History of U.S. Respirator Approval

Area of Science:

• Occupational Health and Safety
• Industrial Hygiene
• History of Technology

Background:

• Respirators have a long history of use, evolving significantly over time.
• The need for standardized respiratory protection became apparent due to workplace hazards, especially in mining.
• Prior to formal certification, respirator development and use varied widely.

Purpose of the Study:

• To chronicle the historical development of respirator requirements in the United States.
• To examine the evolution of respirator use, improvements, and certification processes.
• To elucidate the reasons for government intervention in establishing respirator certification standards.

Main Methods:

• Historical review of respirator development and regulation.
• Analysis of primary source documents related to industrial safety and government standards.
• Examination of the influence of specific industries, like mining, on regulatory development.

Main Results:

• The article traces the trajectory of respirators from early designs to the establishment of formal certification.
• It highlights the critical role of the mining industry in advocating for government-backed respirator certification.
• Key factors leading to the origination of the American respirator certification program are identified.

Conclusions:

• Government intervention was essential for standardizing respirator efficacy and safety.
• The American respirator certification program arose from a recognized need for reliable respiratory protection in hazardous environments.
• Understanding this history provides context for current respiratory protection standards and regulations.
