Nitro-glycerins, also known as nitroglycerines, are highly explosive and unstable substances used in various applications such as the manufacture of explosives and propellants, medicine, and as a component in rocket fuel. Similar to nitro-glycerins, dynamites and other high explosives like TNT and C4 are stable and potent in their destructive power. Explosive compounds like nitro-glycerins are often used in mining or construction and require careful handling and storage to prevent accidental detonations. Excessive exposure to nitro-glycerins can cause severe headaches and dizziness, leading to other health problems. While nitro-glycerins are useful in many applications, it is essential to use proper protective equipment and follow safety procedures thoroughly.
