Group Lock Box in Pakistan Price Types Uses Benefits & Suppliers. Group Lock Box is a critical component of a Lockout-Tagout (LOTO) system used when multiple workers perform maintenance on the same equipment. It ensures that machinery cannot be re-energized until every authorized worker has removed their personal lock.
Group lock box systems follow international safety requirements set by the Occupational Safety and Health Administration (OSHA) and guidelines from the National Fire Protection Association (NFPA).
In Pakistan, industrial safety compliance falls under the Pakistan Standards and Quality Control Authority (PSQCA).
Group lock boxes are widely used in factories, oil & gas facilities, power plants, textile mills, construction projects, and large industrial shutdown operations across Pakistan.
Group Lock Box – Overview
A Group Lock Box is a secure metal or heavy-duty plastic box used to store the keys of lockout devices applied to energy isolation points.
Instead of placing multiple locks directly on equipment, one primary lock is used, and its key is placed inside the group lock box. Each worker then attaches their personal safety padlock to the box.
The equipment cannot be restarted until every worker removes their lock.
This ensures:
- Full worker protection
- Zero accidental energization
- Clear accountability
- Compliance with LOTO procedures
What Is a Group Lock Box?
A Group Lock Box is a centralized key control system for multi-worker lockout operations.
Main Components
- Heavy-duty steel or ABS plastic body
- Lockable lid
- Multiple padlock attachment points (6–24 holes typically)
- Internal key storage compartment
- Identification label area
- Carry handle (portable models)
It forms the core of group-based hazardous energy control.
How a Group Lock Box Works
1️⃣ Authorized supervisor isolates energy source.
2️⃣ Lockout devices (valve lockouts, breaker lockouts, plug lockouts) are applied.
3️⃣ Keys of those lockout devices are placed inside the group lock box.
4️⃣ Each worker attaches their personal safety padlock to the box.
5️⃣ Equipment cannot be energized until all personal locks are removed.
This prevents accidental startup while maintenance is ongoing.
