Load Drop Zone (LDZ) Area
Note: These are the absolute MINIMUM requirements for a load drop zone
Safety Training: Technical Training
Personnel remain outside the LDZ Permission to enter is required from PIC Prior to lift, verify that:
• Load path is clear of obstruction and other activities
• Continuous, unobstructed ingress and egress path is established
• Controls for monitoring boundary of zone are established
• No one is allowed under the load
Passing a load over personnel or equipment requires “High Hazard Lift” planning
LDZ Requirements
When placing barricade tape to mark the boundaries of a load drop zone, red and black “DANGER” tape shall be used
Safety Training: Technical Training
1. Rigging Plan
2. Specific assignments
3. Communication methods
4. LDZ size and control
5. Safe egress
6. Load control
7. Load positioning
8. Emergency stop signal
9. Location of power disconnects
10. Contingencies
Pre-Job Briefings (PJB)
In addition to the required PJB items in the Plan Jobs Safely procedure, when lifting and rigging activities are planned, the following items need to be addressed:
Safety Training: Technical Training
Preferred Method of Load Control
Discuss in PJB
Long enough to clear LDZ
Never wrap around a body part
Attach as far away from center of gravity as possible
Trail the load
Use Shepherd’s Hook or similar device to reach tag line or to adjust cribbing
Load Control with Tag Line
Tag lines should also be long enough, or personnel positioned such, that the line is at an angle no more than 45° from horizontal
Safety Training: Technical Training
Tag lines have been identified as ineffective for the application
Bottom of load is no more than chest high above landing area
No risk of being struck by the load if it swings or falls out of control
Hazards identified and precautions taken to prevent tripping and falling under load
Hand and body part hazards for pinch points are evaluated and eliminated or controlled
Employee Guiding a Suspending Load
The pre-job briefing will identify the need for being in the LDZ to guide the load.
Employees can get near a load and assist in guiding the load into place with their hands, provided ALL of the following requirements are met:
Safety Training: Technical Training
Rigging used for support during pre-positioning of machines, piping, platforms, walkways, and steel members, is not to be removed until all leveling and alignments are complete and the item is secured in place.
Inspect rigging after use
Clean work area
Return rigging to storage
What Do I Do When the Rigging Job is Complete?
Safety Training: Technical Training
Any time rigging and lifting of a load is performed, there is the potential for an accident.
Loads can and do fall.
Rigging accidents are never planned, they occur when things are overlooked or safety rules are violated.
No one wants a rigging accident to happen, nor do they want to be involved in one.
This course has been developed to inform you of the TVA Rigging Program requirements in an effort to prevent rigging accidents from occurring.
Always use safety first as a rule, when performing rigging activities.
