Personal protective equipment remains a core workplace control, but connected technologies are changing how safety teams monitor hazards and respond to risk. OSHA requires employers to conduct a PPE hazard assessment, select appropriate protection, and ensure affected employees use it. Smart PPE adds sensors, communications, location data, or other digital capabilities to that safety framework.
Wearables are not the only option. NIOSH describes advanced sensor technologies as including wearable and placeable systems, each suited to different types of workplace information. For visible requirements such as hard hats, safety vests, bump caps, gloves, or hairnets, computer vision can verify compliance through existing cameras without requiring a connected device on every worker. Wearables remain relevant when the safety requirement involves physiological measurements, gas exposure, remote communication, or worker-specific proximity alerts.
Safety teams should begin with the hazard rather than the device category.
Important questions include:
These questions help distinguish situations where wearables are necessary from those where existing infrastructure can provide the required visibility.
Voxel takes a different approach from worker-worn safety devices. Its PPE detection platform uses existing security cameras to continuously monitor designated areas for missing protective equipment rather than requiring every employee to carry or wear a connected sensor.
That approach is designed for visible compliance requirements. Current detection capabilities include missing hard hats, safety vests, bump caps, hairnets, and high-visibility gloves in areas where those items are required.
When Voxel identifies a compliance event, safety teams receive video context showing where and when it occurred. Events can be reviewed, assigned for follow-up, incorporated into coaching, and included in dashboards and multi-site trends.
This creates a different data model from smart PPE. A connected helmet or wearable typically generates information about the person carrying the device. Voxel instead uses existing camera coverage to identify patterns across monitored work areas, which can help teams determine whether compliance is declining around specific shifts, entrances, production zones, or work processes.
Voxel reports compatibility with more than 95% of existing CCTV cameras and a 48-hour deployment timeline per site. Its PPE page currently reports 95%+ detection accuracy for site-specific models.
Published results also include PPE-specific outcomes. Carlex Glass reported an 86% increase in safety vest compliance in under three months. NSG reported a 62% reduction in safety vest incidents during the first 30 days at a U.S. facility.
For enterprises primarily trying to verify visible PPE use consistently across facilities, Voxel provides an alternative to adding connectivity to every piece of protective equipment.
Honeywell offers connected-worker technologies that combine safety software with compatible gas-detection equipment and other industrial safety devices.
Honeywell Safety Suite can provide centralized information from connected worker-safety equipment. Current Honeywell offerings include wearable and portable gas detection, location-aware worker monitoring, alerts, and equipment-management functions.
This type of system addresses safety conditions that may require direct sensor readings from the worker or surrounding environment rather than visual PPE verification alone.
MSA's ALTAIR io 4 is a connected portable gas detector within the MSA Connected Work Platform.
The wearable monitors configured atmospheric gases and connects with MSA's cloud-based safety environment. Safety teams can use the connected platform to manage devices and review information generated by gas-detection equipment.
This category is designed for atmospheric hazard monitoring. It performs a fundamentally different function from visual systems that verify whether an employee is wearing required protective equipment.
3M's Connected Safety offering applies IoT connectivity to worker, equipment, and safety-management workflows.
The platform can connect information from compatible safety equipment and support digital compliance workflows. 3M also offers connected communication and hearing-protection products, including PELTOR headsets with wireless communications capabilities.
These tools are used where PPE itself needs communications, equipment information, or connected workflow functionality rather than simple visual confirmation that the equipment is present.
Aatmunn is the current company name of the business previously known as Guardhat. The company has expanded from its original smart-hard-hat focus into a broader connected-worker and industrial-safety platform.
The platform brings together information involving workers, workplaces, equipment, and industrial assets. Its scope includes worker connectivity, location-related safety applications, equipment information, and operational workflows.
Organizations evaluating the former Guardhat technology should therefore assess Aatmunn's current platform rather than treating Guardhat as a separate active smart-PPE vendor in 2026.
SHEQSY is a lone-worker safety application that can operate through employees' smartphones and compatible connected devices.
Available functions include real-time location sharing, periodic check-ins, overtime alerts, duress activation, safety forms, hazard reporting, and emergency workflows.
SHEQSY addresses situations in which workers operate alone or away from direct supervision. Its purpose differs from PPE compliance detection because it focuses primarily on worker status, communication, and escalation.
Garmin's inReach Professional offering provides satellite communication for organizations with employees operating where conventional mobile networks may be unavailable.
Compatible inReach devices support satellite messaging, location information, tracking, and interactive SOS functions with an active service plan.
Organizations can also manage multiple professional devices and users through enterprise subscription arrangements.
This type of connected safety device applies primarily to remote and field operations where maintaining communications is itself an important safety requirement.
Kenzen develops worker-monitoring technology focused on heat stress, fatigue, readiness, and related physiological conditions.
Its systems use worker-specific data and monitoring to help organizations identify signs associated with heat strain or fatigue risk.
These use cases illustrate where wearable sensing provides information that fixed cameras cannot. Whether a worker has a hard hat can be visually verified, but internal physiological conditions require a different measurement approach.
Blackline Safety's G8 is a connected industrial wearable that combines several worker-safety functions within one device.
Available configurations include multi-gas detection, lone-worker protection, real-time location data, alerts, and two-way communications. Safety information can be transmitted to Blackline's connected software environment for monitoring and response.
The G8 therefore addresses worker-specific hazards requiring direct measurement or communication, particularly atmospheric exposure and lone-worker scenarios.
Vuzix produces enterprise smart glasses for manufacturing, warehousing, field service, inspections, and related industrial workflows.
Devices such as the M400 provide hands-free access to digital information and can support remote assistance, documentation, instructions, and communication with off-site specialists.
Smart glasses sit at a different point in the connected-worker category. Their primary role is delivering information and visual communication to the wearer rather than continuously verifying conventional PPE compliance across the site.
Camera-based analytics should not be treated as a universal replacement for connected safety devices.
Wearables and sensors remain appropriate when the measurement itself needs to come from the worker or immediate environment.
Examples include:
In these situations, replacing a sensor with a camera would remove information the safety team needs.
The key is to avoid deploying connected devices for a problem that does not actually require worker-level sensing.
Voxel is most directly relevant when the central question is not what condition is the worker experiencing, but is the required PPE being used consistently across the operation?
Its AI safety platform can continuously evaluate camera-covered areas and turn individual PPE detections into site-level information. That allows safety teams to see whether a compliance issue is concentrated around a particular location, time period, or operating process.
This distinction is useful for enterprises with large or distributed workforces. Rather than treating every missing vest or hard hat as an isolated event, teams can look for patterns and decide whether the response should involve coaching, signage, supervisor communication, work-area changes, or another corrective measure.
Customer results provide PPE-specific evidence. Carlex reported an 86% increase in safety vest compliance, NSG reported a 62% reduction in safety vest incidents during its first 30 days at a U.S. facility, and the Port of Virginia reported a 15% reduction in safety vest violations within six months.
Those results are individual customer outcomes rather than universal performance expectations. They show how continuous PPE visibility can support a more measurable compliance program.
Organizations assessing whether their current cameras can support this approach can request a Voxel demo and evaluate coverage against the specific PPE zones they need to monitor.
No. Cameras and connected wearables provide different types of information. Camera analytics can verify visually detectable requirements such as hard hats or safety vests, while smart devices may be needed for gas sensing, physiological monitoring, satellite communication, or worker-specific alerts. Voxel risk monitoring is therefore most relevant when the required safety condition can be identified through existing video coverage.
Capabilities depend on the platform, camera view, site conditions, and configured requirements. Computer vision can be used for visually identifiable protective equipment such as hard hats, safety vests, bump caps, gloves, or hairnets when those items are visible to the camera. It should not be assumed to determine protection characteristics that cannot be seen in the footage.
Privacy considerations apply to both wearables and camera systems because each can generate information about workers or workplace activity. Employers should evaluate what information is collected, who can access it, how long it is retained, and how the technology will be used operationally. Voxel discusses these concerns in its guidance on union safety technology, including the role of privacy controls and transparent implementation.
Yes. When detections are aggregated over time, safety teams can examine whether visible PPE issues are recurring in particular areas or operating periods. This can support coaching and process improvement rather than relying only on isolated observations. Voxel's PPE compliance monitoring connects this concept with broader measurement of PPE-related leading indicators.
Start with the hazard and the information required to manage it. If the safety team needs physiological, environmental, communication, or worker-specific sensor data, a connected device may be appropriate. If the requirement is consistent visual verification of PPE across camera-covered areas, computer vision may address that layer without adding a connected device solely for compliance checking.
