Louisiana Revised Statutes Tit. 23, § 324. Defenses

A. It may be a defense to a charge of discrimination under this Part that an alleged application of qualification standards, tests, or selection criteria that screen out or tend to screen out or otherwise deny a job or benefit to a person with a disability has been shown to be job-related and consistent with business necessity, and such performance cannot be accomplished by reasonable accommodation, as required under this Part.

B. The term “qualification standards” may include a requirement that an individual shall not pose a direct threat to the health or safety of himself or other individuals in the workplace.
