§ 29421 Subcontainer Definition

• •A 'subcontainer' is like a smaller box or bin inside a bigger box.
• •It helps organize stuff inside the main container.
• •This rule was made in 1967.

You have a big toolbox, and inside it, you keep small plastic bins for screws, nails, and bolts.

Those small plastic bins are called 'subcontainers' because they are smaller boxes inside the big toolbox.
