Laboratory Safety Management System
The installation and use management of electrical equipment in the laboratory must comply with the management regulations for safe use of electricity. Special lines must be used for high-power experimental equipment, and it is strictly forbidden to use common lighting lines.
1. Special equipment
01 Pressure equipment
(1) Pressure equipment needs to be inspected regularly to ensure its safety and effectiveness. The pressure vessels that have been inactive for a long time must be inspected by the special equipment management department before they can be used.
(2) The pressure equipment practitioners must be trained, hold certificates, and operate in strict accordance with the regulations. When in use, personnel must not leave.
(3) After the work is completed, it is not allowed to deflate and decompress, and the lid can only be opened after the pressure in the container has dropped to equal to the atmospheric pressure.
(4) If any abnormal phenomenon is found, stop using it immediately and notify the equipment manager.
02 Gas cylinder
(1) The user must ensure that the quality of the purchased gas cylinders is reliable, the labels are accurate and intact, and the cylinders are for special use, and the steel stamp and color marking of the gas cylinders are not allowed to be changed without authorization.
(2) Open flames are strictly prohibited in the storage place of the gas cylinder, keep it ventilated and dry, and avoid direct sunlight. For places involving toxic, flammable and explosive gases, necessary gas leakage detection and alarm devices should be equipped.
(3) Gas cylinders must be kept away from heat sources, fire sources, flammable, explosive, and corrosive materials, and stored in separate categories. They must not be mixed, and must not be stored in corridors and public places. It is strictly forbidden to store oxygen, acetylene gas, grease, and flammable materials together, and the valve port must not be contaminated with oil or grease.
(4) There should be a certain residual pressure in the empty bottle, which should be placed separately from the full bottle and clearly marked.
(5) Gas cylinders must be placed upright and properly fixed to prevent falls. Do a good job of marking the gas cylinders and gas pipelines. When there are multiple gases or multiple pipelines, it is necessary to draw up a detailed gas supply pipeline diagram.
(6) When opening the steel cylinder, first open the main valve, and then open the pressure reducing valve. When closing the steel cylinder, close the main valve first, and then close the pressure reducing valve after exhausting the remaining gas. Do not only close the pressure reducing valve, not the main valve.
(7) Before and after use, check the gas pipelines, joints, switches and appliances for leakage, confirm the type of gas contained, and make emergency preparations for possible emergencies.
(8) Use a trolley to move the gas cylinder, and never drag, roll or slide the gas cylinder. It is strictly forbidden to knock and collide with gas cylinders.
(9) If gas leakage is found, emergency measures such as shutting off the gas source, opening windows for ventilation, and evacuating personnel should be taken immediately. Do not switch the power supply when flammable and explosive gas leaks.
(10) Expired, uninspected and unqualified gas cylinders shall not be used.
