The MGM Grand Hotel is located in Las Vegas, USA. The MGM Grand Hotel was built in 1973 and opened in December of the same year. The 26-storey hotel covers an area of 3,000 square meters, with 2,076 guest rooms, a 4,600-square-meter casino, a 1,200-seat theater, 80 restaurants catering to 11,000 people and a department store. Hotel facilities luxury, exquisite decoration, is a magnificent modern hotel.

At about 7:10 a.m. on November 21, 1980, a fire broke out in the "Dailey" restaurant (adjacent to the casino on the first floor). Water cannon was used to put out the fire but failed. Due to the large number of combustible plastics, paper products and decorations in the restaurant, the fire spread quickly and soon the restaurant became a sea of fire. Without a fire partition, the fire quickly spread to an adjoining casino. At 7:25 a.m., the entire casino went up in flames. A large number of flammable decorations, plywood, foam cushion and so on emit toxic smoke in the combustion. After the fire, the air conditioning system in the hotel was not turned off, and the smoke diffused everywhere through the air conditioning duct. Fire and smoke spread upward through stairwells, elevator shafts and various vertical holes and crevices. In a very short time, smoke filled the hotel building. More than 5000 people were in the hotel when the fire broke out. Because there was no alarm, the guest room did not discover the fire in time. Many people did not know there was a fire until they smelled the smell of burning, saw the smoke or heard the sound of knocking on the door, broken glass and helicopters. Some people were evacuated from the building in time, while others were trapped inside. Many people, wearing pajamas, rushed to the roof with their belongings and waited for helicopters to rescue them. Some passengers have died because the stairwell doors are locked and they enter a cul-de-sac. The fire brigade was alerted at 7:15, and more than 500 firefighters were mobilized to put out the fire and rescue. It took more than two hours to put out the fire. It took more than four hours to evacuate and rescue the building because there were so many people inside. Most of the victims were found to have died of asphyxiation caused by smoke poisoning during the cleanup. Of the 84 fatalities, 64 died on the upper floors of the hotel, most of them on the 21 to 25 floors; Of the 64, 29 died in the rooms, 21 in the hallways or elevator halls, five in the elevators and nine in the stairwells. The fire eventually caused the 4600 square meters of large casino interior decoration, appliances and "Daley" restaurant as well as many public room decoration, furniture and other property was destroyed, 84 people died, injured 679 people.

After the disaster, people deeply reflect on the importance of building fire prevention for people's life safety and property loss. More attention has been paid to building fire prevention, fire alarm system and active fire extinguishing system in various fields. At this time, fire prevention and plugging system was really paid attention to until today, when important standards and standards were formed.

Fire-proof sealing system is sealed with fireproof plugging material cables or pipelines form hole through the wall or floor, used to seal all kinds of things, such as cable, pipe, tubing, the trachea, through the wall (warehouse) wall floor (a), the formation of the various openings and cable tray fire compartmentation, its role is to prevent the fire spread to the adjacent area of fire origin, To avoid the fire spread through these openings and gaps, smoke diffusion, to achieve the purpose of protecting personnel and equipment safety. High-end fireproof sealing products have excellent fireproof function, weatherability, structural stability, and easy capacity expansion. China has a clear national standard for fireproof sealing requirements. GB 23864-2009, stipulates the terms and definitions, classification and marking, requirements, test methods, inspection rules, comprehensive judgment criteria, packaging, marking, storage, transportation and other contents of fireproof sealing materials. The standard is applicable to fireproof sealing materials or fireproof sealing components used in various perforating holes and structural gaps of buildings, structures and various types of facilities, except for fireproof expansion seals used in the interior of building fittings and fire resistance rings of hard polyvinyl chloride building drainage pipes.

Is the basic principle of fireproof plugging plugging material in case of fire or high temperature physical and chemical reaction, expansion or ablation, seal gap left by the fuel combustion, prevent fire and poisonous gases generated in the fire and smoke spread have heat absorption and heat insulation effect, at the same time to reduce the content on the surface of the back fire temperature, prevent fire back surface fuel combustion. Because of the various buildings in the world, equipment changing with each new day, the working conditions are different, it is difficult to have a fire sealing product or system to meet all the requirements, so choose professional fire sealing products and system brand will try to meet your various needs in a comprehensive and professional way. GC has a large number of product brands for you to choose, providing you with high quality selection scheme, to meet your important needs. GC's products have been in all parts of the country, various fields have a lot of engineering cases, rich experience in application, customers are highly praised. It is your best choice for fire prevention and plugging products, and it will escort your safety.
