Section 325.51455. Initial exposure monitoring.

(1) An employer shall identify all employees who may be exposed at or above the action level or at or  above  the  STEL  and  accurately determine the exposure of each employee so identified.

(2)  Unless an employer chooses to measure the exposure of each employee who is potentially exposed to formaldehyde, an employer shall develop a representative sampling strategy and measure sufficient exposures within each job classification for each workshift to correctly characterize, and not underestimate, the exposure of any employee  within   each    exposure group.

(3)   The initial monitoring process shall be repeated each time there is a change in any of the following which may result in new or  additional exposure to formaldehyde:

(a)   ) Production.

(b)   Equipment.

(c)   Process.

(d)  Personnel.

(e)   ) Control measures.

(4)   If an employer receives reports of an  employee  who  has   signs   or symptoms of respiratory or  skin  conditions  that  are  associated   with formaldehyde exposure, the employer shall promptly monitor  and determine the affected employee's exposure.
