The Warehouse Worker Injury Reduction Program is part of New York’s Warehouse Worker Protection Act. Starting June 1, 2025, covered employers must establish and implement an injury reduction program designed to identify and minimize the risk of work-related musculoskeletal disorders for warehouse workers who perform manual material handling tasks. These tasks can include lifting, lowering, pushing, pulling, carrying, holding, or restraining objects. (New York State Department of Labor., 2025.-a; New York State Department of Labor., 2025.-b).
For warehouse operators, safety professionals, and ergonomics teams, the central question is straightforward: how can the organization turn a legal requirement into a practical injury-prevention program? This guide summarizes the core requirements and explains how an ergonomics-led approach can support both compliance and safer, more sustainable work.
What is the Warehouse Worker Injury Reduction Program?
The WWIRP is part of New York’s Warehouse Worker Protection Act. It requires covered employers to establish and implement an injury reduction program that identifies and minimizes the risk of work-related musculoskeletal disorders among workers who perform manual material handling tasks. Examples include lifting, lowering, pushing, pulling, carrying, holding, and restraining objects.
A compliant injury reduction program must include:
- A written worksite evaluation that identifies and assesses ergonomic risk factors.
- Actions to eliminate or reduce workplace factors and conditions that may contribute to musculoskeletal disorders.
- Injury reduction training for affected employees and their supervisors.
- Appropriate on-site medical and first-aid practices, where applicable.
- Meaningful employee feedback and input during program development and implementation.
Who is covered by New York’s WWIRP?
The Warehouse Worker Protection Act applies to employers that directly or indirectly employ, or control the wages, hours, or working conditions of:
- 100 or more employees at a single warehouse distribution center in New York State; or
- 1,000 or more employees across one or more warehouse distribution centers in New York State.
Covered employees generally work at a warehouse distribution center, are subject to quotas, and are not exempt from minimum wage or overtime requirements. Drivers and couriers travelling to and from a warehouse are excluded from the employee coverage described by the state.
The written worksite evaluation is the foundation of compliance.
The worksite evaluation is not a generic safety checklist. It must be written, completed by a competent person, and informed by workers who perform the jobs being evaluated. The evaluation must identify both existing and predictable ergonomic risk factors that have caused, or are likely to cause, work-related musculoskeletal disorders.

The assessment must reflect the actual warehouse operation
When must the evaluation be updated?
When is a board-certified ergonomist required?
A board-certified ergonomist is not automatically required to conduct every initial worksite evaluation. However, when a workplace safety committee—or another active employee-led committee where no formal safety committee exists—raises a health and safety concern and requests a review in writing, the employer must have the evaluation reviewed by a board-certified ergonomist. The state’s employer FAQ says this review must be completed within 30 days of the request.
After the review, the employer must address any additional risks that are identified. Risks should be eliminated where feasible; when complete elimination is not possible, exposure must be minimized as much as possible.
How should employers reduce warehouse ergonomic risk?
The most effective programs follow the hierarchy of controls: redesign the job to reduce the source of exposure, then use administrative measures to support the physical improvements. Training is important, but training alone cannot remove excessive force, poor layout, high repetition, or unrealistic work pace.
Start with engineering and physical controls
Potential improvements may include:
- Lift assists, hoists, vacuum lifters, or conveyors that reduce manual lifting and carrying.
- Adjusted shelving and workstation heights that reduce bending and overhead reaching.
- Improved material flow so items arrive closer to the point of use.
- Reduced horizontal reach distances and fewer awkward transfers.
- Redesigned tools, handles, or packaging that improve grip and reduce force or vibration.
- Adjustable fixtures and equipment that accommodate different workers and tasks.
Use administrative controls to support the redesign
Administrative controls can reduce the duration or frequency of exposure. Examples include:
- Task rotation that genuinely changes the physical demands placed on the body.
- Staffing and workload adjustments during high-volume periods.
- Realistic pace expectations where quotas influence exposure.
- Break schedules that provide meaningful recovery time.
- Supervisor training on early warning signs and escalation procedures.
- Follow-up observations and worker feedback to confirm that controls are working.
Administrative measures should not become a substitute for feasible physical improvements. Rotating workers through several high-risk tasks, for example, may redistribute exposure without adequately reducing it.
What does WWIRP training require?
Employers must provide injury-reduction program training once a year to employees who perform manual material handling and to their supervisors. The training must occur during normal work hours, be paid, and use language and vocabulary the workers understand.
Training must address topics including:
- Early symptoms of work-related musculoskeletal disorders and the importance of early reporting.
- Ergonomic risk factors and the hazards associated with excessive work rates.
- Methods for reducing risk through workstation changes, work-practice changes, pace adjustments, and breaks.
- The employer’s specific injury reduction program.
- Relevant musculoskeletal treatment plans prepared by a medical professional.
- The rights and functions of workplace safety committees.
- Employee rights to report hazards, injuries, risk factors, and safety concerns without retaliation or discrimination.
Common WWIRP compliance and ergonomics pitfalls.
Treating training as the entire program
Training supports safe work, but it does not replace the written evaluation, worker involvement, corrective action, and documentation required by the program.
Using one generic assessment for the whole warehouse
A broad warehouse checklist can miss differences between shifts, processes, workstation layouts, product sizes, and quota expectations.
Ignoring pace and quotas
Productivity pressure is part of the required analysis when workers exposed to ergonomic risk factors must meet quotas.
Failing to document corrective action
Employers must keep written records of the steps taken to reduce or eliminate musculoskeletal disorder risk.
Missing annual and change-driven updates
The evaluation must be updated annually and reassessed within 30 days when certain new or changed work may increase risk.
Implementing controls without checking effectiveness
A control that looks good on paper may create a new reach, bottleneck, or handling step. Follow-up observation and worker input are critical.
A practical 30-60-90 day implementation roadmap.
First 30 days: establish scope and immediate priorities
- Confirm coverage under the Warehouse Worker Protection Act.
- Identify manual material handling tasks, quota-driven work, and affected employees and supervisors.
- Appoint or retain a qualified competent person.
- Collect worker feedback, existing injury data, discomfort reports, and process documentation.
- Identify urgent hazards that can be corrected immediately.
Days 31-60: complete and document the evaluation
- Evaluate relevant jobs, processes, shifts, and operations.
- Document exposure to force, repetition, posture, pace, contact stress, vibration, and temperature.
- Record quota requirements and possible consequences for workers.
- Prioritize risks using a consistent assessment method.
- Create corrective-action plans and schedules for changes requiring more than 30 days.
Days 61-90: implement, train, and verify
- Implement feasible engineering controls and supporting administrative controls.
- Deliver annual employee and supervisor training.
- Review applicable medical and first-aid station practices.
- Share required evaluation information and maintain accessible records.
- Set dates for follow-up verification, annual updates, and reassessment when work changes.
Why warehouse ergonomics matters beyond compliance.
Compliance may be the immediate trigger, but well-designed ergonomics programs can also support operational performance. Reducing unnecessary physical demand may improve worker comfort, consistency, quality, retention, and productivity while reducing the likelihood and cost of strains, sprains, and cumulative trauma claims.
The goal is not simply to teach workers to tolerate a demanding task. It is to design work that better matches human capabilities, provides realistic recovery, and prevents predictable exposure from becoming an injury.

Frequently asked questions about the New York WWIRP.
When did the New York Warehouse Worker Injury Reduction Program take effect?
The WWIRP took effect on June 1, 2025, for employers covered by the Warehouse Worker Protection Act.
Using one generic assessment for the whole warehouse
A broad warehouse checklist can miss differences between shifts, processes, workstation layouts, product sizes, and quota expectations.
Does every warehouse in New York need a WWIRP?
No. Coverage depends on employer size and whether the workplace meets the law’s warehouse distribution center criteria. The threshold is generally 100 or more employees at one covered warehouse distribution center or 1,000 or more across covered New York warehouse distribution centers.
Who can perform a WWIRP worksite evaluation?
The evaluation must be completed by a competent person capable of assessing existing and predictable ergonomic risk factors. Examples include ergonomists, industrial hygienists, certified safety professionals, and other qualified health and safety professionals.
Does the initial evaluation always require a board-certified ergonomist?
No. A board-certified ergonomist is specifically required to review the evaluation when an eligible workplace safety committee or employee-led committee submits a written request based on a health and safety concern.
How often must a WWIRP worksite evaluation be updated?
The evaluation must be reviewed and updated annually. A new evaluation is also required within 30 days when a new or changed job, process, or operation could increase musculoskeletal disorder risk.
Is annual training enough to comply with the WWIRP?
No. Training is one element of the program. Employers also need a written worksite evaluation, risk-reduction measures, worker involvement, documentation, and applicable medical and first-aid practices.
Key takeaway.
New York’s Warehouse Worker Injury Reduction Program requires a systematic approach to manual material handling risk: evaluate the real work, involve the people doing it, address pace and quotas, prioritize physical improvements, train employees and supervisors, document actions, and keep the program current. Done well, the result is more than a compliance file—it is a practical framework for safer and more sustainable warehouse operations.
