tissues.
May cause hypocalcemia (depletion of calcium in the body)
which may be fatal.
The effects of contact with dilute solutions of hydrofluoric acid
or its vapours may be delayed.
Prolonged contact with very dilute solutions will cause burns.
Eyes : Liquid or vapor causes burns which may be delayed.

which may be fatal.
Inhalation : Mild exposure:
Vapours may be irritating to eyes, nose, throat, and lungs.
Symptoms may be delayed.
Severe exposure:
Corrosive to respiratory system
Causes severe burns.
Inhaled corrosive substances can lead to a toxic oedema of the
lungs.
May cause hypocalcemia (depletion of calcium in the body)
which may be fatal.
Chronic Exposure : The effects of contact with dilute solutions of hydrofluoric acid
or its vapours may be delayed.
Symptoms might include pain, redness of the skin and possible
tissue destruction.
Can cause bone and joint changes in humans (fluorosis).

Tetrahydrothiophene 1,1-dioxide 126-33-0 10.00
SECTION 4. FIRST AID MEASURES
General advice : First aider needs to protect himself. Medical assistance
essential. Remove all contaminated clothing while washing
continuously. After thorough washing the burned area should be
immersed in a solution of 0.1% iced aqueous Benzalkonium
Chloride. As an alternate first aid treatment, 2.5% calcium
gluconate gel may be continuously massaged into the burn
area. Further treatment by physician.
Inhalation : Remove to fresh air. Keep patient warm and at rest. Get
competent medical attention immediately.
If breathing has stopped, start artificial respiration at once. An
authorized person should administer oxygen to a victim who is
having difficulty breathing, until the victim is able to breathe
Page 2 / 12

Modified Hydrofluoric Acid - 90%
Version 1 Revision Date 01/21/2010 Print Date 01/21/2010
easily by himself. Calcium Gluconate, 2.5% in normal saline
may be given by nebulizer with oxygen. Do not give stimulants
unless instructed to do so by a physician. Victim should be
examined by a physician and held under observation for at least
24 hours.
Skin contact : Remove the victim from the contaminated area and immediately
wash the burned area with plenty of water for a minimum of 15
minutes. Limit washing to 5 minutes if treatment specific for HF
exposure is available. Remove all contaminated clothing while
washing continuously. After thorough washing for at least 5
minutes, the burned area should be immersed in a solution of
0.13% iced aqueous Benzalkonium Chloride until pain is
relieved. As an alternate first aid treatment, 2.5% calcium
gluconate gel may be continuously massaged into the burn area
until the pain is relieved. For larger burns or burns treated with
calcium gluconate gel (in which pain is present longer than 30
minutes), a physician should inject 5% aqueous calcium
gluconate beneath, around and in the burned area. Use of local
anesthetics is not recommended, as reduction in pain is an
indicator of effectiveness of treatment.
Eye contact : Protect unharmed eye. Irrigate eyes for at least 15 minutes with
copious quantities of water, keeping eyelids apart and away
from eyeballs during irrigation. Get competent medical attention
immediately, preferably an eye specialist. If a physician is not
immediately available, apply one or two drops of 0.5% tetracaine
hydrochloride solution, or other aqueous, topical ophthalmic
anesthetic and continue irrigation. Do not use the solution
described for skin treatment (Benzalkonium Chloride). Use no
other medications unless instructed to do so by a physician.
Rubbing of the eyes is to be avoided. Irrigate with 1% calcium
gluconate in normal saline for 1 to 2 hours to prevent or lessen
corneal damage
Ingestion : Call a physician immediately. Drink plenty of water. Do NOT
induce vomiting. Magnesium hydroxide (milk of Magnesia) as
an antacid may be given.
Notes to physician
Treatment : For large skin area burns (totaling greater than 25 square
inches), for ingestion and for significant inhalation exposure,
severe systemic effects may occur. Monitor and correct for
hypocalcemia, cardiac arrhythmias, hypomagnesemia and
hyperkalemia. In some cases hemodialysis may be indicated.
For certain burns, especially of the digits, use of intra-arterial
calcium gluconate may be indicated. For inhalation exposures,
treat as chemical pneumonia. Monitor for hypocalcemia. 2.5%

calcium gluconate in normal saline by nebulizer or by
intermittent positive pressure breathing with 100% oxygen may
decrease pulmonary damage. Bronchodilators may also be
administered.
