Introduction

California’s Senate Bill 553 (SB 553) made workplace violence prevention requirements effective and enforceable on July 1, 2024. Employers subject to the law must establish and implement a Workplace Violence Prevention Plan (WVPP) and supporting elements such as training, recordkeeping, and incident documentation.

A practical way to “operationalize” SB 553 is to run workplace violence prevention like a risk mitigation cycle: identify hazards, evaluate risk, implement controls, and document corrective actions; those steps align with SB 553 requirements. That cycle will feel familiar to most EHS/IH practitioners; it’s the core risk-control process used for routine safety risks and complex exposure problems alike.

SB 553 is also written to require active employee involvement in key parts of the program, including participating in identifying and evaluating workplace violence hazards and reviewing incident-related information, with input mechanisms designed to capture concerns from the people doing the work. That employee engagement is a practical prerequisite for surfacing early warning signs and making the program usable day-to-day. This “grassroots” approach supports psychological safety by valuing employee perspectives, making reporting pathways accessible, and closing the loop with timely follow-through.

Case Summary

A California employer requested a comprehensive workplace violence prevention hazard assessment to support WVPP compliance. The assessment involved a review of the existing WVPP, a systematic walkthrough using a standardized hazard inspection form, and informal employee interviews to identify work-area concerns and operational realities.

Interpersonal concerns did come up during employee interviews. But the less obvious takeaway was how the built environment can function as a risk multiplier, providing opportunities for the concealment of inappropriate behavior and reducing the organization’s ability to detect, respond, and corroborate events.

How the Hazard Works

Every year in California, workplace violence is linked to roughly 60 deaths and about 10,000 injuries requiring time off work. Workplace violence hazards often discussed as industry-specific, interpersonal conflict, or discrete events. In this case, the risk profile was even greater in scope because it was compounded by environmental conditions.

Several mechanisms are worth calling out:

• Unsecured gates, propped-open doors, and breaches in perimeter fencing creates opportunities for unauthorized access.
• Poor lighting and surveillance gaps in remote areas can delay detection/response, and limit the ability to corroborate events.
• Public-facing roles (ticketing, security, retail, food service) at arm’s length with limited physical separation. In such conditions, staff have a narrower margin to de-escalate, disengage, or summon help.
• “Opt-in” emergency alerts and a manual telephone tree could create gaps when every minute counts.
• Working alone or in remote areas (especially after hours) can place certain individuals in vulnerable positions.

From an EHS/IH standpoint, some of these are familiar patterns. Risk cannot be eliminated entirely, but controls (and gaps) materially influence likelihood and severity of violent incidents. The goal of prevention is to reduce the probability and severity of foreseeable scenarios by addressing controllable hazards early (and continuously).

Anticipate → Recognize → Evaluate

A practical WVPP can be strengthened by treating program implementation as a repeatable cycle.

1. Anticipate: Start by identifying credible scenarios based on employee input and environmental conditions. In this case, a credible scenario might involve an unauthorized person bypassing security check via an unsecured gate with criminal intent. The objective is to anticipate where exposure and escalation potential are higher so you can prioritize controls.
2. Recognize: Review the written program, perform systemic walkthroughs, and interview employees. The latter is particularly valuable for surfacing early indicators that would not appear in written procedures.
3. Evaluate: Convert observations into actionable findings, rank them by risk and feasibility, and assign clear ownership. A prioritized list with clear ownership prevents “security issues” from becoming “everyone’s issue” and therefore no one’s, especially on complex sites with multiple employers and/or public access.

Checklist

You can use the following checklist as an aid to assess your WVPP:

☐ Do you have a WVPP that meets SB 553 requirements and reflects day-to-day operations?

☐ Are employees actively involved in identifying hazards? Do you have a systemized way of capturing employee input?

☐ Can staff summon help in under one minute from anywhere they work, including remote areas and after hours?

☐ Are public-facing workstations evaluated for safety risks (sufficient physical barrier, availability of radios or panic buttons, de-escalation support, and speed of response)?

☐ Are access points controlled in practice (not just in policy), including during peak traffic and off-hours conditions?

☐ Are lighting and surveillance coverage adequate and comprehensive? Do they cover parking lots and remote areas?

☐ Are duress tools and emergency communications consistent across all work areas (no “coverage islands”)?

☐ Is the reporting pathway comprehensive and effective (clear intake options, timely response, documented follow-through)?

☐ Are corrective actions tracked to closure, with a documented check that controls are functioning as intended?

Closing

A WVPP is more useful when treated as a living risk mitigation process rather than a one-time compliance task. The assessment process described here presents a practical point for the EHS/IH community: interpersonal concerns will surface in any workplace, but the built environment plays a role in how much opportunity exists and how quickly help arrives. By integrating employee input into hazard identification and corrective actions, organizations can reduce the risk of workplace violence in a way that is measurable and defensible.
