after millions have already been sold to hospitals
They have been
disapproved to use after just weeks of entering the US.
As they failed to
offer adequate protection against the coronavirus, the American food and drug
administration has called for cancellation of the selling of N95 masks that
have been imported from some manufacturers in china.
An amount of these
respirators failed to demonstrate a minimum particulate filtration efficiency of
95 percent upon testing, the agency said.
The N95 has been
listed by the centre of diseases control and prevention as a critical
protective supply that must be reserved for the use of health care workers as
it filters at least 95 percent of airborne particles.
On Thursday, following
the FDA’s move. A decision has been made last month to ask china to review new
export quality control rules for protective equipment needed, so as it will not
be an obstacle to the timely supplies.
Up to now more than 65
manufacturers have been banned from selling their masks inside the United
States due to their inability to fulfil safety requirements and failing in the
qualification tests, the New York Times reported.
Even though they no
longer had to go through rigorous US testing before sale in the US, testing is
still happening after the protective gear is brought to market.
Right after the shortage
of masks the US suffered from in the last months, health care workers had to
manage their own protective gear and so forced to sanitize and reuse personal
protective equipment or use masks that provide less protection than N95.
In spite of the
failure in April, the FDA didn’t revoke the selling privilege of those 65 companies until Thursday may 7.
