| Hazard Information | Back Directory | [Potential Exposure]
This material is used as a pesticide
and miticide, wood preservative, soldering flux; light metal
casting; and in the etching of glass. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running
water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation
is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed. As
first aid for pulmonary edema, a doctor or authorized paramedic
may consider administering a drug or other inhalation
therapy. | [Shipping]
UN2856 Fluorosilicates, n.o.s., Hazard Class:
6.1; Labels: 6.1-Poisonous materials, Technical Name
Required. | [Incompatibilities]
Aqueous solution is highly corrosive.
Contact with acids reacts to form hydrogen fluoride,
which is a highly corrosive and forms a toxic gas.
Corrosive to aluminum. Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, epoxides. Ammonium fluorosilicate
reacts with water to form
hydrofluoric acid, a source of fluoride ions. Unlike other
halide ions, the fluoride ion is highly reactive, acting as a
weak base and participating in some unique reactions. In
particular, fluorides react strongly with compounds containing
calcium, magnesium, or silicon ions, which means
that solutions containing soluble fluorides are corrosive to
both living tissue and glass. Hydrofluoric acid can cause
severe chemical burns and is one of the few materials that
can etch glass. It is also a toxic gas in its anhydrous
form. | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Incineration. |
