If any suspicious information is obtained in the routine interview,
the physician should obtain a more detailed history. Information on
duration and intensity of exposure is important. It is important to
learn how the patient worked with the suspected toxin and to
consider how he or she may have absorbed the material.
Information is needed on any respirators or protective clothing the
patient may have worn.
