Rigging, Lifting & Fall/Ladder Safety

Common Tasks, Genuine Hazards

Rigging, lifting, ladder use, and elevated work are some of the most common physical tasks an Auxiliary Operator performs — and also among the most common sources of serious injury across all of industry, not just power plants. This module extends the fall protection concept briefly introduced in BTA-103 into the full set of practical skills and precautions involved.

Rigging Basics

Rigging is the practice of using slings, hardware, and lifting equipment to safely attach a load to a crane or hoist. Slings come in several types — wire rope, chain, and synthetic (nylon/polyester webbing) — each suited to different load types and environments, each with a rated capacity that must never be exceeded and that decreases depending on the angle and configuration used. Rigging hardware — shackles, hooks, eye bolts — connects slings to the load and to the crane hook, and like slings, each piece has a rated working load limit.

Load Weight and Center of Gravity

Before any lift, the actual weight of the load must be known (or conservatively estimated) and compared against the rated capacity of every piece of equipment in the lift path — sling, hardware, and crane/hoist itself. Equally important is understanding the load's center of gravity: rigging attached off-center can cause a load to tip, swing unpredictably, or place uneven stress on the rigging the moment it's lifted clear of its support.

Signals and Communication

Crane and hoist operations use standardized hand signals (and increasingly radio communication) between the rigger/signal person and the equipment operator. Clear, unambiguous signals — the same principle as the radio communication standards from BTA-102 — prevent the kind of miscommunication that can cause a load to move unexpectedly while people are near it.

Pinch Points and Hand Safety

Rigging work inherently involves hands near heavy hardware, tensioned slings, and moving loads. Keeping hands clear of pinch points — anywhere two surfaces can close together, whether it's a shackle pin, a load settling onto blocking, or a sling tightening — is a constant, deliberate habit, not something to rely on quick reflexes for.

Taglines and Load Control

A tagline is a rope attached to a load, allowing personnel to guide and steady it from a safe distance during a lift, rather than pushing or guiding the load directly by hand. Using a tagline correctly keeps hands away from the load itself while still providing the control needed to prevent it from swinging into equipment, structures, or people.

Ladder Safety

Maintain three points of contact (two hands and one foot, or two feet and one hand) at all times while on a ladder. For extension ladders, the base should be positioned so the horizontal distance from the wall is roughly one-quarter of the ladder's working height (a 4-to-1 ratio) — too shallow an angle risks the base sliding out; too steep risks tipping backward. Never carry tools or materials in your hands while climbing — use a tool belt or have them raised/lowered separately.

Fall Protection Harnesses

Building on BTA-103's introduction, a properly fitted harness connects to an anchor point rated for fall arrest forces (typically 5,000 lbs per person, per OSHA standard) via a lanyard or self-retracting lifeline. The anchor point matters as much as the harness itself — an improperly rated or positioned anchor point can fail exactly when it's needed most, or allow enough fall distance that the person strikes a lower level before the system arrests the fall.

Scaffold Safety

Scaffolding must be erected, inspected, and tagged by qualified personnel before use — never modify or move scaffolding yourself. Guardrails, proper decking (fully planked, no gaps), and secure access (ladders or stair towers, not climbing the frame) are all requirements, not suggestions. A scaffold tag indicating it's safe for use should be checked before every use, not assumed to still be valid from the last time you used it.

Pre-Use Inspection: The Constant Thread

Every piece of equipment covered in this module — slings, hardware, ladders, harnesses, scaffolding — requires a pre-use inspection every single time, not just periodically. Damaged, worn, or out-of-date equipment (many items have inspection tags with expiration dates) should never be used, regardless of how routine the task seems or how much time inspection seems to cost.
