HOW TO CLEAN AND SANITIZE IN A 3-COMPARTMENT SINK
Before you clean and sanitize items in a three-compartment sink, make sure that you clean and sanitize each sink and drain board. There are 5 steps for cleaning and sanitizing in a 3-compartment sink.
Use the sink in the following manner:
In the 1st compartment, wash with a clean detergent solution at or above 110˚F or at the temperature specified by the detergent manufacturer.
In the 2nd compartment, rinse with hot clean water.
In the 3rd compartment, sanitize with a sanitizing solution mixed at a concentration specified on the manufacturer’s label or by immersing in hot water at or above 171˚F for 30 seconds. Test the chemical sanitizer concentration by using an appropriate test kit.
Rinse, scrape, or soak all items before washing them.
Answer:
Children (ages 6 - 15) 70 – 100 beats per minute. Adults (age 18 and over) 60 – 100 beats per minute.
Based on the results of the study shown below, the epidemiologist has reason to worry because the incidence rate increased over four times the previous level as shown below:
- number of HIV cases = 440 persons
- new incidence rate = 2.25 per 1000 persons
<h3>What is prevalence and incidence rate?</h3>
Prevalence rate is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time.
- Prevalence rate = number of cases/total population × 100%
Incidence rate is the proportion of new cases of a condition observed within a given period of time.
- Incidence rate = number of new cases/population at risk × 1000
- population at risk = total population - previous cases
The number of people who had HIV in January 2012 is calculated as follows:
- number of HIV cases = prevalence rate × total population
number of HIV cases = 2.2% × 20000
number of HIV cases = 440 persons
Incidence rate between February 2012 and January 2013 is calculated as follows:
Incidence rate = 50/(20000 - 440) × 1000
Incidence rate = 2.25 per 1000 persons.
Based on the new incidence rate, the epidemiologist has reason to worry because the incidence rate has increased over four times the previous level.
