Caustic substances, also known as corrosives, are materials that can damage or destroy living tissue and other materials through chemical reactions. Common examples include strong acids like sulfuric acid and bases like sodium hydroxide. These substances can cause severe burns, and their effects can be immediate upon contact. When handling caustic materials, safety precautions are essential. This includes wearing protective gear such as gloves and goggles to prevent skin and eye contact. Proper storage and disposal methods are also crucial to minimize risks to health and the environment, as spills can lead to hazardous situations.
