What is the main purpose of an isolation log?

1. To document equipment failures

2. To record usage of isolation locks

3. To schedule maintenance procedures

4. To track employee training

The correct answer is: To record usage of isolation locks

The primary purpose of an isolation log is to record the usage of isolation locks. Isolation locks are critical safety devices used to ensure that machinery is completely shut down and cannot be inadvertently started while maintenance or repair work is being performed. The log serves as a formal record, documenting when and how isolation locks are applied, who applied them, and when they are removed. This documentation is essential for maintaining a safe working environment, as it helps to prevent accidents and ensures that proper lockout/tagout procedures are being followed. By keeping an accurate isolation log, organizations can ensure compliance with safety regulations and standards, enhance accountability, and provide a clear track of when equipment was isolated. This practice is vital in industries where heavy machinery is operated and maintenance work is frequent, ensuring that safety protocols are respected and upheld.
