 #背光面 也沒有效果
--
📣 Q6. UVC對人體有害?
🆖 刺激或 #灼傷皮膚
🆖 傷害 #眼睛角膜
🔷 但因穿透力弱,極少造成皮膚癌或是白內障
--
📣 Q7. 燈管為什麼會釋放臭氧?
✅ 燈管釋放紫外線中,185 nm波長的UVC會 #激發空氣中的氧氣變成臭氧 O₃
✅ 經添加特殊成份之石英玻璃管,可有效控制185nm波長UVC的量,達到控制臭氧的多寡
✅ 臭氧可以 #擴散到光線照射不到 的地方,進行殺菌
--
📣 Q8. 臭氧對人體有害?
⛔ #刺激呼吸道、造成氣喘
⛔ 呼吸道變脆弱反而 #增加呼吸道感染機會
🔺 8小時室內臭氧平均容許暴露值0.1ppm
--
📣 Q9. 紫外燈使用注意事項
⭐ #不可用於人體消毒
⭐ 消毒時 #不可以在同一房間
⭐ 有臭氧功能的最好照射結束後 #通風30-60分鐘
🎯 參照每台紫外燈的建議 #照射時間
最好30-60分鐘以上
🎯 注意有效照射 #空間範圍
15瓦照射範圍2.8坪
30瓦照射範圍5.6坪
⭐ #擦拭清潔燈管,以免灰塵影響效能
♟ 會造成塑膠或矽膠材質老化、染色物品變色

coronaviruses 在 作者 Facebook 的精選貼文
從前武漢有個病毒實驗室,有一天,三個研究員一齊去睇醫生……
//Three researchers from China’s Wuhan Institute of Virology became sick enough in November 2019 that they sought hospital care, according to a previously undisclosed U.S. intelligence report that could add weight to growing calls for a fuller probe of whether the Covid-19 virus may have escaped from the laboratory.
The details of the reporting go beyond a State Department fact sheet, issued during the final days of the Trump administration, which said that several researchers at the lab, a center for the study of coronaviruses and other pathogens, became sick in autumn 2019 “with symptoms consistent with both Covid-19 and common seasonal illness.”//
