ZINC FLUORIDE

A white powder or crystalline mass. Density 4.84 g / cm3. Slightly soluble in water and denser than water. Also insoluble as a hydrate. ZnF2.xH2O. Used for galvanizing steel and making ceramics.

none

Slightly soluble in water.

Excerpt from 171 [Substances (Low to Moderate Hazard)]:

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot. For UN3508, Capacitor, asymmetric, be aware of possible short circuiting as this product is transported in a charged state. Polymeric beads, expandable (UN2211) may evolve flammable vapours. (ERG, 2020)

INHALATION: Irritation of nasal passages, dryness, and nose bleed. EYES: Irritation may occur. SKIN: Excessive exposure may cause a rash. INGESTION: Salty or soapy taste, salivation, nausea, burning or crampy abdominal pain, vomiting, diarrhea, dehydration, and thirst. (USCG, 1999)

ZINC FLUORIDE can react violently with potassium [Hawley]. Fluorinates organic compounds. Soluble in hot acids.

Solutions of zinc fluoride may contain some hydrofluoric acid, which can cause severe chemical burns and is one of the few materials that can etch glass. Unlike other halide ions, fluoride is quite 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.

Excerpt from 171 [Substances (Low to Moderate Hazard)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)

Excerpt from 171 [Substances (Low to Moderate Hazard)]:

SMALL FIRE: Dry chemical, CO2, water spray or regular foam.

LARGE FIRE: Water spray, fog or regular foam. Do not scatter spilled material with high-pressure water streams. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal.

FIRE INVOLVING TANKS: Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2020)

Excerpt from 171 [Substances (Low to Moderate Hazard)]:

Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent dust cloud. For Asbestos, avoid inhalation of dust. Cover spill with plastic sheet or tarp to minimize spreading. Do not clean up or dispose of, except under supervision of a specialist.

SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.

SMALL SPILL: Pick up with sand or other non-combustible absorbent material and place into containers for later disposal.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Cover powder spill with plastic sheet or tarp to minimize spreading. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2020)

Approved dust and fume respirator, skin and eye protection. (USCG, 1999)

Call a physician.

INHALATION: Remove from exposure.

EYES: Flush with water.

SKIN: Wash with soap and cold water.

INGESTION: Gastric lavage with lime water or a 1% solution of calcium chloride. Give several ounces of lime water at frequent intervals. Milk may be substituted. Aluminum hydroxide gel may be used to bind fluoride. (USCG, 1999)
