SECTION 4: First aid measures
4.1 Description of first-aid measures
General advice
- HF exposures are unique. Serious and potentially life threatening effects can occur immediately or up to 24 hours
after exposure.
- Always decontaminate exposure victims before applying first aid or medical treatment.
- Rescuers should wear PPE during rescue and decontamination of victims.
- First aid providers should wear gloves when touching exposed areas or applying calcium gluconate gel to victims.
- In case of splashes to eyes and face, treat eyes first.
- Always seek medical attention if exposed to HF.
In case of inhalation
- Move to fresh air.
- Get immediate medical advice/attention.
- Administer oxygen by mask at a rate of 12 liters/minute.
- Nebulize 2.5%calcium gluconate solution for 15 to 20 minutes minimum or until the victim reaches medical
attention.
- If calcium gluconate is not available, administer oxygen as above until the victim reaches medical attention.
- If respiratory assistance is needed, use indirect methods such as"microshilds"or"AMBU"bag. Do not give mouth
to mouth resuscitation.
- If exposed to HF vapor, expect to see skin and eye exposure. Follow the decontamination and first aid procedures
for skin and eye exposure.
- Be aware to maintain life support if necessary.
In case of skin contact
- In case of HF exposure to skin, go to the nearest source of water or safety shower. Turn water on.
- While washing, remove all clothing, shoes and jewelry.
- Finally,while closing eyes and facing the water flow, remove goggles or respirator face mask.
- HF-resistant gloves should be worn while touching contaminated skin.
- Wash the exposed areas for 5 minutes maximum if first aid treatments are immediately available. Otherwise
continue to wash until first aid treatments are available.
- Immediately apply calcium gluconate gel 2.5%and massage into the affected area; continue to massage while
repeatedly applying gel until 15 minutes after pain is relieved.
- If fingers/finger nails are touched, even if there is no pain, dip them in a bath of 2.5%calcium gluconate for 15 to 20
minutes.
- Seek medical attention as soon as possible. During transportation to a medical facility or while waiting for a
physician to see victim, it is extremely important to continue messaging calcium gluconate gel.
- Be aware to maintain life support if necessary.
In case of eve contact
- Decontamination: Go to the nearest eye wash or clean source of water, open the water valve. Have a trained
person remove contact lenses if present(contact lenses should be prohibited), put your eye(s) in the water flow and

hold eyelids open while flushing.
- After flushing, irrigate eyes with 1%calcium gluconate solution using a nasal cannula cinched over the bridge of the
nose. Dispense 1000 cc of calcium gluconate solution in a continuous flush for a minimum period of 15 minutes, or
if necessary until medical aid is available.
- During transportation to a medical facility or while waiting for a physician to see the victim, it is extremely important
to continue the calcium gluconate irrigation.
- Always obtain specialized medical evaluation &treatment as soon as possible.
- Be aware to maintain life support if necessary.
In case of ingestion
- If HF has been ingested,the victim should be immediately transported to a medical facility.
- Do NOT induce vomiting.
- If the victim is able to swallow, give oral calcium containing antacids or solution.The recommended antidote is
calcium gluconate. However, if no calcium gluconate is at hand,the oral administration of small and limited amount
of milk or water might be considered if it's consistent with local practice.
- Be aware to maintain life support if necessary.
4.2 Most important symptoms and effects, both acute and delayed
In case of skin contact
Symptoms
- Causes severe burns.
- metabolic imbalances
- Life threatening cardiac arrhythmia
Effects
- HF penetrate very fast any tissue It comes in contact with, and do not remain on its surface.
- Initially, the substances will be locally burning, and afterwards they will penetrate into deeper tissues and might
cause the following significant complications:
- In case of lower concentrations, symptoms can be delayed and might appear even 48h after the exposure.
- It is completely absorbed into the body,where it causes acute and severe toxic systemic effects, mainly attributable
to a rapid development of serum hypocalcaemia and hypomagnesaemia and to enzymes blocking.
In case of eve contact
Symptoms
- Causes severe burns.
- Blindness
Effects

Ecotoxicity assessment
Short-term(acute)aquatic hazard
Hydrofluoric acid Harmful to aquatic life.
Long-term (chronic)aquatic hazard
Hydrofluoric acid No adverse chronic effect observed up to and including the threshold of 1 mg/L.
Remarks No data is available on the product itself., Ecological data therefore refers only to
the effects of the decomposition products., Harmful to aquatic organisms.,
Nevertheless, hazard for the environment is limited due to product properties:, .
low chronic toxicity., Product fate is highly dependent on environmental
conditions: pH,temperature, redox potential, mineral and organic content of the
medium ,...
