Cable ties are used in a large number of applications. Zip ties that are used in FME jobs must be unique since they have a high likelihood of becoming foreign material themselves.
First, they need to be colored or tinted to aid in their visibility. They should also be free of any metal fastening devices. Metal barbs can become more damaging foreign material than the softer materials that the cable tie is made out of. Ties for use in FME should also be low in potentially harmful chemicals such as halogens and heavy metals. In some cases where work is being done over water, zip ties should have the capability of floating.
Some solutions that fit these criteria include:
Nylon cable ties
The traditional form of tie wrap, tinted nylon ties provide a long lasting durable option, however, they do not float.
Nylon Floating Zip Ties
A patented invention: These are nylon cable ties with an attached floatation device.
Natural floaters
A cheaper alternative to the Nylon floating cable ties: These are made of a less dense, low halogen, plastic material that floats. Due to their decreased density these tie wraps are weaker than the nylon floaters.
Velcro ties
Several styles of Velcro ties allow for an alternative to the typical nylon cable tie style. These ties are gentler on the materials they tie.
Tefzel
These are non floating zip ties that are designed to be resistant to radiation and other harsh external stresses.
Cable ties usually have to be purchased in large quantities, so use your judgment as to the level of FME protection that is required for any particular job. Don’t try to save a few pennies now only to find out that an extra dollar could have saved you thousands.
