Chemical Exposure Monitoring

Create a safer work environment with Midwest Environmental Consulting Services, Inc. (MEC). Chemical exposure monitoring is conducted to ensure that employee exposures to chemicals are within permissible as established by the Occupational Safety and Health Administration (OSHA).

Chemical hazards and toxic substances can create a wide range of health and physical risks for workers. Chemicals can be in the form of gases, mists or vapors, chemical dust, bulk chemicals, and chemical contamination of surfaces. As a result, employees can be subjected to chemical agents in the workplace through the respiratory system, skin, or the digestive system.


Our goal is to ensure chemical safety within the workplace. We provide comprehensive worksite evaluations for all types of chemical exposure. Through our exposure monitoring process, our team will create a list of all chemicals in use within your workplace and perform a detailed evaluation of exposure mitigation processes.

When combining exposure monitoring with our industry-leading strategies, MEC helps you maintain compliance with local and federal regulatory agencies. Our assessment determines the types of controls required to remove or reduce the hazardous chemicals to acceptable levels.

Ototoxic Chemical Exposure

According to the CDC, over 30 million workers are exposed to ototoxic chemicals which are harmful to the ear and hazardous to hearing. These chemicals can be eaten, travel through the skin, or breathed into the body. Once in the blood, ototoxic chemicals can to go the ear and affect the hearing nerve. These chemicals may damage the nerve, causing hearing loss and balance problems.

Organic chemicals are the most common cause of ototoxic exposure, in addition to metals and gases at high levels. The hearing frequencies affected by chemical exposure is different from noise exposure. Certain chemicals can cause hearing loss on their own. Hearing loss can worsen when exposed to both ototoxic chemicals and loud noises.

Airborne chemical exposure is a complicated process. Indoor air quality monitoring is needed to confirm whether a specific hazardous chemical is present. Air monitoring is necessary to determine the employee exposure level to individual dangerous substances. The MEC team will examine the type of chemical contact, the length of contact, and the chemical concentration.
