BS 6164 deals with the safety of those engaged in the tunnelling process and of those who could be affected by it.
Everyone involved in tunnelling projects.
BS 6164 makes recommendations for and gives guidance on health and safety practices in shaft sinking and tunnel construction.
BS 6164 includes health and safety recommendations that are also relevant to cut-and-cover tunnelling, immersed tube tunnels and other forms of underground construction as well as to the maintenance, renovation and repair of shafts and tunnels.
NOTE: The recommendations is this standard are not intended to apply to the construction of shafts or tunnels for the purpose of mineral extraction.
This British Standard replaces BS 6164:2011, which is withdrawn. The revision takes into account the advances in technology and equipment available to the tunnelling industry as well as new techniques and the effect of changes in legislation and guidance relating to health and safety and environmental matters.
NOTE: There is an error in Table 8 of BS 6164:2019, in which the exposure limits for sulfur dioxide have been incorrectly stated. Whilst this information was correct at the time the standard was published, it has since been updated. The correct limits are 0.5 ppm long term limit and 1.0 ppm short term limit. The information in clause 15.6.3.6 remains correct. It is important that you take note of this update in the application of this standard going forward.
