In theory, hazard communication is one of the most mature areas of workplace safety. OSHA’s Hazard Communication Standard has existed for decades, built on a simple premise: workers have the right to know what chemicals they are exposed to and how to protect themselves.
Yet in 2025, hazard communication remains the second most frequently cited OSHA violation with 2,546 reported cases.
This is not because hazards are unknown. It is because risk information fails to stay connected to real work conditions. On modern industrial sites, chemicals move, tasks change, contractors rotate, and environments evolve hour by hour. Labels remain static. Safety Data Sheets sit in systems rarely consulted mid-task. Training occurs weeks or months before exposure.
The result is a widening gap between what OSHA expects hazard communication to achieve and how it functions in practice. This is where AI for hazard communication finds its importance.
Hazard Communication: A Regulation That Should Work—But Often Doesn’t
At its core, the Hazard Communication Standard (1910.1200 ) is straightforward. Employers must ensure that workers understand:
What hazardous chemicals are present
The risks they pose—immediate and long-term
How to handle, store, and respond to exposure safely
In theory, this is addressed through labels, Safety Data Sheets (SDS), and training. But when observed in practice, these mechanisms are episodic, while exposure is continuous.
Hazard communication failures often occur because it assumes stable conditions—fixed tasks, predictable environments, and uninterrupted attention, while modern industrial sites operate very differently.
Chemical exposure today occurs across:
Dynamic workflows and shift changes
Temporary work zones and contractor activities
Combined risks from heat, dust, confined spaces, or mechanical operations
Under these conditions, hazard communication becomes less about whether information exists and more about whether it is visible, timely, and actionable at the moment of risk.
What OSHA’s 2025 Data Really Tells us About Workplace Hazard Awareness
OSHA’s continued citation of hazard communication failures is not simply about missing labels or incomplete SDS binders.
Recurring Cases of Hazard Communication Failures:

In many cases, documentation is technically present—but not functionally effective.
For example, OSHA investigations frequently identify situations where workers had completed hazard communication training, yet still mixed incompatible chemicals, bypassed ventilation controls, or removed respiratory protection mid-task. These are not failures of regulation—they are failures of situational awareness.
How AI for Hazard Communication Changes the Definition
AI does not replace labels, SDS, or training. Instead, it augments them with continuous, real-world context.
AI-powered systems—using computer vision, video analytics, edge processing, and connected wearables—enable hazard communication to shift from static instruction to dynamic awareness.
Rather than asking, “Was the information provided?”, AI reframes the question to: “Was the risk visible at the moment it mattered?”
AI in Action: Closing the Hazard Communication Gaps on Industrial Sites
Hazard communication failures rarely stem from missing policies. But more often, they arise in the gap between documented controls and real work conditions. AI bridges this gap by turning hazard communication into a continuously verified, data-driven safety layer that operates in real time on active industrial sites.
Here’s how:
Visual Verification of Hazard Communication in Practice
AI video analytics-enabled hazard communication provides instant verification, not assumption.
Rather than relying on periodic audits or manual checks, AI systems continuously scan active work zones through AI CCTVs or AI-based drones to confirm that chemical containers are properly labelled, warning signage remains visible, and hazard indicators have not been obstructed by operational changes.
This is particularly critical in environments where containers are moved frequently or temporary storage becomes routine.
For example, in manufacturing facilities handling corrosive cleaning agents, AI can identify when chemicals are transferred into unlabelled or incorrectly labelled secondary containers—a frequent OSHA citation point. While SDS may exist centrally, the moment a container loses its identifier, hazard communication effectively collapses at the point of use.
AI surfaces this gap immediately, allowing corrective action management before exposure occurs.
Also in large warehouses or processing plants, AI-powered systems for monitoring can detect when required hazard signage becomes obscured by stacked materials, mobile equipment, or temporary barriers—conditions that often arise mid-shift and go unnoticed until an incident or inspection.
Linking Exposure to Task Activity
Traditional hazard communication identifies what is hazardous, but rarely connects it to how work is actually performed. Vision AI-based monitoring systems close this gap by linking worker presence, task duration, and environmental context to known chemical risks.
They can track how long workers remain within chemical zones, how frequently they handle hazardous material management (HAZMET), and how environmental conditions such as ventilation or confined space constraints influence risk levels.
This creates a task-based exposure profile, rather than a static risk register.
In chemical processing plants, this has enabled EHS teams to identify maintenance activities that generate repeated short-term exposure—each individually within limits, yet cumulatively exceeding acceptable thresholds over a shift or week. On paper, procedures were compliant. In practice, exposure patterns told a different story.
PPE Compliance as a Communication Signal
PPE non-compliance is often treated as a behavioural issue. In reality, it is frequently a communication failure.
AI-enhanced PPE detection modules do more than flag missing equipment—it highlights where and when hazard awareness breaks down. If workers consistently remove gloves during certain tasks or adjust respirators during prolonged chemical handling, it signals that the perceived risk does not align with actual exposure.
In pharmaceutical and food manufacturing environments, for example, AI has identified patterns where workers remove eye protection during cleaning cycles because tasks are viewed as routine. These insights prompted EHS teams to reframe hazard communication—emphasising splash risks during specific cleaning motions rather than general chemical warnings.
AI also enables activity-based PPE validation, ensuring that the type of PPE worn matches the task being performed, not just the zone entered.
Lockout/Tagout as a Hazard Communication Challenge
Lockout/tagout (LOTO) failures are often cited as procedural violations, but at their core, they represent a breakdown in hazard communication around stored energy and chemical release risk.
AI systems can visually verify whether lockout devices and tags are present, correctly applied, and maintained throughout the task duration. More importantly, they can detect when workers enter equipment zones before isolation steps are completed—something documentation alone cannot prevent.
In industrial maintenance scenarios, AI has been used to identify repeated instances where contractors begin preparatory work while energy isolation is partially complete. While LOTO procedures were formally trained and documented, AI revealed that hazard awareness faded during transitional moments—shift changes, task handovers, or time pressure.
Label Integrity and Identifier Continuity
Labels are the backbone of hazard communication, yet they degrade faster than most safety systems account for.
AI can continuously verify label presence, legibility, and correctness on chemical containers, pipelines, and equipment. This is especially valuable in harsh environments where labels fade, peel, or are removed during cleaning or maintenance.
In oil & gas and heavy manufacturing sites, AI has detected pipelines carrying hazardous substances that no longer display visible identifiers due to insulation changes or repainting. While records remained accurate, frontline workers lacked immediate visual confirmation—creating exposure risk during routine tasks.
Data-Led Hazard Communication Intelligence
Perhaps the most transformative aspect of AI is its ability to convert observations into actionable safety intelligence. AI systems aggregate data across:
Repeated exposure-prone tasks
PPE non-compliance patterns
Labelling and signage failures
LOTO deviations
This allows EHS leaders to move beyond reactive corrections and prioritise systemic fixes—redesigning workflows, adjusting task sequencing, improving ventilation, or updating communication methods where breakdowns repeatedly occur.
Example of Data-Led Hazard Communication:
Suppose in a solvent-handling manufacturing unit, AI monitoring over 60 days flagged that nearly 4 in 10 chemical transfer tasks involved workers briefly removing gloves during refilling and cleaning steps.
While no incidents were reported, data showed the behaviour recurring most frequently during short-duration tasks and night shifts.
By correlating task duration, PPE usage, and chemical volatility, EHS teams identifies the real risk:
“Repeated low-duration exposures accumulating into a high chronic exposure profile” —a hazard invisible in incident logs or training records. |
This data-led insight allows safety leaders to classify the operation as a high-exposure task, triggering workflow redesign and improved hazard communication—before any injury or regulatory breach occurs.
Continuous Reinforcement Without Disruption in Multi-Employer Worksites
OSHA frequently cites hazard communication violations on sites with multiple employers—construction projects, turnaround maintenance, logistics hubs.
AI-supported systems provide a shared, visual layer of hazard awareness that does not rely on organisational boundaries. Whether a worker is permanent staff or a contractor, risk detection and alerts remain consistent.
This helps eliminate one of OSHA’s most common findings: workers unaware of site-specific chemical hazards introduced by other teams.
Unlike training sessions or audits, AI does not rely on memory, motivation, or presence. It provides continuous, context-aware reinforcement, alerting workers and supervisors through Generative AI co-pilots when conditions drift from safe operating limits.
This reinforcement happens in the background, without slowing production or increasing administrative load, making hazard communication an always-on function, rather than a periodic activity. Over time, this creates a feedback loop where hazard awareness becomes embedded in daily operations, not dependent on reminders or inspections.
Why AI Is Especially Effective for Long-Term Workplace Hazard Awareness
Chemical injuries are often invisible until they are irreversible. This explains why major players in the manufacturing sector, like Ford, Coca-Cola, Hyundai, and Amazon, have used AI-based technologies like computer vision to reduce hazards and improve workplace safety standards.
AI-driven hazard communication supports:
Early identification of exposure trends
Prioritisation of engineering or process controls
Data-backed justification for procedural changes
Hazard communication was never meant to stop at labels and training sessions. OSHA’s data makes this clear. AI finally gives it the situational intelligence needed to work on modern worksites.
