Incompatible materials should be separated unless their combined capacity is less than what?

In the context of handling incompatible materials, it is essential to follow safety regulations and guidelines to prevent hazardous reactions. The recommended practice is to separate incompatible materials to minimize the risk of accidents or dangerous chemical interactions. The standard rule often cited states that materials can be combined safely if their total capacity does not exceed 5 pounds. This threshold is established to ensure that even small quantities of incompatible substances do not pose a significant risk when mixed, providing a margin of safety and allowing for proper handling and storage procedures. This guideline helps maintain a safe working environment by ensuring that potential hazards are managed effectively.
