(Combustible/Water-Sensitive)

POTENTIAL HAZARDS

FIRE OR EXPLOSION

* 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.

HEALTH

* 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.

PUBLIC SAFETY

* 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.

PROTECTIVE CLOTHING

* 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.

EVACUATION

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.

EMERGENCY RESPONSE

FIRE

* 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.

SPILL OR LEAK

* 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.

FIRST AID

* 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.
