Diphoterine
Diphoterine® is a Human decontamination, decontamination solution used in first aid for the emergency treatment of Chemical hazard, chemical spills to the eyes and body. Mechanism of action Diphoterine® solution contains an Amphoterism, amphoteric, Chelation, chelating molecule: a substance which is capable of reacting with both acids and alkalis when applied to either type of chemical spill, stopping the aggressive action of a corrosive or irritant chemical, halting the reaction with the body. However, it is not fully effective at halting Hydrofluoric acid burn, the body's reaction with hydrofluoric acid. This is because hydrofluoric acid is poisonous as well as corrosive. Treatment with either Hexafluorine or calcium gluconate is required to deal with hydrofluoric acid contamination. Like all of the emergency treatments, Diphoterine® solution is not a substitute for professional medical attention, so immediate attention from emergency medical personnel should always be sough ...

Human Decontamination
Human decontamination is the process of removing hazardous materials from the human body, including chemicals, radioactive substances, and infectious material. General principle People suspected of being contaminated are usually separated by sex, and led into a decontamination tent, trailer, or pod, where they shed their potentially contaminated clothes in a strip-down room. They then enter a wash-down room where they are showered. Finally, they enter a drying and re-robing room to be issued clean clothing, a jumpsuit, or other attire. Some more structured facilities include six rooms (strip-down, wash-down and examination rooms, for each of men's and women's side as per attached drawing). Some facilities, such as Modecs, and many others, are remotely operable, and function like "human car washes". Common lathering in soap, removes external dust that may contain radioisotopes. It is advised that when lathering, effort should be made not to spread potential dust that deposited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Aid
First aid is the first and immediate assistance given to any person with either a minor or serious illness or injury, with care provided to preserve life, prevent the condition from worsening, or to promote recovery. It includes initial intervention in a serious condition prior to professional medical help being available, such as performing cardiopulmonary resuscitation (CPR) while waiting for an ambulance, as well as the complete treatment of minor conditions, such as applying a plaster to a cut. First aid is generally performed by someone with basic medical training. Mental health first aid is an extension of the concept of first aid to cover mental health, while psychological first aid is used as early treatment of people who are at risk for developing PTSD. Conflict First Aid, focused on preservation and recovery of an individual's social or relationship well-being, is being piloted in Canada. There are many situations that may require first aid, and many countries hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Hazard
A chemical hazard is a (non-biological) substance that has the potential to cause harm to life or health. Chemicals are widely used in the home and in many other places. Exposure to chemicals can cause acute or long-term detrimental health effects. There are many types of hazardous chemicals, including neurotoxins, immune agents, dermatologic agents, carcinogens, reproductive toxins, systemic toxins, asthmagens, pneumoconiotic agents, and sensitizers. In the workplace, exposure to chemical hazards is a type of occupational hazard. The use of protective personal equipment (PPE) may substantially reduce the risk of damage from contact with hazardous materials. Long-term exposure to chemical hazards such as silica dust, engine exhausts, tobacco smoke, and lead (among others) have been shown to increase risk of heart disease, stroke, and high blood pressure. Types of chemical hazard Routes of exposure The most common exposure route to chemicals in the work environment is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphoterism
In chemistry, an amphoteric compound () is a molecule or ion that can react both as an acid and as a base. What exactly this can mean depends on which definitions of acids and bases are being used. One type of amphoteric species are amphiprotic molecules, which can either donate or accept a proton (). This is what "amphoteric" means in Brønsted–Lowry acid–base theory. Examples include amino acids and proteins, which have amine () and carboxylic acid () groups, and self-ionizable compounds such as water. Ampholytes are amphoteric molecules that contain both acidic and basic functional groups. For example, an amino acid has both a basic group and an acidic group , and exists as several structures in chemical equilibrium: :H2N-RCH-CO2H + H2O H2N-RCH-COO- + H3O+ H3N+-RCH-COOH + OH- H3N+-RCH-COO- + H2O In approximately neutral aqueous solution (pH ≅ 7), the basic amino group is mostly protonated and the carboxylic acid is mostly deprotonated, so that the predominant spec ...

Chelation
Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a Denticity, polydentate (multiple bonded) ligand and a single central metal atom. These ligands are called chelants, chelators, chelating agents, or sequestering agents. They are usually organic compounds, but this is not a necessity, as in the case of zinc and its use as a maintenance therapy to prevent the absorption of copper in people with Wilson's disease. Chelation is useful in applications such as providing nutritional supplements, in chelation therapy to remove toxic metals from the body, as contrast medium, contrast agents in MRI, MRI scanning, in manufacturing using homogeneous catalysts, in chemical water treatment to assist in the removal of metals, and in fertilizers. Chelate effect The chelate effect is the greater affinity of chelating ligands for a metal ion than that of similar nonchelating (monodentate ...

Acids
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Informa ...

Alkalis
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lime''), ...

Hydrofluoric Acid Burn
A hydrofluoric acid burn is a chemical burn from hydrofluoric acid. Where it contacts the skin it results in significant pain, swelling, redness, and skin breakdown. If the fumes are breathed in swelling of the upper airway and bleeding may occur. Complications can include electrolyte, heart, lung, kidney, and neurological problems. Most exposures occur at work. With concentrations less than 7%, onset of symptoms may not occur for hours while with concentrations greater than 15% onset of symptoms is nearly immediate. Diagnosis should include blood tests for calcium, potassium, and magnesium along with an electrocardiogram. Initial treatment of exposure involves removing contaminated clothing and washing with large amounts of water over at least 30 minutes. Other measures include applying calcium gluconate cream. It is estimated that about a thousand cases occur each year. Most people affected are adult males. Signs and symptoms Symptoms of HF exposure include irritation of th ...

Hydrofluoric Acid
Hydrofluoric acid is a Solution (chemistry), solution of hydrogen fluoride (HF) in water. Solutions of HF are colourless, acidic and highly Corrosive substance, corrosive. It is used to make most fluorine-containing compounds; examples include the commonly used pharmaceutical antidepressant medication fluoxetine (Prozac) and the material polytetrafluoroethylene, PTFE (Teflon). Elemental fluorine is produced from it. It is commonly used to Etching (microfabrication), etch glass and silicon wafers. Uses Production of organofluorine compounds The principal use of hydrofluoric acid is in organofluorine chemistry. Many organofluorine compounds are prepared using HF as the fluorine source, including Polytetrafluoroethylene, Teflon, fluoropolymers, fluorocarbons, and refrigeration, refrigerants such as freon. Many pharmaceuticals contain fluorine. Production of inorganic fluorides Most high-volume inorganic fluoride compounds are prepared from hydrofluoric acid. Foremost are Na3AlF6 ...
