What is a characteristic of pyrotechnic materials?

The characteristic of pyrotechnic materials that requires protective packaging is important for ensuring safety during storage and handling. Pyrotechnic materials, which can include things like fireworks, flares, and ammunition, are sensitive to heat, friction, and shock. Proper packaging is essential to prevent accidental ignition or reaction, as these materials can easily be set off if subjected to inappropriate environmental conditions or physical stresses. Protective packaging also helps to contain any potential hazards and reduces the risk of exposure to people and the environment. This ensures that the pyrotechnic materials remain stable and safe until they are intentionally used.
