A unique profession
A friend related to the storage and transportation of flour told the story.
Since the flour suspension in the air is explosive, Rostechnadzor requires that the doors of the warehouse be opened inside - then a possible explosion will damage less what is outside. Otherwise a large penalty.
Firefighters require the doors to be opened out, then people on the fire hazardous facility have more chances to escape. It is also a huge fine.
As a result of this collision, one of the most important areas of activity of the security service of one of the Russian grain companies was to find out when the next inspection will come and from which supervisory agency.
And in the regular schedule appeared a unique work specialty - an emergency door hanger.
