This video is interesting on many levels and since it occurred outside of the USA I am not sure about any regulatory issues in the home country, but if this were in the USA we can see a number of issues. However, this video shows us the conditions under which we might respond to an ammonia leak. Climbing the tanker truck ladder in a LEVEL A suit under a blanket of fire water raining down on you are some conditions we may want to train under as they are quite common for an NH3 leak.
