The new London Supplementary Planning Guidance was recently published (August 2014) with the title "The Control of dust and emissions during construction and demolition". It is a welcome update to the previous planning guidance drawing on recommendations by the Institute of Air Quality Management. However it contains some errors and omissions concerning dust monitoring. Specifically:-
- Appendix 8, Section 5 (Dust assessment) essentially refers to the BS 1747 Part 5 directional dust gauge, which is a withdrawn British Standard and no longer recommended. Directional dust can be assessed using sticky pad directional dust gauges.
- Percentage EAC is not a feasible measure of mass concentration unless particle size, shape, density and colour are known, as well as weather conditions during sampling. Settled dust mass can be determined from both Frisbee and horizontal sticky pad samplers.
Comprehensive guidance on dust monitoring at construction and demolition sites is given in "Guidance on Air Quality Monitoring in the Vicinity of Demolition and Construction Sites" produced by the Institute of Air Quality Monitoring (IAQM) in 2012 - see link below.
DustScan has assisted various working parties in the preparation of guidance that is widely used including those items listed below. Other working parties dealing with specific dust risks are also being assisted including for example a subcommittee concerned with health risks from asbestos in soil.
