What is this information?
)
CAS Number - Chemical Abstracts Service registry number. Unique identification number assigned to this chemical by the American Chemical Society.
UN/NA Number - The United Nations-North America number (also called UN number or DOT number). 4-digit number identifying an individual chemical or group of chemicals with similar characteristics. Required on shipping papers; often shown on placards or labels. This numbering system was developed by the U.S. Department of Transportation, and then became the UN standard system for classifying hazardous materials.

CHRIS Code - 3-letter code used by the U.S. Coast Guard to identify individual chemicals included in its CHRIS (Chemical Hazards Response Information System) manual.
NFPA 704 - Text description of the diamond-shaped placard, which contains codes indicating the level of the chemical's health, flammability, and instability hazards, along with special hazards such as water- and air-reactivity. See a guide to the NFPA diamond.
General Description - Brief description of the chemical's general appearance, behavior, and hazardousness.

)
Reactivity Alerts - Special alerts if the chemical is especially reactive
(see list of reactivity alerts).
Air & Water Reactions - Special alerts if the chemical reacts with air, water, or moisture.
Fire Hazard - Description of the chemical's fire hazards (such as flammability, explosion risk, or byproducts that may evolve if the chemical is burned).
Health Hazard - Description of the chemical's health hazards (such as toxicity, flammability, or corrosivity).
Reactivity Profile - Description of the chemical's potential reactivity with other chemicals, air, and water. Also includes any other intrinsic reactive hazards (such as polymerizable or peroxidizable).
Reactive Groups - List of reactive groups that the chemical is assigned to, based on its known chemistry. Reactive groups are categories of chemicals that react in similar ways because their chemical structures are similar. Reactive groups are used to predict reactivity when you add a chemical to MyChemicals. Read more about reactive groups.

Reactivity Alerts
- Highly Flammable
Air & Water Reactions
Highly flammable. Insoluble in water.
Fire Hazard
Special Hazards of Combustion Products: Combustion yields beryllium oxide fume, which is toxic if inhaled.
Behavior in Fire: Powder may form explosive mixture with air. (USCG, 1999)
Behavior in Fire: Powder may form explosive mixture with air. (USCG, 1999)
Health Hazard
Any dramatic, unexplained weight loss should be considered as possible first indication of beryllium disease. Dust is extremely toxic when inhaled; symptoms include coughing, shortness of breath, and acute or chronic lung disease. There is no record of illness from ingestion of beryllium. Contact with dust causes conjunctival inflammation of eyes and dermatitis. (USCG, 1999)
Reactivity Profile
Boron trifluoride reacts with incandescence when heated with alkali metals or alkaline earth metals except magnesium [Merck 11th ed. 1989]. Finely divided or amalgamated metal reacts with HCl, dil HNO3, or dil H2SO4; attacked by strong base with evolution of hydrogen gas [Merck 11th ed. 1989]. It has been determined experimentally that a mixture of beryllium powder with carbon tetrachloride or with trichloroethylene will flash or spark on heavy impact [ASESB Pot. Incid. 39 1968]. The reaction between beryllium and the vapors of phosphorus proceeds with incandescence [Mellor 8:842 1946-47].

Isolation and Evacuation
Excerpt from GUIDE 134 [Flammable Solids - Toxic and/or Corrosive]:
As an immediate precautionary measure, isolate spill or leak area for at least 25 meters (75 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 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, 2012)
As an immediate precautionary measure, isolate spill or leak area for at least 25 meters (75 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 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, 2012)
Firefighting
Excerpt from GUIDE 134 [Flammable Solids - Toxic and/or Corrosive]:
SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam.
LARGE FIRE: Water spray, fog or alcohol-resistant foam. Move containers from fire area if you can do it without risk. Use water spray or fog; do not use straight streams. Do not get water inside containers. Dike fire-control water for later disposal; do not scatter the material.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. 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, 2012)

Non-Fire Response
Excerpt from GUIDE 134 [Flammable Solids - Toxic and/or Corrosive]:
Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop leak if you can do it without risk. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Prevent entry into waterways, sewers, basements or confined areas. Use clean non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. (ERG, 2012)

Protective Clothing
Skin: Wear appropriate personal protective clothing to prevent skin contact.
Eyes: Wear appropriate eye protection to prevent eye contact.
Wash skin: The worker should wash daily at the end of each work shift.
Remove: Work clothing that becomes wet or significantly contaminated should be removed and replaced.
Change: Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premise.
Provide: Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection. (NIOSH, 2003)
