6 . Release of the web lashing: Care should be taken to ensure
that the stability of the load is independent of the lashing equipment
and that the release of the web lashing shall not cause the load to
fall off the vehicle, thus endangering the personnel . If necessary
attach lifting equipment for further transport to the load before
releasing the tensioning device in order to prevent accidental falling
and/or tilting of the load . This applies as well when using tensioning
devices which allow controlled removal .
7 . Before starting to unload, you must loosen the lashing until the load
is free .
8 . During loading and unloading attention has to be paid to proximity
of any low overhead power lines .
9 . The materials from which lashing straps are made have selective
resistance to chemical attacks . Seek the advice of the manufacturer
or supplier if exposure to chemicals is anticipated . It should
be noted that the effects of chemicals may increase with rising
temperatures . The resistance of man-made fibres to chemicals is
summarized below .
–
Polyamides are virtually immune to the effects of alkalis . However,
they are attacked by mineral acids .
–
Polyester is resistant to mineral acids but is attacked by alkalis .
–
Polypropylene is little affected by acids and alkalis and is suitable
for applications where high resistance to chemicals (other than
certain organic solvents) is required .
–
Solutions of acids or alkalis which are harmless may become
sufficiently concentrated by evaporation to cause damage . Take
contaminated webbings out of service at once, thoroughly soak
them in cold water, and dry naturally .
