Some chemical products must not be stored in the same storage unit to prevent potential hazards. For example, flammable and combustible chemicals should not be stored together with oxidizing agents or reactive chemicals, as they can pose a risk of fire or explosion. Similarly, acids and bases should be stored separately to prevent the possibility of chemical reactions or releases of harmful gases. It is essential to follow proper guidelines and regulations for the storage and segregation of chemical products to ensure safety and prevent accidents.
