What advice does the SCA have for AOV – Smoke Vent testing?

Maintenance of smoke ventilation systems (including AOVs) should only be undertaken by competent organisations that are both members of the SCA and accredited to IFC Certification Ltd's third party competence scheme. The SCA recommends you engage with an SCA member to provide access to competent engineers and knowledge to help you service any smoke vent systems that you may inherit in your property portfolio.
