MO HB170

Adds "occupational disease" to the list of conditions for which employers must provide workers' compensation benefits, alongside accidental injury or death.

Removes the word "accidental" from the statute to clarify that employees' rights and remedies exclude other legal remedies for injury or death by accident or occupational disease, except where not provided by the workers' compensation chapter.

Maintains existing provisions allowing compensation reduction of 25-50% if employees fail to use safety devices or follow employer safety rules with actual knowledge of those rules.

Preserves existing provisions for 50% compensation reduction or forfeiture of benefits if injury is sustained in conjunction with alcohol or nonprescribed controlled drug use in violation of employer policy.

Preserves existing provisions excluding compensation for injuries arising from recreational activities, mental injuries from work stress or disciplinary actions, and intentional self-inflicted injuries, with specified exceptions.
