section_headers: As a waste collector or recycler, how can I protect myself and slow the
spread?
section_content: For waste collectors and recyclers, potential sources of exposure include
having close contact with a coworker or member of the public with COVID-19, or
by contacting surfaces touched or handled by a person with COVID-19.

Notify your supervisor 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 and state and local health departments.
Follow CDC recommended precautions and notify your supervisor if you are well but have a sick family member at home with COVID-19.
Limit close contact with others by maintaining a distance of at least 6 feet when possible.
CDC recommends wearing cloth face coverings in public settings 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 routine cleaning and disinfection of frequently touched surfaces, such as steering wheels, door handles, levers, and control panels. Key times for cleaning include: 
At the beginning and end of every shift
After anyone else uses your vehicle or workstation


Wear your normal personal protective equipment (PPE) as you go about your day. This may include work gloves, eye protection (such as safety glasses), and a work uniform or coveralls.
Use Environmental Protection Agency (EPA) registered disinfectantexternal icon to clean eye protection at the beginning and end of your shift.

Replace work gloves when they become damaged (for example, if they are ripped or torn). 

Practice proper hand hygiene and cough and sneeze etiquette. These are important infection control measures. 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. Key times to clean hands include:


Before and after work shifts and work breaks


After blowing your nose, coughing, or sneezing
After using the restroom
Before eating or preparing food
Before putting on, touching, or removing cloth face coverings



Avoid contact with body fluids, if possible. Use gloves if you have to touch surfaces contaminated by body fluids.

Avoid touching your eyes, nose, or mouth. Be extra careful when putting on or taking off PPE.
Stay up to date on your company’s current policies on COVID-19. Follow the social distancing guidance provided by your employer.

page_title: Frequently Asked Questions
section_headers: COVID-19 and Water
Should wastewater workers take extra precautions to protect themselves from the virus that causes COVID-19?
section_content: Recently, the virus that causes COVID-19 has been found in untreated
wastewater. While data are limited, there is no information to date that
anyone has become sick with COVID-19 because of exposure to wastewater.
Standard practices associated with wastewater treatment plant operations
should be sufficient to protect wastewater workers from the virus that causes
COVID-19. These standard practices can include engineering and administrative
controls, hygiene precautions, specific safe work practices, and personal
protective equipment
(PPE)
normally required when handling untreated wastewater. No additional
COVID-19–specific protections are recommended for workers involved in
wastewater management, including those at wastewater treatment facilities.

page_title: Clinical Questions about COVID-19: Questions and Answers
section_headers: Waste Management
What do waste management companies need to know about wastewater and sewage coming from a healthcare facility or community setting with either a known COVID-19 patient or person under investigation (PUI)?
section_content: Waste generated in the care of PUIs or patients with confirmed COVID-19 does
not present additional considerations for wastewater disinfection in the
United States. Coronaviruses are susceptible to the same disinfection
conditions in community and healthcare settings as other viruses, so current
disinfection conditions in wastewater treatment facilities are expected to be
sufficient. This includes conditions for practices such as oxidation with
hypochlorite (i.e., chlorine bleach) and peracetic acid, as well as
inactivation using UV irradiation.

Reviewer feedback on this answer:
The answer realizes the question without actually addressing the primary query. It is a good result, but requires logical inferring by whomever reads the answer and has the question.
The response is supposed to address the precautions needed to be taken by those exposed to waste water
