Silica Deaths by Occupation and Industry
The first column is the occupational or industrial classification. The second column (PMR) is the observed number of deaths from silicosis per occupation divided by the expected number of deaths.   Therefore, a value of one indicates no additional risk.  A value of ten would indicate a risk ten times greater than normal risk of silicosis.
