By keeping your equipment properly maintained, you ensure the safety of users, the workplace and the environment. You'll also extend equipment longevity, prevent high costs and reduce unnecessary downtime.
Proper Cleaning
BSCs and Ductless Fume Hoods should be wiped down before and after each use with a disinfectant. The EPA suggests a more thorough cleaning once a quarter. Use a disinfectant with 70% alcohol or similar non-corrosive agent.
Replacing HEPA Filters
HEPA filters should be checked every month and typically replaced every six months. Prior to removal, the filter must be decontaminated through formaldehyde gas. The life of a filter can range from 2 months to two years depending on chemicals used.
Ultraviolet Light & Blower Motor Checks
UV lights should be wiped down with alcohol to prevent decreased effectiveness. Blower motors should be turned on several minutes before use per manufacturer recommendations.
Testing And Certification
BSCs and Ductless Fume Hoods must be tested and certified by an accredited field certifier at install, when moved, after major repair, or at least once a year. Tests include HEPA filter leak, down-flow blower speed and UV light intensity.
