當廚房中的玻璃烤盤、玻璃鍋蓋或強化玻璃爐灶因熱衝擊或物理撞擊而破碎時,它們很少會碎成兩到三塊。相反,經過熱強化和鋼化的鈉鈣玻璃會瞬間釋放儲存的內部張力,爆炸時會發出一聲巨響,將數千個鋒利的碎片和看不見的微小玻璃針射到檯面、打開的食物罐、廚房地板和赤腳上,最遠可達 5 米(16 英尺)。
本指南解釋了在玻璃烤盤或微晶玻璃爐具破碎後的前六十秒內該怎麼做,如何保護家庭成員和寵物免受隱藏的玻璃碎片的傷害,當食品安全機構要求您不吃一口就扔掉附近的食物時,如果有人吞下一塊玻璃該怎麼辦,以及如何在溢出的液體導致高壓短路之前斷開破裂的電動或電磁爐具。
現在就這樣做¶
- 將每個人都固定在原地,告訴家人不要赤腳或赤腳邁出一步,並將兒童和寵物帶出廚房:鋼化玻璃爆炸將透明的針狀碎片推進整個房間並進入相鄰的走廊,在閃亮的瓷磚或硬木地板上它們完全看不見,直到有人踩到它們。
- 在採取另一個步驟之前,穿上硬底鞋和厚厚的工作或洗碗手套:如果您的鞋子在另一個房間,並且您被困在玻璃覆蓋的廚房地板上,請在腳前鋪上厚浴巾、紙板箱或廚房墊作為臨時橋樑,直到您可以穿上堅固的閉趾鞋。
- 如果玻璃爐臺本身破裂或破碎,請關閉烤箱、爐灶燃燒器或關閉 240 伏特廚房灶斷路器:當加熱元件或指示燈通電時,切勿觸摸破裂的電動或感應玻璃爐灶,切勿讓沸水或鍋內液體通過滲入下面的帶電高壓裂縫線路。
- 至少等待 30 到 45 分鐘,讓熱爆炸的玻璃烤盤和溢出的食物冷卻下來,然後再觸摸或清掃:撿起 200 攝氏度(400 華氏度)的玻璃碎片會導致三度熱燒傷和深度肌腱撕裂,將冷水倒在爐子上的熱玻璃碎片上會導致二次爆炸性破碎。
- 100% 丟棄玻璃碎片 3 至 5 公尺(10 至 16 英尺)範圍內任何未覆蓋的食物、飲料、冰桶或配料:切勿嘗試從食物或飲料中沖洗、過濾、篩分或拾取碎玻璃;微小的玻璃碎片在潮濕時是完全透明的,無法可靠過濾,如果吞嚥可能會刺穿食道或腸道。
- 如果有人的眼睛裡可能有玻璃顆粒,請告訴他們不要摩擦或擠壓眼瞼,並沖洗或立即尋求緊急眼部護理:摩擦含有微小玻璃顆粒的眼睛會將鋒利的二氧化矽邊緣直接推入角膜;用無菌鹽水洗眼液輕輕沖洗或立即尋求臨床評估(請參閱我們的 眼睛受傷 指南)。
Danger
切勿使用帶有旋轉攪拌棒(刷輥)或柔性塑膠軟管的標準家用立式吸塵器來吸走大或中型碎玻璃碎片。旋轉的刷輥將微小的玻璃針拋回到腳踝高度的空氣中,而鋒利的玻璃碎片會切穿吸塵器的內部橡膠軟管和布塵袋,永久污染機器,因此您以後每次用吸塵器吸地毯時,它都會噴出玻璃灰塵。使用紙板或鉗子用手拿起所有可見的碎片,徹底清掃,最後用濕紙巾、膠帶或一片軟麵包完成。

為什麼玻璃烤盤和鍋蓋突然爆炸:硼矽酸鹽與鋼化鈉鈣玻璃¶
最令人震驚的廚房事故之一發生在廚師從熱烤箱中取出玻璃砂鍋菜,將其放在檯面或爐灶上,或者在乾燥的烤盤中加入少量酒或肉湯時,菜餚突然像鞭炮一樣爆炸。
热冲击和内回火应力的物理学¶
了解玻璃烤盤爆炸的原因可以幫助您識別櫥櫃中的哪些餐具容易受到傷害:
- 硼矽酸鹽玻璃(傳統實驗室和經典歐洲玻璃):從歷史上看,經典的烤箱安全玻璃烤盤是由硼矽酸鹽玻璃(二氧化矽與三氧化硼混合)製造的。硼矽酸鹽玻璃具有極低的熱膨脹係數(約 \(3.3 \times 10^{-6}\text{ K}^{-1}\)),這意味著當盤子的一側較熱而另一側接觸冷表面時,玻璃的膨脹和收縮最小,並能抵抗熱衝擊。當硼矽酸鹽玻璃因掉落而破裂時,它會裂成幾塊大塊,而不是爆炸。
- 強化鈉鈣矽酸鹽玻璃(現代大眾市場烤盤和鍋蓋):在過去的幾十年裡,北美和全球的許多製造商將消費玻璃烤盤和鋼化玻璃鍋蓋轉變為熱鋼化鈉鈣玻璃。雖然鋼化提高了對水槽水龍頭碰撞的機械阻力,但在快速加熱或冷卻時,鈉鈣玻璃的膨脹和收縮幾乎是硼矽酸鹽玻璃的三倍。
- 為什麼強化鈉鈣玻璃會劇烈爆炸:熱鋼化的工作原理是快速冷卻熔融玻璃盤的外表面,而內核緩慢冷卻。這將外皮鎖定在高壓應力,而內部核心鎖定在高拉(拉)應力。如果局部熱衝擊(例如將 200 攝氏度/400 華氏度的碟子放置在潮濕的花崗岩檯面、未點燃的金屬燃燒器環上,或將較冷的液體倒入乾熱的碟子中)或看不見的微觀划痕導致裂縫滲透到內部拉伸中,哪碟子以每碟子釋放為一毫米,從而將整個能量儲存超過 500 米碟子以每碟子釋放成光盤。数以千计的飞行立方体和针。
引发玻璃烤盘爆炸的七个动作¶
切勿讓任何玻璃烤盤、玻璃派盤或玻璃量杯受到以下七種熱衝擊觸發因素的影響:
- 切勿將玻璃烤盤放在烤箱(燒烤元件)下方或靠近暴露的石英/金屬加熱元件的烤麵包機烤箱內,其中紅外線輻射熱超過 260 攝氏度(500 華氏度)。
- 切勿將玻璃盤直接放在爐子燃燒器的頂部(燃氣、電線圈、光滑頂部輻射或感應),即使燃燒器已關閉;餘熱或冷金屬燃燒器環會產生極端的局部熱應力,從而引爆玻璃烤盤。
- 切勿將玻璃盤從烤箱中取出,並將其放置在裸露的花崗岩、石英、大理石、不銹鋼或濕檯面上或濕抹布上。即使是一條幾乎不濕的毛巾也會立即變成蒸汽,從玻璃底部的一個地方吸走熱量,從而引發爆炸。 **請務必將熱玻璃烤盤嚴格放置在乾燥、厚的折疊棉質隔熱墊、乾燥軟木三腳架或乾燥木切板上。 **
- 切勿將液體(肉湯、水、酒或冷醬)或冷凍蔬菜加入已放入烤箱的熱乾玻璃盤中。
- 切勿直接從冷凍室或冰箱中取出玻璃盤並將其放入預熱的烤箱中;首先讓盤子在櫃檯上達到室溫,並在插入玻璃烤盤之前始終將烤箱完全預熱,這樣底部加熱元件在預熱週期中就不會用全瓦數輻射熱加熱盤子。
- 切勿在底部未覆蓋液體、油或黃油的玻璃盤中烹飪乾肉或蔬菜;玻璃裸露的干燥區域過熱,遠遠超過潮濕食物覆蓋區域的溫度,從而在鍋底形成致命的溫差。
- 檢查玻璃皿是否有跳蚤叮咬、碎片和金屬器皿划痕:如果玻璃烤盤的邊緣有微小碎片,或者底部有金屬抹刀或刀具造成的深深划痕,請立即將其從烤箱中取出,因為表面划痕會充當應力集中器,即使在玻璃烤盤放在櫃檯上冷卻幾分鐘後,也可能導致延遲自發破碎。
厨房玻璃危害和安全应对措施比较¶
| 玻璃緊急狀況 | 主要直接危險 | 電氣或火災風險 | 食品污染規則 | 所需的補救措施 |
|---|---|---|---|---|
| 玻璃烤盘在烤箱内爆炸 | 門打開時熱玻璃碎片飛濺;手部嚴重燒傷;玻璃碎片落入底部加熱元件或氣體點火器艙。 | 中度:食物油脂和玻璃落到發光的 2,500 瓦電烘烤元件上可能會引發油脂火災。 | 100% 丟棄烤箱內的所有食物(甚至其他架子上的盤子)。 | 保持烤箱門關閉,立即關閉烤箱,讓其完全冷卻 60 分鐘,然後打開門並清潔腔體、架子和門墊圈。 |
| 玻璃烤盤或鍋蓋在檯面/爐子上爆炸 | 高速彈片擊中眼睛、臉部、赤腳和寵物;煮沸的食物濺到皮膚上。 | 除非液體溢出到未密封的電燃燒器容器中,否則溫度較低。 | 丟棄3 至 5 公尺(10 至 16 英尺) 範圍內所有未覆蓋的食物、碗、打開的調味品罐和冰塊。 | 疏散廚房,穿上硬底鞋,讓熱玻璃冷卻 30 至 45 分鐘,然後使用手電筒照射進行 4 階段地板和櫃檯清掃。 |
| 破裂或破碎的微晶玻璃爐具(電動或電磁爐) | 高壓240伏特電擊和沿著骨折線的鋒利玻璃邊緣。 | 非常高:沸水、湯或清潔噴霧從細小的裂縫中滲入,接觸帶電的 240 伏特帶狀元件或感應線圈,導致電弧閃光、機櫃火災或觸電。 | 僅當玻璃爐灶向上碎裂進入敞開的鍋中時才應丟棄食物。 | 立即關閉主配電盤上的240伏特雙極斷路器;在更換玻璃陶瓷頂部組件之前,切勿再次在破裂的玻璃爐灶上做飯。 |
| 嬰兒奶瓶、玻璃瓶或水杯上有缺口的玻璃邊緣 | 吞下混入配方奶粉、嬰兒食品、罐頭蜜餞或冰沙中的彎曲新月形邊緣的條子。 | 沒有任何。 | 強制 100% 處置整個罐子或瓶子的內容物;切勿用打開時邊緣有缺口的罐子餵嬰兒或成人。 | 將破損的罐子包裹在厚紙板或防刺穿容器中,然後放入垃圾桶,以免環衛工人被割傷。 |
| 廚房水槽或垃圾處理器內的碎玻璃 | 當把手伸入混濁的洗碗水或處置排水管時,手和手指肌腱深度撕裂;玻璃堵塞處置葉輪葉片。 | 如果有人伸手去拿插入式處理器,則為中等程度。 | Rinse and carefully inspect any intact dishes that were in the sink under bright light. | Unplug the garbage disposal under the sink (or flip the breaker), drain the sink water using a long wooden spoon to move the stopper, and extract glass from the disposal using needle-nose pliers, a wet/dry shop vacuum, or half a raw potato pressed onto the shards. |
First aid and medical decision protocol if someone swallows a piece of glass¶
當您或您的孩子吞下幾口食物後,發現玻璃杯邊緣有缺口或盤子底部有玻璃碎片,這真是太可怕了。遵循毒物控制中心和兒科胃腸病學會建議的實證醫療分流方案:

Why you must NEVER induce vomiting after swallowing glass¶
When someone swallows a sharp foreign object like a glass sliver, a natural panic reaction is to try to make them gag or vomit to bring it back up. Never induce vomiting, and never give syrup of ipecac or salt water. Swallowing is a coordinated muscular wave (peristalsis) that relaxes the esophageal sphincters ahead of the bolus. Vomiting, by contrast, is a violent, high-pressure reverse spasm that forces stomach acid and the sharp glass shard forcefully against the delicate walls of the lower esophageal sphincter, throat, and airway, doubling the risk of a life-threatening esophageal perforation.
Emergency Department red flags vs home observation¶
- Go to the nearest Hospital Emergency Department immediately (or call your local emergency number: 911 in the US/Canada, 112 in the EU, 999 in the UK) if the person has any of the following symptoms:
- 喉嚨、頸部或胸部有異物卡住或抓癢的感覺(異物球感)。
- 吞嚥唾液或水時疼痛(吞嚥疼痛)或吞嚥困難(吞嚥困難)。
- 流口水、吐唾液、作嘔、氣喘或咳嗽(尤其是無法用言語表達喉嚨疼痛的嬰兒和幼兒)。
- 唾液、嘔吐物或糞便中是否有血。
- 胸骨後方的胸部疼痛、上腹部疼痛、痙攣或腹部僵硬/壓痛。
- 您知道吞下的碎片長度超過 1 到 2 公分(0.4 到 0.8 英吋),或具有彎曲、鋸齒狀的匕首形狀。
- 醫生如何評估吞下的玻璃(以及為什麼 X 射線有時會漏掉它):與“只有含鉛晶體在 X 射線上顯示”的古老神話相反,綜合放射學研究證實,幾乎所有大於 2 毫米(1/16 英寸) 的家用鈉鈣、硼矽酸鹽和鋼化玻璃碎片都是不透射線的(在普通 X 射線上可見標準,因為普通組織毫米或被脊椎骨遮蔽的碎片可能需要低劑量電腦斷層掃描 (CT) 掃描或內視鏡評估。
- 如果該人完全沒有症狀,只能吞下微小的斑點:一旦被毒物控制中心或您的醫生清除以進行家庭觀察,正常的胃腸蠕動會在 2 至 7 天內將 80% 至 90% 的攝入的小異物安全地通過消化道,這些異物塗有粘液和糞便。給患者富含柔軟、粗大纖維的正常膳食(例如軟麵包、燕麥片、土豆泥、香蕉和麵食)和大量的水,避免服用瀉藥(瀉藥會導致尖銳物體周圍的腸道快速痙攣收縮,而不是讓大便圍繞和緩衝它),如果下週出現任何腹痛、發燒、嘔吐或黑色/血便,請立即前往急診室。
清理破碎玻璃的 4 階段專業方案¶
當廚房中的強化玻璃爆炸時,只需掃過地板中間就會留下數百個針尖的微碎片,這些碎片隱藏在踢腳板、冰箱踢板下方和瓷磚灌漿線中。使用這個系統的 4 階段方法,從門口向內進行:
第一階段:清理安全站立區域並用手清除大碎片¶
- 穿上硬底鞋,戴上護目鏡,戴上厚重的防割手套或皮/橡膠手套,準備一個防刺穿處理容器(一個堅固的紙板箱,內襯兩個厚塑料垃圾袋,或一個硬塑料桶:切勿將鬆散的玻璃直接扔進薄塑料廚房垃圾袋中,這會切開並傷害您或環衛工人)。
- Starting at the outer perimeter of the room and working inward toward the center of the break, pick up all large and medium glass pieces using kitchen tongs, a stiff piece of cardboard, or a dustpan (not your bare fingers, even inside thin latex gloves) and place them directly into the cardboard box.
- Shake out any kitchen rugs, runners, or dish towels that were on the floor over a large contractor trash bag outdoors, or wash/discard them if they are embedded with fine tempered glass needles (note: never put glass-contaminated rugs into your family washing machine, as glass splinters stay trapped inside the washing machine drum perforations and embed into your family's underwear and clothing on the next cycle).
Stage 2: Stiff-bristle sweeping from corners and appliances inward¶
- Use a stiff-bristled broom and dustpan to sweep from the edges of the room, under the toe-kicks of all base cabinets, and beneath the front edge of the stove, dishwasher, and refrigerator toward the center of the floor.
- Sweep with short, controlled strokes rather than fast flicking motions (which launch small glass cubes across the room).
- After sweeping the floor into the dustpan, take the broom outside and tap and rinse the bristles thoroughly with a garden hose over gravel or dirt so glass splinters stuck between the broom bristles do not fall back onto your kitchen floor the next time you sweep.
Stage 3: The low-angle "Flashlight Grazing Test" (The secret to finding invisible glass)¶
Overhead kitchen ceiling lights make transparent glass splinters on shiny tile, linoleum, or hardwood floors almost impossible to see from standing height.
- Turn off the overhead kitchen lights and close the window blinds if possible.
- Lay a bright LED flashlight (or your smartphone flashlight) completely flat against the floor so its beam skims horizontally across the floor surface at a zero-degree grazing angle.
- Any remaining microscopic glass splinter, no matter how tiny or transparent, will catch the horizontal light beam like a prism and cast a long, bright shadow and sparkle across the floor. Sweep the beam in a 360-degree circle from several spots on the floor and across all countertops to pinpoint every hidden splinter.
Stage 4: Micro-splinter pickup using damp paper towels, duct tape, or soft bread¶
- Fold 3 or 4 sheets of thick paper towels into a thick pad, dampen them under the faucet and wring them out until barely damp, and press (do not wipe side-to-side) over the entire floor and countertop surface, throwing each damp pad into your cardboard disposal box after a few presses.
- Wrap wide duct tape or painter's masking tape sticky-side-out around a rolling lint roller or a cardboard tube, or press a slice of fresh, soft white sandwich bread or a cut raw potato flat onto areas where tiny glass dust settled; the spongy gluten of soft bread or the flesh of a raw potato traps microscopic glass needles safely without cutting your fingers.
- Only after completing all four stages should you use a rigid canister shop vacuum (wet/dry vac) to vacuum out deep floor crevices, grout lines, or sliding oven drawer tracks, emptying and rinsing the shop-vac canister and hose immediately afterward.
Special procedure: how to safely remove broken glass from a garbage disposal¶
When a drinking glass or shot glass slips out of wet hands while washing dishes and shatters down inside the black rubber splash baffle of a sink garbage disposal (waste disposer), never reach your bare fingers down into the drain.
- 1.拔掉水槽下方的處理電源線(或關閉斷路器):即使牆壁開關關閉,拔掉水槽下方的設備插頭也可以確保在您處理排水管時沒有人會意外翻轉處理開關。
- 2.拉出可拆卸的橡膠防濺罩(如果配備):在許多現代處理器上,靈活的黑色橡膠水槽擋板可直接向上拉出排水環,讓您可以使用手電筒清晰地看到研磨室。
- 3.使用長尖嘴鉗或廚房鉗取出大塊:使用長金屬鉗或鉗子取出所有可見的玻璃塊。
- 4.使用濕/乾車間吸塵器吸出中型和小碎片:將濕/乾車間真空吸塵器的硬質塑膠噴嘴插入處理室,以吸出碎紙機外環周圍的小玻璃礫石。
- 5.使用「生馬鈴薯方法」處理頑固的卡住的馬鈴薯條:將一個大的生馬鈴薯切成兩半,然後將平坦的切肉端牢固地壓在未插電的處理機內的底部飛輪板上;剩餘的微小玻璃點嵌入堅硬的馬鈴薯肉中,然後直接取出。
- 6. Test the flywheel rotation manually with the hex wrench before restoring power: Insert a 6-millimeter (¼-inch) Allen hex wrench into the manual unjamming socket located at the very bottom center of the disposal motor housing underneath the sink (or use a wooden broom handle against the upper impellers from above) and rotate the flywheel a full 360 degrees in both directions. If it turns smoothly without any gritty metal-on-glass scraping sound, reinstall the splash guard, plug the unit back in, run a strong stream of cold water, and turn the disposal on while standing back with the sink stopper loosely covering the opening.
Warning
If a glass baking dish shattered inside your oven, wait until the oven is completely cold, disconnect power, and remember to pull out the bottom warming or storage drawer underneath the oven and inspect the rubber perimeter door gasket and door hinge slots. Most ovens have vent slots at the bottom of the oven cavity that drop shattered glass cubes straight down into the lower warming drawer or onto the floor underneath the range.
常見問題¶
If a glass baking dish shatters on one side of my oven, can I still eat the food that was baking in a separate pan on the other rack?
No, unless that second pan was sealed tightly under a solid metal Dutch oven lid or crimped aluminum foil that remained 100 percent intact until after you carried it into another room. When tempered glass shatters inside a closed oven, high-velocity microscopic glass needles bounce off the metal oven walls and oven racks in every direction, and the convection fan or rising hot air currents circulate fine glass dust throughout the entire oven cavity. Food safety agencies (including the USDA Food Safety and Inspection Service and the UK Food Standards Agency) classify any open food exposed to a glass break inside an enclosed appliance as physically adulterated and unsafe for consumption.
Can I keep cooking on the three intact burners of my smooth glass-ceramic stovetop if only one corner or one burner has a hairline crack?
No, appliance safety standards and electrical codes strongly warn against using any burner on a cracked glass-ceramic cooktop (whether radiant electric or induction). First, the glass-ceramic panel is subjected to uneven thermal expansion whenever any single burner heats up, which causes a small hairline crack in one corner to suddenly propagate across the entire stove while you have boiling pots on top of it. Second, if a pot boils over or you wipe the stove with a wet sponge, conductive liquid seeps through the capillary crack directly onto the uninsulated 240-volt heating ribbons or high-voltage induction inverter boards underneath, creating an immediate risk of lethal electrical shock through your metal cookware or an internal electrical fire.
How can I tell while shopping or checking my cabinets whether a glass baking dish is borosilicate glass or tempered soda-lime glass?
First, check the stamped markings on the bottom or handles of the dish and the manufacturer's country of origin: in Europe, major glass bakeware brands (such as French-made Pyrex manufactured by International Cookware / Arc, Marinex borosilicate lines, and Simax) still manufacture clear oven bakeware from **borosilicate glass** (and explicitly label their packaging "100% Borosilicate Glass"). In the United States, by contrast, most mass-market clear and tinted consumer glass bakeware sold under major retail brands since the late 1990s is made from **heat-tempered soda-lime glass**. You can also often tell by the edge tint when looking directly into the rim of a clear dish under white light: soda-lime glass typically exhibits a noticeable **bluish-green tint** along the thick cut edge due to iron oxide content, whereas pure borosilicate glass looks almost completely crystal-clear or faintly yellowish-gray along the edge.
What is the safest way to remove a tiny, invisible glass splinter stuck in my finger or the bottom of my foot?
First, do not squeeze or pinch the skin around a glass splinter like a pimple; squeezing breaks the brittle glass needle into smaller pieces under the skin and drives it deeper into the dermis. Wash the area gently with soap and water and pat dry without rubbing. Shine a bright LED flashlight sideways against the skin and use a magnifying glass to see the exact angle at which the splinter entered. If the tip of the glass is protruding above the skin, grip it with sterilized fine-point tweezers and pull it out at the **exact same angle it entered**. If the tiny splinter is flush with the skin, soak the foot or finger in warm water with a tablespoon of Epsom salts or baking soda for 15 minutes to soften the epidermis, or apply a piece of heavy duct tape over the spot and peel it back gently in the opposite direction of entry. If the glass splinter is deep in the weight-bearing heel or ball of the foot, causes sharp pain when walking, or shows any redness or swelling, have a physician or urgent care clinician remove it under local numbing and magnification.
What should I do if a glass thermometer breaks in the kitchen?
First, check the color of the liquid inside the broken thermometer: almost all modern kitchen candy, meat, and oven thermometers sold in the last two decades are filled with **red, blue, or green non-toxic alcohol, organic spirit, or food-grade petroleum distillate**, which you can clean up just like standard broken glass and discard any contacted food. However, if it is a vintage antique thermometer containing **silvery-gray liquid that rolls around in shiny metallic beads**, that liquid is **elemental mercury**. If a mercury thermometer breaks: never vacuum or sweep it (which vaporizes toxic mercury into the air), open windows to ventilate the room, turn off central heating/cooling fans, use stiff index cards or an eyedropper to gather the silver beads onto damp paper towels, seal everything inside a glass jar or double zip-top bags, and contact your local municipal hazardous waste authority or health department for mercury disposal instructions.
Can I put broken glass baking dishes, drinking glasses, or glass cooktop panels into my curbside glass recycling bin?
No, never put broken cookware glass (neither borosilicate nor tempered soda-lime bakeware), glass-ceramic stovetops, drinking glasses, window panes, or mirrors into your household curbside glass recycling bin. Curbside recycling facilities are engineered exclusively for standard container glass (beverage bottles and food jars) that melts at a uniform temperature around 1,400 to 1,500 degrees Celsius. Heat-resistant cookware glass and glass-ceramic stove tops have much higher melting points and different chemical expansion coefficients; even a single broken baking dish mixed into a ton of recycled bottle glass fails to melt completely in the furnace, creating weak structural inclusions ("stones") that ruin thousands of newly manufactured glass bottles. Always wrap broken cookware glass inside sealed cardboard and place it in the regular municipal solid waste trash.
