Safety and ergonomics in industrial packaging: how to protect operators in automated lines

February 24, 2026

The end of the line is one of the most demanding and active areas of any industrial plant.
Handling boxes, strapping, films, or pallets involves physical effort, repetitive movements, and exposure to mechanical risks.

With proper automation and ergonomic design, it is possible to reduce injuries, increase safety, and improve work quality.
In this article, we explore how automated systems, collaborative robots, and IHRESS engineering help create safer, more efficient, and more human-centered environments in packaging processes.

The safety challenge at the end of the line

The end of the line concentrates multiple operations: forming, sealing, wrapping, palletizing… each with potential risks.
Among the most frequent accidents are:

Overexertion when lifting loads or stacking manually.
Impacts caused by unsynchronized machine movements.
Cuts, entrapments, or falls in transit areas.
Muscle fatigue and injuries caused by sustained postures.

Ensuring safety in this environment requires a combination of technology, training, and ergonomic design.

2. Most common risks in packaging and palletizing areas

The first step in prevention is identifying risks.
The most common include:

Manual handling of loads without mechanical assistance.
Inadequate working heights or hard-to-access areas.
Lack of physical guards or presence detection systems.
Excessive repetition or monotonous tasks leading to repetitive strain injuries (RSI).

Risk assessment must be continuous and part of the line design.
IHRESS integrates functional safety from the engineering phase, not as an afterthought.

3. Ergonomic design principles in industrial environments

A well-designed packaging area not only improves safety, but also productivity.
Key industrial ergonomics principles include:

Proper working height, avoiding forced bending or lifting.
Optimal reach distances: everything should be accessible without twisting.
Task rotation and active breaks to reduce fatigue.
Uniform lighting and clear signaling in risk areas.
Accessible design for maintenance and cleaning without awkward postures.

IHRESS collaborates with safety technicians to adapt lines to the physical and cognitive needs of operators.

How automation reduces risks and improves workplace health

Automation does not replace operators: it protects them and frees them from hazardous tasks.
IHRESS automated systems reduce exposure to heavy loads, repetitive movements, and noisy or high-risk environments.

Main benefits:

Less physical effort thanks to automated handling.
Greater precision and consistency, avoiding errors that cause accidents.
Reduced mental fatigue by eliminating monotonous tasks.
Integrated safety with sensors, guards, and coordinated automatic stops.

In short, an automated line is not only more productive, but also safer and more sustainable for people.

5. Collaborative robots and safe assistance systems

Cobots (collaborative robots) are a key advancement in industrial ergonomics.
Unlike traditional robots, they can safely share space with operators thanks to:

Force and speed limiting systems.
Proximity sensors.
Automatic stop systems upon contact detection.

Used in tasks such as palletizing, case packing, or line feeding, cobots reduce musculoskeletal injuries and improve ergonomics without sacrificing productivity.

IHRESS implements safe collaboration solutions, combining artificial intelligence, 3D vision, and CE-compliant control systems.

6. IHRESS cases: safe automation and workplace well-being

In a food plant, replacing manual palletizing with an IHRESS collaborative robot reduced repetitive strain injuries by 70%.
In another installation in the chemical sector, the integration of safety sensors and intelligent stop systems completely eliminated entrapment incidents.

Additionally, the ergonomic redesign of packaging stations made it possible to:

Reduce reported fatigue by 30%.
Improve handling speed by 15%.
Pass European safety audits without issues.

7. Conclusion: safety and technology, a shared objective

Safety and productivity are not opposing goals: they reinforce each other.
A safe plant is more efficient, stable, and sustainable.
With automated solutions, ergonomic design, and regulatory compliance, IHRESS helps companies protect people while optimizing production.

The future of industrial packaging is not only automated: it is safe, intelligent, and human-centered.
