This is just one reason why a country can’t stockpile SHN 9 Happy father’s day to the best Cat dad shirt in anticipation of a pandemic. There are also other reasons. Can somebody with expert knowledge regarding the production and shelf life of masks please speak up. Didn’t people want it stock piled, ready to be used in an emergency I’m sure that’s what all the people criticising government efforts were whining about. If so could be date of manufacture and expiry date something else? mind you a 6 yr shelf life is long for this equipment so blimey probably is exp date.
Sterilization expires,rubber degrades SHN 9 Happy father’s day to the best Cat dad shirt, glues age and even plastics in the filter may degrade. Clearly not suitable for surgery. Elastic and glue condition can be easily checked. But determining if the plastics in the actual mask filter have degraded to reduce filtering capacity or release fibers is more difficult. We’ve all experienced old plastic nonwoven shopping bags that disintegrate and plastics that get brittle. Other than sterility, it doesn’t necessarily mean that they’re bad but they were never age tested for that long.
