# Safety Guarding: Protecting Your Employees, Protecting Your Business

Safety is an essential part of every ASC Machine Tools rollforming system. From the initial machine design through manufacturing and final testing, ASC engineers safety guarding to help protect operators and maintenance personnel from the moving components and potential hazards associated with automated metal-forming equipment.

ASC’s guarding systems are designed to meet applicable OSHA machine-guarding requirements. OSHA 29 CFR 1910.212 requires machine guarding to protect operators and other employees from hazards such as ingoing nip points, rotating parts, and points of operation. The standard recognizes several approaches, including barrier guards and electronic safety devices.

Rather than using a one-size-fits-all approach, ASC selects the guarding method based on the machine configuration, access requirements, visibility, and production application.

Hard Guarding: Maximum Physical Protection

For areas where operator access is not required during normal production, ASC commonly uses hard guarding.

These fixed guards create a physical barrier between personnel and hazardous moving components such as rollforming tooling, drive systems, shafts, chains, gears, and other moving machinery.

Hard guarding provides a durable solution for production environments where the equipment needs to operate continuously without routine access to the guarded area.

By physically separating personnel from moving components, hard guarding provides a straightforward and highly effective layer of protection while maintaining the rugged construction expected from industrial rollforming equipment.

Swing Door Guarding: Safe Access When Maintenance Matters

Some areas of a rollforming line require regular access for setup, tooling changes, inspection, or maintenance. In these locations, ASC can incorporate swing-door guarding with safety interlocks.

These access doors allow personnel to enter the guarded area when the machine is stopped while preventing normal operation when the guard is open.

ASC utilizes Allen-Bradley Guardmaster safety components for applications requiring monitored access.

The safety interlock becomes part of the machine's safety circuit, helping ensure that opening a guarded access door initiates the appropriate safety response.

This approach provides an important balance between operator protection and machine accessibility. Instead of requiring personnel to remove fixed guards whenever access is needed, swing doors provide controlled access while maintaining the machine's safety functions.

Plexiglass Guarding: Safety Without Sacrificing Visibility

In applications where visibility is critical, ASC can incorporate plexiglass guarding.

Clear guarding allows operators and maintenance personnel to observe the forming process, material movement, tooling, and other machine functions without exposing themselves to the moving components.

This can be particularly valuable during setup, troubleshooting, and production monitoring. Operators can see what is happening inside the guarded area while the physical barrier remains in place.

The result is a combination of visibility and protection—allowing personnel to monitor the machine without unnecessarily opening the guarded area.

Keyence Floor Scanners: Open Access Without Physical Barriers

For applications where a traditional physical guard is not practical, ASC can offer Keyence safety laser scanners as an additional guarding solution.

Floor scanners create a configurable safety zone around designated areas of the machine. When a person enters the protected area, the scanner detects the intrusion and sends a safety signal to the machine control system, initiating the appropriate safety response.

This approach can be particularly useful around areas where operators need frequent, unobstructed access to the machine or where physical fencing would interfere with material flow, production, or visibility.

Unlike a physical guard, a floor-scanning system does not require operators to open a door or move around a barrier simply to access an area. It can provide a clean, open machine layout while maintaining a defined safety zone.

Keyence scanners can also be configured for applications with different access and monitoring requirements, making them another tool ASC engineers can consider when developing the overall machine safety strategy.

Safety Designed Around the Machine

Every rollforming line presents different guarding requirements. A high-speed panel line, purlin line, decking machine, or trim rollformer may have different access points, moving components, and operator interaction requirements.

ASC therefore approaches guarding as part of the overall machine design.

Guarding is engineered around:

• Machine operating speeds

• Moving and rotating components

• Points of operation

• Operator access requirements

• Setup and tooling access

• Maintenance requirements

• Visibility requirements

• Emergency and safety circuits

• Overall line configuration

  
  

This integrated approach helps ensure that safety features work together with the machine controls and mechanical design rather than being added after the machine has already been engineered.

Safety and Productivity Can Work Together

Effective guarding should not make a machine unnecessarily difficult to operate or maintain. ASC's goal is to provide protection while allowing operators and maintenance personnel the access and visibility they need to efficiently run the equipment.

Hard guarding provides robust protection where access is unnecessary. Swing-door guarding provides controlled access where maintenance or setup is required. Plexiglass provides visibility where seeing the process is important.

Together, these options allow ASC to configure guarding around the actual needs of each machine.

Built Into Every ASC Machine

For ASC, machine safety is not simply about adding guards around moving equipment. It is about engineering the guarding, safety devices, access points, and controls as part of the complete machine.

From heavy-duty fixed guarding to interlocked swing doors and clear plexiglass panels, ASC provides multiple guarding solutions designed around the application.

The result is a safer, more accessible, and more productive rollforming system—engineered from the ground up with operator protection in mind.

Note: Specific guarding and safety-system configurations are selected based on the machine design and application. OSHA compliance requirements can vary by equipment, installation, and workplace conditions.
