「英中对照」WorkersCompensation.com工伤赔偿专家克莱尔·马塞尔曼提示：气温下降时设施内一氧化碳暴露风险上升

As seasonal temperatures cool, facility managers should ensure air monitoring equipment is properly calibrated in areas where people work next to forklifts, generators and other combustion equipment, says Claire Muselman, chief operating officer at WorkersCompensation.com.  随着季节性气温下降，设施经理应确保在叉车、发电机和其他燃烧设备附近有人作业的区域妥善校准空气监测设备，Claire Muselman 表示，她是 WorkersCompensation.com 首席运营官。  

Carbon monoxide is colorless and odorless, so as the weather cools and doors and windows are closed and heaters turned on, CO concentrations can increase in rooms without adequate ventilation, Muselman says in a blog post. 一氧化碳无色无味，因此随着天气转凉、门窗关闭且取暖器开启，通风不足的房间内 CO 浓度可能会升高，Muselman 在一篇博文中表示。 

“Occupants adapt quickly to … environmental conditions, making gradual deterioration difficult to judge from inside the space,” says Muselman, whose company provides worker resources for filing occupation-related insurance claims. “室内人员会很快适应……环境条件，这使得人们难以在空间内部判断环境的逐渐恶化，”Muselman 表示，她的公司为工人提供提交职业相关保险索赔的资源。 

Muselman pointed to a study by the National Institute for Occupational Safety and Health that found combustion equipment was a major factor among workers who died from CO exposure. Motor vehicles were the most common source, followed by heating systems and generators.Muselman 提到 National Institute for Occupational Safety and Health 的一项研究，该研究发现，在死于 CO 暴露的工人中，燃烧设备是一个主要因素。机动车辆是最常见来源，其次是供暖系统和发电机。

Because exposure can go unnoticed, managers that don’t have monitoring equipment working properly risk exposing their crews to unhealthful conditions. “A cluster of employees reporting headache, dizziness, nausea, unusual fatigue, or confusion in the same area should immediately raise an environmental question,” she said.由于暴露可能在无人察觉的情况下发生，未能让监测设备正常运行的经理可能使其团队暴露于不健康的环境中。“同一区域若有多名员工报告头痛、头晕、恶心、异常疲劳或意识模糊，应立即提出环境方面的疑问，”她表示。

Indoor air quality risk increases in office environments as well when the weather cools, says Muselman, pointing to a National Institutes of Health study attributing 35% of sick leave to poor ventilation when exposure to outdoor air is reduced. “Ventilation can have measurable organizational consequences beyond whether a room feels comfortable,” she said. Muselman 表示，天气转凉时办公环境的室内空气质量风险也会增加。她提到 National Institutes of Health 的一项研究，该研究将35% 的病假归因于通风不良，此时室外空气暴露减少。“通风除了影响房间舒适感之外，还可能产生可衡量的组织后果，”她表示。 

Not all indoor air quality issues are urgent. Poor ventilation can increase exposure to airborne contaminants and moisture problems can lead to mold growth over time, but exposure to CO from combustion equipment requires immediate action, she says.  并非所有室内空气质量问题都很紧急。通风不良会增加对空气传播污染物的暴露，潮湿问题久而久之会导致霉菌生长，但暴露于燃烧设备产生的 CO 需要立即采取行动，她表示。  

“CO binds to hemoglobin with far greater affinity than oxygen, interfering with the body's ability to deliver oxygen to the brain, heart, and other tissues,” she said. “Exposure can produce headache, dizziness, weakness, nausea, confusion, and fatigue before a worker recognizes an emergency.”“CO 与血红蛋白结合的亲和力远高于氧气，会干扰身体向大脑、心脏和其他组织输送氧气的能力，”她表示。“在工人意识到发生紧急情况之前，暴露就可能引发头痛、头晕、虚弱、恶心、意识模糊和疲劳。”

In addition to ensuring monitoring equipment is operating properly, managers should familiarize their workers to exposure risk.除确保监控设备正常运行外，管理人员还应让工人熟悉暴露风险。

“Employees working around combustion equipment should know where monitors are located, what alarms mean, and how to respond,” she said.“在燃烧设备附近工作的员工应知道监测仪位于何处、警报意味着什么，以及如何应对，”她说道。
