Permissible Exposure Limits – OSHA Annotated Table Z-1
OELs for hundreds of additional substances have been adopted by Cal/OSHA, NIOSH, and ACGIH. These organizations periodically make revisions to their OELs and so they should be consulted directly for their most current values and substances, as well as special notations such as for skin absorption.
TLV Chemical Substances Introduction - ACGIH
Four categories of TLVs ® are specified: time-weighted average (TWA); short-term exposure limit (STEL); surface limit (SL); and ceiling (C). For most substances, a TWA alone or with a STEL is relevant. For some substances (e.g., irritant gases), only the TLV–STEL or TLV–C is applicable.
【摘要 】 目的将我国职业卫生标准GBZ 2.1 中规定的与ACGIH 于2013年发布的化学有害因素职业接触限值(OELs)数量 、水 平、制 定和管理过程等方面进行系统比较,并提出我国职业卫生标准制修订过程中优先考虑的化学物质OELs 及有关建议, 为制定职业卫生标准规划计划提供基础数据和参考。

职业接触限值(OELs)小百科_合规化学网
2017年4月10日 · 职业接触限值((Occupational exposure limit values,简称OELs)是指劳动者在职业活动过程中长期反复接触,对绝大多数接触者的健康不引起有害作用的容许接触水平。 通常分为化学有害因素的职业接触限值以及物理因素职业接触限值。 在本期解读中我们所指的 OELs特指化学有害因素的职业接触限值。 2)分类. 在GBZ 2.1-2007中,化学有害因素的职业接触限值包括时间加权平均容许浓度、短时间接触容许浓度和最高容许浓度三类。 具体定义如表1所示。 …
职业接触限值 occupational exposure limits;OELs 劳动者在职业活动过程中长期反复接触某种或多种职业性有害因素,不会引起绝大多数接触者不良 健康效应的容许接触水平。
職業接觸限值 - ILO Encyclopaedia of Occupational Health and Safety
美國政府工業衛生學家會議 (ACGIH) 每年發布的限值或指南已逐漸成為美國和大多數其他國家/地區最廣泛接受的限值或指南,稱為閾值限值 (TLV)(LaNier 1984 ;庫克 1986 年;ACGIH 1994 年)。

Permissible Exposure Limits - Annotated Tables | Occupational …
OSHA has chosen to present a side-by-side table with the Cal/OSHA PELs, the NIOSH Recommended Exposure Limits (RELs) and the ACGIH ® TLVs ® s. The tables list air concentration limits, but do not include notations for skin absorption or sensitization. OSHA's mandatory PELs in the Z-Tables remain in effect.
我国职业接触限值与美国政府工业卫生师协会阈限值的比较
美国政府工业卫生师协会(ACGIH)制定并定期更新的阈限值(TLVs)在世界范围内被广泛采纳和引用,也是我国职业接触限值(OELs)的重要参考,有必要定期对其进行追踪并与我国OELs进行比较。 对GBZ 2.1—2019《工作场所有害因素职业接触限值 第 1 部分:化学有害因素》(以下简称“GBZ 2.1—2019”)中的OELs与ACGIH制定的TLVs(2024)进行比较研究,为我国后续OELs制修订提供参考。 GBZ 2.1—2019 中的OELs与ACGIH发布的 TLVs采用Microsoft Excel …
