Missouri has a significant automotive assembly sector (Ford Kansas City Assembly, General Motors Wentzville, Stellantis St. Louis Assembly), major defense manufacturing (Boeing Defense Space & Security in St. Louis, Fort Leonard Wood), substantial food processing (Tyson, ConAgra, Anheuser-Busch), and significant lead and zinc mining in the Viburnum Trend (New Viburnum lead belt). Missouri’s workers’ compensation system is administered under Mo. Rev. Stat. §287.010 et seq. Federal OSHA applies to most private employers.

Soundtrace provides Missouri employers with OSHA-compliant automated audiometric testing and noise monitoring — building the per-worker records needed to defend WC claims in Missouri’s DOLIR system.

Missouri Workers’ Compensation System Overview

Missouri’s WC system under Mo. Rev. Stat. §287.010 et seq. is administered by the Department of Labor and Industrial Relations. Claims are adjudicated by Administrative Law Judges. Missouri has a 2-year SOL for occupational disease running from the date of last exposure or the date the claimant knew or should have known of the occupational connection. Hearing loss is compensable as a scheduled permanent partial disability.

Federal OSHA Requirements for Missouri Employers

Missouri does not have a state OSHA plan for private-sector employers. Federal OSHA 29 CFR 1910.95 applies directly to general industry employers. Viburnum Trend mining operations are under MSHA jurisdiction.

How Hearing Loss Claims Work in Missouri

Missouri’s aerospace and automotive sectors generate long-tail hearing loss claims. ALJs evaluate audiometric evidence and noise monitoring documentation. Missouri’s Boeing Defense operations — with workers spending decades in aircraft assembly environments — represent significant long-term WC exposure.

Employer Defense Strategy in Missouri

Complete audiometric records from baseline through separation, supported by noise monitoring documentation, are the Missouri DOLIR defense foundation. For Boeing and automotive employers, baseline audiograms at hire establish pre-existing hearing status before Missouri employment, protecting against claims that attribute prior noise exposure to current operations.


Frequently asked questions

What is Missouri’s statute of limitations for occupational hearing loss?
2 years from the date of last exposure or the date the claimant knew or should have known of the occupational connection. For gradual NIHL, the discovery date may be long after noise exposure ends.
Is Missouri under federal OSHA?
Yes. Missouri does not have a state OSHA plan for private-sector employers. Federal OSHA 29 CFR 1910.95 applies directly to general industry employers in Missouri.
