Final answer:
The maximum number of people that can add a lock to a lockout system depends on the lockout device's capacity. Each worker must have their own lock on the equipment for safety, and the specific number accommodated is determined by the device or hasp in use.
Step-by-step explanation:
The maximum number of people that can add their lock to a lockout system when working on the same equipment is not fixed; it depends on the physical capabilities of the lockout device used in the process. Each device has a limited number of holes or attachment points to which workers can attach their individual locks. The main goal of a lockout/tagout system is to ensure that a piece of equipment is properly shut off and inoperable during maintenance or servicing work to ensure the safety of the workers.
These systems are critical for workplace safety, especially when multiple employees are working on the same piece of machinery. To accommodate more workers, lockout devices are designed to hold multiple locks, or a hasp may be used to hold more than one lock. The Occupational Safety and Health Administration (OSHA) requires that each employee performing lockout/tagout has control over their own lock, which means that every person working on the machine must be able to apply their own lock to the system.
