To which class do aluminum, fireworks, dynamite, and nitroglycerin belong?

Aluminum, fireworks, dynamite, and nitroglycerin all belong to Class 1 Explosives due to their nature and behavior in terms of hazard classification. Class 1 includes materials that are explosive or highly dangerous when subjected to fire or shock.

Aluminum is often used in combination with other substances to enhance the explosive properties of fireworks and dynamite; it acts as a fuel in these systems. Fireworks are a specific type of explosive designed for visual and auditory effects, thus inherently classified under this category. Dynamite and nitroglycerin are both high explosives, with nitroglycerin being a sensitive explosive compound that can detonate easily under various conditions. The classification is crucial for safety regulations and proper handling of these materials, as they pose significant risks due to their potential for rapid energy release.

Understanding this classification helps in recognizing the safety protocols required when dealing with these substances.
