alpha-Naphthylamine requirements

Yes. Alpha‑Naphthylamine is addressed by OSHA under the specific standard 1910.1004, and that standard is linked to the list of OSHA’s carcinogen regulations in 1910.1003 which covers the group referred to as the 13 carcinogens.

Read the OSHA regulatory text at 29 CFR 1910.1004. This is the official standard page that contains the regulatory language, history, and any cross‑references for alpha‑Naphthylamine.

Any employer covered by OSHA’s general industry standards who has operations that involve alpha‑Naphthylamine must follow the requirements in 1910.1004. In other words, if the chemical is present in your workplace and you fall under 29 CFR part 1910, you should consult and comply with the applicable provisions in 1910.1004.

The standard page for 1910.1004 lists its Federal Register history and amendment dates. The regulation’s entry on the OSHA site shows the original rulemaking and subsequent redesignations and amendments (for example, entries from 1974, 1975, 1976, 1978, 1980, 1984, 1993, and 1996) so you can track changes over time on the official standard page.

Alpha‑Naphthylamine is part of OSHA’s carcinogen regulatory structure and the 1910.1004 entry explicitly refers readers to 1910.1003, which compiles and cross‑references OSHA’s list and requirements for the 13 carcinogens. Consult both 1910.1004 and 1910.1003 to understand how alpha‑Naphthylamine fits into that regulatory grouping.

Check whether alpha‑Naphthylamine is present or used during that task and then read the scope and application in 1910.1004 to determine coverage. If the substance is present in your process or workplace, employers subject to 29 CFR part 1910 should follow the provisions set out in 1910.1004 and any cross‑referenced requirements in 1910.1003.

The alpha‑Naphthylamine standard page itself points to related rules; see 1910.1004 and the referenced 1910.1003 (the 13 carcinogens entry). For broader general industry obligations you can also consult the parent part 1910. Use those pages together to identify all applicable duties.

First, confirm the presence and amount of alpha‑Naphthylamine and then consult the text of 1910.1004 to determine required controls and employer responsibilities. As a general step, follow the procedures and obligations in 1910.1004 and other applicable parts of 29 CFR part 1910 to address hazard identification, worker protection, and any required recordkeeping or notifications.

When documenting compliance, reference the official citation 29 CFR 1910.1004 and note any related guidance in 1910.1003. Use the exact regulation citation and, where appropriate, include amendment dates or Federal Register entries shown on the standard page to support your compliance record.

Yes—use 1910.1004 together with relevant parts of 29 CFR part 1910 and the cross‑reference 1910.1003 to identify all applicable requirements. The alpha‑Naphthylamine page directs you to the broader regulatory framework so you can determine where engineering controls, medical surveillance, or other measures may be required.

Yes. The 1910.1004 standard page lists Federal Register entries and amendment dates (for example, 39 FR 23502, 40 FR 23072, and several later entries through 1996). Use those citations shown on the standard page to locate the official rulemaking history and background materials.

The standard is part of OSHA’s general industry regulations in 29 CFR part 1910, so its requirements apply to covered general industry workplaces where alpha‑Naphthylamine is used or present. Consult 1910.1004 to determine specific application and any industry‑specific language or exemptions.

OSHA points users to the broader carcinogen framework by saying "See 1910.1003, 13 carcinogens" on the 1910.1004 page. That cross‑reference shows alpha‑Naphthylamine is part of the set of carcinogen standards that OSHA groups for regulatory purposes—so review both 1910.1004 and 1910.1003 when building your compliance program.

Yes. OSHA letters of interpretation provide agency guidance about how standards are applied in specific situations; consult the alpha‑Naphthylamine standard at 1910.1004 and search OSHA’s Letters of Interpretation for any entries related to carcinogens or the 13‑carcinogen group at 1910.1003. If a letter directly addresses alpha‑Naphthylamine it will help clarify practical obligations, but the regulatory text remains authoritative.

The direct way is to obtain the manufacturer’s chemical composition, Safety Data Sheet, or certificates of analysis and then compare the information to the definitions and scope in 1910.1004. If the material lists alpha‑Naphthylamine or impurities that meet the standard’s coverage, treat the material as covered and follow the requirements in 1910.1004 and related parts of 29 CFR 1910.

Record the hazard assessment showing how you identified chemicals present (e.g., supplier SDSs, product labels, testing results), and cite the standard 1910.1004 as the regulatory basis for any controls or actions taken. Keep those records with your safety program files so you can demonstrate you evaluated alpha‑Naphthylamine in accordance with the requirements of 29 CFR part 1910.

Start with the official OSHA standard page 1910.1004 and the related 1910.1003. If you still need clarification, contact OSHA’s Directorate of Enforcement Programs or your regional OSHA office for interpretation assistance; OSHA’s letters of interpretation (available on the OSHA website) often clarify how regulations apply in real situations.

Possibly — States that operate OSHA‑approved State Plans must have standards and enforcement at least as effective as Federal OSHA, but they may be more stringent. Always check the federal standard 1910.1004 and then confirm whether your State Plan has additional or different requirements.
