溫故知新之咩叫 懸空式竹棚架（俗稱 「吊棚」/「飛棚」）
November 5, 2024
懸空式竹棚架（俗稱 「吊棚」）是竹棚架 的一種。吊棚一般以狗臂架結構承托，是從樓宇或構築物外牆伸出的懸空結構，而整個棚架全靠現存樓宇或構築物作支撐。 常見的懸空式竹棚架是由以 3 顆繫穩螺絲垂直安裝的金屬托架從底部承托（下稱「一般 懸空式竹棚架」）。 2024 年職安知識您要知: 勞工處已出版更新的「竹棚架工作安全守則」 Reference: https://www.oshc.org.hk/oshc_data/files/greencross/2024/GXAPR-JUN2024-05.pdf https://www.labour.gov.hk/tc/public/pdf/os/D/TOS_Guidance_notes_tc.pdf
溫顧知新: 棚架安全 competent person (CP):
June 3, 2024
好多有關棚架的RA其實都好似忽略左 “改” 呢一PART, 同埋其實又真係幾何有個CP企係到睇…呢個我心中有問號…不過都可以review 下 CP 在搭棚上既職責: 3.2 Construction Sites (Safety) Regulations 3.2.6 Regulation 38F This regulation requires that a scaffold shall not be used unless it has been inspected by a competent person (CP): (a) before being taken into use for the first time; (b) at regular intervals not exceeding 14 days immediately
