Most chemical occupational-disease hazards were low to the limit of GBZ2-2002 except lead smoke and carbon monoxide in front of the furnace. The noise of most workplaces was classified as 0 except those above Ⅰ at some workplaces like grinding, granule-making, etc. The hot working environment of the furnace was classified as Ⅵ, other hot working environments were classified asⅠ.

除炼铁厂炉前铅烟、一氧化碳个别点超标外，其他化学性职业病危害皆未超过接触限值；除个别岗位如破碎、制粒等噪声作业分级为Ⅰ级以上外，大部分作业点噪声作业分级为0级；炼铁厂炉前高温作业为Ⅵ级，其他热源岗位为Ⅰ级。
