With the arrival of the heat and the summer season we discuss the possibility of air conditioners to convey the coronavirus indoorsSIMA suggests all preventable interventions to reduce risks
Here are some tips:- Clean up implants before use- Wash split filters with soap and water before igniting- Clean exposed exterior parts with sanitizers- Have the engines, splits or radiator sanitized by experienced technicians- Useful to maintain humidity between 50% and 70%- Avoid directing the air flow from top to bottom- Open windows for a few minutes a day
According to Directive EN149:2001 - A1:2009 (EN 149-A1)
There is a first classification that indicates when to change them- Nr : non-reusable (disposable for a duration of 8 hours)- R : reusable (depending on the condition of the mask)
The acronym must be reported on the mask as well as the filtering power : FFP1, FFP2, FFP3
The marking can also contain the letter "D": Indicates the dolomite powder test and measure its clogging (required for R-ones)Disposable maskNR devices must undergo numerous tests to prove their strength and effectiveness:climate conditioning assessmentefficiency test (FFP acronym)Reusable maskIn R masks, the tests are also tested for hygiene, efficiency and storage, clogging tests (letter D)
FFP stands for filter face protection, the numbers 1,2,3, increasingly indicate the protection they offer.The FFP1 mask filters about 80% of the particles suspended in the air and are used in working contexts. Even if they have a filtering power the size of 0.6 micrometers, they do not guarantee a correct protection against particles the size of a virus. The mask FFP2 and FFP3 filter respectively about 94% and 99% of the particles in the air. They are admittedly more functional for containing the virus.The masks FFP1, FFP2, FFP3 can have from 4 to 6 layers, equipped with elastic for the ear and a three-dimensional shape that favors the adherence on the face.They can be:- WITH VALVE: from protection to...
Do you want to dry them?
Dry them in dryers at high temperatures.Avoid suggested methods that invite you to put masks in the microwave, oven or boiling pot. In the absence of a dryer you can use an iron. I recommend filters, those are not washable but disposable
Do you want to sterilize them?
Use sterilizing powder or bleach. Fill a tray with 5 l of water at 30 degrees C and add: bleach (150 ml) and sterilizing powder (100 grams). Soak them and soak them for an hour. Now they are ready for washing in the washing machine
First of all, you have to choose a fabric with a filter texture that allows you to breathe.The fabrics deemed suitable for filtration are: cotton, silk and cotton flannel, are to be avoided woven with gauze or linen that would lose this functionality.The masks can be washed with a 60-degree cleanser, by hand or in the washing machine with hot water. The use of sanitizers is not necessary
