Use of synthetic slings in adverse conditions or hazardous applications

1. The material from which synthetic slings are manufactured has selective resistance to chemicals.

The resistance of man-made fibers to chemicals is summarized below:

a) polyester (PES) is resistant to most mineral acids but is damaged by alkalis;

b) polyamides (PA) are virtually immune to the effect of alkalis;

however, they are attacked by mineral acids;

c) polypropylene (PP) is little affected by acids or alkalis and is suitable for applications where the highest resistance to chemicals other than solvents is required.

Solutions of acids or alkalis which are harmless can become sufficiently concentrated by evaporation to cause damage.

Contaminated slings should be taken out of service at once, soaked in cold water, dried naturally, and referred to a competent person for examination.

Slings with grade 8 fittings and multi-leg slings with grade 8 master links should not be used in acidic conditions. Contact with acids or acidic fumes causes hydrogen embrittlement to grade 8 materials.

If exposure to chemicals is likely, the manufacturer or supplier should be consulted.


2. Synthetic slings are suitable for use and storage in the following temperature ranges:

a) polyester and polyamide: -40°C to 100 C,

b) polypropylene: -40 С to 80 °C.

At low temperatures, ice formation will take place if moisture is present. This may act as a cutting agent and an abrasive causing internal damage to the sling. Further, ice will lessen the flexibility of the sling, in extreme cases rendering it unserviceable for use.

These ranges vary in a chemical environment, in which case the advice of the manufacturer or supplier should be sought.

Limited indirect ambient heating, within these ranges, is acceptable for drying.


3. The man-made fibers from which the synthetic sling is produced are susceptible to degradation if exposed to ultraviolet radiation.

Roundslings should not be stored in direct sunlight or sources of ultraviolet radiation.
