- (a) **Diagnosis or treatment by health professional—** An [owner](/usc/42/13641.md?p=4) or operator of a [facility](/usc/42/11049.md?p=4) which is subject to the requirements of section [11021](/usc/42/11021.md), [11022](/usc/42/11022.md), or [11023](/usc/42/11023.md) of this title shall provide the specific chemical identity, if known, of a [hazardous chemical](/usc/42/11049.md?p=5), [extremely hazardous substance](/usc/42/11049.md?p=3), or a [toxic chemical](/usc/42/11049.md?p=10) to any health professional who requests such information in writing if the health professional provides a written statement of need under this subsection and a written confidentiality agreement under [subsection (d)](#d). The written statement of need shall be a statement that the health professional has a reasonable basis to suspect that—
  - (1) the information is needed for purposes of diagnosis or [treatment](/usc/42/11851.md?p=11) of an individual,
  - (2) the individual or individuals being diagnosed or treated have been exposed to the chemical concerned, and
  - (3) knowledge of the specific chemical identity of such chemical will assist in diagnosis or [treatment](/usc/42/11851.md?p=11).

  Following such a written request, the [owner](/usc/42/13641.md?p=4) or operator to whom such request is made shall promptly provide the requested information to the health professional. The authority to withhold the specific chemical identity of a chemical under [section 11042 of this title](/usc/42/11042.md) when such information is a trade secret shall not apply to information required to be provided under this subsection, subject to the provisions of [subsection (d)](#d).

- (b) **Medical emergency—** An [owner](/usc/42/13641.md?p=4) or operator of a [facility](/usc/42/11049.md?p=4) which is subject to the requirements of section [11021](/usc/42/11021.md), [11022](/usc/42/11022.md), or [11023](/usc/42/11023.md) of this title shall provide a copy of a [material safety data sheet](/usc/42/11049.md?p=6), an inventory form, or a [toxic chemical](/usc/42/11049.md?p=10) [release](/usc/42/11049.md?p=8) form, including the specific chemical identity, if known, of a [hazardous chemical](/usc/42/11049.md?p=5), [extremely hazardous substance](/usc/42/11049.md?p=3), or a [toxic chemical](/usc/42/11049.md?p=10), to any treating physician or nurse who requests such information if such physician or nurse determines that—
  - (1) a medical emergency exists,
  - (2) the specific chemical identity of the chemical concerned is necessary for or will assist in emergency or first-aid diagnosis or [treatment](/usc/42/11851.md?p=11), and
  - (3) the individual or individuals being diagnosed or treated have been exposed to the chemical concerned.

  Immediately following such a request, the [owner](/usc/42/13641.md?p=4) or operator to whom such request is made shall provide the requested information to the physician or nurse. The authority to withhold the specific chemical identity of a chemical from a [material safety data sheet](/usc/42/11049.md?p=6), an inventory form, or a [toxic chemical](/usc/42/11049.md?p=10) [release](/usc/42/11049.md?p=8) form under [section 11042 of this title](/usc/42/11042.md) when such information is a trade secret shall not apply to information required to be provided to a treating physician or nurse under this subsection. No written confidentiality agreement or statement of need shall be required as a precondition of such disclosure, but the [owner](/usc/42/13641.md?p=4) or operator disclosing such information may require a written confidentiality agreement in accordance with [subsection (d)](#d) and a statement setting forth the items listed in paragraphs [(1)](#b-1) through [(3)](#b-3) as soon as circumstances permit.
