Standard Terminology Relating to Occupational Health and Safety
SCOPE
1.1 This terminology standard provides a compilation of consensus definitions of terms used in ASTM occupational safety and health standards.
1.2 This terminology standard does not purport to be an exhaustive lexicon. Rather it defines terms relevant to occupational health and safety.
1.3 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.
1.4 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope
1.1 The terms in this standard are used in the fields of occupational health and of safety. The terms are used to describe the limits
of exposure under different conditions, the meanings of terms used in describing events and the types of items measured. They will
commonly be used to express the effect of an event or the limit of a chemical exposure on human beings. This terminology standard
provides a compilation of consensus definitions of terms used in ASTM occupational safety and health standards.
1.2 This terminology standard does not purport to be an exhaustive lexicon. Rather it defines terms relevant to occupational
health and safety.
1.3 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
