A statement on the NASC's stance on the use of impact wrenches during erection/dismantling and alterations to scaffolding.
Further to a previous statement made by the NASC in 2012, the confederation has received an increasing number of enquiries regarding its stance on the use of impact wrenches during erection/dismantling and alterations to scaffolding.
In order to provide clarity and advice for members and other users of impact wrenches, the NASC has recently completed some testing. A wide range of drop forged couplers from different suppliers in various conditions (new, used, lubricated and unlubricated) were tightened using two popular types of impact wrenches as well as a traditional scaffolding spanner. In excess of 60 tests were completed.
The subsequent results data indicated that there were no concerns or adverse effects in respect of any of the tests carried out (for both impact wrenches and traditional scaffold spanner). It is therefore the view of the confederation that the use of impact wrenches during erection/dismantling and alterations to scaffolding is acceptable. However, there are several important recommendations which should be considered by the employer prior to authorising the use of impact wrenches by employees:
The NASC has developed a basic Tool Box Talk which members and other users of impact wrenches may find useful.
The NASC will continue to monitor the situation and will issue further information if required.
We can send you an NASC Information Pack in the post.
