Ductwork
preparation, welding, inspection, testing and storage. One way to guarantee compliance is by using
advanced manufacturing and service levels throughout the project, provided by a company that can supply a turnkey HVAC solution, incorporating numerous review and validation procedures alongside a programme of performance analysis. During the manufacturing processes alone, detailed records should be produced, which includes raw material traceability, weld mapping, inspection records, testing and completions. In addition, companies should also expect reports on feasibility, concept, design, safety processes, computer models, manufacture and installation. Moreover, any company designing, manufacturing or installing ductwork into a hazardous or sensitive environment needs to have a previous track record of quality, including a detailed understanding of the safety requirements, not to mention, the importance of ventilation systems as a factor in containing and controlling potentially harmful chemicals or fumes. Having highly trained, skilled, competent and experienced staff, who understand the specific project requirements, national codes, standards and specifications in both the manufacture and installation processes for each environment will assist in this process. In all major projects, named senior staff should be assigned and, in some specialist cases, a team of engineers may be on site managing the needs of the project. More often than not, there is the need for a ductwork system to manage the spread of fire. There are many specialist ranges of fire resistant ductwork designed, manufactured and engineered to meet the need for the safe removal of smoke and other products of combustion, minimising the risk of a fire becoming widespread across a building. CE Marking for all construction products covered by a harmonised European standard or conforming to a European Technical Assessment became mandatory on 1 July 2013 through the Construction Product regulations (CPR). For Smoke Control Ductwork, CE Marking became mandatory on 1 July 2014. To ensure a ductwork system can handle fire
conditions, two units from the same solution must be tested both vertically and horizontally under BS EN 1366-1:2014. Tests must also be carried out on a third piece of ductwork under BS EN 1366-8:2004, which provides protection against the spread of smoke and fire to different sections of a building. Providing the results of these stringent tests to customers is the only way to guarantee the safety of fire systems ductwork. It is critical that all those involved in the design,
procurement and installation of fire resistant Ductwork systems must be aware of requirements of the CPR and specify and procure products which are CE marked. Hargreaves has CE marked all its products in line with the company’s ISO 9001 quality systems, which ensures traceability of fabrication and materials to underpin CE marking. Hargreaves Fire Systems offers full compliance There is a significant level of safety and compliance
required to ensure ventilation and ductwork systems are of the highest quality across all projects. When specifying a HVAC solution, particularly in hazardous or sensitive environments, it is vital to use a company that can guarantee all standards are met through every stage of the process. Hargreaves Ductwork provides bespoke HVAC solutions, high integrity ventilation systems from concept design and fabrication through to installa- tion and commission.
