After the installation of lead doors for hospitals, further radiation protection detection must be conducted, and the operation of the doors should be checked for smoothness and whether they can be properly guided to function. Below are the precautions for installing and using lead doors: 1. Ensure proper installation according to specifications During installation, the door should be placed into the opening, ensuring the edge fits tightly against the wall and is perpendicular. In necessary cases, correct the wall surface to ensure a stable installation as per regulations. 2. Verify the smooth operation of the doors during initial installation The doors should close tightly during staff operations to ensure the safety of all personnel inside and outside. Therefore, during the initial installation, check if the lead door operates smoothly to avoid potential harm to individuals due to the door not closing completely. 3. Handle the lead door gently During daily use and operation of the lead door, handle it gently. Especially when the door does not close normally for an unknown reason, do not force the door open or close to avoid damaging the door and potentially causing radiation leakage. 4. Pay attention to regular maintenance during use Maintenance of the lead door should not be overlooked. Even though it is made of corrosion-resistant metals like stainless steel and lead, it is still important to avoid contact with corrosive liquids during daily use. Additionally, ensure the normal operation of the track, automated control components, and sensors to prevent personal injury due to component failure.
