Aerosol Transmissible Diseases

ORIGIN: Moldex Technical Services Department


In 2009 the State of California passed a regulation addressing Aerosol Transmissible Diseases. This is Codified in Subchapter 7. General Industry Safety Orders Group 16. Control of Hazardous Substances Article 109. Hazardous Substances and Processes section 5199.

An aerosol transmissible disease (ATD) or Aerosol Transmissible Pathogen (ATP) is a disease or pathogen for which droplet or airborne precautions are required.

This regulation effectively addresses the standard operating procedures required to protect workers in numerous types of healthcare facilities, emergency responders and others. This regulation provides comprehensive guidance to those workers and their employers. It addresses those that may provide medical services to persons reasonably anticipated to be cases or suspected cases of an aerosol transmissible disease. Also covered are facilities, services or operations that perform aerosol-generating procedures such as pathology laboratories, medical examiners, coroner and mortuaries, and also laboratories that perform procedures with materials that contain or are reasonably anticipated to contain aerosol transmissible pathogens or zoonotic aerosol transmissible pathogens.

Specifically, with regard to respiratory protection, N95 filtering facepiece respirators must be provided unless the employer’s evaluation determines that a more protective respirator is necessary. Effective September 1, 2010 and amended in 2013, the employer must provide a powered air purifying respirator or (PAPR) with High Efficiency Particulate Air filters, or respirators providing equivalent protection or greater, to employees who perform high hazard procedures on Airborne Infectious Disease (AIrID) cases or suspected cases and employees who perform high hazard procedures on cadavers potentially infected with Aerosol Transmissible Diseases . The one exception to this is that Paramedics and other emergency medical personnel in field operations may use a N,R or P100 in lieu of a PAPR, but the employer must make an assessment for the presence of oil if a N100 is used.
