Guide 132: Flammable Liquids - Corrosive

ERG 2024 Guide 132, page 1GUIDE 132 Flammable Liquids - Corrosive POTENTIAL HAZARDS FIRE OR EXPLOSION • Flammable/combustible material. • May be ignited by heat, sparks or flames. • Vapors may form explosive mixtures with air. • Vapors may travel to source of ignition and flash back. • Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.). • Vapor explosion hazard indoors, outdoors or in sewers. • Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. • Runoff to sewer may create fire or explosion hazard. • Containers may explode when heated. • Many liquids will float on water. • • • • • HEALTH May cause toxic effects if inhaled or ingested. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or asphyxiation, especially when in closed or confined areas. Runoff from fire control or dilution water may cause environmental contamination. PUBLIC SAFETY CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover. Keep unauthorized personnel away. Stay upwind, uphill and/or upstream. Ventilate closed spaces before entering, but only if properly trained and equipped. • • • • PROTECTIVE CLOTHING • Wear positive pressure self-contained breathing apparatus (SCBA). • Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE. • Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. EVACUATION Immediate precautionary measure • Isolate spill or leak area for at least 50 meters (150 feet) in all directions. Spill • For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances. • For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary. Fire • If tank, rail tank car or highway tank 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 2024 Guide 132, page 2Flammable Liquids - Corrosive GUIDE 132 EMERGENCY RESPONSE FIRE • Some of these materials may react violently with water. Small Fire • Dry chemical, CO2, water spray or alcohol-resistant foam. Large Fire • Water spray, fog or alcohol-resistant foam. • If it can be done safely, move undamaged containers away from the area around the fire. • Dike runoff from fire control for later disposal. • Do not get water inside containers. Fire Involving Tanks, Rail Tank Cars or Highway Tanks • 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 in direct contact with flames. • For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. SPILL OR LEAK • 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 with earth, sand or other non-combustible material. • For hydrazine, absorb with DRY sand or inert absorbent (vermiculite or absorbent pads). • • 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. FIRST AID Refer to the “General First Aid” section. Specific First Aid: • For corrosives, in case of contact, immediately flush skin or eyes with running water for at least 30 minutes. Additional flushing may be required. • In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing if adhering to skin. In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. Please consult the shipping paper and/or the "ERAP" section. ERG 2024 Page 195#
