How can thermal runaway incidents be prevented in chemical processes?

• A. By limiting exposure to sunlight
• B. By maintaining appropriate temperature controls
• C. By using only water-based chemicals
• D. By increasing the amount of heat generated

Answer: (B)

Maintaining appropriate temperature controls is critical for preventing thermal runaway incidents in chemical processes. Thermal runaway occurs when a reaction generates heat faster than the heat can be dissipated, leading to a rapid and potentially dangerous increase in temperature. By implementing rigorous temperature control measures, processes can remain within safe operating limits, minimizing the risk of excessive heat buildup. This typically involves the use of cooling systems, temperature sensors, and automated control systems that can respond to changes in temperature, thus ensuring that any exothermic reactions do not escalate uncontrollably. Properly managing the temperature helps in maintaining the stability of the chemical reaction and preventing hazardous scenarios like explosive decompositions or reactions. In contrast, limiting exposure to sunlight, while it may help with certain types of chemical degradation or safety concerns, does not directly address the root cause of thermal runaway. Similarly, using only water-based chemicals does not inherently prevent thermal runaway since many water-based reactions can still experience thermal runaway if not properly managed. Increasing the amount of heat generated is counterproductive and directly contributes to the risk of thermal runaway, making it a hazardous approach in any chemical process.
