These Low- or No-Cost Steps Will Help Safeguard Workplaces Against the Spread of 新型冠状病毒肺炎

随着居家令解除，闲置的工作场所重新开放, everyone has a role to play in protecting themselves and others from the spread of 新型冠状病毒肺炎.

作为建筑通风和操作方面的专家, mg游戏平台 is working in partnership with clients to help as they prepare their facilities and design operations adapted to prevent the spread of the novel coronavirus.

为mg游戏平台及其客户提供指导, Chief 机械 Engineer Matt Ford condensed this list of basic recommendations for facilities operations from publications by the Centers for Disease Control (疾病预防控制中心), 世界卫生组织(世卫组织)和美国供热学会, 制冷空调工程师(ASHRAE这样).

"These are sound things that you can do at low to no cost that will safeguard your employees,福特说.

基于ASHRAE这样的建议, the following steps should be considered in the planning stage for facility re-entry.

• Increase 室外通风 (use caution in highly polluted areas); with a lower population in the building, 这增加了人均有效稀释通风.
  • 禁用按需控制通风(DCV).
  • 充分利用节能器.
  • Take care to avoid introducing unfiltered outdoor air due to dust and allergens.
  • 如果外部空气增加, take care to make sure interior humidity does not rise above 60 percent and that the proper amount of relief air is balanced within the system.
• Improve central-air filtration to MERV-13 or the highest compatible with the filter rack, 并密封过滤器的边缘，以限制旁路.
• Keep systems running longer hours, if possible 24/7, to enhance the two actions above.
• Consider portable room air cleaners with HEPA filters for spaces that cannot increase outside air or where MERV 13 filters cannot be installed.
• Consider ultraviolet germicidal irradiation (种方法), particularly in high-risk spaces. Research shows that 种方法 in both upper-room and in-duct configurations can inactivate some disease-transmitting organisms. Either of these takes time to plan and install, and shielding is needed to protect the eyes.
• Consider current filters to be contaminated and perform a filter change for all 暖通空调 equipment. Protect personnel changing them, and seal spent filters in plastic bags for disposal. Wearing masks and gloves per 疾病预防控制中心 and OSHA is recommended while performing this task.

"These 暖通空调 recommendations help in reducing the airborne transmission of the virus,福特说. “They are steps through practical ways that owners can adjust or maintain their systems with re-entry into their facilities with workers. 这给他们的员工提供了保障和安慰，他们说, 这是我们已经采取的步骤, 我们正在尽一切努力保护员工的健康.'"

最后一个建议, this one from the plumbing world: It is recommended to pour at least one gallon of water down each drain to maintain traps. 干陷阱被发现是导致2003年SARS爆发的原因之一.

就像所有的危险一样，风险可以减少，但不能消除. These recommendations will evolve as the state of knowledge about the virus and its spread advances.
