Answer passage (source: Australia):
page_title: Personal protective equipment (PPE) for the health workforce during COVID-19
section_headers: Accessing PPE
section_content: Primary Health Networks
(PHN) can provide masks and respirators from the National Medical
Stockpile to:

general practitioners (GPs)
Aboriginal Community Controlled Health Organisations (ACCHOs) and Health Services
community pharmacies

PHNs can provide masks to allied health professionals in some circumstances.
Allied health professionals may be eligible if:

the masks are for staff to use
there is no commercial supply available
they are working in higher-risk clinical areas, and with higher risk vulnerable patients

PHNs will also consider whether the allied health professional can adjust how
they practice to reduce risk.
For information about PPE standards, read regulation of PPE and
COVID-19 on the Therapeutic Goods Administration website.
Read more about how we manage the limited supply of
PPE.
Eligibility for surgical masks from PHNs
PHNs will provide surgical masks to GPs and ACCHOs if they have a
demonstrated need. This includes:

there is no local supply available commercially
the people coming to your practice are more likely to have been exposed to COVID-19
your practice has an unusual number of patients who have respiratory symptoms

PHNs will provide surgical masks to community pharmacies if they meet
both of the criteria below:

there is no local supply available commercially
staff have significant contact with people who have fever and respiratory symptoms

Eligibility for respirators from PHNs
PHNs will provide respirators to GPs and ACCHOs who:

need to assess suspected COVID-19 cases
do not have respiratory clinics or emergency departments nearby

These practices must have:

isolation facilities and other appropriate infrastructure
staff who are trained in using PPE
a pandemic plan

You must use respirators with other PPE (gowns, gloves and eye protection).
Requesting masks and respirators from PHNs
When you contact your PHN to make a request, explain how you meet the
eligibility requirements.
For the contact details of your PHN, use the PHN map
locator.
If you’re eligible
Generally, PHNs will provide:

2 boxes of 50 surgical masks to each practice
1 box of 50 surgical masks to each community pharmacy

Depending on stock levels, they may give you more. They will consider the size
of your practice or other demonstrated need.
You can give these surgical masks to:

your staff to use for their protection
patients and customers who may have COVID-19
patients and customers who have a confirmed case of COVID-19

We have supplied PHNs with a small number of respirators. They will conserve
these stocks as far as possible.
You must not sell these masks or respirators as commercial stock.

Reviewer feedback on this answer:
This information is irrelevant to the question. This information is about how health professionals can obtain surgical masks and respirators and does not provide any information protection equipment available to protect someone against covid-19 and how to use them as asked in the question.
This is mainly information for the medical community.  There is information on PPE and resources, but I don't think that this is the answer someone with this question is looking for.

This answer explains what PPE is, but there is not enough information here.
This information does not answer the question. This information explain why PPE is used by health workers. It does not provide any information on what types of protection equipment are available during the Covid-19 and how to use them.

section_headers: Informing patients about PPE
section_content: When communicating with patients, explain:

you do not always need to wear PPE if you are both well
if you wear a mask or other PPE it is for their and your protection

If people in your practice wear PPE, you may want to provide signage near the
entrance advising this is to protect patients and staff.
If you are a health practitioner providing in-home care, let the patient know
in advance that you may wear a mask or other PPE when visiting their home.

Reviewer feedback on this answer:
This answer is more about interacting with patients.  It mentions PPE, but that is not the focus.
This does not answer the question. This information does not provide any information on protection equipment against the Covid-19 and how they are to be used. Instead, this provides information and explanation on how health practitioners should communicate with patients about wearing PPE.
