Compliance overview
Scope and applicability
This standard specifies the requirements for the selection, use, and maintenance of respiratory protective equipment (RPE) used to prevent harm from oxygen deficiency and/or airborne contaminants in workplaces. It applies to industrial environments, chemical handling, and emergency response scenarios. This standard is mandatory for all manufacturers and employers utilizing RPE in China. It does not apply to respiratory protective equipment used for underwater operations, aviation, or medical rescue.
Technical requirements
The standard outlines comprehensive requirements for selecting RPE based on hazard identification. It mandates that employers evaluate the workplace to identify hazardous atmospheres, including oxygen deficiency and airborne contaminants. Employers must calculate the hazard factor (HF) to determine the appropriate level of protection. The standard specifies Assigned Protection Factors (APF) for various types of RPE, such as powered air-purifying respirators (PAPR) and self-contained breathing apparatus (SCBA). It also details the selection criteria based on contaminant types (particulates, gases, vapors) and their hazard levels, referencing GBZ 2.1-2019 for occupational exposure limits. Additionally, it requires the establishment of a Respiratory Protection Program, encompassing training, fit testing, and maintenance procedures.
Testing methods
The standard references several testing methods to ensure proper RPE selection and functionality. It includes fit testing procedures, both qualitative (QLFT) and quantitative (QNFT), to verify the seal between the user's face and the respirator. Methods such as the aerosol quantitative fit test and the controlled negative pressure (CNP) REDON method are detailed. Users must perform a wearer-seal check before each use. The standard also references specific testing for filter elements and air quality for supplied-air respirators, ensuring compliance with GB 31975 for compressed air requirements.
FAQs
What products are regulated under GB 18664-2025?
GB 18664-2025 regulates the selection, use, and maintenance of all types of respiratory protective equipment (RPE), including air-purifying respirators, powered air-purifying respirators (PAPR), supplied-air respirators, and self-contained breathing apparatus (SCBA) used in Chinese workplaces.
Are there any updates from the previous version of GB 18664-2025?
Yes, this version replaces GB/T 18664-2002. Key updates include revised terminology, new requirements for high-temperature and high-humidity environments, updated APF values, and the addition of specific sections on the use of SCBA and criteria for discarding and replacing equipment.
How does GB 18664-2025 differ from international standards like ISO?
While aligning with international practices such as those in ISO 16975, GB 18664-2025 incorporates specific Chinese occupational health standards like GBZ 2.1-2019 for calculating hazard factors and sets mandatory requirements for the Respiratory Protection Program tailored to Chinese regulatory frameworks.
