Internal Traffic and Aisle Design: How to Create Safe Plant Flows and Reduce Accidents

In the daily operation of a distribution center, the coexistence of heavy machinery and pedestrians represents one of the most sensitive points for Occupational Health and Safety. As previously covered in our guide on Resolution SRT 960/15, the regulatory framework sets clear operational requirements. However, the real practical challenge lies in layout design and organizing traffic flows within the plant.

An improvised traffic scheme or a lack of physical boundaries increases the risk of pedestrian collisions at blind intersections. Below, we break down the key guidelines for structuring safe aisles and optimizing material movement without compromising worker safety.

1. Pedestrian Segregation and Aisle Sizing

The core principle of a safe warehouse is preventing pedestrians and forklifts from sharing the same lane without physical protection:

• Dedicated pedestrian walkways: Clearly paint and mark paths intended for personnel using high-traffic paint and physical barriers in high-volume machinery zones.

• Aisle width calculation: The clear width must account for the equipment's turning radius (whether a counterbalance forklift or a reach truck) plus the volume of the load, leaving a safe maneuvering margin on both sides.

• Structural protection: Install reinforced corner guards and metal barriers at rack ends to absorb potential scrapes or impacts during turning maneuvers.

2. Managing Blind Intersections and Traffic Directions

Intersections between storage aisles hold the highest incident rate due to a lack of frontal or lateral visibility:

• Parabolic mirrors: Position mirrors at every aisle corner so both drivers and pedestrians have clear sightlines before entering an intersection.

• One-way traffic flow: Design one-way traffic in narrow aisles to eliminate swerving maneuvers between two forklifts.

• Speed limit signage: Restrict indoor driving speeds (recommending no more than 10 km/h) with clear signage at every entry point to storage areas.

3. Active Visibility: Integrated Technology in the HELI Fleet

Beyond reorganizing physical space, it is crucial for forklifts to announce their presence before entering a crossing or blind spot. The HELI lineup integrates active safety systems built for accident prevention:

• Blue Spot and Red Zone projectors: They project a blue light beam onto the floor meters ahead of or behind the unit, or draw a red perimeter along the sides, alerting pedestrians to approaching machinery even in noisy environments.

• Presence and seatbelt sensors: Mechanisms that prevent unit movement unless the operator is properly positioned and buckled in the cab.

• Acoustic alarms and strobe beacons: Synchronized reverse alarms and factory-integrated 360° visibility lights.

Conclusion

Designing an efficient layout and organizing internal traffic is an operational decision that protects personnel and reduces costs from unscheduled downtime or damaged goods. Combining a well-mapped circulation layout with machinery equipped with visibility technology is the most solid path toward a safe and efficient plant.
