PURPOSE: This procedure is intended to provide accurate First Aid treatment procedures in the event of a Hydroflouric (HF) Acid exposure. 5. Poisonous Ingredient. Remove all exposed clothing and immediately wash all exposed areas with copious amounts of water from the safety shower or eyewash. WARNING: Burns with concentrated hydrofluoric acid (HF) are usually very serious, with the potential for significant complications due to flu- oride toxicity. Initial treatment of exposure involves removing contaminated clothing and washing with large amount of water over at least 30 minutes. 8. From a dermal exposure standpoint, various studies have been preformed on the treatment methodologies for hydrofluoric acid exposure. While there is a lot of literature and research available about HF exposure to the skin, inhalation exposure has had relatively little research completed. > Eye Exposure: Because HF penetrates deep into tissue, ... A person who has inhaled HF vapors may require prophylactic oxygen treatment. Any and all victims should be sent to an emergency facility to receive the proper treatment methods. Assess and manage acute life-threatening conditions in … The prognosis is ultimately dependent on the timeliness and effectiveness of first aid/decontamination. If you suspect you may have been exposed to HF but are not experiencing any immediate symptoms, apply immediate first aid nonetheless. 3. For minor exposures with very dilute hydrofluoric acid (HF): mix 10 mL of 10% calcium gluconate with 100 mL of normal saline to give an approximately 1% calcium gluconate solution. Do NOT use it to treat or manage an actual poison exposure. Calcium gluconate combines with HF to form insoluble calcium fluoride. First Aid Treatment for Hydrofluoric (HF) Acid Exposure. When HF is diluted to concentrations of less than 10%, they are no longer considered concentrated, but they still require special treatment on exposure. Treatment of Hydrofluoric Acid (HF) Exposure Quick Reference NOTE: In addition to the usual medical history, the physician should obtain the following information: concentration of HF, date and time of exposure, duration of exposure, how exposure occurred, body parts exposed/affected, first aid measures instituted (what, when, how long). Hydrofluoric acid (HF) exposure is very toxic and can be fatal if not treated immediately. Hazard … Hydrofluoric acid. This procedure, along with SSP-0023B, will accompany the patient to the hospital in order to better assist the treating physician. It is imperative that medical assistance be provided for any exposure to HF and the treatment be initiated promptly. Presentation of HF spill. Apply liberal amounts of calcium gluconate gel on the burned area and continuously massage into the skin. The treatment plan for those who have been exposed to HF chemical will vary depending on the level of exposure and the concentration of the chemical present within the environment. MEDICAL TREATMENT: For eye exposure, immediately consult an ophthalmologist. Dilute HF solutions (<40%) may cause delayed pain as long as 24 hours from the initial contact. Material and methods 2.1. Inhalation of HF can cause serious damage and treatment should be done in a medical setting because there is little to no effective treatment outside of a clinical setting. If exposure occurs at an industrial site, obtain and transport any available treatment literature. mice on the HF diet, which was diminished with probiotic-treatment. 2. It should never be considered a substitute for medical evaluation and treatment of HF exposures. Rinse the affected area with copious amounts of cool water for 5 min to remove surface HF residues. Treat all HF burns very aggressively with calcium gluconate, with delivery depending on mode of exposure. Symptoms of HF exposure are often delayed for several hours. 7. Hydrofluoric acid also may be found in home rust removers. Despite having an irritating odor, HF may reach dangerous levels without an obvious odor. 1052 125(anhydrous) 1790 157(solution) Formula. Exposure should be treated with instantaneous and continuous flushing with cold water. Identify an important concept about the onset of pain caused by HF acid burns. Therefore, the current study attempts to develop effective safety measures by suggesting an adequate method of emergency treatment for HF inhalation toxicity. DOT ID & Guide. Routes of exposure include the following. Penn's HF Exposure Response Kits (see above) contain first aid instructions for HF skin and eye exposures. Vapor exposures can cause skin and mucous membrane burns as well as damage to pulmonary tissue. Eye Exposure: Because HF penetrates deep into tissue, exposure of hydrofluoric acid solution or vapor to the eye can produce more extensive damage than other acids in similar concentrations. Skin Contact. Identify three potentially serious HF acid exposure scenarios. HF gel should be applied to all skin exposures as long as this does not delay emergency medical treatment. 9. Calcium gluconate gel is a topical antidote agent for first aid treatment of HF skin exposure. Vapor burns to the skin are treated the same way as liquid HF burns. Flush exposed eyes for at least 15 minutes, but flush exposed skin for only five minutes, followed by treatment with a calcium source. The pore size and porosity continuously increased with the acid treatment time, while the overall contour of the scaffold was maintained. For pinhole-size exposures, HF gel may be applied at the lab before follow-up in the Medical Department. 2. MW7875000. Identify the immediate treatment for a serious HF acid burn. Post-treatment with HF/HNO 3 significantly changed the internal pore structure of the Ti scaffold. HF is absorbed quickly; however, damage/symptoms can occur hours to days later. Upon exposure, treatment must be administered immediately or the threat of death is substantial (Bracken, Cuppage, McLaury, Kirmin, & Klaassen, 1985).
