Since I strongly disagree and don’t have the time to argue. I would not use hydrofluoric acid. But if you’re looking for and opinion on this board you will get someone that prefers the worse of these two evils.
Open and encyclopedia they have tested chemicals on specific things and it will give you some accurate information.

Fire Extinguishing Media: Keep upwind of fire. Use water or carbon dioxide
on fires in which Hydrofluoric Acid is involved.
In case of fire, the sealed containers can be
kept cool by spraying with water.
Special Information: In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained
breathing apparatus with full facepiece operated
in the pressure demand or other positive pressure
mode. Avoid getting water in tanks or drums;
water can cause generation of heat and
spattering. In contact with air, the acid gives
off corrosive fumes which are heavier than air.
Reactivity Data SECTION 3
--------------- ---------
Stability: Stable at room temperature (68 F) when stored and
used under proper conditions.
Hazardous Decomposition
Products: On contact with metals, liberates hydrogen gas.
On heating to decomposition, could yield toxic
fumes of fluorides. Attacks glass and other
silicon containing compounds. Reacts with silica
to reduce silicon tetrafluoride, a hazardous
colorless gas.
Hazardous Polymerization: Will not occur.
Incompatibilities: Arsenic trioxide, phosphorus pentoxide, ammonia,
calcium oxide, sodium hydroxide, sulfuric acid,
vinyl acetate, ethylenediamine, acetic anhydride.
Will also react with steam or water to produce
toxic fumes.
Leak/Spill Disposal Information SECTION 4
------------------------------- ---------
Notify safety personnel, provide adequate ventilation, and remove ignition
sources since hydrogen may be generated by reactions with metals. Use
protective clothing and equipment. Do not flush to sewers or waterways. Spills:
Evacuate the danger area. Apply magnesium sulfate (dry) to the spill area.
Follow up with inert absorbent (acid spill tamer ) and add soda ash or
magnesium oxide and slaked lime. Containerize in plastic materials and save for
disposal. Wash spill site with soda ash solution. Disposal: The neutralized
slurry can be scraped up for disposal in a RCRA approved waste facility. NOTE:
Porous materials (concrete, wood, plastic, etc.) will absorb HF and become a
hazard for an indefinite time. Such spills should be cleaned and neutralized
immediately. Reportable Quantity (RQ)(CWA/CERCLA): 100 lbs. ca. 200 lbs.
product.
Ensure compliance with local, state and federal regulations.
Health Hazard Information SECTION 5
------------------------- ---------
A. Exposure/Health Effects
---------------------------
Inhalation: Severely corrosive to the respiratory tract. May
cause sore throat, coughing, labored breathing and
lung congestion/inflammation.
Ingestion: Corrosive. May cause sore throat, abdominal pain,
diarrhea, vomiting, and severe burns of the
digestive tract.
Skin Contact: Corrosive to the skin. Skin contact causes serious
skin burns which may not be immediately apparent or
painful. Symptoms may be delayed 8 hours or longer.
The fluoride ion readily penetrates the skin
causing destruction of deep tissue layers and even
bone.
Eye Contact: Corrosive to the eyes. Symptoms of redness, pain,
blurred vision, and permanent eye damage may occur.
Chronic Exposure: Intake of more than 6 mg of fluorine per day may
result in fluorosis. Hypocalcemia and
hypomagnesemia can occur from absorption of
fluoride ion into blood stream.
Aggravation of
Pre-existing Conditions: Persons with pre-existing skin disorders, eye
problems, or impaired kidney or respiratory
function may be more susceptible to the effects
of this substance.
B. FIRST AID
-------------
For any route of contact: Detailed First Aid procedure should be planned before
beginning work with HF.
Inhalation: Get medical help immediately. If patient is
unconscious, give artificial respiration or use
inhalator. Keep patient warm and resting, and send to
hospital after first aid is complete.
Ingestion: DO NOT INDUCE VOMITING because of probable severe
burns. If patient is conscious, give large quantities
of milk or, if not available, water. Send to hospital
immediately.
Skin Exposure: Get medical help immediately. Remove contaminated
clothing and immediately wash skin with plenty of water
to remove acid. Without delay, cover the burn with a
generous amount of 50:50 water/magnesium sulfate paste
or a 2-1/2% calcium gluconate paste. (Mix calcium
gluconate U.S.P. powder with Unibase, a Parke-Davis
water soluble ointment.) Keep this poultice in place
until medical help arrives or patient has been
transferred to hospital emergency room.
Eye Exposure: Get medical help immediately. Wash open eyes thoroughly
with large but gentle stream of water for 15 minutes.
Do not use oily drops or ointment. Place ice pack on
eyes until reaching emergency room.
C. TOXICITY (RTECS, 1986)
------------
Inhalation rat LC50: 1276 ppm/1H. Mutation references cited. Reproductive
References cited.
Occupational Control Measures SECTION 6
----------------------------- ---------
Airborne Exposure Limits: -OSHA Permissible Exposure Limit (PEL): 3 ppm
(TWA), 6 ppm (STEL) as F ACGIH Threshold Limit
Value (TLV): 3 ppm Ceiling as F
Ventilation System: A system of local and/or general exhaust is
recommended to keep employee exposures below the
Airborne Exposure Limits. Local exhaust
ventilation is generally preferred because it can
control the emissions of the contaminant at its
source, preventing dispersion of it into the
general work area. Please refer to the ACGIH
document, "Industrial Ventilation, A Manual of
Recommended Practices", most recent edition, for
details.
Personal Respirators If the PEL is exceeded, wear a supplied air, full
(NIOSH Approved) face-piece respirator, airlined hood, or
self-contained breathing apparatus.
Skin Protection: Wear protective clothing, including boots or
safety shoes with polyvinyl chloride (PVC) or
neoprene. Use chemical goggles and/or a full face
shield. Wear coveralls with long sleeves,
gauntlets and gloves of PVC or neoprene. A high
degree of protection is obtained with an
air-inflated suit with mask and safety belt. Use
protection suitable for conditions.
Eye Protection: Use chemical safety goggles and/or full face
shield where splashing is possible. Contact
lenses should not be worn when working with this
material. Maintain eye wash fountain and quick
drench facilities in work area.
Storage and Special Information SECTION 7
------------------------------- ---------
Keep in tightly closed polyethylene containers. Store in a cool, dry place with
adequate ventilation separated from other chemicals. Protect from physical
damage. Storage facilities should be constructed for containment and
neutralization of spills. Handling and storage of HF requires special materials
and technology for containers, pipes, valves, etc., which is available from
suppliers.
