Why Hire A Certified Industrial Hygienist?

Once OSHA determines that a violation has occurred involving an employee being over exposed to noise or air contaminants,  OSHA then requires that the employer verify that the exposure has been controlled.   This happens by hiring a Certified Industrial Hygienist to conduct testing and provide a written report that documents the current exposure levels for employees.

OSHA requires this because:

  1. The certification and contiuing education requirements ensures the highest quality,          accuracy, and efficiency sampling and documentation available.
  2. Certification guarantees that you are hiring someone committed to practice ethically. 

Many businesses have found it more efficient and economical to work with a Certified Industrial Hygienist for the quality of their work and the knowledge required to assess employee exposure to chemical mixtures found in most products.
