Sanitizing n95 masks
Tags: None -
I feel bad for people at my wife’s work, they get 1 n95 a shift and they have to put them in a plastic bio bag (same bags lab samples are put in) in between using them... I’m like hold the f@$: up you put the contaminated side in the bag and seal it with the uncontaminated side..... now you’ve just contaminated both sides one of which gets placed on your face and over your nose .... geniusesNRA Life Of Duty Member -
Yes, sanitized 20 times with a machine approved by the FDA.Comment

For those of you that have an UVGI lamp...
Effects of Ultraviolet Germicidal Irradiation (UVGI) on N95 Respirator Filtration Performance and Structural Integrity. Source: NIH
Abstract
The ability to disinfect and reuse disposable N95 filtering facepiece respirators (FFRs) may be needed during a pandemic of an infectious respiratory disease such as influenza. Ultraviolet germicidal irradiation (UVGI) is one possible method for respirator disinfection. However, UV radiation degrades polymers, which presents the possibility that UVGI exposure could degrade the ability of a disposable respirator to protect the worker. To study this, we exposed both sides of material coupons and respirator straps from four models of N95 FFRs to UVGI doses from 120-950 J/cm(2). We then tested the particle penetration, flow resistance, and bursting strengths of the individual respirator coupon layers, and the breaking strength of the respirator straps. We found that UVGI exposure led to a small increase in particle penetration (up to 1.25%) and had little effect on the flow resistance. UVGI exposure had a more pronounced effect on the strengths of the respirator materials. At the higher UVGI doses, the strength of the layers of respirator material was substantially reduced (in some cases, by >90%). The changes in the strengths of the respirator materials varied considerably among the different models of respirators. UVGI had less of an effect on the respirator straps; a dose of 2360 J/cm(2) reduced the breaking strength of the straps by 20-51%. Our results suggest that UVGI could be used to effectively disinfect disposable respirators for reuse, but the maximum number of disinfection cycles will be limited by the respirator model and the UVGI dose required to inactivate the pathogen.

I have 2 UV lights. One for sterilizing fish tank water and the other for generating ozone gas.
Chances of effing yourself up with those lamps if removed from their appliances.. about 100%
Chances of catching and dying from WuhanVirus about 0.1%Comment
