section_content: Know how it spreads

There is currently no vaccine to prevent coronavirus disease 2019 (COVID-19).
The best way to prevent illness is to avoid being exposed to this virus.
The virus is thought to spread mainly from person-to-person. 
Between people who are in close contact with one another (within about 6 feet).
Through respiratory droplets produced when an infected person coughs, sneezes or talks.
These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
Some recent studies have suggested that COVID-19 may be spread by people who are not showing symptoms.



Wash your hands often

Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.
If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
Avoid touching your eyes, nose, and mouth with unwashed hands.

Avoid close contact

Avoid close contact with people who are sick, even inside your home. If possible, maintain 6 feet between the person who is sick and other household members.
Put distance between yourself and other people outside of your home. 
Remember that some people without symptoms may be able to spread virus.
Stay at least 6 feet (about 2 arms’ length) from other people.
Do not gather in groups.
Stay out of crowded places and avoid mass gatherings.
Keeping distance from others is especially important for people who are at higher risk of getting very sick.



Cover your mouth and nose with a cloth face cover when around others

You could spread COVID-19 to others even if you do not feel sick.
Everyone should wear a cloth face cover when they have to go out in public, for example to the grocery store or to pick up other necessities. 
Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.


The cloth face cover is meant to protect other people in case you are infected.
Do NOT use a facemask meant for a healthcare worker.
Continue to keep about 6 feet between yourself and others. The cloth face cover is not a substitute for social distancing.

Cover coughs and sneezes

If you are in a private setting and do not have on your cloth face covering, remember to always cover your mouth and nose with a tissue when you cough or sneeze or use the inside of your elbow.
Throw used tissues in the trash.
Immediately wash your hands with soap and water for at least 20 seconds. If soap and water are not readily available, clean your hands with a hand sanitizer that contains at least 60% alcohol.

Reviewer feedback on this answer:
This is the closest "best" answer. It would be 100% perfect if it said "first responders" or specifically mentioned LEO (law enforcement officers), paramedics, or firemen.
This talks about COVID in general, how it spreads and precautions to take. But the question wants to know about first responders and this makes no mention of the unique situations that those people have to deal with

page_title: FAQs for Law Enforcement Agencies and Personnel
section_headers: Should law enforcement personnel and other first responders take additional precautions when coming home, even if they have no symptoms of COVID-19, to avoid potentially exposing household members?
section_content: CDC recommends that law enforcement personnel practice everyday
measures to
protect their household members from becoming ill. These measures include:

hand hygiene
covering coughs and sneezes
disinfecting frequently touched surfaces daily

Many law enforcement personnel routinely change out of their uniforms at the
station and wear street clothes and shoes home. Laundry services for uniforms
may be provided by law enforcement agencies. Continuing this practice may help
minimize the potential of transmitting the virus that causes COVID-19 and
other potential take-home exposures. Law enforcement personnel should perform
hand hygiene after changing out of
uniforms.
They also should have a plan for household members who are at higher risk for
severe illness from COVID-19.

Reviewer feedback on this answer:
Question is asking about first responders but this is only about police officers. Even the list that's here feels very incomplete and should go into a lot more detail than that
This is good advice for keeping safe while at work. It would be a better answer if combined with answer #2 as well.

section_headers: What precautions should wildland firefighting personnel take when they come off assignment and return back home to their families?
section_content: When crew members return home after an assignment, they should continue to
self-monitor for fever and symptoms. Personnel who feel sick should follow CDC
guidance for What to Do If You Are Sick. Personnel who have vulnerable family
members within their home should consider social distancing from those
family members or wearing a facemask or cloth face covering if social
distancing is not possible, even if they feel well and do not have symptoms,
for 14 days.

Reviewer feedback on this answer:
This doesn't seem very relevant at all to what's being asked. This is just a generic thing that personnel at any company should follow. Nothing related to first responders
This is good advice on how responders can keep family members safe but doesn't address how workers can be safe while at work.
