21. III. Social/Physical Distancing
Social distancing, also called “physical distancing,” means keeping a safe
space between yourself and other people who are not from your
household.
To practice social or physical distancing, stay at least 6 feet (about 2 arms
length) from other people who are not from your household in both indoor and
outdoor spaces.
Social or physical distancing should be practiced in combination with other
everyday preventive actions to reduce the spread of COVID-19.
https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/social-distancing.html

23. Tips for Social/Physical Distancing
● Know Before You Go: Before going out, know and follow the guidance from local
public health authorities where you live.
● Prepare for Transportation: Consider social distancing options to travel safely when
running errands or commuting to and from work
● Limit Contact When Running Errands: Only visit stores selling essentials when you
absolutely need to, and stay at least 6 feet away from others who are not from your
household while shopping and in lines. If possible, use drive-thru, curbside pick-up, or
delivery services to limit face-to-face contact with others.

24. Continued...
● Choose Safe Social Activities: Stay connected by calling, using video chat, and social media. If
meeting others in person (e.g., at small outdoor gatherings, yard or driveway gathering with a
small group of friends or family members), stay at least 6 feet from others not in household.
● Keep Distance at Events and Gatherings: Try to avoid crowded places where it may be difficult
to stay at least 6 feet away from others. Pay attention to any physical guides, such as tape
markings on floors or signs on walls, directing attendees to physically distance. Allow other people
6 feet of space when you pass by them in both indoor and outdoor settings.
● Stay Distanced While Being Active: Consider going for a walk, bike ride, or wheelchair roll in
your neighborhood or in another safe location where you can maintain at least 6 feet of distance.
If you decide to visit a nearby park, trail, or recreational facility, consider how many other people
might be there and choose a location where it will be possible to stay physically distanced.

25. IV. PPE Identification & Use
● PPE stands for personal protective equipment and is specialized clothing
or equipment worn by an employee for protection against infectious
materials
● Types of PPE:
○ Gloves -- protect hands
○ Gowns -- protect skin/clothing
○ Masks -- protect nose/mouth
○ Goggles -- protect eyes
○ Face shields -- protect face, mouth, nose, and eyes

26. How to Put On (Don) PPE
1. Identify and gather the proper PPE to don.
2. Perform hand hygiene using hand sanitizer.
3. Put on isolation gown. Tie all of the ties on the gown.
4. Put on facemask.
○ Should be extended under your chin and both your mouth and nose should be
protected. Ties should be secured on crown of head (top tie) and base of neck (bottom
tie). If mask has loops, hook them appropriately around your ears.
5. Put on face shield or goggles.
○ Face shields provide full face coverage. Goggles also provide excellent protection for
eyes, but fogging is common.
6. Put on gloves. Gloves should cover the cuff (wrist) of gown.

27. How to Take Off (Doff) PPE
1. Remove gloves. Ensure glove removal does not cause additional contamination of hands.
2. Remove gown. Untie all ties (or unsnap all buttons). Some gown ties can be broken rather
than untied. Do so in gentle manner, avoiding a forceful movement. Reach up to the
shoulders and carefully pull gown down and away from the body. Rolling the gown down is an
acceptable approach. Dispose in trash receptacle. *
