ERG 2024 Guide 151, page 1GUIDE 151 Substances - Toxic (Non-Combustible) POTENTIAL HAZARDS HEALTH • Highly toxic, may be fatal if inhaled, ingested or absorbed through skin. • Avoid any skin contact. • Fire may produce irritating, corrosive and/or toxic gases. • Runoff from fire control or dilution water may be corrosive and/or toxic and cause environmental contamination. FIRE OR EXPLOSION • Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. • Containers may explode when heated. • Runoff may pollute waterways. • • • 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. 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 in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. 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 151, page 2Substances - Toxic (Non-Combustible) GUIDE 151 EMERGENCY RESPONSE FIRE Small Fire • Dry chemical, CO2 or water spray. Large Fire • Water spray, fog or regular 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. • • Avoid aiming straight or solid streams directly onto the product. Fire Involving Tanks, Rail Tank Cars or Highway Tanks Fight fire from maximum distance or use unmanned master stream devices 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 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 • Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. • Stop leak if you can do it without risk. • Prevent entry into waterways, sewers, basements or confined areas. • Cover with plastic sheet to prevent spreading. • Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. • DO NOT GET WATER INSIDE CONTAINERS. • For solids, prevent dust cloud and avoid inhalation of dust.
