คู่มือการใช้งาน

1. บทนำ

The MSA Latchways Standard Self-Retracting Lifeline (SRL) is a critical component of a personal fall arrest system, designed to provide dependable fall protection. This device allows for unhindered movement while maintaining a constant tension on the lifeline, automatically retracting and extending as the user moves. In the event of a fall, the SRL's braking mechanism activates to arrest the fall quickly and safely, minimizing fall distance and impact forces. This manual provides essential information for the proper use, inspection, and maintenance of your Latchways SRL.

2. ข้อมูลด้านความปลอดภัย

คำเตือน: This device is for overhead use only. Failure to follow all instructions and warnings can result in serious injury or death. Always ensure proper training and understanding before using this equipment.

• Always inspect the SRL before each use for any signs of damage, wear, or malfunction.
• Ensure the SRL is securely attached to a suitable structural anchor point capable of supporting the required load.
• Connect the SRL to the dorsal D-ring of a full-body harness.
• Do not use the SRL if the lifeline does not retract smoothly or if the braking mechanism does not engage properly.
• Never use the SRL if it has been subjected to a fall arrest event, even if no visible damage is present. It must be removed from service immediately.
• Refer to all applicable local, state, and federal regulations (e.g., OSHA, ANSI) regarding fall protection equipment.
• Ensure adequate fall clearance is maintained below the working surface to prevent contact with lower levels or obstructions during a fall.

• ตัวเรือนทนแรงกระแทก: Provides durability and protection for internal components.
• 100% Full Contact Locking Mechanism: Guarantees secure engagement during a fall.
• Stainless Steel Chassis & Components: Offers corrosion resistance and extended lifespan.

4. การตั้งค่าและการติดตั้ง

1. การเลือกจุดยึด: Identify a structural anchor point capable of withstanding a minimum load of 5,000 lbs (22.2 kN) per worker attached, or meeting the requirements of a qualified person. The anchor point should be located directly overhead for optimal performance.
2. SRL Attachment to Anchor: Connect the top attachment point of the SRL to the selected structural anchor. Ensure the connection is secure and compatible with the anchor point. The OCR on the product image indicates "TO STRUCTURAL ANCHOR PORT" at the top of the device.
3. การเชื่อมต่อสายรัด: Attach the carabiner or hook at the end of the SRL's cable to the dorsal D-ring of your full-body harness. Verify that the gate of the connector is fully closed and locked.
4. Clearance Verification: Before beginning work, calculate and verify that sufficient fall clearance exists below the working surface to prevent striking any lower level or obstruction in the event of a fall.

5. คู่มือการใช้งาน

Once properly installed and connected, the Latchways SRL operates automatically. The cable will extend and retract as you move, maintaining slight tension to eliminate slack. This allows for freedom of movement while ensuring immediate fall arrest capability.

• Move within the working area, allowing the cable to extend and retract smoothly.
• Avoid sudden, jerky movements that could cause the unit to lock unnecessarily.
• In the event of a fall, the internal braking mechanism will engage, arresting the fall. Remain calm and await rescue.
• After a fall, the SRL must be immediately removed from service and returned to an authorized service center for inspection or disposal.

6. การบำรุงรักษา

Regular maintenance is crucial for the longevity and safe operation of your SRL.

• การตรวจสอบรายวัน: Before each use, visually inspect the entire unit, including the housing, cable, connectors, and labels, for any signs of damage, corrosion, cuts, fraying, or deformation. Ensure the cable retracts and extends smoothly.
• การทำความสะอาด: Clean the SRL with a damp cloth and mild soap solution. Do not use harsh chemicals or solvents. Allow to air dry completely before storage.
• พื้นที่จัดเก็บ: Store the SRL in a clean, dry environment, away from direct sunlight, extreme temperatures, corrosive chemicals, and sharp objects.
• การตรวจสอบเป็นระยะ: In addition to daily inspections, a competent person must perform a thorough inspection at least annually, or more frequently as required by local regulations or manufacturer guidelines.
• ความสามารถในการให้บริการภาคสนาม: This unit is designed to be field serviceable. Refer to the official MSA Latchways service manual for detailed instructions on authorized field maintenance procedures. Only trained and authorized personnel should perform service.
