The current arrangement was designed to reflect the flammability dangers of anhydrous ammonia but failed to capture the toxic dangers of anhydrous ammonia. The safety sheet issued to the vessel stated that the short term exposure limit was 25 ppm. Current flammable detection would alarm when there was approximately 25,000 ppm of anhydrous ammonia in the space. 74 SOLAS (14) VII/13.1 IGC (93) 12.6.1
