Third question
An enterprise has a glassware production workshop. The glassware manufacturing in this enterprise is divided into three main processes: firing molten glass, blow molding and annealing. The main equipment for firing molten glass is glass melting furnace. During firing, quartz sand (silicon dioxide), soda ash (sodium hydroxide), arsenic trioxide and other raw materials are manually added from the top side, and heavy oil and gas are used as fuels to burn to 1 300℃ ~ 1 700℃, and the glass melt is discharged from the bottom side.
The glassware workshop is a reinforced concrete frame structure, and the roof is a cement precast slab. There is a 1 46 t glass melting furnace in the workshop, with a height of 6 m. The top of the furnace is away from the workshop steel beam 17m, and the bottom of the furnace is away from the ground 15 m. 3m away from the furnace outlet is an automatic glassware blowing molding machine and an annealing furnace. The linear distance between the gas pressure regulating station and the workshop is 15 m, the linear distance between the heavy oil storage tank and the workshop is 15 m, and there are 20 indoor staff.
Due to the extended service of the molten pool furnace, the refractory bricks in the arch of the furnace top were damaged, and the flame rushed out of the furnace top near 1m, and the refractory bricks on both sides of the furnace.
It has also been deformed, and the furnace may collapse at any time.

City Emergency Office immediately reported to the city leaders, who instructed to start the emergency rescue plan for major hazardous chemical accidents in C city. According to the requirements of the plan, the Municipal Emergency Office informed relevant departments, rescue teams and expert groups to rush to the scene of the accident immediately. When the city leaders arrived at the scene of the accident, the fire brigade was plugging and controlling the leakage, and the medical staff were rescuing the injured. After briefly listening to the report of the main person in charge of a petrochemical plant, the city leaders instructed to set up the on-site emergency rescue headquarters and take corresponding emergency measures. In order to reduce the impact, the neighboring chemical plants were not notified. 16: 30, at the end of the on-site drill, the city leaders made an oral summary at the headquarters and announced the end of the drill.
