Anwendungen & Verwendung

Verwenden

As catalyst in polyamide manufacture.

AMMONIUM HYPOPHOSPHITE liberates spontaneously flammable phosphine at about 240 °C [Mellor 8:880 1946-47]. Some inorganic materials, such as hypophosphites, tend to form explosive mixtures with perchloric acid when hot [Analyst 84:215 1959].
Air and Water ReactionsWater soluble. It liberates spontaneously flammable phosphine at about 240 °C [Mellor 8:880 1946-47].
Other Hazardous ReactionsEvolves flammable and toxic fumes on heating.
Toxic Combustion ProductsSpecial hazards arising from the substance or mixture: Thermal decomposition may produce toxic fumes of phosphorus oxides and/or phosphine, ammonia nitrogen oxides (NOx), oxides of phosphorus.
BrandbekämpfungFire Extinguishing Agents: Carbon dioxide, dry chemical, or water spray (USCG, 1999)
Erste HilfeNot applicable (USCG, 1999)
BrandbekämpfungsverfahrenSuitable extinguishing media: Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.Advice for firefighters: Wear self contained breathing apparatus for fire fighting if necessary.
LagerbedingungenKeep container tightly closed in a dry and well-ventilated place. Hygroscopic.Keep well closed.
ReinigungsverfahrenACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. Environmental precautions: Do not let product enter drains. Methods and materials for containment and cleaning up: Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal.
EntsorgungsverfahrenSRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in air, soil or watereffects on animal, aquatic and plant lifeand conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.Product: Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this materialContaminated packaging: Dispose of as unused product.
Preventive MeasuresACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. Environmental precautions: Do not let product enter drains.Precautions for safe handling: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed.Appropriate engineering controls: Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.
Personal Protective Equipment (PPE)Rubber gloves, safety glasses, and normal protective gear. (USCG, 1999)Eye/face protection: Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).Skin protection: Handle with gloves.Body Protection: Impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.Respiratory protection: For nuisance exposures use type P95 (US) or type P1 (EU EN 143) particle respirator. For higher level protection use type OV/AG/P99 (US) or type ABEK-P2 (EU EN 143) respirator cartridges. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
ToxizitätsübersichtIDENTIFICATION AND USE: Ammonium hypophosphite is a solid, forming crystals or white granules. This is a DEA List 1 chemical substance. It is used as a catalyst in nylon manufacture. Up to 1% of ammonium hypophosphite is added as a stabilizer in ammonium iodide preparations. HUMAN STUDIES: Large doses of ammonium salts may have sufficient absorption to produce diuresis and systemic ammonia poisoning, particularly if given parenterally. ANIMAL STUDIES: There are no data available.
Human Toxicity Excerpts/SIGNS AND SYMPTOMS/ ...With large doses of ... ammonium /salts/, there arises the possibility of sufficient absorption to produce diuresis and systemic ammonia poisoning, particularly if material is administered parenterally. /Ammonium salts/
Environmental BioconcentrationFood Chain Concentration Potential: None(1).
Antidote and Emergency Treatment/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Poisons A and B//SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . Cover skin burns with dry sterile dressings after decontamination ... . /Poisons A and B//SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Consider administering a beta agonist such as albuterol for severe bronchospasm ... . Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start IV administration of D5W TKO /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Treat seizures with diazepam or lorazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Poisons A and B//SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary.
