Watson v. Olin Corp, 5:16-cv-00235

Plaintiff Laura Watson alleges chemical exposure while employed by Olin Mathieson Chemical Corp. at its Lake Charles plant from 1948–1950 as an office worker/typist.
She claims exposure to ammonia, sodium hydroxide (and possibly other chemicals) caused chemical burns in her lungs, difficulty breathing, and substantially decreased lung capacity decades later, requiring oxygen and confinement.
Plaintiff filed a tort claim for failure to provide a safe workplace; Olin (successor to Olin Mathieson) moved to dismiss under Fed. R. Civ. P. 12(b)(6) and, alternatively, for a more definite statement under Rule 12(e).
After an amended complaint clarified employment dates (withdrawn 1952–1955 allegation), the court treated the motion as directed at the second amended complaint.
Central legal question: whether the pre-1952 Louisiana Workers’ Compensation Act (LWCA) covers Plaintiff’s asserted long-latency injuries (barring tort recovery) or whether those injuries fall outside the LWCA akin to asbestos/mesothelioma.
Court denied dismissal (12(b)(6)) because the factual/medical question whether the alleged exposures can cause long-latency injury cannot be resolved at the pleading stage; granted Rule 12(e) in part, ordering Plaintiff to specify her alleged injuries (but not to identify all chemicals).

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether LWCA (pre-1952) bars tort claim	Watson: injuries are long-latency occupational disease (like mesothelioma) and thus outside original LWCA	Olin: exposures were acute poisonous-fume "accidents" under pre-1952 LWCA so LWCA is exclusive remedy	Court: factual question; must accept plaintiff's allegations; 12(b)(6) denied because determination requires medical evidence
Whether exposure to ammonia/lye can cause decades-later injuries	Watson: may be possible; analogy to asbestos latency	Olin: such chemicals cause only immediate injury; no scientific support for decades-later lung "chemical burns"	Court: not resolved at pleading stage; expert/medical record needed; pleadings plausible
Applicability of Arrant (noise-induced hearing loss) precedent	Watson: distinguishes long-latency diseases from traumatic injuries	Olin: Arrant supports treating delayed-onset injury as an "accident" under LWCA	Court: Arrant turned on expert evidence of immediate inner-ear injury; analogous factual determination not appropriate on pleadings here
Whether Rule 12(e) more definite statement required	Watson: cannot identify all historical chemicals; added hydrogen sulfide in opposition	Olin: requests specific list of chemicals and precise injuries	Court: denied as to chemicals (defendant better positioned to identify them); granted as to injuries — plaintiff must specify physical injuries and onset dates within 14 days
