What precautions should the analysis laboratory take during the rainy season?
Thread Content
The rain keeps falling non-stop, having a negative impact on both work and mood. In such conditions, what aspects should be taken into consideration when working in an analysis room?
Pay attention to the electrical safety of instruments and equipment, and be careful to keep samples dry during weighing.
1. Remember to bring a raincoat and an umbrella when going to and from work; it’s best to have a pair of rain boots as well； 2. To avoid heavy rain at noon, it’s best to go to the cafeteria earlier during lunch time; it’s okay to do less work, but one must not go hungry ； 3. Don’t use your phone by the window when it’s raining, as that will excite Lord Thunder ； 4. Those who pick up their children need to be extra careful; if it seems like it’s going to rain before work ends, ask for leave early or skip work, so as not to bother the kindergarten teacher ； 5. For work-related matters, refer to what other friends have shared.
Issue to note 1: Temperature control of the sampling leads – adjust the amount of heating steam supplied to these leads. 2. Ensure good indoor hygiene control to avoid dirt and clutter. 3. Protect the signal cables to prevent water ingress. 4. Waterproofing treatment for the four walls of the analysis room. 5. Check that the lightning protection devices in the analysis laboratory are in good condition.
1. Protection against lightning. Check that the grounding is in good condition ； Electronic instruments and electrical equipment should be kept away from thunderstorms as much as possible. 2. Moisture and mold resistance. The air is humid, so medicines and reagents are prone to absorbing moisture and becoming moldy; ensure proper ventilation and dryness. 3. Testing should be carried out promptly to prevent the samples from deteriorating. 4. Before weighing, measuring instruments, beakers, etc. must be dried. 5. The retained samples should be sealed promptly. 6. When electrical devices are not in use for an extended period, the power supply should be disconnected, and the devices should be powered on periodically to run without a load for some time ； Laboratory technicians should preferably use insulated tools when operating.
