Exercise extreme caution when handling hydrofluoric acid!

Hydrofluoric acid, also known as hydrofluoric acid, is the aqueous solution of hydrogen fluoride (HF). Hydrofluoric acid is a colorless, pungent-smelling liquid. It has a strong corrosive effect on the skin, mucous membranes and the conjunctiva of the eyes.

Effects of contact with hydrofluoric acid:
Hydrofluoric acid has a corrosive effect and is quickly absorbed by the skin and immediately penetrates into deeper layers of tissue. This can attack deeper layers of tissue and bones without the skin appearing to be visibly injured externally. Skin burns are painful and lead to ulcers that are difficult to heal; at low concentrations, pain often only occurs hours after the first contact.
In addition to the corrosive effect, the toxicity contributes to the danger of hydrofluoric acid. The fluoride ions block calcium and magnesium metabolism and inhibit important
enzymes, which leads to acutely threatening metabolic disorders that can even be fatal with multiple organ failure.
Inhaling hydrofluoric acid vapors can lead to burns in the lungs with the formation of pulmonary edema and can be fatal within a short time even at low concentrations (50-100 ppm).

Proven antidotes:
Deeper penetration can be counteracted by injecting the damaged tissue with calcium gluconate solution.
It is therefore recommended to put together a “hydrofluoric acid” emergency kit and keep it ready in the first aid room: calcium gluconate ampoules (10% solution), calcium gluconate solution (1%), calcium gluconate gel or calcium effervescent tablets, tube-mouth ventilator for artificial ventilation.

Danger

Protective measures and rules of conduct

Keep locked up.
Keep the container tightly closed in a well-ventilated place.
If it comes into contact with eyes, immediately rinse thoroughly with water and consult a doctor.
Wear protective gloves made of butyl rubber and protective clothing when working.
In the event of an accident or if you feel unwell, seek medical attention immediately.
Only hand over to qualified persons who are authorized to receive the product!
Secure containers in suitable containers during transport (including within the company)!
Store and handle only in the manufacturer's original bottles!
Handle only in a fume hood and, if possible, in closed equipment.
Eyewash and emergency showerhead required in the immediate vicinity of the workplace.
Keep calcium gluconate preparations ready directly at the workplace.
Preventive skin protection required!
First aid: Medical treatment is always required after hydrofluoric acid injuries!
General
measures:
If you notice liquid on your clothing or skin when working with hydrofluoric acid, you should act as if the liquid were hydrofluoric acid.
Contact with clothing:
Take off clothing immediately and wash it with plenty of water.
Be sure to use suitable protective gloves and avoid any skin contact. Skin contact:
Immediately rinse affected areas of skin with plenty of water, then repeatedly apply calcium gluconate gel and massage in until the pain subsides. Once the pain is gone, continue to massage with the gel for another 15 minutes and seek medical attention immediately.
Eye contact:
Rinse under running water with the eyelid open for 10 minutes,
then apply a sterile protective bandage and seek medical attention immediately.
Ingestion:
Immediately rinse mouth thoroughly (do not induce vomiting), then have the patient drink 1% calcium gluconate solution and seek medical attention immediately.
Calcium, magnesium supplements or milk (or water if necessary) can also be administered.
Inhalation:
Take the casualty out into the fresh air and immediately notify a doctor.
If breathing stops, only use artificial respiration if possible (observe self-protection!). In case of more severe effects (strong coughing, skin burns larger than the size of the palm of your hand, swallowing soluble fluorides or solutions containing hydrofluoric acid), an emergency doctor must be called: Emergency number: 144 Toxicological Information Center: 145 Classification of H-phrases Acute Tox. 2 H330 Fatal if inhaled Acute Tox. 1 H310 Fatal if in contact with skin Acute Tox. 2 H300 Le
