Many may be infectious (even without fever or symptoms)
Works 10 hrs per day

2

*May require input from a health and safety professional.

Control Band C
Requires Multiple Source and Path and Likely Receptor Controls

3

Source Controls

Screen and exclude all patients who are symptomatic

Effect of Source Controls

Interactions with people who are mostly healthy (lowers likelihood of exposure)

Path Controls

Might not be possible

Receptor Controls

Ophthalmologist would need to wear a respirator to protect from exposure.

Use Receptor Controls (e.g., PPE) only if all other controls have been implemented and are not effective
