Exposure Limit Regulations and Safety Standards 

Safety standards are in place to protect your business and the health of your employees. Leading companies are choosing to exceed industry standards and double down on safety with ChemDAQ’s monitoring solutions.

Permissible Exposure Limits 

Multiple government agencies and private organizations have set limitation guidelines for workers exposed to Peracetic Acid, Hydrogen Peroxide and Ethylene Oxide.

*Short Term Exposure Limits: The 15-minute Time Weighted Average (TWA) is 2 ppm in the UK and Hawaii, 3 ppm in Washington, and either 2 ppm or 3ppm in Canada based upon province.


*Excursion Limits: Worker exposure levels can’t exceed more than 3 ppm for more than 30 minutes a day and at a ceiling level of 5 ppm, according to ACGIH.

Go Beyond Regulations to Lower Health Risks

Employees who are overexposed to high concentrations of sterilant chemicals can develop serious health problems. Our gas detection monitoring solutions measure and alert workers in real-time when chemical vapors in the air exceed safety levels. 



How is Workplace Safety Mandated?

Occupational Safety and Health Administration (OSHA) has legal authority to regulate, monitor, and inspect workplaces. 

According to Act 8 of the OSH Act of 1970, OSHA “is authorized to –

1. enter without delay and at reasonable times any factory, plant, establishment, construction site, or other area, workplace, or environment where work is performed by an employee of an employer; and

2. inspect and investigate during regular working hours and at other reasonable times, and within reasonable limits and in a reasonable manner, any such place of employment and all pertinent conditions, structures, machines, apparatus, devices, equipment, and materials therein, and to question privately any such employer, owner, operator, agent or employee.”


The General Duty Clause describes how employers must provide a safe work environment for their employees.


The Hazard Communication Standard describes how employers must inform their employees about the chemical hazards they work with. 


Section 17 of the OSHA Act gives OSHA
permission to issue citations and fines for not following these Clauses and Standards.

    The General Duty Clause

    Section 5(a)(1) of the OSHA Act was formalized in 1970 stating: “Each employer shall –

    1. furnish to each of his employees’ employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees.

    2. comply with occupational safety and health standards promulgated under this Act.”

    Conversely, under 5(b) “Each employee shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct.”  

    The Hazard Communication Standard

    This standard was established by OSHA in 1974 and was most recently updated in 2019. It states that “to ensure chemical safety in the workplace, information about the identities and hazards of the chemicals must be available and understandable to workers.” 


    The standard includes:

    • Employees must classify hazards

    • A written hazard communication plan

    • Chemical must be labeled, including chemical hazards, precautionary statements, and pictograms

    • Provide Safety Data Sheets

    • Supply personal protective equipment 

    • Provide safety training on 

      • the hazards of the chemicals, 

      • how to detect the presence or release of a hazardous chemical in the work area

      • symptoms of overexposure 

      • measures employees should take to protect themselves

                                ChemDAQ can help your company exceed industry safety standards.
