Ledakan kembang api, cedera ledakan tangan, dan pembuangan barang tak berguna¶

Consumer and commercial pyrotechnics combine flash-powder high explosives, aerial propellants, heavy metal colorants, and white-hot metallic sparks into handheld cardboard tubes. Every year during national celebrations and festivals (such as New Year's Eve, Diwali, Lunar New Year, Independence Day on July 4^th, Bastille Day, and Guy Fawkes Night), thousands of adults and children suffer permanent blindness, ruptured eardrums, third-degree facial burns, and catastrophic hand blast amputations. Even seemingly harmless handheld wire sparklers given to toddlers burn using a thermite-like magnesium, aluminum, or iron composition at temperatures between 1,000 and 1,600 degrees Celsius (1,800 and 3,000 degrees Fahrenheit), which is hot enough to melt glass, gold, and aluminum and causes instantaneous full-thickness (third-degree) skin burns on contact.

More severe still are aerial mortar shells, reloadable festival shells, illegal M-80 / quarter-stick salutes, and homemade pipe bombs that detonate prematurely inside a person's grip or directly in front of their face. When a 40-to-75-millimeter (1.5-to-3-inch) aerial shell explodes in a closed hand, the supersonic shockwave and expanding gases hyperextend the thumb and fingers past their structural limits, resulting in the classic "blast hand" injury: thumb and finger amputations, split palm clefts, open metacarpal fractures, and shredded digital arteries. Knowing how to control arterial hand bleeding and preserve severed digits on ice without freezing them, why you must never rub or press on a fireworks eye injury, how to cool white phosphorus and metallic burns, and how to soak misfired "dud" fireworks safely prevents permanent disability and death.

1. Apply direct pressure or a commercial tourniquet immediately for a severe fireworks hand blast injury. Press a thick stack of sterile gauze or a clean cotton towel firmly onto the bleeding hand and elevate the arm above heart level; if bright red blood continues spurting from the wrist or forearm, apply a commercial tourniquet 5 to 7 centimeters (2 to 3 inches) above the wrist or elbow and call your local emergency number (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom) or check nomor darurat.
2. Preserve amputated fingers or thumb segments in damp gauze inside a sealed plastic bag placed on ice water. Never put severed fingers directly onto bare ice or submerge them directly in liquid water, which freezes or swells the microscopic blood vessels and prevents surgical reattachment.
3. Shield a fireworks eye injury with a rigid protective cup (like the bottom of a paper cup) and NEVER rub or apply pressure. Fireworks eye trauma frequently involves a ruptured or perforated eyeball (open globe injury); pressing a bandage against the eye squeezes the internal contents out of the cornea and causes permanent blindness.
4. Cool sparkler and gunpowder thermal burns under cool running tap water for 20 full minutes. Gently brush off dry loose powder first, then hold the burned hand, foot, or face under cool running water (15 degrees Celsius / 59 degrees Fahrenheit) for 20 continuous minutes; never apply ice, butter, toothpaste, or ointments.
5. NEVER walk up to, peek down into, or attempt to relight a misfired "dud" firework. Delayed smoldering inside the fuse channel or black-powder lift charge frequently detonates an aerial mortar shell 5 to 15 minutes after it appears to have gone out, striking anyone leaning over the tube squarely in the face.
6. Wait at least 20 minutes before approaching a misfired firework, then submerge it completely in a bucket of water overnight. Use long-handled tongs or a shovel from the side (never leaning your head over the tube) to drop the dud into a deep 20-liter (5-gallon) bucket of water so the powder core is thoroughly saturated and inert before disposal.

Pyrotechnic hazard matrix: temperatures, blast physics, and injury profiles¶

Understanding the temperatures and explosive yields of different consumer and display fireworks explains why specific injuries occur and how emergency physicians treat them.

Treating catastrophic hand blast injuries and finger amputations¶

The human hand is the most frequently injured body part in fireworks explosions. When a firecracker, mortar shell, or Roman candle explodes while grasped in the palm, the expanding gas bubble forces the thumb radially outward and hyperextends the fingers dorsally while driving carbonaceous soot and cardboard fragments deep into the carpal tunnel and tendon sheaths.

1. Immediate hemorrhage control on a blasted hand¶

1. Apply direct pressure and elevate: Even when multiple fingers are blown off or the palm is split open down to the white metacarpal bones, the majority of hand blast bleeding comes from the superficial and deep palmar arterial arches and digital arteries, which can usually be controlled by firm, continuous direct pressure using a thick stack of sterile gauze pads or a clean folded cotton towel held tightly over the entire hand while elevating the arm above the level of the heart.
2. When to use a commercial tourniquet: If a mortar shell or pipe bomb blast has severed the radial or ulnar artery at the wrist or caused a partial forearm amputation with bright red arterial blood spurting uncontrollably through the pressure dressing, apply a commercial windlass tourniquet 5 to 7 centimeters (2 to 3 inches) above the wrist or above the elbow and tighten until bleeding stops completely; see severe bleeding and tourniquet application.
3. Remove all rings, watches, and bracelets from the injured hand and wrist within the first 2 minutes: Blast and thermal trauma trigger massive fluid swelling (edema) across the hand and fingers within 15 minutes. A gold or titanium wedding band left on a blasted or burned finger turns into an unyielding steel tourniquet that cuts off blood flow and causes gangrenous loss of an otherwise salvageable finger. Slide rings off immediately using soap or cold water, or cut them off with a ring cutter.
4. Never cut off "dangling" fingers or skin flaps: Even if a finger is crushed, pale, and attached only by a thin 3-millimeter strip of skin or a single tendon (subtotal amputation), that tiny bridge often contains a critical dorsal vein or digital nerve that allows a microvascular hand surgeon to save the digit. Gently align the dangling finger in a neutral resting position next to the adjacent fingers, pad between the fingers with moist sterile gauze, and splint the whole hand and wrist on a padded board or rolled magazine.

2. Bagaimana cara mempertahankan ruas jari atau ibu jari yang diamputasi total¶

Ahli bedah tangan mikrovaskuler dapat berhasil menanam kembali (memasang kembali) ibu jari dan jari yang terputus, terutama pada anak-anak dan bila ibu jari atau beberapa jari terlibat, asalkan bagian yang diamputasi tersebut tetap terjaga dengan baik selama pengangkutan:

1. Search the blast site immediately with flashlights to locate all severed finger segments (especially the thumb, which accounts for 40 percent of total hand function).
2. Rinse gently, never scrub: If the severed finger is covered in dirt, grass, or gunpowder soot, rinse it gently for a few seconds with sterile normal saline or clean bottled drinking water. Never scrub the raw tissue with a brush, and never pour hydrogen peroxide, rubbing alcohol, or iodine onto the severed part (which chemically kills the exposed blood vessels and nerves).
3. Use the 3-layer "Damp Gauze -> Sealed Plastic Bag -> Ice Water Bath" method:
4. Layer 1: Wrap the severed finger completely in sterile gauze pads (or a clean paper towel) lightly moistened (damp, not dripping wet) with sterile saline or clean bottled water.
5. Layer 2: Place the wrapped finger inside a clean, watertight zip-top plastic bag, press the excess air out, and seal the zipper tightly. Label the bag with the patient's name and time.
6. Layer 3: Place that sealed plastic bag inside a second larger container, cooler, or outer plastic bag filled with a mixture of crushed ice and cold water (slush bath at roughly 4 degrees Celsius / 39 degrees Fahrenheit).

Ocular fireworks trauma: open globe injuries and corneal burns¶

Approximately 15 to 20 percent of all fireworks injuries strike the eyes, and a third of severe ocular fireworks injuries result in permanent legal blindness or surgical removal of the eye (enucleation). Fireworks injure the eye through three simultaneous mechanisms: blunt blast shockwave contusion (causing bleeding in the front chamber of the eye called hyphema, lens dislocation, and retinal detachment), high-velocity projectile perforation (cardboard plugs, plastic casing shards, or unburnt black-powder grains punching straight through the cornea or sclera), and extreme thermal/alkaline chemical burns from burning metallic sparks.

Step-by-step first aid for a fireworks eye injury¶

1. Recognize the signs of a ruptured or penetrated eyeball (open globe injury):
2. Visible blood pooling inside the colored iris area of the eye (hyphema).
3. A pupil that looks teardrop-shaped, peaked, or irregular instead of round, or brownish/black iris tissue protruding through a tear in the clear cornea.
4. Clear jelly-like fluid (vitreous humor) leaking from the eye, or the front of the eye looking flattened or deflated.
5. Severe eye pain accompanied by an immediate drop in vision (able to see only hand motion or light).
6. Strictly enforce the 4 "NEVERs" of ocular blast trauma:
7. NEVER rub, press on, or squeeze the injured eye. Even the slightest finger pressure on a perforated eyeball extrudes the iris, lens, and retina out through the wound, causing irreversible blindness.
8. NEVER attempt to pull out or tweeze out any cardboard splinter, wire, or firework fragment stuck in the eyeball.
9. NEVER forcefully flush or squirt tap water into an eye that has a suspected puncture, laceration, or blast rupture. (Only gentle saline irrigation is used if the injury is purely superficial dry powder dust on an intact eye without blast impact; when in doubt after a firework blast, do not irrigate; shield and go straight to the emergency room).
10. NEVER put eye drops, ointments, or aspirin in or give aspirin/ibuprofen by mouth (NSAIDs thin the blood and worsen intraocular bleeding/hyphema).
11. Apply a rigid protective eye shield resting on the facial bones:
12. If you do not have a military/medical rigid aluminum Fox eye shield in your first aid kit, take a disposable paper cup or Styrofoam coffee cup, cut the bottom 4 centimeters (1.5 inches) off the cup, and tape that rigid cup bottom over the injured eye so the rim rests entirely on the hard brow bone above and cheekbone below, without touching the eyelids or eyeball at all.
13. A pair of polycarbonate safety glasses or the person's regular eyeglasses worn over the eye also serves as a temporary protective shield.
14. Cover the UNINJURED eye as well (binocular patching):
15. Both human eyes move together synchronously (consensual conjugate eye movement). If the injured eye is covered with a cup but the patient is looking around rapidly with their good eye during the ambulance ride, the injured eyeball underneath the cup is also swiveling back and forth against embedded shrapnel.
16. Lightly cover the uninjured eye with a clean cloth or ask the patient to keep both eyes closed while guiding them by the arm, and keep their head elevated at a 30-to-45-degree angle during transport to an emergency room with an on-call ophthalmologist; see eye injuries.

Sparkler burns, gunpowder flash burns, and acoustic blast trauma¶

1. Cooling sparkler and flash-powder skin burns¶

Because handheld wire sparklers burn using metallic fuels (magnesium, aluminum, iron, or titanium) mixed with oxidizers, they continue burning even if dropped into grass or brushed against clothing, reaching 1,000 to 1,600 degrees Celsius (1,800 to 3,000 degrees Fahrenheit).

1. Extinguish burning clothing immediately: If a sparkler or Roman candle star ignites a child's shirt or synthetic dress, force them to the ground immediately (Stop, Drop, and Roll), smother the flames with a heavy cotton blanket or coat, or douse them with a bucket of water.
2. Brush off dry powder, then flush with cool running water for 20 minutes:
3. Gently brush away any loose dry firework powder or ash from the skin.
4. Immediately place the burned hand, foot, or face under cool running tap water (approximately 15 degrees Celsius / 59 degrees Fahrenheit) for a full 20 continuous minutes.
5. Why if white/yellow phosphorus is involved: In tropical and Latin American regions where illegal crackers contain white or yellow phosphorus, particles embedded in the skin emit white smoke with a garlic odor and spontaneously reignite whenever exposed to air. Keep the burned area continuously submerged in cool water or covered with dripping-wet saline gauze during transport so atmospheric oxygen cannot reach the phosphorus particles.
6. Cover loosely with plastic cling wrap: After 20 minutes of water cooling, lay a clean sheet of household plastic food wrap (cling film) loosely over the burn (never wrapped tightly around a limb) to keep air off the raw nerve endings; see burns first aid.

2. Ruptured eardrums (tympanic membrane perforation) from blast overpressure¶

Tembakan kilat atau peluru udara yang meledak dalam jarak 1 hingga 3 meter (3 hingga 10 kaki) dari kepala seseorang akan menghasilkan gelombang tekanan berlebih akustik seketika yang melebihi 170 hingga 190 desibel (35 hingga 100 kilopascal / 5 hingga 15 psi), yang cukup untuk menghancurkan membran timpani (gendang telinga) dan membuat tulang kecil tulang pendengaran telinga tengah terkilir:

• Gejala: Tiba-tiba telinga berdenging (tinnitus), gangguan pendengaran teredam, nyeri telinga yang tajam, pusing/vertigo, dan terkadang tetesan darah merah cerah atau cairan bening mengalir dari saluran telinga.
• Pertolongan pertama: Jangan sekali-kali memasukkan air, obat tetes telinga, minyak, atau kapas ke dalam saluran telinga setelah cedera akibat ledakan, karena memasukkan cairan yang tidak steril melalui gendang telinga yang robek ke dalam rongga telinga tengah dapat menyebabkan infeksi parah. Cukup letakkan kain kasa steril yang longgar dan kering di bagian luar telinga untuk menampung cairan apa pun, instruksikan pasien untuk tidak membuang ingus, dan mintalah dokter telinga, hidung, dan tenggorokan (THT) memeriksa telinga.

3. Keracunan kembang api akibat konsumsi fosfor pada anak¶

Di beberapa bagian Amerika Latin dan Asia Tenggara, petasan gesekan atau perkusi kecil (seringkali berbentuk seperti permen atau tablet kecil berwarna-warni yang disebut diablitos, totes, atau martinicas) dibuat dengan fosfor putih/kuning:

• Sangat mematikan: Menelan bahkan sebagian kecil (1 miligram per kilogram berat badan) fosfor putih menyebabkan nyeri mulut/perut seperti terbakar, muntah-muntah yang berbau seperti bawang putih dan bersinar samar dalam gelap atau mengeluarkan asap putih (emesis bercahaya/merokok), diikuti dengan fase "bebas gejala" selama 24 jam yang menipu sebelum bencana gagal hati akut, gagal ginjal, dan kematian terjadi.
• Tindakan: Jika balita memasukkan kembang api yang belum terbakar atau bekas ke dalam mulutnya, jangan pernah memberikan susu atau makanan berlemak (lemak mempercepat penyerapan fosfor di usus). Bilas mulut mereka dengan air dan segera bawa mereka ke ruang gawat darurat rumah sakit anak; lihat pertolongan pertama keracunan.

Pembuangan kembang api yang "tidak berguna" dan puing-puing yang salah sasaran dengan aman¶

Hampir sepertiga dari semua cedera kepala akibat kembang api yang fatal terjadi ketika orang dewasa menyalakan mortir yang dapat diisi ulang atau kue multi-shot, tidak ada yang terjadi setelah sekringnya terbakar, dan orang tersebut berjalan mendekat dan menyandarkan wajahnya di atas tabung untuk melihat mengapa sekringnya tidak meledak.

Protokol langkah demi langkah untuk menetralisir kembang api yang salah sasaran¶

1. Tetapkan perimeter pengecualian 15 meter (50 kaki) dan mulai pengatur waktu 20 menit: Segera setelah kembang api yang menyala gagal menyala atau berhenti menembak di tengah rangkaiannya, teriaklah kepada semua penonton untuk tetap di belakang dan perhatikan jam selama 20 menit penuh.
2. Douse from a distance first if a garden hose is available: After waiting 20 minutes, if you have a pressurized garden hose, spray water from a safe distance into the top of the misfired cake or tube before walking up to it.
3. Submerge completely in a deep bucket of water from the side:
4. Approach the firework keeping your head and upper body well to the side of the tube's aiming axis (never lean over the top).
5. Using long-handled barbecue tongs or a flat shovel, pick up the misfired firework (or the entire mortar tube if a live shell is stuck inside the bottom) and submerge it completely in a 20-liter (5-gallon) bucket filled to the brim with cold water.
6. Place a brick or stone on top of the floating cardboard firework so it stays 100 percent underwater overnight (for at least 12 to 24 hours). Water penetrates the cardboard casing and dissolves the potassium nitrate oxidizer in black powder, rendering it permanently unable to ignite.
7. Wrap in double plastic bags before placing in outdoor trash:
8. The next morning, remove the waterlogged firework from the bucket, wrap it tightly inside two layers of heavy plastic trash bags so the wet powder cannot dry out in the sun and become flammable again, and place it in your outdoor household solid waste bin (or call your local fire department non-emergency line if it is a large unexploded commercial display shell or illegal salute).
9. Never throw soaked or unexploded fireworks into a campfire, wood stove, or burn barrel, and never dump spent fireworks boxes directly into a plastic trash bin inside your garage on the night of the celebration; smoldering cardboard glue inside "spent" fireworks cakes is a leading cause of midnight house fires hours after the show ends.
