	Special

Clear colorless liquids with a strong unpleasant odor. Flash point 79 - 97°F. Less dense than water. Vapors heavier than air. Toxic oxides of nitrogen produced during the combustion of. Used as a solvent and to make other chemicals.

• Highly Flammable

Highly flammable. Soluble in water.

Special Hazards of Combustion Products: Emits toxic fumes under fire conditions. Forms explosive mixture in air. (USCG, 1999)

Harmful if swallowed, inhaled or absorbed through the skin. Causes severe irritation. High concentrations are extremely destructive to tissues of the mucous membranes and upper respiratory tract, eyes and skin. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, vomiting and gastrointestinal disturbances. (USCG, 1999)

PICOLINES neutralizes acids in exothermic reactions to form salts plus water. It is incompatible with isocyanates, halogenated organics, peroxides, phenols, sulfuric acid, epoxides, anhydrides, acid halides and iron (II) sulfate. Gamma picoline may generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides. Dangerous fire hazard when exposed to heat, flame or oxidizers. Severe explosion hazards in the form of vapor, when exposed to flame or spark. Reacts violently with chlorosulfonic acid; CrO3; maleic anhydride; HNO3; oleum; perchromates; B-propiolactone; AgClO4; H2SO4;formamide; SO3; I. Dangerous when heated to decomposition it emits highly toxic fumes of cyanides; can react vigorously with oxidizing materials.

• Amines, Phosphines, and Pyridines

Use caution: Liquids with this reactive group classification have been known to react with the absorbent listed below.

• Mineral-Based & Clay-Based Absorbents

Excerpt from 129 [Flammable Liquids (Water-Miscible / Noxious)]:

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

LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 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)

Excerpt from 129 [Flammable Liquids (Water-Miscible / Noxious)]:

CAUTION: The majority of these products have a very low flash point. Use of water spray when fighting fire may be inefficient.

SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam. Do not use dry chemical extinguishers to control fires involving nitromethane (UN1261) or nitroethane (UN2842).

LARGE FIRE: Water spray, fog or alcohol-resistant foam. Avoid aiming straight or solid streams directly onto the product. If it can be done safely, move undamaged containers away from the area around the fire.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices 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. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020)

Excerpt from 129 [Flammable Liquids (Water-Miscible / Noxious)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. 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. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2020)

Wear self-contained breathing apparatus, rubber boots, heavy rubber gloves, and protective clothing. (USCG, 1999)

No information available.

INHALATION: CALL FOR MEDICAL AID. Remove victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

EYES: Flush with copious amounts of water for at least 15 minutes. Assure adequate flushing of the eyes by separating eyelids with fingers.

SKIN: Flush with copious amounts of water for at least 15 minutes while removing contaminated clothing and shoes. (USCG, 1999)
