In this article we will show the importance of an Air Exhaust System with HEPA Filter in Dental Offices or even in Medical Clinics. Understand why it is extremely harmful to use only Split-type air conditioning and what the RDC 50 standard of 2002 recommends in relation to Air Treatment. Good reading!
The Dental Environment
The dental environment, due to its particularities, allows the air to be a potential route of transmission of microorganisms, through droplets and aerosols, which can directly contaminate the professional, reaching the skin or mucosa, by inhalation or ingestion, or indirectly, when contaminate environmental surfaces. Health problems in dentists and other professionals due to unclean air in offices are frequently reported.
Droplets and aerosols are generated during coughing, sneezing or talking. They can contaminate, in addition to the air, rotating instruments, triple syringes or ultrasonic equipment, widely used in care.
The droplets are considered to be large in size and reach up to one meter in distance. Because they are heavy, they quickly settle on these surfaces. Aerosols, on the other hand, are small particles, which can remain suspended in the air for hours and be dispersed over long distances, and can reach other environments when carried by air currents.
The use of Split-type Air Conditioning in isolation in clinics and offices in general is not recommended, as it does not renew the air.
Imagine a closed environment that receives several patients. The possibilities of contamination combined with an air conditioner for continuous use that accumulates viruses, bacteria and fungi, being exposed to aerosols and vapors created during clinical procedures, determine a totally critical and harmful environment for professionals and the patients themselves who will circulate in this place. .
Dental staff and patients will be exposed to various diseases acquired through direct contact (hands or skin) or indirect contact (environmental surfaces or items used by the patient), due to proximity and prolonged exposure time during the performance of the work.
Procedures to Minimize Risks of Airborne Transmission
According to resolution RDC 50 of 2002, the National Health Surveillance Agency – Anvisa – recommends the use of exhaust fans with HEPA filters to ensure air quality.
The air must go through a filtration process that eliminates about 99,99% of particles down to 0,3 µ through HEPA filters. The air is purified and free of impurities. The use of these equipments provides, in addition to the asepsis of the place, a microclimate with comfort in terms of temperature, humidity, distribution and air purity.
The hoods with the use of HEPA Filter provide:
- air filtration
- Air renewal / Exhaustion
- Retains 99% of microbiological agents
