Review of Today’s Topics 今日课题回顾 Personal Protective Equipment 个人防护装置 Principles of Containment 封闭控制原则 Administrative elements 管理因素 Practical applications of control strategies 控制策略实际应用 Outcomes 结果 Some material released during undocking but devices available to reduce exposures to 1ug/m3 某些物质在非对接期间排放，但设备可以减少暴露至小于1ug/m3 Solution involves capital cost but docking bags are reusable and have a reasonable life 解决方案涉及资本成本，但对接袋可重复使用，并有合理的使用周期 Situation B B类情况 Similar to situation A except there is a requirement to load significantly larger quantities into a dissolving vessel 类似于A类情况，但对负载大量物质进入溶解容器瓶时有要求 Quantities can be up to 25 kg 数量可达到25公斤 Situation B (cont) B类情况（续） Reproduced with permission Situation B (cont) B类情况（续） In this case there is no chute around the man way which is used for loading but some local exhaust ventilation has been provided nearby 这种情况下，工作人员周围没有用于装载的斜槽，但一些该区域附近的排气通风的地方有 The personal protective equipment is similar to that used by the worker in Situation?A and the operating area is an open area of the workplace 个人防护设备是类似于A类情况中工人使用的的设备，操作区域是一个开放的工作场所 Situation B (cont) B类情况（续） If the approach adopted in Situation?A was applied here, the greater volumes of material involved would mean repeated small loading operations, giving rise to potentially increased exposure (in the absence of other controls) 如果A类情况采用的方法用在这里，涉及的更大数量物质将意味着重复小装载操作，从而使潜在暴露增加（在没有其他控制中） If the other extreme was considered (ie:?one large pre?weighed bag or container) it would be difficult to handle and give rise to substantial ergonomic issues 如果考虑到是另一个极端（即：一个大型预先称过重的袋子或容器） ，那么难以处理，并引起大量的人机控制相关问题 Control Strategy Implemented控制策略补充 The solution adopted was to install a drum lifter with an enclosure around the area above the discharge points 采取的解决办法是在排放点的附近区域安装一个带有密闭空间的筒形吊顶 Drum Lifter with Discharge Enclosure带排放密闭空间的筒形吊顶 Reproduced with permission 经许可转载 Other Factors 其它因素 Glove posts installed for access to remove drum lid, open liners and
