Depends on the foam. Styrene board will not outgas like the urethanes do.
Styrene foam is the same material used in meat trays and coffee cups,
except
that they add bromides for fire resistance.

What is the pink and blue board. I still hear about carpet, glues,
many things from oil can be of concern when new.

The pink, blue, and yellow is extruded polystyrene board.

Poly as in polyurethane, so it outgasses.
