Exposure Limits for Ethylene Oxide

Guidelines for Ethylene Oxide Permissible Exposure Limits

When using Ethylene Oxide in the workplace, it’s imperative to follow safety guidelines and worker exposure limits set by these national agencies. 

OSHA General Duty Clause

Section 5(a)(1) of the OSHA Act – otherwise known as the General Duty Clause – was formalized in 1970 to enforce workplace safety standards. The General Duty Clause states: 

  • Employers have a legal duty to provide a safe work environment free from hazards

  • Employees have the right to a safe work environment

  • OSHA can issue citations and fines for not following the required permissible exposure limits

Hazard Communication Standard

The Hazard Communication Standard outlined in the OSHA Act was designed to ensure employers and suppliers use chemicals such as Ethylene Oxide safely in the workplace.

  • Communicate all hazard regulations with labels

  • Provide Ethylene Oxide Safety Data Sheets (SDS)

  • Share best practices

  • Implement safety training

  • Supply personal protective equipment (PPE)

A standard set of pictograms developed by the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) and adopted by OSHA is used in the workplace to quickly communicate hazards to employees.
