八類較少見但實用的防災物資Eight Specialist Emergency Supplies Most Homes Do Not Already Own
不再重複介紹一般家居用品,而是逐項說明用途、使用方法、選購重點、限制及購買入口。
A focused guide to use cases, selection, limits, example brands and buying routes—not another generic shopping list.
手電筒、毛毯、充電線及膠布,大部分家庭本身已有。SafeNest較值得深入介紹的,是平日較少接觸、選購不當容易造成浪費,但能在特定中斷情境補足缺口的用品。並非所有家庭均需購買以下八類用品;請先了解「最有用情境」再作決定。
Most homes already contain torches, blankets, charging cables and plasters. SafeNest therefore focuses on products that are less familiar, easy to buy badly, and capable of filling a defined gap. These are not automatic purchases—start with the use case.
我們用三條問題篩選Our three-question filter
如購買前未能回答第一項問題,便應暫緩購買。
If you cannot answer the first question, do not buy it yet.

冬季停電:一次性暖包還是可充電暖手器?Winter power cut: disposable heat packs or rechargeable hand warmers?
冬天停電,最難未必是沒有燈,而是入夜後沒有暖氣。這兩類用品不能暖房,卻可在沒有插座時為冰冷手腳提供局部保暖。
In a winter power cut, the hardest part may not be the dark but losing heating overnight. Neither product heats a room, but both can give cold hands and feet local warmth without a socket.
先看被鋪後才補缺口Fill the gap after checking bedding先問:家中是否已經夠暖?First ask: is the home already covered?
- 每人先有乾爽衣物、厚被、毛毯或睡袋。
- 選一個較小、少漏風的房間活動及休息;關上不用的房門。
- 如已有足夠寢具,暖包才是簡單、低成本的補充。
- First make sure each person has dry layers and warm bedding, blankets or a sleeping bag.
- Use a smaller, less draughty room and close unused doors.
- Where bedding is already sufficient, heat packs are a simple, low-cost addition.
它們不能做甚麼What they cannot do
- 不能把房間變暖,也不能取代厚被或睡袋。
- 可充電款的電量耗盡後便停止供暖,不是三日保暖主力。
- 絕不可因此在室內用炭爐、BBQ、戶外爐或發電機取暖。
- They do not heat a room or replace bedding.
- Rechargeable warmth ends when the battery is empty, so it is not a three-day mainstay.
- Never heat indoors with charcoal, BBQs, outdoor stoves or generators.
一次性暖包Disposable heat packs
適合:想以最低成本補一個缺口,未開封放在抽屜,停電時毋須找插頭或預先充電。按用途選暖手、暖腳或身體款;不要把暖腳款當暖手款用。英國 HotHands 的足部款標示最長約 8 小時;不同暖手/身體款的持續時間差異很大,所以要比較每包所列「最長時間」、數量及到期日,而不是只看價錢。
Best for: a low-cost drawer backup that needs no socket or advance charging. Choose hand, foot or body styles for their intended use; do not treat a foot warmer as a hand warmer. HotHands UK lists up to 8 hours for its foot warmers, but duration varies greatly by hand and body product, so compare the stated maximum, pack quantity and expiry date — not price alone.
可充電暖手器/電熱暖手包Rechargeable hand warmer
原理及適合對象:內置鋰電池把電力送到發熱元件,通常由金屬外殼或發熱面把熱傳到手掌;不是「儲熱」,電量用完便停止。適合平日等車、外出或在家怕冷也會用,希望停電第一晚多一份舒適的人。產品寫 3–6 小時或更長,往往是低檔、指定環境下的數字;天氣越冷、開得越熱,時間越短。
How it works and who it suits: an internal lithium battery powers a heating element, usually transferring heat through a metal shell or heating surface. It does not store heat: once the charge is gone, warmth stops. It suits people who will also use it for commuting or everyday cold hands and want extra comfort on the first outage night. Claims of 3–6 hours or longer are commonly based on a low setting in stated conditions; colder weather and higher heat shorten runtime.
| 選購時真正要比較What to compare | 一次性暖包Disposable | 可充電暖手器Rechargeable |
|---|---|---|
| 開用前的準備Before use | 保持原封;一拆開才讓空氣啟動。Keep sealed until needed; air starts it. | 先充滿電,長期閒置仍要按說明書定期補電。Charge before it is needed; top up periodically in storage as the manual directs. |
| 時間與用途Runtime and role | 看該款包裝的「最長」發熱時間;適合抽屜後備和手/腳局部保暖。Use that product’s stated maximum; good for drawer backup and local hand/foot warmth. | 同時比較低/高檔續航;只當作第一晚或短時間的舒適補充。Compare low- and high-setting runtime; treat as a first-night or short-use comfort extra. |
| 規格怎樣看Reading specifications | 用途、包裝數量、到期日及有否清楚列出使用位置。Intended body area, pack count, expiry and clear placement directions. | 不要只看 mAh;如有 Wh(瓦時)更容易比較實際儲電量。看 USB-C 充電、清楚的溫度檔位、說明書及售後資料。兼作 power bank 代表同一粒電要分給手機與保暖,不能兩邊都預計用足。Do not judge by mAh alone; Wh is easier to compare when shown. Look for USB-C charging, clear heat settings, a manual and support details. A power-bank function shares the same battery with warmth, so do not expect full use of both. |
冬季停電/撤離:補足「不靠插座」的保暖缺口Winter outage or evacuation: close the no-socket warmth gaps
以下三樣是八類核心物資以外的冬季加項;每樣只解決一個明確缺口。袋形 thermal bivvy 已是八類中的獨立項目,詳見下方。
These three are winter additions beyond the core eight, each solving one defined gap. The thermal bivvy is already a separate item within the eight; see below.
先備乾衣、被鋪與避風處Start with dry layers, bedding and shelter
一次性暖包Disposable heat packs
適合放在抽屜或撤離袋的低成本後備:未開封時不用充電;需要時為手、腳或衣物口袋提供局部熱力。
A low-cost drawer or grab-bag backup: it needs no charging while sealed, then adds local warmth to hands, feet or clothing pockets when needed.
最易先備的一樣The easiest first addition用途與原理Purpose and principle
英國常見的空氣啟動款含鐵粉、活性碳、水及輔助材料。拆開外袋,氧氣穿過袋面,鐵粉氧化(受控「生鏽」)並放熱;所以它不是電池,也不能再充電、微波或烘熱重用。
Common UK air-activated packs use iron powder, activated carbon, water and supporting materials. Opening the outer pouch lets oxygen reach the iron, which oxidises and releases heat. It is not a battery and must not be recharged, microwaved or reheated.
如何使用/如何選Use and choose
按標示選暖手、暖腳或身體款;暖腳款一般放在襪外、鞋內,不是直接貼皮膚。比較用途、每包數量、到期日及包裝所列「最長發熱時間」;例如 HotHands 足部款最長約 8 小時,但不同款式相差很大。
Choose hand, foot or body styles as labelled. Foot warmers normally go outside the sock, inside the shoe—not on bare skin. Compare intended use, pack count, expiry and the stated maximum duration; HotHands foot warmers list up to about 8 hours, but products vary widely.

可充電暖手器/電熱暖手包Rechargeable hand warmer
適合平日等車、外出或在家怕冷也會使用的人;停電時可作第一晚的舒適補充,但不是三日保暖主力。
Best for people who will also use it while commuting or at home. In an outage it can add first-night comfort, but it is not a three-day heat solution.
先有日常用途才值得買Best when it has everyday use用途與原理Purpose and principle
內置鋰電池把電送到發熱元件,再由金屬外殼或發熱面傳到手掌。它不是「儲熱」:電量耗盡便停止。產品所寫 3–6 小時或更長,通常是低檔、指定環境下的數字;越冷或開得越熱,時間越短。
An internal lithium battery powers a heating element, which transfers warmth through the casing or heating surface. It does not store heat: warmth ends with the charge. Claims of 3–6 hours or more are commonly at a low setting in stated conditions; cold weather and higher heat shorten runtime.
如何使用/如何選Use and choose
比較低/高檔續航、USB-C 充電、清楚的溫度檔位、說明書及售後資料。如有 Wh(瓦時)會比只看 mAh 更容易比較儲電量。兼作 power bank 代表手機與保暖共用同一電量,不能兩邊都預計用足。
Compare low- and high-setting runtime, USB-C charging, clear heat levels, a manual and support information. Wh (watt-hours), where shown, is easier to compare than mAh alone. A power-bank function shares one battery between phone charging and warmth.

閉孔泡棉睡墊/露營地墊Closed-cell foam sleeping mat
若要在車內、避難中心地板或戶外短暫等候,隔開身體與冰冷地面往往比再加一件上衣更有用。
For a car, shelter floor or short outdoor wait, separating the body from cold ground can matter more than one extra top layer.
撤離袋與車載較值得放Especially useful in a grab bag or car用途與原理Purpose and principle
身體躺、坐或跪在石屎、車廂地板或濕地時會不停失熱。閉孔泡棉內的氣泡不易吸水,能形成較可靠的隔熱層;它不會發熱,但能減慢地面吸走體溫。
When you lie, sit or kneel on concrete, a vehicle floor or wet ground, heat is continually lost. Closed-cell foam resists water absorption and creates a reliable insulation layer. It does not generate heat; it slows heat loss to the ground.
如何使用/如何選Use and choose
先鋪墊,才坐或鑽進睡袋;可放在睡袋下,也可摺起作坐墊。選可摺或可捲、展開後能覆蓋軀幹長度、表面不易吸水的閉孔泡棉款。充氣墊較舒適但可能漏氣;撤離後備以泡棉較穩陣。
Lay it down before sitting or getting into a sleeping bag. Use it under the bag or folded as a seat pad. Choose a foldable or rollable closed-cell foam mat that covers the torso length and resists water. Inflatable mats can be comfier but may puncture; foam is the steadier evacuation backup.

高熱量長效應急口糧棒High-calorie emergency ration bars
適合放入緊急疏散袋,或作為體積小巧的後備食品;並非用來取代家中三日的正常食物。
Useful in a grab bag or as a very compact fallback—not a replacement for three days of normal household food.
值得考慮的新增項目Best new addition最有用情境Best use case
- 要疏散,而背包重量及體積有限。
- 停電停水,完全不能加熱或煮食。
- 平日食物用完後的一層封存後備。
- Evacuation with tight weight and space limits.
- No safe cooking or heating route.
- A sealed fallback after familiar food is used.
未必適合When it is a poor fit
- 居家儲糧:罐頭、燕麥餅及長效奶通常價格較低,也較容易入口。
- 對麩質、大豆或其他食物敏感,但尚未核對標籤的人士。
- 誤以為包裝標示「72 hour」,便足以提供一名成人三日所需的全部食物。
- Home stores, where familiar long-life food is usually cheaper and more palatable.
- Anyone who has not checked allergens.
- Assuming a “72 hour” label equals three full days of adult energy.
| 例子Example | 包裝能量Pack energy | 標示保存期Stated shelf life | 要留意Check |
|---|---|---|---|
| NRG-5 | 500g / 2,300 kcal | 製造日起20年20 years from production | 即食;含小麥、大豆及大麥成分。按實物標籤為準。Ready to eat; contains wheat, soya and barley ingredients. Check the delivered label. |
| Seven Oceans | 500g / 2,500 kcal | 5年5 years | 9條壓縮口糧;供應資料列為 Halal。仍須核對到期日及致敏原。Nine compressed bars; supplier data lists it as Halal. Check expiry and allergens on arrival. |
| Datrex | 1,000/2,400/3,600 kcal 包裝1,000 / 2,400 / 3,600 kcal packs | 製造日起5年5 years from production | 即食及分件包裝;英國供應較不穩定,應核對賣家、到期日及寄送地點。Ready to eat and portioned; UK supply varies, so check seller, expiry and dispatch origin. |

緊急保溫毯/袋形 thermal bivvyEmergency foil blanket / thermal bivvy
薄毯最適合疏散、等候救援或臨時防風防雨;留在家中時仍應優先使用乾爽衣物、普通毛毯及睡袋。
Best for evacuation, waiting for help, and temporary wind or rain protection. At home, dry layers, normal blankets and sleeping bags remain the priority.
緊急疏散袋選配Grab-bag option平面銀色保溫毯Flat foil blanket
體積極小,可作一次性後備,但容易撕裂及積聚水氣。每個緊急疏散袋放置一張即可,毋須大量囤積。
Tiny emergency backup that can tear and trap condensation. One per grab bag is enough.
袋形 emergency bivvyBag-shaped emergency bivvy
袋形設計較能減少四周進風;應選擇清楚列明尺寸、封邊方式及能否重複使用的款式。
A bag shape limits drafts. Check dimensions, sealed seams and whether it is reusable.
透氣/可重用 bivvyBreathable reusable bivvy
重量及價格較高,但通常較少積聚水氣;適合已有睡袋並需要增加防風防水層的人士。
Heavier and dearer, but generally less clammy. Useful as a weather-resistant layer around a sleeping bag.

10–15L 食品級儲水桶(附水龍頭)10–15L food-grade water carrier with tap
用於在水車、派水點或收到短期停水通知後取水;不應取代家中的原廠密封樽裝飲用水。
For collecting water from a bowser or distribution point, or after short notice. It does not replace commercially sealed bottled water at home.
適合停水時使用Useful for outages實用選購重點What to choose
- 清楚標示適合飲用水/food grade。
- 闊口,方便伸手或使用刷具清洗。
- 密封蓋不漏水;水龍頭可拆洗,並附有備用墊圈更佳。
- 方形設計可直立及方便收納;兩個較小的儲水桶亦可減少單一容器漏水的風險。
- Explicitly food-grade / suitable for potable water.
- A wide opening that can be cleaned properly.
- A leakproof cap and removable, cleanable tap.
- A stable shape; two smaller carriers reduce single-point failure.
容量不宜過大Do not oversize it
- 一公升水約重一公斤;15公升容器裝滿後已約重15公斤,尚未計算容器重量。
- 20公升容器對長者、兒童或需要上下樓梯的家庭而言可能過重。
- 購買後應先注滿水,測試手柄、蓋及水龍頭,切勿待停水時才首次試用。
- One litre of water weighs about one kilogram; a full 15L carrier is about 15kg before the container.
- 20L may be too heavy for stairs, children or older adults.
- Fill-test the handle, cap and tap before an outage.

Aquatabs/Oasis/Lifesystems 類淨水片Aquatabs / Oasis / Lifesystems-type tablets
體積小、扁平且容易保存,但只適用於產品列明的水源及微生物風險;並非能處理所有污染物。
Compact and easy to store, but only for permitted source water and microbiological risk—not a universal detoxifier.
有明確用途才購買Defined use only購買時檢查四項資料Four checks
- 每片可處理多少公升,不應只比較片數。
- 有效日期及未開封時的保存方法。
- 所需等待時間;不同產品及病原體的要求可能相差甚遠。
- 成分屬氯類還是二氧化氯,並須嚴格按照包裝所列劑量使用。
- Litres treated per tablet—not merely tablet count.
- Expiry and sealed-storage requirements.
- Contact time, which varies by product and organism.
- Chlorine versus chlorine dioxide; follow the exact dose.
不能處理的污染What tablets do not solve
- 泥沙:混濁水須先按照官方指引過濾。
- 鹽水、燃油、農藥、重金屬或其他溶解化學物。
- 放射性污染。
- 水務公司發出的「Do Not Drink/Do Not Use」通知。
- Sediment; cloudy water needs pre-filtration as instructed.
- Salt, fuel, pesticides, heavy metals or other dissolved chemicals.
- Radiological contamination.
- A water-company “Do Not Drink / Do Not Use” notice.

便攜微濾器Portable water microfilter
常見個人款讓水通過精細濾膜,可按產品規格隔除泥沙、細菌及寄生蟲;一般不能處理病毒、鹽或溶解化學物。
Common personal models pass water through a fine membrane and, depending on specification, remove sediment, bacteria and parasites. They usually do not treat viruses, salt or dissolved chemicals.
只適用於指定水源For defined water sources如何使用How to use it
- 只處理製造商明確列明可用的水源。
- 保持出水端清潔,避免已處理的水再次受到污染。
- 按說明反沖洗、晾乾及防止濾芯結冰。
- Use only with water sources explicitly allowed by the maker.
- Keep the clean-water outlet free from cross-contamination.
- Backwash, dry and protect the cartridge from freezing as instructed.
如何選擇What to choose
- 查看廠方列明可處理的微生物,不應只看「過濾精度」的宣傳字句。
- 比較處理容量、流速、反沖洗方法及替換零件。
- 確認軟水袋、喉管及接頭可單獨補購。
- Check the organisms covered, not only headline pore-size claims.
- Compare capacity, flow rate, backwashing and replacement parts.
- Check whether pouches, hoses and connectors can be replaced.

較完整的便攜淨水器Broader portable water purifier
只有明確標示為 purifier,並列明可處理病毒等污染物的產品,才可視為比一般微濾器提供更廣泛的處理能力;不同濾芯的效能差異很大。
Only products explicitly rated as purifiers, with stated virus and contaminant performance, provide broader treatment than a basic microfilter. Cartridge capabilities vary widely.
高成本的特定用途選項Higher-cost defined-use option與微濾器有何分別How it differs from a microfilter
- 產品應清楚列明可處理的病毒、細菌及寄生蟲,而非只寫「淨化」。
- 部分濾芯另有活性碳層,可減少指定化學物、氣味或味道;能力必須按個別規格判斷。
- 較多處理層通常代表較重、流速較低及濾芯成本較高。
- It should state virus, bacteria and parasite performance, not merely say “purifies”.
- Some cartridges add activated carbon for specified chemicals, tastes or odours; capabilities are product-specific.
- Broader treatment usually adds weight, slower flow and cartridge cost.
如何使用及選擇How to use and choose
- 按說明完成按壓或泵水步驟,避免出水端接觸未處理的水。
- 比較可處理的污染物、濾芯壽命、更換成本、重量及處理速度。
- 購買前先確認英國可否長期取得替換濾芯。
- Follow the pressing or pumping method and protect the clean-water outlet.
- Compare stated contaminants, cartridge life, replacement cost, weight and speed.
- Check long-term UK availability of replacement cartridges.

卡式氣爐及相容丁烷氣罐Cassette stove and compatible butane cartridges
家中主要使用電磁爐或電爐時,卡式氣爐可在停電期間煲水、加熱罐頭及煮簡單食物。這是居家儲備,不是疏散袋的必備品。
For homes that rely on electric hobs, a cassette stove can boil water, heat tins and make simple food during a power cut. It belongs in home storage, not as a grab-bag essential.
有電爐家庭值得考慮Useful for electric-cooking homes先核對三件事Check three things first
- 說明書必須明確允許室內煮食;未有清楚列明時,便不要在室內使用。
- 只購買製造商指定接口的氣罐。常見長身227g卡式丁烷罐與螺紋露營罐不互通。
- 先在平日試用,按說明書的耗氣量和你家的餐次計算後備罐數,而不是只按「幾罐裝」購買。
- The manual must explicitly permit indoor cooking; if it does not, do not use it indoors.
- Buy only the cartridge connection specified by the maker. Common long 227g cassette-butane cans and threaded backpacking canisters are not interchangeable.
- Test it in normal times and calculate backup cans from the manual's consumption figure and your planned meals—not simply by pack size.
使用及存放Use and storage
- 放在穩固、耐熱平面,保持周邊通風,遠離窗簾、紙張及其他易燃物。
- 用完即拆下氣罐;將氣罐置於陰涼、乾爽及遠離熱源處,勿長期放在車內。
- 不可使用露營爐、BBQ、炭爐或發電機作室內替代品;一氧化碳警報器不能令錯誤使用變得安全。
- Use on a stable, heat-resistant surface with ventilation, away from curtains, paper and other flammables.
- Remove the cartridge after use; store it cool, dry and away from heat, never long-term in a car.
- Never substitute an outdoor camping stove, barbecue, charcoal burner or generator indoors; a CO alarm does not make unsafe use safe.

防水/耐火文件袋Water- / fire-resistant document bag
防水袋主要保護文件免受雨水及潑濺;聲稱耐火的款式屬另一類產品,其保護程度取決於物料及測試資料,兩者均不能取代保險箱及數碼備份。
Waterproof bags mainly protect against rain and splashes. Fire-resistant models are a different category whose protection depends on materials and test evidence. Neither replaces a safe and digital backups.
適合存放緊急文件副本Useful for emergency copies應放置甚麼What to keep inside
- 打印的緊急聯絡資料、保單資料及重要文件副本。
- 少量備用現金及不含敏感密碼的必要資料。
- 重要原件另行安全存放,並建立加密雲端備份。
- Printed emergency contacts, insurance details and copies of key documents.
- A small amount of cash and essential information without sensitive passwords.
- Store originals securely elsewhere and keep encrypted cloud backups.
如何選擇What to choose
- 查看是否容納A4文件,以及封口、拉鏈與接縫能否防止潑濺。
- 如聲稱耐火,應查看清楚列明的測試條件、時間及溫度,不應只依賴「fireproof」字樣。
- 選擇可放入緊急疏散袋、由家人容易攜帶的尺寸。
- Check A4 fit and whether the closure, zip and seams resist splashes.
- For fire-resistance claims, look for stated test conditions, time and temperature—not only the word “fireproof”.
- Choose a size that fits the grab bag and can be carried easily.
