Materials producers expressed fears this week that the Construction (Design and Management) 2007 regulations guidance discriminates against them by putting them on a danger list.
The Designers' Guidance - produced by the industry and vetted by 10 relevant professional organisations plus the Health & Safety Executive (HSE) - lists products and practices 'that should not be specified or result from the design (without good reason).'The Quarry Products Association (QPA) and the British Precast Concrete Federation (BPCF) are appealing to the HSE, concerned that their members will be adversely affected by new guidance on the use of retarded mortar mixes for blockwork walls. Both argue that retarded mortar mixes will always cause temporary instability - the retarder lengthens curing time - but they say this should not be deemed unsafe as the instability is understood and taken into account during construction. A spokesman at QPA said, 'We are united in our concern at the misleading nature of the statement within the Designers' Guidance. Neither the QPA nor the BPCF were consulted before this aspect of the guidance. As we have a close working relationship with the Health & Safety Executive, we will be discussing the matter further in the coming days.'
