1. An employee works in a plant with a FAR of 4. If this employee works a 4-hr shift, 200 days per year, what is the expected deaths per person per year?

the expected deaths per person per year is 3.2 × 10⁻⁵

Explanation:

The FAR(fatality rate) is used to get the number of deaths based on 1000 workers working all their lifetime. With the workers expected to work for about 50 years. It is based on 10⁸ working hours.

FAR = (number of deaths × 10⁸) ÷ (total hours worked by all employers during the covered period)

In this problem:

FAR = 4,

total hours worked by all employers during the covered period = (4 hr/day × 200 days/year)

total hours worked by all employers during the covered period = 800 hr/year.

(number of deaths per person per year) × 10⁸ = FAR × total hours worked by all employers during the covered period

(number of deaths per person per year) × 10⁸ = (4 deaths) × (800 hr/year)

number of deaths per person per year = 3200/10⁸ = 3.2 × 10⁻⁵

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
