Enhancing Workplace Safety in the Manufacturing Industry with AI

AI-powered computer vision helps manufacturers spot common manufacturing safety issues when workers enter restricted areas, bypass interlocks, or access hazardous zones. 

EHS teams can review flagged events across multiple production lines in hours, not days, so they can address repeat shortcuts before someone gets hurt. That matters because a single interlock bypass can trigger downtime, investigations, and major fines.

Article highlights:

• One packaging manufacturer faced a £115,000 fine and a two-day production shutdown after an amputation accident linked to interlock bypassing.
• Review safety data from multiple production lines in one afternoon instead of spending days monitoring each line individually.
• Protex AI integrates with existing camera infrastructure to flag when workers enter interlocked gates, restricted zones, or hazardous areas.
• Create automatic documentation of safety violations to support compliance efforts during regulatory investigations.
• Identify specific locations and patterns where workers take unauthorized shortcuts, enabling targeted interventions.

How does AI improve manufacturing safety? 

AI computer vision integrates with existing CCTV to monitor industrial environments continuously. It uses machine learning algorithms to identify unsafe behaviors, such as unauthorized entry into restricted zones or interlock bypasses, in real-time. 

Many deployments keep privacy in mind by processing video on site and sharing only short, relevant clips for review.

Evolution of safety in the industrial workplace 

Manufacturing environments change fast, and safety controls need to keep pace with new equipment, new layouts, and shifting production demands. Automation reduced some exposure, but people still work near machines, vehicles, and pinch points, so teams need better visibility into daily risk.

‍

From manual labor to automated oversight 

Many manufacturers use manufacturing safety solutions and automation to reduce exposure, then rely on skilled teams to oversee operations and respond quickly when risks show up.

Managing high-risk zones in factory workplaces 

In a factory workplace, machinery must be accessible for maintenance, yet inoperative to prevent accidents. 

‍

The function of interlocks and machine guards 

Interlocks sit at the center of equipment safety. When a guard is lifted, a door opened, or a light curtain breached, the machinery halts until the guard is secured or the door is closed. In some cases, machinery cannot be accessed until it's de-energized and isolated. 

‍

The real cost of safety breaches 

Despite workplace safety measures, injuries, including amputations, occur annually due to interlock tampering or circumvention. Some opt for maintenance while machinery is operational, a hazardous practice that may lead to equipment damage, production delays, and penalties. In certain instances, people find unauthorized means, bypassing interlocks or accessing machinery through "backdoors."

Operational and financial impacts of accidents 

Manufacturing safety events result in lifelong disabilities, financial penalties, legal investigations, and damage to an organization's reputation.

Consequences of Safety Breaches - Real-world example 

In one accident, an engineer at a packaging manufacturer went inside a fixed perimeter machine guard and closed the interlock gate from the inside. He asked someone to switch the machine back on. 

His sleeve was drawn into the machine, and his hand was amputated. Although it was reattached, he hasn’t regained full control of the hand and continues to suffer pain. 

After the accident, the regulator wouldn’t let the machinery be used for two days while they investigated – that’s lost time, lost production, and lost confidence from clients due to delayed orders. 

18 months after the accident, the company was fined £115,000. There was evidence that this procedure had been allowed on multiple previous occasions, so the company was considered at fault.

Implementing proactive safety with computer vision 

To mitigate these risks and legal exposure, proactive safety measures matter. A system that flags interlock bypasses, stores a clear record, and supports worker coaching can strengthen compliance evidence during an investigation. 

Early alerts also give supervisors time to fix the conditions driving the shortcut before it turns into a serious event. Your safety team can’t spend the whole day watching footage for a single type of hazard.

Automating detection with Protex AI 

Protex AI offers an AI-driven computer vision system that helps you identify entries into restricted areas and interlock bypass using existing cameras. With this technology, you can establish rules to identify when individuals enter restricted areas, such as inside interlocked gates or behind production lines. 

Safety staff can then review data from multiple production lines in a single afternoon, rather than spending days on each one. This allows them to pinpoint where issues are arising and collaborate with workers to eliminate the need for unauthorized and hazardous shortcuts.
