Existing heat stress risk management guidelines recommended by international standards are not practical for the construction industry which needs site supervision staff to make instant managerial decisions to mitigate heat risks. The ability of the predicted heat strain (PHS) model [ISO 7933 (2004). Ergonomics of the thermal environment analytical determination and interpretation of heat stress using calculation of the predicted heat strain. Geneva: International Standard Organisation] to predict maximum allowable exposure time (D lim) has now enabled development of localized, action-triggering and threshold-based guidelines for implementation by lay frontline staff on construction sites. This article presents a protocol for development of two heat stress management tools by applying the PHS model to its full potential. One of the tools is developed to facilitate managerial decisions on an optimized work-rest regimen for paced work. The other tool is developed to enable workers' self-regulation during self-paced work.
国际标准推荐的现有热应激风险管理指南对于建筑行业并不实用，因为该行业需要现场监督人员做出即时管理决策以减轻热风险。预测热应激（PHS）模型[ISO 7933（2004年）。热环境人类工效学——通过预测热应激计算来分析确定和解释热应激。日内瓦：国际标准化组织]预测最大允许暴露时间（Dlim）的能力，现已促成制定本地化、行动触发和基于阈值的指南，供建筑工地的一线非专业工作人员实施。本文介绍了一种通过充分发挥PHS模型的潜力来开发两种热应激管理工具的方案。其中一种工具旨在促进针对节奏性工作制定优化的工作休息制度的管理决策。另一种工具旨在使工人在自主节奏工作期间能够自我调节。
