AD817 Maximum Power Supply Operating Range


I am looking to get some clarification on what the safe maximum power supply operating range is for the AD817 operation amplifier. On page one of the datasheet the power supply range is specified to be between +/-5V and +/-15V. However, under the Power supply operating range I see +/-18V is listed as a max value and that +/-18V is also listed as an absolute maximum value. Is it safe to operate the op-amp with a difference of 36V between the two rails or should I stay away from this maximum value?
