Episode 61 explains how OSHA’s Hazard Communication Standard (29 CFR 1910.1200) handles trade secrets, especially when manufacturers withhold the exact chemical identity of a substance. Dr. Ayers focuses on what employers must know, what manufacturers must disclose, and how safety leaders can protect workers even when full chemical identities are not provided.
A chemical manufacturer may claim a trade secret when:
Revealing the exact chemical identity would harm their competitive position
The chemical identity is proprietary, confidential, or part of a unique formulation
However — and this is the core message of the episode — trade secret status does NOT allow a manufacturer to hide the hazards.
Even when the chemical identity is withheld, the manufacturer must still provide:
All hazard classifications (carcinogen, mutagen, reproductive toxicant, etc.)
All hazard statements
All exposure controls and PPE requirements
All physical and chemical properties relevant to safety
All toxicological information
In other words, workers must still know how the chemical can hurt them and how to protect themselves.
Dr. Ayers explains how SDSs typically indicate trade secrets:
“Trade secret” listed in Section 3 (Composition/Ingredients)
A generic chemical name (e.g., “proprietary solvent blend”)
Concentration ranges instead of exact percentages
But the SDS must still include every hazard associated with the ingredient.
There are specific situations where the manufacturer must disclose the exact chemical identity:
If a treating physician or nurse needs the identity to provide medical care, the manufacturer must disclose it immediately.
A health professional may request the identity for:
Diagnosis
Treatment
Exposure monitoring
Epidemiological studies
The manufacturer may require a confidentiality agreement, but they cannot refuse the request.
If OSHA asks for the identity during an inspection or investigation, the manufacturer must provide it.
Dr. Ayers clears up several misconceptions:
Myth: “If it’s a trade secret, we don’t need an SDS.” Reality: SDS is still required.
Myth: “Trade secret chemicals are less hazardous.” Reality: Some of the most hazardous chemicals are proprietary blends.
Myth: “We can’t protect workers without the exact chemical name.” Reality: Hazards and controls must still be fully disclosed.
Safety leaders must:
Ensure SDSs for trade secret chemicals are still complete
Train workers on hazards even when identities are withheld
Know how to request chemical identities in emergencies
Maintain confidentiality when receiving trade secret information
Ensure medical providers understand their right to request identities
The episode emphasizes that worker protection never takes a back seat to confidentiality.
