Standard Guide for Managing Heat Stress and Heat Strain in Foundries

SIGNIFICANCE AND USE
4.1 This guide is intended to describe heat management program elements that foundries use to prevent or manage heat strain and heat-related illness. Specifically, the guide:  
4.1.1 Provides an objective framework for recognizing heat stress and heat strain, and  
4.1.2 Facilitates use of best practices to manage heat exposures to minimize heat strain and prevent heat-related illness.
SCOPE
1.1 This guide is intended to establish best practices for recognizing and managing occupational heat stress and heat strain in foundry environments.  
1.2 Objectives of the foundry heat stress and heat strain management guide are as follows:  
1.2.1 Provide an objective framework for recognizing heat stress and heat strain, and  
1.2.2 Facilitate use of best practices to manage heat exposures to minimize heat strain and prevent heat-related illness.  
1.3 In this guide, procedures necessary to manage heat stress and heat strain in foundries are described.  
1.4 Key elements of this guide include definitions of heat stress and heat strain, plus techniques for recognizing, communicating, managing, and controlling heat stress and heat strain to prevent heat-related illnesses.  
1.5 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
