Deep dive 1: Complete Hydrofluoric Acid (\(HF\)) Rescue Protocol (Home to ICU)¶

Because household rust stain removers (sold in small plastic squeeze bottles in supermarket laundry aisles at 6% to 12% Hydrofluoric Acid) and automotive aluminum/magnesium wheel cleaners rarely print "HYDROFLUORIC ACID" in giant letters on the front label, thousands of homeowners and detailers suffer severe finger and hand burns every year without realizing they have touched one of the most dangerous chemicals on earth.

Step 1: Immediate Homemade Calcium Gluconate Gel Recipe¶

Every workplace that uses \(HF\) is required to keep unexpired tubes of 2.5 percent Calcium Gluconate Gel next to the sink. If a rust-remover or wheel-cleaner exposure happens at home where commercial calcium gluconate gel is unavailable:

1. Flush under cool running tap water for 5 to 15 minutes while a family member calls 911 / 112 / 999 and Poison Control (1-800-222-1222 in the US).
2. Mix an emergency Calcium Carbonate Slurry/Gel in 60 seconds:
3. Take 10 regular-strength (500 mg to 1,000 mg) Calcium Carbonate antacid tablets (such as Tums or Rolaids).
4. Crush them between two spoons or inside a clean plastic bag with a rolling pin into a fine powder.
5. Mix the powder thoroughly with 30 milliliters (2 tablespoons / 1 ounce) of a water-soluble gel (such as K-Y Jelly, plain water-based aloe vera gel, or 1 to 2 tablespoons of tap water) to create a thick paste. (Never use petroleum jelly / Vaseline, because oil-based ointments trap fluoride ions and block water-soluble calcium ions from entering the skin).
6. Use the "Nitrile Glove Poultice" technique for finger and hand burns:
7. Put a nitrile glove on your own hand and massage the calcium gel into the burned area continuously.
8. Kana misapi to diboko ya muntu yina bo me fwa me yoka tiya, fulusa gant ya nitrile ya nene mingi ti nzungu ya nene ya Gel ya Gluconate de Calcium (to gel na nge ya Tums yina bo me niata) mpi kotisa diboko ya muntu yina bo me fwa tiya na kati ya gant yina me fuluka ti gel. Dyambu yai kesalaka nde konso milimetre-kare ya misapi kuvanda ya kuyobila na ba ion ya calcium na ntangu ya ambulance kekwenda na lupitalu.

If your shins or knees look dark purple, bluish-black, white/leathery, or blistered that evening after working with concrete, go to a hospital burn unit immediately: concrete burns are almost always deep full-thickness (third-degree) chemical burns that require surgical excision and skin grafting.

Kudindisa na Mudindu 3: Kubwa na Meso ya Kimunganga: Nsiku ya Kulosila Masa na Minuta 30 tii na 60¶

A splash of drain cleaner, oven cleaner, ammonia, lime, wet cement, bleach, or battery acid into the eye is a true ocular emergency where what you do in the first 10 seconds determines whether the person will be blind for life (see our dedicated eye injuries guide for full details).

• Start flushing with water within 10 seconds: do NOT wait to go to the hospital first: An alkali splash (lye, ammonia, lime, drain opener) penetrates completely through the human cornea into the anterior chamber of the eye in less than 15 to 60 seconds, destroying the corneal limbal stem cells, melting the stroma, and blinding the eye before an ambulance could ever arrive.
• Mutindu ya kulosila disu masa na nzo to na kisalu:
• Remove contact lenses immediately as you begin flushing (contact lenses trap concentrated acid or alkali directly against the cornea).
• Hold the eyelids wide open with your fingers (because severe pain triggers involuntary blepharospasm that clamps the eyelids shut) and direct a gentle, continuous stream of lukewarm tap water, bottled water, or sterile normal saline from the inner corner of the eye (next to the bridge of the nose) outward so contaminated water does not wash into the uninjured eye.
• Flush for a minimum of 30 to 60 continuous minutes for any alkali, cement, lime, or hydrofluoric acid splash (and at least 15 to 30 minutes for acids/bleach).
• Check beneath the upper and lower eyelids (fornices) for trapped lime or cement grit: In plaster, mortar, or dry lime splashes, tiny white chunks of calcium hydroxide lodge deep under the upper eyelid and continue dissolving the eye even after 30 minutes of flushing until a physician flips (everts) the upper eyelid and sweeps the fornices clean with a moistened cotton swab while checking the tear film pH with litmus paper until it stays neutral at pH 7.0 to 7.4.
