Vermiculite insluation itself does not burn: it is non-combustible, though contaminants and debris, if mixed with any insulating material at enough volume, might burn. When wet, vermiculite can hold a lot of water, as much as 220-325% by weight, and as much as 20-50% by volume.

Does vermiculite need to be removed?

There is no reason to avoid using sand, unless you will be moving the containers frequently. Sand adds a considerable amount of weight but IMO does a better job at aeration than perlite/vermiculite.

Does vermiculite aerate soil?

Since vermiculite acts like a sponge and absorbs more water than perlite, it doesn't aerate the soil as well. This means less oxygen for plant roots. If you use it when growing plants that don't need damp soil, you might find your plants suffering from root rot.
