ATDs that aren’t COVID-19
True/False: There are several ATDs that are endemic in California.
TRUE: Endemic ATDs in California include influenza, tuberculosis, measles, whooping cough, chicken pox, and mumps
True/False: Everyone in this class performs at least some work tasks with some potential ATD exposure.
TRUE: The Cal/OSHA STD Standard requires annual training for all employees with potential occupational exposure to ATDs.
Where can you find a copy of the COLB ATD Exposure Control Plan?
LBNet Intranet site
True/False: Some bacteria and viruses can travel through the air and infect people at considerable distances from their source.
TRUE: ATDs like tuberculosis or measles can travel over considerable distances, through ventilation systems, etc.
True/False: N95s and surgical masks provide the same level of protection for the wearer.
FALSE: N95 and other respirators are designed to filter the air and protect the wearer from breathing in particles (including disease pathogens); surgical masks do not provide full respiratory protection
After COVID-19, which ATD causes the most deaths in the U.S. each year: tuberculosis, measles (rubeola), influenza (flu), or whooping cough (pertussis)?
Influenza (estimated 20,000 deaths in 2019-2020)
What measures should you take to protect yourself when working with a client or patient with a suspected or confirmed ATD
Wear a surgical mask, physical distancing, use cough etiquette, wash or sanitize your hands
Who is the person responsible for the COLB ATD Exposure Control Plan?
City Health Officer, Dr. Anissa Davis
Which of the following are NOT considered to be a route of entry for ATDs: nose, eyes, mouth, lungs, skin punctures
Skin punctures are not considered an ATD route of exposure (but they are a route of exposure for blood-borne pathogens)
True/False: Both Ingrid and Kevin will be able to get a tight fit when wearing an N95 respirator.
FALSE: Kevin’s beard will prevent a tight fit (must be clean shaven)
Name at least three common symptoms you are likely to see when people are sick with ATDs.
Coughing and sneezing; fever; sweating; chills; muscle aches; fatigue and weakness
Name a situation in your job when a respirator is required.
Working in a room with a TB patient; during sputum induction procedures; home visits; close contact with community members who may be confirmed or suspected cases; working with lab specimens
Name at least two measures aside from masks and respirators that COLB takes to protect employees from ATD exposure.
Walk-in protocols at clinics; physical distancing and barriers; negative pressure in TB clinic; biosafety cabinets in labs; cleaning and disinfecting; vaccinations
Name at least two body processes that create aerosols that could spread disease.
Coughing; sneezing; talking; singing; vomiting; hemorrhage; diarrhea
Name at least one measure aside from masks and respirators that you can take to reduce your exposure to ATDs.
Increase/improve ventilation indoors; maintain physical distance; avoiding close or crowded spaces; wash hands frequently; cleaning and disinfecting; screen clients for symptoms
What ATD commonly produces a rash that starts at the hairline and spreads downward to the neck, trunk, arms, legs, and feet?
Measles
Name something you should do if you think you’ve been exposed to a serious ATD at work.
Report exposure to supervisor/manager; contact OH clinic; complete and submit the incident investigation form (within 48 hrs of suspected exposure) and notify safety office; complete IVOS (usually supervisors or admin) within 24 hrs of suspected exposure
Name at least three ATDs for which COLB offers vaccinations to employees.
Influenza (annual flu shot); measles, mumps, rubella (MMR); varicella; tetanus, diphtheria, pertussis (Tdap); COVID-19
Name at least one medical or laboratory procedure that creates aerosols that could spread disease.
Sputum induction; intubation; bronchoscopy; drug delivery; respiratory support; vortexing open tubes; blowing; pipetting in the lab
Explain how a negative pressure room helps prevent the spread of ATDs.
Designed as a low-pressure vacuum; air in the room is continually replaced and exhausted out of the building so ATDs don’t build up in the air space or in nearby rooms or hallways
