"Masks, Eye Protection, and Face Shields.
Masks in combination with eye protection devices, such as
goggles or glasses with solid side shields, or chin-length face shields,
shall be worn whenever splashes, spray, spatter, or droplets of blood or
other potentially infectious materials may be generated and eye, nose,
or mouth contamination can be reasonably anticipated."

"...respirators are not recommended for protection against bloodborne
disease because there is no evidence that bloodborne pathogens can
be or have been transmitted in the healthcare workplace by the
respiratory route." p.51
"Assuming a 'worst case' of a single virion infectivity and knowing the
capability of minute aerosols to remain suspended in air and
therefore spread widely through the facility, respiratory protection
would be necessary for essentially every person within the facility.
However, if such a situation were true, the Agency would expect
seroconversion rates to be drastically increased among those
exposed; but this does not appear to be the case. "Summary, p.52"
"OSHA is not aware of specific engineering controls and work practices
that are currently available to address control of aerosols." p.51
...the Agency (OSHA) lacks sufficient information in some important areas
which it feels must be obtained before it can require employers to
control exposures to aerosols...CDC and NIOSH...are unaware of
research indicating viability of these viruses (HIV and HBV) in

During Tattoo and Piercing, eye, nose
and mouth contamination would not be "reasonably anticipated" from
splashes, spray, spatter or droplets of blood. Therefore, the use
of masks, eye protection and face shields would not be appropriately
the task of tattooing or piercing.
Masks intended to filter out
airborne particles, like surgical masks, are useful but have
a limited effect, according to public health officials. In
the United States, where the threat of contracting the virus
is low, they are not needed; but in China, health officials
are recommending people wear them.
“Wearing a mask walking around
isn’t going to do any good, but if you’re in a situation
where you’re highly exposed, a mask is helpful,” said
Colleen Kraft, associate chief medical officer for Emory
University Hospital. “You may wear a mask when someone is
going to cough directly on you or [in] a place with a lot of
ill people. In a hospital, we wear a mask with patients who
