Risk Assessment Framework

Risks	Definitions		Example 1-Lung Ultrasound Obtainment	Example 2-Personal Exposure Assessment
Participant	Participant group (i.e. pregnant woman/new mother, child, older adult woman)		Child	Older Adult Woman, Pregnant Woman
Location	Place where sample is collected or procedure performed		Healthcare facility	Home (indoor or outdoor)
Proximity to the participant	Close: The procedure requires the field worker and participant to be closer than 2 meters (6 feet) of one another.[11] If a procedure produces aerosolization, then it is automatically considered close contact.		Close	Close
	Socially distant: The procedure to be performed allows the field worker and participant to maintain a distance of > 2 meters (6 feet) apart from one another.
Exposure time	Short : The procedure can be performed without the staff and participant to be in close proximity for > 15 minutes.[11]		Prolonged	Setup: short to prolonged
	Prolonged: The procedure requies the field worker and participant to be in close proximity for > 15 minutes.			Take-down: short
Aerosolization Potential	None: The procedure is unlikely to produce any aerosolized particles.		Yes	None
	Yes: The procedure may produce aerosolized particles.[11]
Personal Protective Equipment (PPE) Needs	Criteria to determine PPE	PPE Needs	N95 or equivalent respirator + eye protection + gown + gloves	Paper facemask + eye protection + gloves
	Participant and staff are not in close contact at anytime. No aerosolizing procedures. No processing of biologic samples.	Paper or cloth facemask [9]
	Participant and staff may be in close contact but only for a short period of time. Biologic materials may be processed in the lab. No aerosolizing procedures performed.	Paper facemask (preferably procedural quality) + eye protection + gloves (if the procedure requires touching the participant and/or a clinical specimen is collected)[9]
	Participant and staff may be in close contact for a prolonged period of time and/or an aerosolizing procedure is occuring	N95 or equivalent respirator + eye protection + gown + gloves [9]
	Participant and staff may be in close contact for a prolonged period of time and/or an aerosolizing procedure is occuring in a manner that staff and participants can not be safely protected.	Procedure will not be performed
