It is particularly treacherous in that a warning pain often only occurs several hours after contact. Home, Cabinets for acids and alkalis, Safe handling and storage of HF. The dermal absorption and skin damaging potential of HF was assessed ex vivo. HF concentration is the main factor determining absorption and skin damage., cabinets designed for these specific substances. In addition, the chemical should be stored in such a way that only competent and reliable persons have access. If the fumes are breathed in swelling of the upper airway and bleeding may occur. doi: 10.1016/j.burns.2013.12.003. 691-692.

NIH 63584 Gründau / Germany Hydrofluoric acid is extremely corrosive and can cause very deep and excruciatingly painful burns and tissue loss. Even at low concentrations, it leads to throat irritation and bronchial catarrh. The solution alone is not enough; hydrofluoric acid accidents always require medical treatment.  |  Fax: +49 6051 9220-10 Hydrofluoric acid exposure: a case report and review on the clinical presentation and management. For HF concentrations of ≥30%, skin damage progressed into deeper skin layers. Burkhart KK, Brent J, Kirk MA, Baker DC, Kulig KW. All first aiders and staff must be informed about the health hazards and first aid measures in the case of a hydrofluoric acid accident and be instructed about how to behave when work-related accidents occur. (2)Department of Dermatology, Institute of Dermatology and … Sensitive viewers beware images of HF acid burn damage to hand and legs. Acids and alkalis should be stored in ventilated cabinets designed for these specific substances. Med., 22 (1980), pp. Get the latest research from NIH:  |  Hydrofluoric acid is used both concentrated and in hydrofluoric acid products. Int Wound J. The clinical effectiveness of the intravenous infusion of calcium gluconate for treatment of hydrofluoric acid burn of distal limbs. However, the storage of hydrofluoric acid is a special case. (B) Histopathology of a skin lesion showing poorly defined tissue structures of the full-layer dermis owing to severe liquefactive necrosis (hematoxylin and eosin stain. doi: 10.1503/cmaj.181078. Weiherfeldsiedlung 16-18 Due to its extremely dangerous properties, extreme care should be taken both when handling and storing hydrofluoric acid! The hydrofluoric acid built-in compartment is available for the tall acid-alkaline cabinets in accordance with TRGS 510, Technical Rules for Hazardous Substances. Get the latest public health information from CDC: Thomasen and Nylander-French, 2012 . Hydrofluoric acid can be stored separately in the cabinet interior. The intradermal HF retention capacity associated with progression and prolongation of HF induced skin effects must be considered in the review of skin decontamination procedures. The height of the collection tray is designed so that a 1-litre container can be removed even when upright on the tray and built-in compartment. MEDICAL TREATMENT FOR HYDROFLUORIC ACID EXPOSURE 3 In contrast to the immediate effects of concentrated HF, the effects of contact with more dilute HF acid or its vapors may be delayed, and this is one of the problems with the recognition of some HF burns. Please enable it to take advantage of the complete set of features! >50% hydrofluoric acid usually causes immediate burns that are extremely painful and slow to heal. Technical ventilation is provided via the existing extraction system from the cabinet interior. Therefore, the first aid chain between company, company doctor, hospital or emergency service should be determined in advance. Diluted hydrofluoric acid can be part of various degreasing, washing and cleaning agents for industry and trade. J.M. Despite local and systemic hazards associated with HF, information on percutaneous penetration and tissue damage is rare. Holla R, Gorter RR, Tenhagen M, Vloemans AF, Breederveld RS. Complications can include electrolyte, heart, lung, kidney, and neurological problems. Hydrofluoric acid is corrosive and highly toxic. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved. HF rapidly penetrated through skin under formation of a considerable intradermal reservoir (∼13–67% of total absorbed fluoride). Alterations of skin were histologically evaluated. 5% ... P.B. Since the chemical has a corrosive effect on glass, it is used in glass processing for etching, matting and polishing. In particular, the consequences of contamination of the skin with highly concentrated hydrofluoric acid are very severe and can be fatal. HF is a REALLY bad acid to work with, and as a degreed chemist, if I don’t want to work with it, then that is something to take seriously. J. Occup. 2016 Oct;13(5):1023. doi: 10.1111/iwj.12306.
