Study Notes

Ladder Safety

Set the ladder at a 4:1 ratio: 1 horizontal length for every 4 vertical heights.
Always face the ladder when in use.
Utilize a three-point contact method (one hand and two feet or two hands and one foot) while moving up or down.

Scaffold Systems

Provide secure work platforms.
Two common types:
- Elevating working platforms: height adjustable.
- Framed scaffold systems: fixed height.
Working load limit (WLL) is a crucial safety consideration.

Rope Strength Reduction

Knots, bends, or hitches significantly reduce rope strength:
- New rope: 100% strength.
- Knot: reduced to 50%.
- Bend: reduced to 50%.
- Hitch: reduced to 75%.
- Splices: reduced to 80%.
Normal safety factor for lifting personnel: 10:1; other uses: 5:1.

Nylon Rope Properties

Excellent strength for industrial use (anchor lines, safety ropes).
High elasticity and shock absorption during loading.
Good durability and flexibility.
Resistant to abrasion, organic solvents, and alkalis.
Safe for storage when wet.

Wire Rope Usage

General rigging and hoisting: 5:1 safety factor.
Lifting personnel: 10:1 safety factor.
Public elevators: 20:1 safety factor.
WLL determined by inspecting the sling tag or reference table.
Discard slings showing signs of stretch or significant wear (over 10% link diameter).

Rigging Hardware Inspection

Employers must inspect all rigging equipment before each shift.
Only one plate can be lifted safely with a plate clamp, regardless of type.

U-Bolt and Single Saddle Usage

U section of the clip should be on the short end of the rope; the saddle on the loaded end.
Remember: "never saddle a dead horse" to ensure proper setup.
Use an appropriate thimble size to prevent wear on the rope eye.

Safety Regulations

Employers must meet minimum OHS Code requirements but can exceed those for improved safety.
Workplace Health and Safety advocates for enhanced safety measures.

Double Basket Hitch

Consists of two single-basket hitches.
Balance loads by placing slings under and apart correctly to prevent slipping.
Use shoulder placements on loads to reduce the risk of shifting.

Double Wrap Basket Hitch

Sling wraps completely around the load for better handling.
Ideal for loose materials and cylindrical objects, providing comprehensive contact and stability during lifting.
