New York Requires Certain Employers to Maintain Opioid Antagonists; Amendment Clarifies Scope and Timeline

Seyfarth Synopsis: New York law now requires employers that are federally required to maintain first‑aid supplies to have an opioid antagonist available at the workplace. Amendments signed in February 2026 clarify certain aspects of the law, which takes effect on December 13, 2026.

In December 2025, New York enacted a new requirement mandating that certain employers maintain an opioid antagonist at the workplace.  In February 2026, the Legislature passed—and the Governor signed—a chapter amendment refining coverage, definitions, and implementation timing.  This follows California’s similar recent legislation imposing similar requirements (see a comprehensive recent article from our Workplace Safety team here).  As with other recent worker‑safety measures, these developments impose new compliance obligations on private‑sector employers operating in New York. 

Summary of the New Requirements

Here is a breakdown of the requirements under the amended law:

• Which Employers Are Covered? Only employers that are federally required to maintain first aid supplies under OSHA standards fall within the mandate. This generally includes employers that must maintain “adequate first aid supplies” because no infirmary or clinic is sufficiently near the workplace. Moreover, an employer is defined as any person, corporation, LLC, or association employing individuals in any occupation, trade, or business, but excludes governmental entities.
• What Must Employers Provide? Covered employers must maintain an opioid antagonist in the workplace among the federally required first aid supplies. The amendment clarifies that an antagonist must be available somewhere in the workplace—not necessarily in each individual first aid kit.
• What Counts as an “Opioid Antagonist”? The law incorporates the definition in Public Health Law § 3309, meaning a drug approved by the FDA that negates or neutralizes the effects of an opioid in the body, including naloxone (Narcan) and other approved formulations.

The law takes effect on December 13, 2026.

Anticipated Regulations to Address Outstanding Issues

The amendments direct the New York State Department of Labor (“NYSDOL”) to issue regulations. Outstanding issues that may be addressed by such regulations include: 

• The number of antagonists required per workplace.  The statute leaves the number of doses and precise placement for the NYSDOL to specify in regulations. Employers should expect guidance that scales with workforce size, layout, and risk profile.
• Employee training on usage and access.  The statute contemplates training of employees on use of the opiod antagonist, but does not specify the content.  Forthcoming regulations will likely clarify who must be trained, what curriculum is sufficient, and refresher frequency.
• Storage and availability parameters.  Because Naloxone has a finite shelf life, employers will likely need to develop processes for expiration tracking, replacement, and incident logs consistent with first‑aid practices.

Practical Implications for Employers

In advance of the December 2026 effective date, employers should take the following steps:

• Confirm Coverage.  Determine which locations are federally required to maintain first‑aid supplies under OSHA’s first‑aid standard.
• Plan Procurement.  Identify formulations (e.g., nasal spray) and quantities appropriate for the employer’s footprint, with a placeholder assumption to adjust when NYSDOL regulations issue.
• Draft/Update Protocols.  Update first‑aid/medical emergency SOPs to cover storage, accessibility, incident response, post‑incident documentation, and restocking.
• Prepare Training.  Identify the cohorts to be trained and outline a brief, practical training program (recognition, activation of EMS, administration, documentation), pending state rulemaking.
• Monitor Rulemaking.  Track NYSDOL/DOH regulations and update plans once stocking and training specifics are issued.
• Multi-Jurisdiction Compliance.  Ensure compliance with similar requirements in various jurisdictions, including California (see here).

In the short-term, employers with OSHA triggered first aid obligations should begin planning for procurement, storage, training, and inventory controls, while monitoring regulations from the NYDOL.
