page_title: What Maritime Pilots Need to Know about COVID-19
section_headers: As a maritime pilot, how can I protect myself and slow the spread of
COVID-19?
section_content: For maritime pilots, potential sources of exposures include close contact with
a vessel crewmember with COVID-19 and touching your nose, mouth, or eyes after
contacting surfaces or handling items that a person with COVID-19 has touched.

Notify your pilots’ association and stay home if having symptoms.
Follow CDC-recommended steps if you are sick. You should not return to work until the criteria to discontinue home isolation are met, in consultation with healthcare providers.
Follow CDC-recommended precautions and notify your pilots’ association if you are well but have a sick family member at home with COVID-19.
Limit close contact (within 6 feet) with others when possible and consider taking the following steps: 
Use external stairs following a path of minimum exposure to anyone on board to access the vessel bridge when possible.
Do not shake hands with anyone aboard, including during the “master-pilot exchange”.
Remind the vessel master to limit wheelhouse crew to essential personnel (such as crew involved in vessel navigation) while the pilot is on board.
Limit your use to one radar, workstation, etc.
Avoid unnecessary contact with frequently touched bridge surfaces.
Consider carrying hand sanitizer containing at least 60% alcohol for all pilotage assignments and use it to clean hands when soap and water are not available for handwashing.
Following each pilot job, clean and disinfect radios, portable pilot units, life jackets, etc. with an EPA-approved disinfectantexternal icon against the virus that causes COVID-19. If EPA-approved disinfectant is not available, a diluted bleach solution prepared according to the manufacturer’s label for disinfection can be used.


CDC recommends wearing cloth face coverings where other social distancing measures are difficult to maintain, especially in areas of significant community-based transmission. Cloth face coverings may prevent people who don’t know they have the virus from transmitting it to others. These face coverings are not surgical masks or respirators and are not appropriate substitutes for them in workplaces where masks or respirators are recommended or required.
Practice proper hand hygiene. This is an important infection control measure. With appropriate hand hygiene, gloves are not necessary for workers not already required to wear them. Wash your hands regularly with soap and water for at least 20 seconds or use an alcohol-based hand sanitizer containing at least 60% alcohol if soap and water are not available. 
Key times to clean hands include: 
Before and after pilotage assignments
After blowing your nose, coughing, or sneezing
After using the restroom
Before eating and before and after preparing food
Before and after putting on, touching, or removing cloth face coverings or personal protective equipment (PPE) (if applicable).
After touching objects which have been handled by coworkers, such as tools, equipment, or surfaces


Do not touch your eyes, nose, or mouth with unwashed hands.
Use tissues when you cough, sneeze, or touch your face. Throw tissues in the trash and wash your hands.

page_title: FAQs for Wildland Firefighters
section_headers: What steps can be taken by wildland fire personnel to prevent infection and spread of COVID-19? How can a crew, module, or resource “isolate as a unit” to better protect themselves?
section_content: The best way to prevent COVID-19 is to avoid being exposed to SARS-CoV-2, the
virus that causes COVID-19. All firefighters and support personnel should have
a basic understanding of COVID-19, how the disease is thought to
spread,
what the symptoms of
the disease are, and what measures can be taken to prevent or minimize the
transmission of the virus that causes COVID-19.
During the fire season, it will be important that members of each fire crew or
module make an effort to operate and isolate as a unit. Management will need
to develop and implement procedures and protocols to prevent possible
exposures to the virus. When possible, crews should not interchange personnel
or equipment between units and should limit the number of personnel who must
interact with people in the community (e.g. fueling vehicles, picking up
supplies, etc.). This will require planning and using technology to safely
accomplish tasks while maintaining social distancing as much as possible. This
may include implementing procedures that allow fire crews or incident
management personnel to stay remote, isolate from other units, or complete
tasks or missions virtually. If close contact with others in the community is
necessary, it is advised that all personnel wear facemasks or cloth face
coverings for source control.
Wildfire management and personnel should prioritize reducing fatigue and
remaining healthy throughout the fire season. Rest and proper hydration and
nutrition should be prioritized and emphasized every workday.

Reviewer feedback on this answer:
This answer is specifically for firemen who work wild fires, not the average fire fighters who works 1 24-hour shift and goes home for 48- hours and returns to work again.
Though there is little specific advice for firefighters (it mostly says management should develop protocols), it does provide some.

page_title: FAQs for Wildland Firefighters
section_headers: In many situations, fire personnel travel from many different geographic locations and live and work closely in shared living spaces, such as bunkhouses, during the fire season. In these situations, how do you prevent infection and spread of COVID-19 for co-workers or crewmates?
section_content: When personnel arrive to their duty stations, it is recommended that
management provide separate spaces for the personnel to socially
distance themselves from others on their crew for 14 days,
if possible. During this period, personnel should take special precautions to
limit any close interactions with other people (maintaining at least 6-feet
distance) and avoid sharing kitchens, living spaces (bedrooms), bathrooms, or
household items.
If shared living spaces and common areas must be utilized during the initial
14 day period after reporting, all personnel should still practice social
distancing (maintaining at least 6 feet distance from one another), wear
cloth face coverings, and frequently clean and
disinfect shared and high touch surfaces. Personnel should also
consider sleeping in opposite directions (head to toe) and avoid using bunk
beds in shared sleeping quarters. Management should also consider increasing
ventilation rates and/or the percentage of outdoor air that circulates within
the shared living and working areas.
When feasible, management should employ mechanisms to support their employees
and limit employees’ interactions with others during this period. This may
include online ordered and delivered groceries, delivered meals, and virtual
and online training tasks.
After the initial 14-day period is over, fire crews and modules who work
together and do not have regular interactions with other people can isolate as
a unit. During this time, personnel should continue to cover their mouth and
nose with tissue or elbow when they cough or sneeze, perform proper hand
hygiene and frequently clean and
disinfect shared spaces,
vehicles, and equipment with EPA-registered
disinfectantsexternal icon that are appropriate for the surface and
effective against SARS-CoV-2, following label instructions. If a crew operates
as a unit, it is not necessary for crew members to wear face coverings unless
they are not feeling
well or interacting with the public (consistent with CDC
guidelines for households living in close
quarters). If interactions with the general public must occur, all
personnel should practice social distancing, wear cloth face coverings,
perform hand hygiene, and disinfect surfaces, objects, or items that are
shared with the general public.

Housing.

Reviewer feedback on this answer:
This answer doesn't apply to firemen who work 24-hour shifts and then go home but seems to imply firemen who are working on a long term assignment (like a wild fire).
This gives long, detailed advice on many aspects of mitigating risk for firefighting crews.
