COVID-19 Interim <br /> Health & Safety Guidance <br /> Occupational Risk Pyramid <br /> for COVID-19 <br /> Medium \� <br /> Very High Exposure Risk(Activities not conducted by Roux) <br /> Very high exposure risk includes occupations/work activities with high potential for exposure to known or suspected <br /> sources of COVID-19 during specific medical, postmortem, or laboratory procedures. This can include but is not <br /> limited to: <br /> • Healthcare workers (e.g., doctors, nurses, dentists, paramedics, emergency medical technicians) performing <br /> aerosol-generating procedures (e.g., intubation, cough induction procedures, bronchoscopies, some dental <br /> procedures and exams, or invasive specimen collection)on known or suspected COVID-19 patients. <br /> • Healthcare or laboratory personnel collecting or handling specimens from known or suspected COVID-19 <br /> patients (e.g., manipulating cultures from known or suspected COVID-19 patients). <br /> High Exposure Risk(Activities not conducted by Roux) <br /> High exposure risk occupations/work activities include exposure to known or suspected COVID-19 positive <br /> individuals. This can include but not limited to: <br /> • Healthcare delivery and support staff(hospital staff who must enter patients' rooms) exposed to known or <br /> suspected COVID-19 patients. <br /> • Medical transport workers (ambulance vehicle operators) moving known or suspected COVID-19 patients <br /> in enclosed vehicles. <br /> • Mortuary workers involved in preparing bodies for burial or cremation of people known to have,or suspected <br /> of having, COVID-19 at the time of death. <br /> • Those who have frequent or sustained contact with coworkers, including under close working conditions <br /> indoors or in poorly ventilated spaces in various types of industrial, manufacturing, agriculture,construction, <br /> and other critical infrastructure workplaces. <br /> • Those who have frequent indoor or poorly ventilated contact with the general public, including workers in <br /> retail stores, grocery stores or supermarkets, pharmacies, transit and transportation operations, law <br /> enforcement and emergency response operations, restaurants, and bars. <br /> Medium Exposure Risk <br /> Medium exposure risk occupations/work activities include those that require frequent and/or close contact with <br /> (i.e., within 6 feet for a cumulative total of 15 minutes or more over a 24-hour period)) people who may be infected <br /> with COVID-19, but who are not known or suspected to be COVID-19 positive. For most of our worksites, it is <br /> assumed there is on-going community transmission for COVID-19. Therefore, workers who work at sites and may <br /> have contact with the general public, other contractors, high-population-density work environments (i.e., greater <br /> than 10 people) fall within medium exposure risk group category. This can include, but is not limited to, sampling <br /> events that require two or more workers to collect and log samples in close contact or work occurring in an interior <br /> space with limited ventilation and several workers present. <br /> 01/2022 COVID-19 Interim Health and Safety Guidance I ROUX 13 <br />
