General Description
Powdered or finely divided metal suspended in a flammable organic solvent. Dry powder left after the evaporation of the solvent is easily ignited. Static electricity may be sufficient to ignite the powder.
Hazards
Reactivity Alerts
- Strong Reducing Agent
- Water-Reactive
- Pyrophoric
Air & Water Reactions
Highly flammable. May ignite on contact with air or moist air. Small amounts of water may greatly accelerate combustion. May burn rapidly with flare-burning effect. The severity of the fire depends on the size of the zirconium particles. Finely divided zirconium reacts with the most vigor. The initiation of a explosion has occurred by spark and by electrostatic ignition.
Fire Hazard
Excerpt from 170
[Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:
May react violently or explosively on contact with water. Some are transported in flammable liquids. May be ignited by friction, heat, sparks or flames. Some of these materials will burn with intense heat. Dusts or fumes may form explosive mixtures in air. Containers may explode when heated. May re-ignite after fire is extinguished. (ERG, 2020)
Health Hazard
Excerpt from 170
[Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:
Oxides from metallic fires are a severe health hazard. Inhalation or contact with substance or decomposition products may cause severe injury or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2020)
Reactivity Profile
ZIRCONIUM is a reducing agent. Likely to react with oxidizing agents such as chromates, dichromates, sulfates, molybdates, and tungstates of lithium, sodium, potassium, rubdium, and cesium [Ellern 1968. p.249]. A mixture of hydrated borax and zirconium explodes when heated [Mellor 7:116 1946-47]. An explosion occurred when zirconium sponge was placed in a beaker of carbon tetrachloride [Allison 1969]. Zirconium explodes violently with cupric oxide or lead oxide [Mellor 7:116 1946-47]. A mixture of powdered zirconium and potassium nitrate explodes when heated above the melting point [Mellor 7:116 1946-47].

Response Recommendations
Isolation and Evacuation
Excerpt from 170
[Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:
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.
LARGE SPILL: Consider initial downwind evacuation for at least 50 meters (160 feet).
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)
Firefighting
Excerpt from 170
[Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:
DO NOT USE WATER, FOAM OR CO2. Dousing metallic fires with water will generate hydrogen gas, an extremely dangerous explosion hazard, particularly if fire is in a confined environment (i.e., building, cargo hold, etc.). Use DRY sand, graphite powder, dry sodium chloride-based extinguishers, or class D extinguishers. Confining and smothering metal fires is preferable rather than applying water. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: If impossible to extinguish, protect surroundings and allow fire to burn itself out. (ERG, 2020)
Non-Fire Response
Excerpt from 170
[Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2020)
Protective Clothing
Excerpt from ERG Guide 170 [Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:
Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

First Aid
Excerpt from 170
[Metals (Powders, Dusts, Shavings, Borings, Turnings, or Cuttings, etc.)]:
Call 911 or emergency medical service. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air if it can be done safely. Give artificial respiration if victim is not breathing. 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. Keep victim calm and warm.
