• Combustible material: may burn but does not ignite readily.
• Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff.
• When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
• Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks).
• Vapors may travel to source of ignition and flash back.
• Contact with metals may evolve flammable hydrogen gas.
• Containers may explode when heated or if contaminated with water.

• TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns, or death.
• Reaction with water or moist air will release toxic, corrosive or flammable gases.
• Reaction with water may generate much heat which will increase the concentration of fumes in the air.
• Fire will produce irritating, corrosive and/or toxic gases.
• Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

• CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
• Isolate spill or leak area immediately for at least 50 to 100 meters (160 to 330 feet) in all directions.
• Keep unauthorized personnel away.
• Stay upwind.
• Keep out of low areas.
• Ventilate enclosed areas.

• Wear positive pressure self-contained breathing apparatus (SCBA).
• Wear chemical protective clothing which is specifically recommended by the manufacturer. It may provide little or no thermal protection.
• Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations.

Spill

• See the Table of Initial Isolation and Protective Action Distances for highlighted substances. For non-highlighted substances, increase, in the downwind direction, as necessary, the isolation distance shown under "PUBLIC SAFETY".

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.

• Note: Most foams will react with the material and release corrosive/toxic gases.

Small Fires

• CO2, dry chemical, dry sand, alcohol-resistant foam.

Large Fires

• Water spray, fog or alcohol-resistant foam.
• FOR CHLOROSILANES, DO NOT USE WATER; use AFFF alcohol-resistant medium expansion foam.
• Move containers from fire area if you can do it without risk.
• Use water spray or fog; do not use straight streams.

Fire involving Tanks or Car/Trailer Loads

• Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
• Do not get water inside containers.
• 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.

• ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
• All equipment used when handling the product must be grounded.
• Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
• Stop leak if you can do it without risk.
• A vapor suppressing foam may be used to reduce vapors.
• FOR CHLOROSILANES, use AFFF alcohol-resistant medium expansion foam to reduce vapors.
• DO NOT GET WATER on spilled substance or inside containers.
• Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material.
• Prevent entry into waterways, sewers, basements or confined areas.

Small Spills

• Cover with DRY earth, DRY sand, or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain.
• Use clean non-sparking tools to collect material and place it into loosley covered plastic containers for later disposal.

• Move victim to fresh air.
• Call 911 or emergency medical service.
• Apply artificial respiration if victim is not breathing.
• Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce 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.
