Different rescuers are used depending on the type of fire. When spraying the revival agent, the gaseous resurrector evaporates quickly and achieves the intended revival. When spraying gas revitalizer, the maintenance area is completely sealed; after revival, the sprayed gas remains in the maintenance zone. Entry poses life-threatening risks, and harmful gases from the protected area are released outdoors. Ventilation can be described as natural or mechanical ventilation.
1. Basement (without external windows) maintenance area and above-ground maintenance area without windows or with fixed window sashes have no natural ventilation conditions,Installation of electromechanical equipmenta mechanical exhaust system should be installed. The maintenance area should be ventilated more than four times per hour, with exhaust vents set within 460mm above the ground.
2. Set a local starter switch in a convenient location outside the maintenance area.
3. Before spraying gas revitalizer, proactively seal vents, air outlets, fire dampers, etc.
4. The mechanical exhaust device should be installed in the storage container room in the basement (without external windows), and the exhaust outlet should be directly connected outdoors.
5. The maintenance area should have a pressure relief opening, and the pressure relief opening area should be calculated based on the jet speed of the rescuer.
Common issues in Qingdao electromechanical equipment installation projects include:
After revival, rooms using gas revival systems will emit toxic and harmful gases.
1. Basement (without external windows) maintenance area, above-ground maintenance area without windows or fixed window sashes, or gas cylinder room without a mechanical exhaust system.
2. Set up the exhaust system, but set on-site start switches in locations outside the maintenance area that are difficult to operate.
3. Before spraying the revivant, ventilation and air conditioning pipelines can be electrically sealed.
4. Pressure relief vents are not set up in the maintenance area according to regulations.
Before starting the electromechanical equipment installation project, preparations must be made before construction, and materials should be neatly arranged after entering the site.
During material handling, pay attention to not damaging the materials and ensure personal safety, using helmets, gloves, and labor protection shoes; After the materials are moved, engineers provide on-site guidance and arrange the construction sequence for the construction personnel. ExistElectromechanical equipment installation projectsDuring construction, the sequence determines the key factors in project quality and efficiency.
