Emergency numbers differ by country. This page uses 911, the number for the United States and Canada. Many other countries use 112, 999, or another number. Find the number for your country.

Ngengozi ukushiya i-skillet ye-nonstick engenanto kwi-burner eshushu, ukubilisa imbiza yome ngokupheleleyo, okanye ukutshisa i-pan ye-iron enongwe kwi-oven inokugcwalisa ikhaya nge-acrid, umsi ocaphukisayo ngaphantsi kwemizuzu emi-3. Ngelixa ukutya okutshisayo okanye i-oyile yokupheka yenza i-carbon soot ebonakalayo kunye nomphunga we-acrolein ocaphukisa amehlo kunye nomqala, ukufudumala i-polytetrafluoroethylene (PTFE)* i-nonstick coating (eyaziwa kakhulu ngamagama e-brand afana ne-Teflon, i-SilverStone, okanye i-Fluon) ngaphezu kwe-260 ukuya kwi-350 ukuya ku-350 ukuya ku-350 ukuya ku-260 ukuya ku-260 ukuya ku-350 degrees celsius 200 ℃ ukubola kwe-thermal (* pyrolysis **). Oku kuqhekeka kweekhemikhali okungabonakaliyo kukhupha umxube ontsonkothileyo weegesi ezigqunywe ngumbane kunye namasuntswana epolymer e-ultrafine ngqo kumoya wakho wangaphakathi.

Ebantwini, ukuphefumla umsi oxineneyo osuka kwipani ye-PTFE eshushu kakhulu kubangela isigulo esiqatha, esifana nomkhuhlane ekuthiwa yi polymer fume fever (eyaziwa ngokwembali yi "Teflon flu"), ebonakala ngokungcangcazela ngequbuliso, umkhuhlane, ukuxinana kwesifuba, kunye nokhohlokhohlo olomileyo olubonakala kwiiyure ezi-4 ukuya kwezisi-8 emva kokuba sesichengeni. Nangona kunjalo, ukuba unayo ** iintaka ezifuywayo ** (ii-parakeets, i-cockatiels, i-parrots, i-canaries, i-finches, okanye i-indoor backyard amantshontsho) naphi na ngaphakathi kwekhaya, i-PTFE pyrolysis fumes yi- **ngoko, ithule, i-100 yeepesenti ebulalayo kaxakeka ye-avian ** ebangela ukufa kwe-pulmonary hemorrhage phantsi kwemizuzu, namagumbi angenako ukuvumba ngaphakathi kwemizuzu.

Yenza oku ngoku

  1. Bamba umoya wakho, cima isitshisi sesitovu okanye i-oveni, kwaye utshintshe isitshizi sesitovu okanye i-oveni yoluhlu, kwaye utshintshe i-hood yokukhupha ifeni ukuya OKUPHAKAMILEYO (kuphela ukuba iyaphuma ngaphandle): Ngena ekhitshini ngelixa ubambe umoya wakho, Cima iqhosha lesitshisi, kwaye uvule ihood yoluhlu olungaphezulu **kuphela ukuba uyayazi ukuba iphumela ngaphandle ngombhobho ** iigesi ze-fluoropolymer kwaye uzivuthele nje ngeenxa zonke kwigumbi).
  2. UNGAZE ugalele amanzi abandayo kwipani etshisayo neshushu eyomileyo: Ukugalela amanzi kwi-350-degree-Celsius (662-degree-Fahrenheit) ialuminiyam eyomileyo, intsimbi engatyiwayo, okanye ipani yentsimbi ibangela ugqabhuko-dubulo lomphunga oluthi luqhume amanzi abilayo kunye nomphunga oyityhefu ebusweni bakho, ikrole intsimbi okanye ikrazule iglasi ngokukhawuleza. okanye i-cooktop yokufundisa.
  3. Zikhuphe zonke iintaka ezifuywayo ziye kumoya omtsha wangaphandle ngaphakathi kwemizuzwana engama-60: Ukuba unayo nayiphi na intaka esilo-qabane, musa ukulinda ukuba kuphume umoya endlwini. Bamba intaka (okanye ikheji yonke) kwaye uyisuse ngokupheleleyo ngaphandle kwendlu (okanye ungene kwimoto efudunyezwe ngaphambili okanye kwindlu yommelwane) kwangoko. Nokuba yimizuzu emi-2 yokuvezwa kumsi we-PTFE ongabonakaliyo ubulala iintaka phambi kokuba abantu baqaphele ivumba.
  4. **Yithwale ipani yokutshayela ngaphandle usebenzisa i-oveni eshinyeneyo eyomileyo KUPHELA ukuba akukho madangatye avulekileyo kwaye nendlela yakho icacile **: Ukuba ipani iyatshaya nje okanye ikhazimla ngaphandle kwamadangatye avulekileyo, bamba umqheba nge-oven eyomileyo, enzima okanye yesikhumba, bamba ipani ngobude bengalo ngaphantsi kwesinqe, uyibeke kude nomnyango, i-silicone okanye i-silicone ngaphandle komnyango. off-gassing ngaphandle. Ukuba kushushu kakhulu ukuba ungaphathwa ngokukhuselekileyo, yishiye kwisitshisi esicinyiweyo kwaye uvale ucango lwasekhitshini emva kwakho.
  5. Yenza isantya esiphezulu somoya onqamlezileyo kwaye ushiye ikhaya kangangemizuzu engama-30 ukuya kwengama-60: Vula iifestile kunye neengcango zangaphandle kumacala ahlukeneyo ekhitshini nendlu, beka ifeni yebhokisi efestileni yasekhitshini ** ekhomba ngaphandle ** ukutsala umoya ongcolileyo ngaphandle kwesakhiwo, kwaye uthathe onke amalungu osapho, iintsana, kunye nezilwanyana ezifuywayo ngaphandle emoyeni omtsha de ivumba elimnandi licace.
  6. Fowunela uLawulo lwetyhefu okanye iinkonzo ezingxamisekileyo ukuba nabani na uba nokuphefumla nzima, ukutswina, okanye ukugodola okulibazisekayo kunye nomkhuhlane: EUnited States, tsalela umnxeba kuLawulo lwePoison kwa 1-800-222-1222. Ukuba nabani na onesifo sombefu, iCOPD, okanye isifo sentliziyo uba nokuphefumla, ukukhohlela okuzingileyo, okanye amanqanaba asezantsi eoksijini, okanye ukuba nabani na unengxaki yokuphefumla kakhulu, fowunela inombolo yakho yexesha likaxakeka (911 e-US naseCanada, 112 e-EU, 999 e-UK; bona amanani kaxakeka).

Imithombo efihlakeleyo ye-PTFE iqhuma ngaphandle kweepani zokuqhotsa

Amakhaya amaninzi afumana ukuvezwa komsi wepolymer okanye ukufa kweentaka zezilwanyana zasekhaya ngesiquphe ngaphandle kokuchukumisa ipani yokuqhotsa kuba i-PTFE kunye ne-fluoropolymers ezinxulumene nazo zisetyenziswa njengezikhuselo ezishushu zobushushu obuphezulu ngaphakathi kwezixhobo ezininzi eziqhelekileyo zasekhaya:

  • Ii-oveni ezizicoca ngokwazo kunye nezinto ezintsha zokubhaka kwi-oveni: Ukuqhuba ubushushu obuphezulu umjikelo wokuzicoca (425 ukuya ku-480 degrees Celsius / 800 ukuya kuma-900 degrees Fahrenheit) okanye ukufudumeza i-oveni entsha kraca okokuqala kunokutshiza iidriphu ezigqunywe yi-PTFE, iipani zokuthontsiza ezigqunywe yi-PTFE, iipani ezidityanisiweyo zangaphakathi.
  • Iziqhoyi zomoya, ii-oveni zetoaster, izicinezelo zePanini, kunye nee-ayini ze-waffle: Ukushiya ibhaskithi engenanto ye-air fryer okanye i-oven yetoaster ebaleka kwi-broil okanye ifudumeza ngaphezulu kwama-260 degrees celcius (500 degrees Fahrenheit).
  • Izifudumezi zendawo, izomisi-enwele, ii-ayini zokuphotha, kunye neeayini zempahla: Izifudumezi ezininzi ze-ceramic space, izigqubuthelo zebhodi yoku-ayina, kunye nee-soleplates kwii-ayini zomphunga zisebenzisa iingubo ze-PTFE eziphuma ngerhasi xa zishiywe zijike zijonge phantsi okanye ngexesha lokutshiswa kwemizi-mveliso yokuqala.
  • Izibane zobushushu "ezigqunywe" ezikwaziyo ukuqhawuka kunye neebhalbhu zebrooder: Izibane zobushushu eziqhelekileyo ze-infrared ezithengiswa zigqunywe ngokhuselo lwe-PTFE ukunqanda ukuqhekeka kweglasi ziya kukhupha igesi ebulalayo ye-fluoropolymer ngephanyazo xa ibhalbhu itshisa, kucinywa rhoqo imihlambi yamantshontsho angasemva kwendlu okanye izirhubuluzi ezingaphakathi/iintaka ezingaphakathi.

Icandelo 2: I-Polymer Fume Fever ("Teflon Flu") ebantwini: iimpawu kunye nonyango

Ukuba uphefumlele umsi okanye umsi ongabonakaliyo ngelixa uhlangula ipani eshushu eshushu kakhulu kwisitovu, unokuziva uphilile ngokupheleleyo kwiiyure ezi-2 ukuya kwezi-3 zokuqala, kodwa ubethwe ngequbuliso ngobo busuku yinto evakala ngathi sisifo esiqatha somkhuhlane.

Umgca wexesha eliqhelekileyo kunye neprofayili yeempawu

I-Polymer fume fever yimpendulo yokudumba ebukhali, ekwaziyo ukuzikhawulela eyenzeka xa amasuntswana e-ultrafine efluoropolymer (encinci kune-0.1 microns) edlula imingxuma ephezulu yempumlo aze afake nzulu ngaphakathi kwi-alveoli yemiphunga (iingxowa zomoya zemiphunga), ebangela i-alveolar macrophages ye-macrophages ye-inflammatory tome cytome tome. umkhuhlane** kwiiwelda ezivezwe kwi-zinc oxide):

  1. Ixesha elifihlakeleyo (iiyure ezi-0 ukuya kwezi-4 emva kokuba sesichengeni): Kwakamsinyane nje emva kokusezela umsi, unokuqaphela kuphela ubushushu obuphakathi, okwexeshana okanye ukukrwela emqaleni, incasa encinci yesinyithi okanye yekhemikhali emlonyeni, okanye ukucaphuka kancinci kwamehlo.
  2. I-Acute Acute (iiyure ezi-4 ukuya kwezi-8 emva kokuba sesichengeni): Ngequbuliso, phakathi kweeyure ezi-4 nezi-8 emva kwesehlo sasekhitshini (esidla ngokuvusa umntu ebusuku), iimpawu zenkqubo zihlasela ngequbuliso:
  3. Umkhuhlane ophezulu: Ngokuqhelekileyo 38.0 ukuya kuma-39.5 degrees celcius (100.4 ukuya ku-103.1 degrees Fahrenheit).
  4. Iingqele eziqhaqhazelis' amazinyo (iingqele), ukubila okubandayo, kunye nokuqaqamba kwamalungu ngokubanzi (myalgias kunye arthralgias).
  5. Intloko ebuhlungu yangaphambili, ukudinwa, kunye nesicaphucaphu esingephi ngamaxesha athile.
  6. Ukhohlokhohlo olomileyo, olungavelisi mveliso kunye nokuziva ukuqina kwesifuba okanye ukuphefumla kancinci xa uphefumlela phezulu.
  7. Isigaba seSigqibo (iiyure ezingama-24 ukuya kwiiyure ezingama-48 emva kokuba sesichengeni): Kubantu abadala abasempilweni ngaphandle kwesifo semiphunga esisisiseko, i-polymer fume fever ephakathi izisombulula ngokwayo ngaphakathi 12 kwiiyure ezingama-48 emva kokuba umntu esusiwe emoyeni ongcolileyo, engashiyi umonakalo osisigxina wemiphunga.

Ukhathalelo lwasekhaya vs ixesha lokuya kwigumbi likaxakeka

  • Yintoni omawuyenze ekhaya kwiPolymer Fume Fever ephakathi ukuya kwephakathi:
  • Fowunela ingingqi yakho Iziko lokuLawula ityhefu (1-800-222-1222 eUnited States; 111 eUnited Kingdom; 1-844-POISON-X eKhanada; 13 11 26 eOstreliya) ukuloga ukuvezwa kunye nokufumana iingcebiso ezilungiselelwe iliso leklinikhi.
  • Phumla kwindawo engena umoya ngokupheleleyo, engenamsi kwaye usele amanzi amaninzi okanye ulwelo lwe-electrolyte ukuze ubuyisele ulwelo olulahlekileyo ngenxa yomkhuhlane kunye nokubila.
  • Izinciphisi zefiva eziqhelekileyo (acetaminophen/paracetamol okanye ibuprofen, ezithathwe ngokwemiyalelo yephakheji ukuba zikhuselekile ngokwezonyango kuwe) zinceda ukuthomalalisa umkhuhlane, ukugodola okungcangcazelayo, kunye nentloko ngelixa ukudumba kwe-cytokine kuncipha. Qaphela ukuba amayeza okubulala iintsholongwane awayincedi i-polymer fume fever ngenxa yokuba kukudumba kweekhemikhali ezinyumba, hayi usulelo lwebhaktiriya.
  • Ulufuna nini ukhathalelo lweSebe likaxakeka:
  • ungacingi ukuba iimpawu ziyi-benign polymer fume fever ukuba ipani ishiywe ivutha kumaqondo obushushu agqithisileyo (ngaphezu kwe-400 ° C / 750 ° F) kangangemizuzu eyi-10 ukuya kuma-30+ (umzekelo, ngelixa umntu elele okanye ephumile endlwini), njengoko ipyrolysis egqithisileyo ivelisa perfluoroisobutylene (PFIB) kunye nenedelai-hydrogen ne-hydrogen fluorode i-non-cardiogenic pulmonary edema (ulwelo olugcwalisa imiphunga).
  • Yiya kwiSebe lezoNgxamiseko elikufutshane ngokukhawuleza ukuba umntu obhencekileyo une-asthma, COPD, heart failure, ukhulelwe, okanye ulusana/umntwana omncinci*, okanye ukuba nabani na ukhula:
    1. ** Ukuphefumula okufutshane ekuphumleni **, ukuphefumla ngokukhawuleza, okanye i-pulse oximeter yokufunda ngezantsi ** 94 ukuya kwi-95 ekhulwini **.
    2. Ukutswina okuvakalayo, ukuqhekeka/ukugquma kwezandi esifubeni, okanye ukukhohlela okunamagwebu okanye isikhohlela esipinki.
    3. Iintlungu ezimandundu esifubeni, isiyezi, okanye ukubhideka.
    4. Iimpawu ezithi ** ziba mandundu emva kweeyure ezingama-24 ** okanye zisilele ukusombulula emva kweeyure ezingama-48.

Kuthekani ukuba umntu ngempazamo uginya amadlelo aqinileyo etyabeka exobuliweyo?

Abantu abaninzi bayoyika xa bebona iiflakes ezimnyama zeTeflon ekrweliweyo ixobula ipani endala emaqandeni okanye isuphu, besoyika ukuba igalelwe ityhefu. Ukuginya okuqinileyo, iiflakes ezingatshisiyo zePTFE AKUKHO tyhefu. I-PTFE eSolid ingena kwibhayoloji nakwikhemikhali kumjelo wesisu; iasidi yesisu ayinakukwazi ukuyinyibilika, amathumbu akho akakwazi ukuyifunxa, kwaye amasuntswana aqinileyo asuka adlule ngokungenabungozi kwinkqubo yakho yokwetyisa ukuya esitulweni. Ingozi engxamisekileyo evela kwi-PTFE iza **i-100 yeepesenti ekusezeleni iigesi ezishushu kunye nomsi we-ultrafine ** owenziwe xa ipani eyomileyo ishushu ngaphezu kwe-260 ° C (500 ° F). Nangona kunjalo, xa i-pan ye-nonstick ikrweliwe, i-blistered, okanye yomile ngokugqithisileyo, ** yilahle i-pan ngoko nangoko **, kuba i-polymer matrix eyonakeleyo iya kukhupha igesi kumaqondo aphantsi ngexesha lokusetyenziswa kwixesha elizayo.

Icandelo 3: Ityhefu Yentaka Yezilwanyana ("Teflon Toxicosis"): Kutheni imizuzwana ibalulekile

Ngelixa abantu benemiphunga efana nesac engaboniyo (i-alveoli) apho kuphela iqhezu lomoya elitshintshwayo ngokuphefumla ngakunye, iintaka zineyona nkqubo isebenzayo yokuphefumla yayo nayiphi na i-vertebrate eMhlabeni: imiphunga eqinileyo eqhagamshelwe kwiingxowa zomoya ezilithoba ezinodonga olucekethekileyo ezityhala umoya ngokungangqalanga kwiicapillaries zegazi ezincinci (parabronchi). Oku kuvumela iintaka ukuba zikhuphe i-oksijini kwiindawo eziphakamileyo, kwaye zibangela ukuba zifunxe i-toxins emoyeni ku-*-10 ukuya ku-20 kumaxesha omntu **.

Kutheni umsi we-PTFE ubulala iintaka kumagumbi akude nekhitshi

Xa i-PTFE pan eshushu kakhulu ikhupha amasuntswana e-ultrafine fluoropolymer kunye neegesi ezineasidi, loo masuntswana atshabalalisa ngoko nangoko i-single-cell capillary membranes ngaphakathi kwimiphunga yentaka, ibangele imiphunga yentaka izalise ngokukhawuleza igazi (acute congestive pulmonary hemorrhage).

  • Iintaka ziyafa ngaphambi kokuba abantu banukise nantoni na: Ngenxa yokuba i-PTFE iqalisa ukukhupha amasuntswana e-ultrafine kwi-260°C (500°F), ngaphambi kokuba umsi obonakalayo okanye ivumba elitshisayo likhule, izikhwenene, iicockatiels, iiparakeets (i-budgies), kunye neentaka ezigcinwe kwigumbi lokulala okanye kwiofisi ephezulu zidla ngokuwa phantsi ekhitshini ngaphambi kokuba umntu lowo abe ekhitshini.
  • Iimpawu ze-PTFE toxicosis kwiintaka:
  • Ukuphefumla ngomlomo ovulekileyo, ukukhefuzela, okanye isingqisho ukunqunqa umsila ngawo wonke umphefumlo.
  • Ukubamba amaphiko kancinci ngaphandle komzimba, ubuthathaka obugqithisileyo, ukushukuma, okanye ukuwa phantsi kwekheji.
  • Ukucofa okuvakalayo, ukutswina, okanye ukugungqa izandi zokuphefumla; igazi okanye ulwelo olupinki olujikeleze iimpumlo (nares) okanye umlomo; ukuxhuzula ngokukhawuleza nokufa ngesiquphe.
  • Amanyathelo okuhlangula iintaka ezingxamisekileyo:
  • **Susa intaka emoyeni omtsha wangaphandle ngokukhawuleza **: Yonke isekhondi ngaphakathi kwendlu yongeza kwidosi ebulalayo. Yithwale intaka ngaphandle (ikhuseleke emoyeni/engqeleni kwisithwala okanye itawuli, okanye ngaphakathi kwisithuthi esifudunyezwe kwangaphambili ebusika).
  • Gcina intaka izolile, ishushu, kwaye izolile kwinqwelo encinci ephathwayo: Kuba ukuphatha intaka ene-hypoxic kwandisa isidingo sayo se-oksijini kwaye kunokubangela ukubanjwa kwentliziyo ebulalayo, musa ukuyibamba okanye ucinezele intaka.
  • Shenxela ngoko nangoko kuGqirha wezilwanyana weNtaka engxamisekileyo: Biza ngaphambili usendleleni ukuze iqela lonyango lwezilwanyana lizalise kwangaphambili igumbi le-oksijini elishushu, elifumileyo le-100% ye-oksijini (i-incubator) kwaye lilungiselele i-diuretics engxamisekileyo (i-furosemide), i-bronchodilators, kunye namayeza okulwa nokudumba. Musa ukuyibuyisela intaka ngaphakathi kwikhaya lakho ubuncinane 6 ukuya kwiiyure ezili-12 zomoya ovuthuzayo.

How to handle a smoking Cast Iron skillet or boiled-dry Stainless Steel pot safely

  1. Recognize Acrolein irritation: When the polymerized oil seasoning on a cast iron or carbon steel pan burns off into thick white-gray smoke, the sharp, tear-inducing chemical that stings your eyes and makes you cough immediately is acrolein (propenal), formed by the thermal dehydration of glycerol in fats. Acrolein is a potent mucous membrane and asthma irritant (and burning organic matter also releases carbon monoxide), so you must still open windows, run an exhaust fan, and step into fresh air until the smoke clears.
  2. Prevent Thermal Shock and Metal Explosions:
  3. Cast iron is brittle under thermal shock: If you put a 370-degree-Celsius (700-degree-Fahrenheit) cast iron skillet under the kitchen faucet or pour water into it, the cooled section contracts instantly while the surrounding iron remains expanded, causing the heavy iron skillet to crack in half with a loud gunshot bang while spraying scalding steam.
  4. Leave the pan on the turned-off burner for 45 to 60 minutes until it is cool to the touch. If the pan is smoking so heavily that it is triggering hardwired smoke alarms throughout the building, use two thick dry leather welding gloves or heavy dry silicone mitts to carry it outdoors and set it on dry concrete, bricks, or dirt (never on a wooden deck, vinyl siding, synthetic outdoor rug, or wet grass).
  5. Removing smoke odor from your kitchen after the incident:
  6. Once the pan is outside and the air has cleared for 60 minutes, wash the range hood grease filters in hot soapy water (toxic particles and acrolein cling to greasy mesh filters), wipe down surrounding kitchen cabinets and countertops with warm water and dish soap, and replace your HVAC furnace filter if the central air fan was running during the smoke event.

Why you must never use a damp towel or wet potholder to move an overheated pan

At 300 to 400 degrees Celsius (572 to 752 degrees Fahrenheit), the metal handle of a skillet is far hotter than a normal oven bake. If you grab that handle with a slightly damp dish towel or wet cloth potholder, the moisture inside the fabric flashes into superheated 100°C+ (212°F+) steam in a fraction of a second, shooting straight through the weave of the towel and causing an instant second- or third-degree steam burn across your palm, forcing you to drop the scorching pan onto your feet or floor. Only use bone-dry, thick silicone or heavy insulated oven mitts.

Frequently asked questions

How can I tell if my nonstick pan contains PTFE (Teflon) versus a PTFE-free ceramic coating?

Traditional PTFE nonstick pans almost always have a matte charcoal-black, dark gray, or speckled bronze interior surface and are marketed as "classic nonstick", "hard-anodized nonstick", or branded with names like Teflon, Autograph, Platinum, or Granitium. In contrast, PTFE-free ceramic nonstick pans use a silica (sand-derived) sol-gel coating that typically has a glossy, smooth enamel-like finish (often in white, cream, light blue, sage green, or glossy gray) and explicitly state "PFAS-Free / PTFE-Free / PFOA-Free Ceramic" on the box or bottom stamp. When in doubt during an overheating incident, always treat any unidentified nonstick pan as PTFE and ventilate immediately.

Does "PFOA-Free" on a pan label mean it is "Teflon-Free" and safe to overheat around birds?

No, this is the single most common and dangerous misconception in cookware labeling. PFOA (perfluorooctanoic acid) was a chemical processing aid phased out of manufacturing by 2015, whereas PTFE (polytetrafluoroethylene) is the actual nonstick fluoropolymer plastic coating itself. Almost every PTFE Teflon pan sold today is proudly labeled "100% PFOA-Free", yet it is still 100 percent PTFE and will still release toxic polymer fumes that cause Polymer Fume Fever in humans and rapid death in pet birds if overheated above 260°C (500°F). Only cookware labeled "PTFE-Free and PFAS-Free" (or bare stainless steel, cast iron, carbon steel, and enameled cast iron) is free of fluoropolymers.

If I overheated my nonstick pan dry for 5 minutes and it smoked, is the pan still safe to cook with after it cools down?

No. Once a PTFE nonstick pan has been overheated dry to the point of smoking, blistering, browning, or warping, the molecular fluoropolymer chains have thermally fractured and degraded. Even if the pan looks mostly intact after washing, a thermally degraded PTFE coating will break down, flake, and release fumes at much lower cooking temperatures the next time you use it. Let the pan cool completely and throw it in the trash.

Are dogs, cats, or human babies harmed by overheated nonstick pan fumes the way pet birds are?

Mammals, including dogs, cats, and human infants, do not have the rigid unidirectional air-sac lung anatomy of birds, so they are vastly more resistant to sudden death from brief low-level exposure than parrots or finches. However, infants, small children, cats (which are prone to feline asthma), and small or flat-faced (brachycephalic) dogs have small airways and high respiratory rates relative to body weight. Heavy PTFE pyrolysis smoke can cause acute airway irritation, coughing, vomiting, or chemical pneumonitis in pets and children. Always evacuate babies, children, dogs, and cats to fresh outdoor air right alongside yourself while the house ventilates for 30 to 60 minutes.

Can I eat food that was in another pot on the stove or sitting on the kitchen counter when a PTFE pan overheated and smoked?

Throw away any uncovered food that was sitting on the stove or nearby kitchen counters during a heavy PTFE pyrolysis smoke event. Ultrafine fluoropolymer particles and acidic condensation products settle out of the plume onto exposed moist food surfaces. Sealed food inside closed containers, refrigerators, or cabinets is completely unaffected.

What should I do if a boiled-dry pot melted its aluminum bottom onto my glass-ceramic electric stove top?

Turn the burner knob OFF immediately, step back, and let the pot and glass cooktop cool completely to room temperature for at least 1 to 2 hours, never pour water on it and never try to pry a red-hot melted aluminum base off glass, or the molten metal will fuse permanently into the glass pores and pull chunks of glass out as it cools. If the cooled pot is fused to the glass-ceramic surface, the glass cooktop surface is structurally compromised and can shatter violently the next time it heats; disconnect the range breaker and have an appliance technician replace the glass top panel.
