Learning outcomes Today we will cover… • • Why smoke control is important • Overview of Smoke Control Dampers (compared to fire dampers) • Smoke Control Damper classifications • Look at strategies and best practice

Key fire and smoke terminology Compartmentation is… • • Keeping the fire and smoke limited to one part of a building Cause and effect is… • • Which dampers open • Which dampers close • Some of these dampers will be fire dampers, some smoke dampers • Details hot/cold smoke extraction • The wider cause and effect may include AOVs, fans and fire doors

Why Smoke Control? Our industry understands better than most that it is not the fire that kills, but smoke. • Grenfell Tower - shock waves through the building services industry. • Under the radar … until disaster

… Smoke is the #1 Killer in UK Fires. 20% Overcome by gas or smoke 38% Burns 16% Burns and overcome by gas or smoke Other/Unspecified 25% Table Source: Home Office Incident Recording System / https://www.gov.uk/government/collections/fire-statistics Contact: FireStatistics@homeoffice.gsi.gov.uk

The drive towards compliance…. Product Standard BS EN12101-8 • Classification Standard BS EN13501-4 • Test Standard BS EN1366-10 • • First published April 2011 • Widely used in Europe for smoke control • UK had previously favoured fail-safe closed actuators, part 10 uses drive open/drive closed. • Post-Grenfell fire, industry re-focusing on standards and applications.

Fire Dampers (MSFD or FD) Fire damper function is to maintain compartmentation Fire dampers to be CE marked to BS EN 15650 • Tested to BS EN 1366-2 • Classified to BS EN 13501-3 • Fire Dampers ✓ have thermal release mechanism at 72*C ✓ fail safe-close ✓ have fire resistance in closed position ✓ have known leakage characteristics (determining classification ‘E’ or ‘ES’)

Smoke Control Dampers (MSD) Smoke control damper function is to contain/maintain an extraction path for smoke. The CE marked to BS EN 12101-8 • Tested to BS EN 1366-2 and BS EN1366-10 • Classified to BS EN 13501-4 • Smoke control dampers: ✓ Drive to open or closed position < 60 seconds ✓ Maintain their position – non-fail safe ✓ Have known leakage characteristics ✓ Maintain free area in open position at standard or elevated temperatures

Typical Application Extract fan Basement levels Multi compartment Single compartment Multi compartment Fire resistant walls Closed Open

Typical classification E90(v ew i↔o )S1000C 10000 AAmulti E90 = “integrity” fulfilled 90 minutes • v ew = installation in/on the duct running through vertical supporting • construction i↔o = i – fire from inner to outer side, o – fire from outer to inner side • S = tightnes against smoke spread – penetration < 200 m3/(hm2) • 1000 = test by 1000 Pa pressure differential • C10 000 = 10 000 cycles test open – close before fire test • AA = automatic activation • Multi = multi compartment usage •

Hot 400/30 The test to achieve this part of the classification involves cycling the damper whilst the damper is under elevated temperature The test is 60 minutes long • The damper is cycled every 150 seconds for the first 30 minutes • rising from ambient to 400 degrees within 7 minutes. After 30 minutes the damper is to remains open for the duration • of the test and the time temperature curve goes back to the standard time temperature curve. (38 minutes - 877°C, ending at 60 minutes - 945°C) Passing only the Hot400/30 test does NOT mean a damper is • 1366-10

AA / MA Typically we use AA dampers in the UK for cold smoke clearance… • AA Smoke control system with automatic activation smoke control system (smoke and heat exhaust ventilation type or pressure differential type), that operates automatically on receipt of a smoke or fire alarm without any manual action/intervention NOTE systems with an attended control room classed as an automatic system . • MA Smoke control system with manual intervention smoke control system (smoke and heat exhaust ventilation type or pressurization type), that will be put into manual operation, on detection smoke or fire. This is instigated with human intervention leading to a sequence of automatic actions. For most applications, we recommend using an AA system with • dedicated damper control panel
