What is the primary concern when dealing with organic peroxides?

Organic peroxides are compounds that contain a peroxide functional group and are known for their reactive nature. The primary concern when dealing with these substances is their potential to behave as significant fire and explosion hazards. Organic peroxides can undergo exothermic decomposition, which can lead to rapid release of oxygen and heat, triggering combustion or explosions if not handled correctly.

The reactivity of organic peroxides makes them particularly dangerous under certain conditions, such as exposure to heat, light, or contaminants. This characteristic requires stringent safety measures during storage and handling to prevent accidents. Understanding this risk is critical for maintaining a safe working environment and ensuring that proper protocols are followed to mitigate fire and explosion hazards associated with these chemicals.

While the other concerns listed, such as possible allergic reactions or pleasant odors, may be relevant in different contexts, they do not capture the primary safety issues that professionals encounter with organic peroxides in a construction or industrial setting.
