Industrial Hygiene
Engineering can be utilized most effectively when it is applied in the design
or construction phases of new or modified chemical manufacturing processes. Prevention
and controls of leaks, spills, fugitive emissions and other releases is the
goal. Some chemical and physical agents can still be released during normal or abnormal
operations and during plant turnaround procedures and these require continuous
industrial hygiene surveillance. Industrial hygiene principles must continue to
be applied in all phases of the chemical industry from the beginning of the
design and throughout the life of the unit.
