编辑同志：现就一职工的工伤认定问题向你们咨询，盼请解答。该名职工是护场员，在护场过程中闲着无聊，爬到场内一破损的石棉瓦厂房上眺望，结果石棉瓦断裂，该职工掉了下来，造成腰椎骨两节粉碎性骨折。该职工受过“三级”安全教育，破旧的石棉瓦屋面又不是他该去的地方。请 Edit Comrades: Now on the issue of a worker’s injury identified to you, I hope to answer. The worker was a protector who was bored in the care of the guard and climbed onto a damaged asbestos plant on the site. As a result, the asbestos was broken and the worker fell off, resulting in two comminuted fractures of the lumbar spine. The worker was educated with “three levels of safety education” and the shabby asbestos roof was not where he should go. please
