Throughout the history of occupational health risk control, ventilation has been implemented widely as a tried-and-true method to reduce exposure intensity to airborne contaminants. Proper determination of the ventilation rate merits careful consideration when addressing concerns directed toward occupational health and indoor air quality in commercial buildings, albeit this does not translate well among the current engineering and scientific community. This article aims to facilitate a better understanding and proper determination of ventilation rates as a countermeasure for occupational health risk control. To that end, guidance is provided to select the appropriate ventilation rate for nonpandemic versus pandemic scenarios in terms of pertinent regulatory/professional codes and mathematical modeling tools. Limitations and assumptions of the models are summarized to facilitate proper application. Furthermore, the emerging DNA-based aerosol tracing technology, which helps to verify ventilation efficacy, is discussed.

职业健康风险控制中通风率的整体认识

纵观职业健康风险控制的历史，通风作为一种行之有效的减少空气污染物暴露强度的方法已被广泛实施。在解决针对商业建筑的职业健康和室内空气质量的问题时，需要仔细考虑通风率的正确确定，尽管这在当前的工程和科学界中并没有很好地转化。本文旨在促进更好地理解和正确确定通风率作为职业健康风险控制的对策。为此，提供了指导，根据相关监管/专业规范和数学建模工具，为非流行病和流行病场景选择适当的通风率。总结了模型的局限性和假设，以方便正确应用。此外，还讨论了新兴的基于 DNA 的气溶胶追踪技术，该技术有助于验证通气效果。
