To transport self-reactive substances they must be:

• A. Temperature Controlled
• B. Pressurized
• C. Insulated
• D. Ventilated

Answer: (A)

Self-reactive substances can undergo self-heating and decompose violently if their temperature rises. To prevent this during transport, they must be kept within a controlled temperature range. Temperature control directly reduces the risk of a runaway reaction by keeping the material from reaching conditions that trigger decomposition. While insulation or ventilation might be relevant in some packaging designs, they do not address the primary hazard as effectively as actively maintaining the correct temperature.
