Abstract: The invention relates to a safety container arrangement (10) for holding hazardous liquids, especially an organic peroxide (OP). It is envisaged, according to the invention, that the safety container arrangement (10) has receiving spaces (12, 14) separated from one another, of which at least one first receiving space (12) serves for holding the hazardous liquid (OP) and at least one second receiving space (14) serves for holding another liquid (V) miscible with the hazardous liquid (OP) for lowering the potential risk, especially a liquid (V) for diluting and/or neutralizing the hazardous liquid (OP). At least one connection (106) is provided between the receiving spaces (12, 14), which is closed by at least one safety mechanism (16), which in the case of danger releases the at least one connection (106) and permits mixing of the liquids (OP, V).
