6.1 Face coverings

PPE protects the user against health or safety risks at work. It can include
items such as safety helmets, gloves, eye protection, high-visibility
clothing, safety footwear and safety harnesses. It also includes respiratory
protective equipment, such as face masks.
Where you are already using PPE in your work activity to protect against non-
COVID-19 risks, you should continue to do so.
At the start of this document we described the steps you need to take to
manage COVID-19 risk in the workplace. This includes working from home and
staying 2m away from each other in the workplace if at all possible.When
managing the risk of COVID-19, additional PPE beyond what you usually wear is
not beneficial. This is because COVID-19 is a different type of risk to the
risks you normally face in a workplace, and needs to be managed through social
distancing, hygiene and fixed teams or partnering, not through the use of PPE.
The exception is clinical settings, like a hospital, or a small handful of
other roles for which Public Health England advises use of PPE, for example,
first responders and immigration enforcement officers. If you are in one of
these groups you should refer to the advice at:

COVID-19: personal protective equipment (PPE) plan
COVID-19: cleaning in non-healthcare settings

Workplaces should not encourage the precautionary use of extra PPE to protect
against COVID-19 outside clinical settings or when responding to a suspected
or confirmed case of COVID-19.
Unless you are in a situation where the risk of COVID-19 transmission is very
high, your risk assessment should reflect the fact that the role of PPE in
providing additional protection is extremely limited. However, if your risk
assessment does show that PPE is required, then you must provide this PPE free
of charge to workers who need it. Any PPE provided must fit properly.

Reviewer feedback on this answer:
This discusses the use of PPE in a workplace clinical setting, and does not address visiting other's homes.
This is talking about PPE in the work environment. The question is asking about when visiting the home of a person.

page_title: Guidance Staying safe outside your home
section_headers: Face coverings
section_content: If you can, wear a face covering in enclosed public spaces where social
distancing isn’t possible and where you will come into contact with people you
do not normally meet. This is most relevant for short periods indoors in
crowded areas, for example, on public transport or in some shops. You should
be prepared to remove your face covering if asked to do so by police officers
and staff for the purposes of identification.
Evidence suggests that wearing a face covering does not protect you. However,
if you are infected but have not yet developed symptoms, it may provide some
protection for others you come into close contact with.
Face coverings do not replace social distancing. If you have symptoms of
COVID-19 (cough, and/or high temperature, and/or loss of, or change in, your
normal sense of smell or taste - anosmia), you and your household must isolate
at home: wearing a face covering does not change this.
A face covering is not the same as the surgical masks or respirators used by
healthcare and other workers as part of personal protective equipment. These
should continue to be reserved for those who need them to protect against
risks in their workplace, such as health and care workers, and those in
industrial settings, like those exposed to dust hazards.
Face coverings should not be used by children under the age of 2 or those who
may find it difficult to manage them correctly. For example, primary age
children unassisted, or those with respiratory conditions.
It is important to use face coverings properly and wash your hands before
putting them on and taking them off.
You can make face-coverings at
home. The key thing is it should cover the mouth and nose.

Reviewer feedback on this answer:
This gives good information about when and where to wear a face mask effectively, but does not address going to other people's homes.
This is talking about PPE in public spaces. The question asks about a private space such as inside the home of a person.
