4. Safety Information and Warnings

WARNING: This device is part of a personal fall arrest system. Improper use or failure to follow instructions can result in serious injury or death. Only trained and competent persons should use this equipment.

• Always inspect the device, harness, and lifeline system before each use. Look for cuts, fraying, deformation, corrosion, or any other signs of wear or damage.
• Ensure the device is correctly attached to your full-body harness's dorsal D-ring and the vertical lifeline cable. The anti-inversion device prevents incorrect attachment.
• This device is designed for use with compatible MSA Latchways vertical lifeline systems. Do not use with incompatible systems or components.
• Ensure adequate fall clearance is maintained below the work area to prevent striking lower levels or obstructions in the event of a fall.
• Do not modify the device in any way. Repairs must only be performed by MSA or an authorized service center.
• The device must be removed from service immediately after a fall arrest event, even if no damage is visible.
• Refer to all applicable local, state, and federal regulations (e.g., OSHA, ANSI Z359.1) regarding fall protection equipment and practices.

5. Setup and Installation

The MSA 3104L-00 Latchways Attachment Device is designed for straightforward connection to a compatible vertical ladder lifeline system and a full-body harness.

1. Connect to Harness: Attach the carabiner end of the Latchways device to the dorsal D-ring of your full-body harness. Ensure the carabiner gate is fully closed and locked.
2. Connect to Lifeline: Open the Latchways mechanism by following the "UP" arrow indicator on the device. Position the device around the vertical lifeline cable. Ensure the cable is properly seated within the device's channel.
3. Secure Device: Close the Latchways mechanism, ensuring it clicks securely into place. The anti-inversion feature will prevent incorrect closure.
4. Pre-Use Check: Before ascending, gently pull on the device to confirm it is securely attached to both your harness and the lifeline cable. Verify that the device moves freely along the cable when ascending or descending, but locks instantly when subjected to a sudden downward force.

6. Operating Instructions

Once properly installed, the MSA 3104L-00 Latchways Attachment Device allows for hands-free vertical movement along the lifeline.

• Ascending: As you climb the ladder, the device will slide smoothly upwards along the vertical lifeline cable. Maintain three points of contact with the ladder whenever possible.
• Descending: As you descend, the device will slide smoothly downwards. Control your descent rate.
• Fall Arrest: In the event of a fall, the internal mechanism of the device will instantly engage the lifeline cable, locking the device and arresting the fall.
• Post-Fall Procedure: After a fall, remain calm. If possible, attempt to self-rescue or await rescue. Once safely on the ground, the device must be immediately removed from service and inspected by a competent person or returned to MSA for evaluation. Do not reuse a device that has arrested a fall.
