HF exposure requires immediate specific and specialized medical treatment. Compendium of Chemical Hazards: Hydrogen Fluoride and Hydrofluoric Acid (HF) Page 2 of 17 Incident Management . Hydrofluoric acid (HF) exposure is very toxic and can be fatal if not treated immediately. Exposure usually is unintentional and often is due to inadequate use of protective measures. It should never be considered a substitute for medical evaluation and treatment of HF exposures. The incident in Gumi, which the present study addressed, occurred on … Hydrofluoric acid also may be found in home rust removers. HF Exposure Treatment Guide for Physicians Introduction Hydrogen fluoride is a highly corrosive chemical that can cause severe and deep burns on exposure. Hazard … Despite having an irritating odor, HF may reach dangerous levels without an obvious odor. Immediately flush eyes for at least 15 minutes with cool flowing water. Rinse the affected area with copious amounts of cool water for 5 min to remove surface HF residues. Presentation of HF spill. Vapor burns to the skin are treated the same way as liquid HF burns. We report severe cases of inhalation exposure and skin injury which were successfully treated by administering a 5% calcium gluconate solution with a nebulizer and applying 2.5% calcium gluconate jelly, respectively. Poisonous Ingredient. First Aid Treatment for Hydrofluoric (HF) Acid Exposure. 5. Note: Time is of the essence as exposure to HF is a life-threatening emergency. 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. > Eye Exposure: Because HF penetrates deep into tissue, ... A person who has inhaled HF vapors may require prophylactic oxygen treatment. Upon exposure, treatment must be administered immediately or the threat of death is substantial (Bracken, Cuppage, McLaury, Kirmin, & Klaassen, 1985). Therefore, the current study attempts to develop effective safety measures by suggesting an adequate method of emergency treatment for HF inhalation toxicity. Skin Contact. 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. Calcium gluconate combines with HF to form insoluble calcium fluoride. HF is absorbed quickly; however, damage/symptoms can occur hours to days later. In the Event of a Skin or Eye Exposure to HF. If you suspect you may have been exposed to HF but are not experiencing any immediate symptoms, apply immediate first aid nonetheless. Any person exposed to HF must have immediate first aid, followed by immediate medical treatment from a physician. HF concentration of 50 percent or more causes immediate pain on contact with the skin. Treat vapor burns the same way as liquid HF burns. 6. It is imperative that medical assistance be provided for any exposure to HF and the treatment be initiated promptly. 2. Identify the immediate treatment for a serious HF acid burn. Where Found. This reaction prevents calcium from being extracted from tissues and bones. 2. • exposure to hydrogen fluoride may cause systemic effects including cardiotoxicity, secondary to hypocalcaemia, hypomagnesaemia and metabolic acidosis Environment • avoid release to the environment; inform the Environment Agency where appropriate . 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). MEDICAL TREATMENT: For eye exposure, immediately consult an ophthalmologist. The skin will become erythematous within minutes and blistering and edema will occur within one to two hours. 3. 1052 125(anhydrous) 1790 157(solution) Formula. Dilute HF solutions (<40%) may cause delayed pain as long as 24 hours from the initial contact. The prognosis is ultimately dependent on the timeliness and effectiveness of first aid/decontamination. All exposures or suspected to hydrofluoric acid require immediate first aid response and prompt medical treatment. Conversion. Post-treatment with HF/HNO 3 significantly changed the internal pore structure of the Ti scaffold. Delay in first aid or medical treatment will result in greater damage or possibly death. 7664-39-3 RTECS No. 3. Most HF exposures occur by inhalation of the vapor or dermal contact. If you or someone you are with has an exposure, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States. 8. Hydrofluoric acid. Apply liberal amounts of calcium gluconate gel on the burned area and continuously massage into the skin. Identify three potentially serious HF acid exposure scenarios. 1. When HF is diluted to concentrations of less than 10%, they are no longer considered concentrated, but they still require special treatment on exposure. If exposure occurs at an industrial site, obtain and transport any available treatment literature. Calcium gluconate gel is a topical antidote agent for first aid treatment of HF skin exposure. Treatment of hydrofluoric acid burns includes basic life support and appropriate decontamination, followed by neutralization of the acid by use of calcium gluconate or hydrofluoric-specific agent such as Hexafluorine, if available. Immediate action is critical. Anhydrous hydrogen fluoride, Aqueous hydrogen fluoride, HF-A, Hydrofluoric acid CAS No. HF. While there is a lot of literature and research available about HF exposure to the skin, inhalation exposure has had relatively little research completed. The first treatment that should be performed, as with any chemical exposure, is removing soaked clothing and copious irrigation with water. Treat all HF burns very aggressively with calcium gluconate, with delivery depending on mode of exposure. This procedure, along with SSP-0023B, will accompany the patient to the hospital in order to better assist the treating physician. High frequency nonionizing electromagnetic fields (HF-EMF) that are increasingly present in the environment constitute a genuine environmental stimulus able to evoke specific responses in plants that share many similarities with those observed after a stressful treatment. 1,9 This would ideally be performed immediately upon contact with HF, helping to reduce the risk of acidic burn and deeper penetration, but it will have some benefit even if performed later. Symptoms of exposure to hydrofluoric acid may not be immediately evident, and this can provide false reassurance to victims, causing them to delay medical treatment. Depending on the circumstances of the HF exposure, the goal is to deliver a pharmacologic antidote of calcium to the affected area: 3,26-29 Table 2. Assess and manage acute life-threatening conditions in … Material and methods 2.1. 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. Skin; Respiratory Tract; Eyes (ocular) Ingestion; Dermal Exposure. Effects of HF exposure are unique and must be treated in a specialized medi-cal fashion. 9. 7. First aid and treatment for HF exposure can be quite involved and is beyond the scope of this article. mice on the HF diet, which was diminished with probiotic-treatment. An appropriate first response coupled with HF-specific medical treatment is imperative. And after a massive HF spill, we successfully treated HF inhalation-exposure injury and dermal injury. Patients with type 2 diabetes mellitus (T2DM) at risk for heart failure treated with metformin may have reduced deterioration of left ventricular (LV) filling pressures and myocardial relaxation, according to a study published in the Journal for the American College of Cardiologists: Cardiovascular Imaging.. Penn's HF Exposure Response Kits (see above) contain first aid instructions for HF skin and eye exposures. HF interferes with nerve function, meaning that burns may not initially be painful. Hydrofluoric (HF) acid, one of the strongest inorganic acids, is used mainly for industrial purposes (eg, glass etching, metal cleaning, electronics manufacturing). Closed pores were continuously interconnected with adjacent pores from the external to internal zone of the scaffold, as indicated by blue arrows in Fig. WARNING: Burns with concentrated hydrofluoric acid (HF) are usually very serious, with the potential for significant complications due to flu- oride toxicity. The pore size and porosity continuously increased with the acid treatment time, while the overall contour of the scaffold was maintained. A quick response can substantially reduce injury. 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. HF exposure requires immediate specific and specialized medical treatment. DOT ID & Guide. Remove all exposed clothing and immediately wash all exposed areas with copious amounts of water from the safety shower or eyewash. Routes of exposure include the following. Symptoms of HF exposure are often delayed for several hours. Vapor exposures can cause skin and mucous membrane burns as well as damage to pulmonary tissue. Symptoms of HF exposure include irritation of the eyes, skin, nose, and throat, eye and skin burns, and bone damage. Conclusions: Our findings suggest that exposure to DEP causes persistent and sustained inflammation and bacterial alterations in a ROS-RNS mediated fashion, which is exacerbated by concurrent consumption of an HF diet. Have someone call 911 immediately, to facilitate arrival of medical assistance. HF gel should be applied to all skin exposures as long as this does not delay emergency medical treatment. PURPOSE: This procedure is intended to provide accurate First Aid treatment procedures in the event of a Hydroflouric (HF) Acid exposure. In all instances, as the victim is tending to the exposure, someone should call Public Safety at 911 or 258-3333 to arrange for transport to Health Services or UMCP. From a dermal exposure standpoint, various studies have been preformed on the treatment methodologies for hydrofluoric acid exposure. Exposure should be treated with instantaneous and continuous flushing with cold water. Do NOT use it to treat or manage an actual poison exposure. 2. Skin exposure to 50% HF will probably not be immediately painful but will be excruciating, For pinhole-size exposures, HF gel may be applied at the lab before follow-up in the Medical Department. Background Statins are hypothesized to reduce the risk of cardiotoxicity associated with anthracyclines and trastuzumab. The HF first aid instructions can also be found here: First Aid Treatment Instructions for Hydrofluoric Acid Exposure. Identify an important concept about the onset of pain caused by HF acid burns. Any and all victims should be sent to an emergency facility to receive the proper treatment methods. Flush exposed eyes for at least 15 minutes, but flush exposed skin for only five minutes, followed by treatment with a calcium source. Initial treatment of exposure involves removing contaminated clothing and washing with large amount of water over at least 30 minutes. MW7875000. If there is skin exposure to hydrofluoric acid, do the following:15 1. Identify the proper technique for using topical calcium to treat HF acid burns. Case 1: A 52-year old worker used HF for surface treatment after welding stainless steel, and was hospitalized with rapid onset of severe dyspnea. Complications may occur due to fluoride toxicity.
