Axe operation conditions
2.1 Before the axe is made, it's essential to complete the structural acceptance process first. Certain types of work such as hydropower installation, ventilation setup, and equipment mounting should be carried out in advance, ensuring that all water supply systems are fully installed and functional. 2.2 When working on steps and door and window frames, make sure the doors and windows are properly framed and securely fixed. The edges of the frame should be sealed or stitched for stability. For aluminum alloy door and window frames, it's recommended to apply a protective film and seal the joints according to the design specifications to prevent dirt accumulation and rusting. 2.3 Based on the design drawings, mark the horizontal elevation lines and the central axis of the column. Set up scaffolding in advance, using a double-row scaffold system. Ensure that the horizontal and vertical poles are kept at least 150–200 mm away from walls, door, and window corners. The step height must meet the construction standards and safety requirements. 2.4 Clean the wall surface thoroughly before starting any work. Fill in any holes left by scaffolding, and construct the window sill and window cover to ensure a smooth and stable base for subsequent processes. 2.5 Before using gravel, sieve it to remove dust and impurities, and clean it thoroughly to ensure it meets the required quality standards for construction use. 3. Operating Process
Human Monkeypox Virus (MPV) Antigen Rapid Test Device (colloidal gold) is an in vitro diagnostic test for the qualitative detection of human monkeypox virus antigens in Nasopharyngeal swab,saliva and exudate of blain using the rapid immunochromatographic method. The identification is based on the monoclonal antibodies specific for the human monkeypox virus antigen. It will provide information for clinical doctors to prescribe correct medications.
