|
|
|

|
|
How many digits is the ID number for life safety rope?
|
8 digits (2-diameter, 4-month/year, 2-sequence #)
|
|
|
What are the breaking strengths of the 6, 8, 9, 11.1, and 13mm rope?
|
6mm=9.7kN, 8mm=14kN, 9mm=16kN, 11.1mm=27kN, 13mm=46kN (Note that breaking strengths will vary dependent on manufacturer, age of the rope, humidity and temperature)
|
|
|
Should rope ever be coiled?
|
No, coiling of ropes should be avoided. When the rope is coiled, there is a tendency to form loops that will remain in the rope, which will prematurely wear or damage the rope.
|
|
|
How should rope be cleaned?
|
This is accomplished with running clear water and a brush. The rope is flushed with the water as the brush removes the dirt. If a rope is badly soiled it can be washed in a regular manner, and then placed into a front loading washing machine for cleaning. The machine is placed on a gentle cycle and mild soap is used in the wash cycle. It is best to place the rope in a large mesh bag or daisy chain the rope into large loose coils to protect it from mechanical damage.
|
|
|
What is the proper method to cut rope?
|
With a commercial electric hot knife
|
|
|

Incident location, or incident number 8. Inspection date, Inspectors name and initials 9. Rope condition and comments 10. Date of washing, type of washing 11. Date of retirement, Retirement level 12. Rope Identification number

|
What is rope aging?
|
Aging refers to the natural processes that affect the deterioration of the macromolecular structure of a rope. Aging occurs even if never used. The biggest factor of aging is use.

|
1. DO NOT STEP ON THE ROPE. 2. Protect the rope at abrasion points. 3. Do not overload a rope. 4. NEVER TOW A VEHICLE with a life safety rope. 5. Do not over bend a rope – strive to maintain a bend radius of 4 times the rope diameter. 6. Do not leave knots tied in a stored rope (unless they are left loosely tied). 7. Store ropes using appropriate methods. 8. Protect a rope from falling objects. 9. Protect the rope from sources of high heat.
