(a) The carriage temperature of octyl nitrates must be maintained below 100 [deg]C (212 [deg]F) in order to prevent the occurrence of a self-sustaining exothermic decomposition reaction.
(b) Octyl nitrates may not be carried in a deck tank unless the tank has a combination of insulation and a water deluge system sufficient to maintain the tank's cargo temperature below 100 [deg]C (212 [deg]F) and the cargo temperature rise at or below 1.5 [deg]C(2.7 [deg]F)/hour, for a fire of 650 [deg]C (1200 [deg]F).
