Management has established a Laboratory Ventilation Management Plan (LVMP) to help ensure proper design, selection, operation, use, and maintenance of laboratory ventilation equipment.To do this activity you do not need to actually have a PurpleAir.

Following is a sampling of these practices, numbered as they appear in the new standard: It covers all types of laboratory-related ventilation topics including management, system design, construction, hood airflow requirements, airflow testing and monitoring, special requirements for unique lab hoods (such as gloveboxes, ductless hoods, and perchloric acid hoods), airflow management, supply air systems, exhaust air systems, ductwork, recirculation of exhaust air, commissioning of lab ventilation systems, reporting, training and work practices, maintenance, emergency responses, air cleaning and filtration, and appropriate exhaust air pollution control equipment.Īppendix 4 provides an audit tool to help users determine whether they are in compliance with recommended standard practices. The updated standard has over 150 pages, consists of ten main sections and five helpful appendices, and provides over 450 requirements and good practices for labs to follow. They are developed through cooperative efforts of experts and provide a consensus at the time when the standards are published. ANSI Z9 standards specify performance of ventilation equipment so it can provide safe and healthy workplaces. I was honored to be one of those members.īroadly defined, industrial ventilation is a method of controlling the environment with airflow and is used to minimize employee exposures to hazardous chemicals and biological agents, mainly by removing or reducing air contaminants to safe levels of exposure. The update-the first for this standard since 2012, when AIHA was the ANSI Z9 secretariat-was directed by James Coogan, chair of the Z9.5 subcommittee, and completed by sixteen subcommittee members who are competent in lab ventilation. The recently revised ANSI/ASSP Z9.5 standard on laboratory ventilation is now available from the American National Standards Institute and the American Society of Safety Professionals.
