| Brandgefahren | Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]:May explode from heat, shock, friction or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames. May burn rapidly with flare-burning effect. Containers may explode when heated. Runoff may create fire or explosion hazard. (ERG, 2024) |

| Gesundheitsgefahren | Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]:Fire may produce irritating, corrosive and/or toxic gases. Ingestion or contact (skin, eyes) with substance may cause severe injury or burns. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2024) |

| Reactivity Profile | Peroxides, such as N-BUTYL-4,4-DI-(TERT-BUTYLPEROXY)VALERATE, are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness. May explode from heat or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames.Peroxides, such as N-BUTYL-4,4-DI-(TERT-BUTYLPEROXY)VALERATE, are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides.

| Brandbekämpfung | Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]:SMALL FIRE: Water spray or fog is preferredif water not available use dry chemical, CO2 or regular foam.LARGE FIRE: Flood fire area with water from a distance. Use water spray or fogavoid aiming straight or solid streams directly onto the product. Do not move cargo or vehicle if cargo has been exposed to heat. If it can be done safely, move undamaged containers away from the area around the fire.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. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzlesif this is impossible, withdraw from area and let fire burn. (ERG, 2024) |

| Erste Hilfe | Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]:Refer to the "General First Aid" section. Specific First Aid: Contaminated clothing may be a fire risk when dry. (ERG, 2024) |

| Freisetung ohne Brand | Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]:ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Keep substance wet using water spray. Stop leak if you can do it without risk.SMALL SPILL: Pick up with inert, damp, non-combustible material using clean, non-sparking tools and place into loosely covered plastic containers for later disposal.LARGE SPILL: Wet down with water and dike for later disposal. Prevent entry into waterways, sewers, basements or confined areas. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST. (ERG, 2024) |

| Isolation and Evacuation | Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]: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.LARGE SPILL: Consider initial evacuation for at least 250 meters (800 feet) in all directions.FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directionsalso, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024) |

| Personal Protective Equipment (PPE) | Excerpt from ERG Guide 146 [Organic Peroxides (Heat, Contamination and Friction Sensitive)]: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. (ERG, 2024) |
