Firestop in healthcare

Fire protection and airflow control to help minimize risk in mission-critical facilities

Fire protection and airflow control to help minimize risk in healthcare facilities

Challenging requirements

When it comes to fire safety, hospitals are uniquely challenging projects. On the one hand, variations in the mobility of occupants mean that evacuation times must be maximized. On the other, modern hospitals contain complex and ever-changing building services. This demands passive fire protection and compartmentation measures which help to meet the strictest regulations and can allow critical rooms to remain in full operation after a fire incident. 

Active fire protection - including detection (e.g. alarms) and suppression (e.g. sprinklers) should also be combined with containment which can be achieved with passive fire protection.

Importance of passive fire protection

With dynamic and complex requirements for building services, the number of penetrations passing through fire rated walls and ceilings is typically high. Gaps in fire-rated walls and ceilings may represent a risk for patients, staff and equipment, as fire – and more importantly smoke – can spread rapidly.

Active fire protection alone, including detection (e.g. alarms) and suppression (e.g. sprinklers), may not be enough.

Containment of fire and smoke is also key: effective compartmentation can be achieved with passive fire protection.

Fire can be a common post-earthquake risk, therefore firestop products should be tested under seismic conditions.

Fire safety after a seismic event

Fire can be a common post-earthquake risk, as mechanical pipes and electrical cables can be damaged, releasing flammable contents or sparks. Hospitals are also critical in helping communities recover from earthquakes, so it’s important that they don’t experience significant damage or associated downtime.

Therefore, firestop products used for pipes, cables and joints, should be tested under seismic conditions and designed to withstand movement.

Healthcare is a sector under severe cost pressure, therefore firestop solutions should be easy (and cost-effective) to maintain.

Keeping operating costs low

Healthcare is a sector under severe cost pressure with a duty to keep building life-cycle costs low. Hospitals are dynamic environments with constantly changing patient requirements and technological advancements. As new equipment is purchased and existing equipment is maintained or reconfigured, firestopping after every maintenance activity can be an uncalculated hidden cost.

On top of that, in critical rooms like Intensive Care Units the air pressure should remain stable. Therefore, the prevention of air leakage and every marginal efficiency gain can positively contribute to the reduction of the life-cycle cost of the building.

Firestop solutions that contribute to easier maintenance and airflow control can have a direct impact on your bottom line. 

Sensitive surroundings

As well as the wide-ranging challenges of designing, building and maintaining healthcare facilities, there are also other significant challenges in ongoing operations. When looking to contain the spread of fire and smoke, there are other important considerations – such as infection control, airborne fibers and acoustics.

Airborne bacteria can pass between rooms, if airflow is not properly controlled.

Infection control

Penetrations for services between patient rooms can represent a source of airborne bacteria transmission.

Therefore, airflow control must be carefully managed to help keep the air where it is intended to be and therefore reduce the spread of infection.

Commonly used traditional firestopping methods, like coated boards, are often composed of fibers of metallic ore and igneous rock.

Virtually fiber-free

Commonly used traditional firestopping methods, like coated boards, are often composed of fibers of metallic ore and igneous rock. Whilst they can effectively prevent smoke and fire spreading, repenetrating these systems with pipes or cables may release fibers into the air, which could pose a risk to patients, particularly those in critical environments like operating theatres or intensive care units.

Firestop products with good acoustic properties should be considered to help improve patient privacy, comfort and recuperation.

Noise reduction

Patient privacy, comfort and recuperation may be compromised when noise from adjacent spaces travels uninhibited. A main cause of these problems is the inadequate acoustic insulation between rooms.

Firestop products with superior acoustic insulation properties help contribute to the overall noise reduction.

CAST-IN DEVICE

Firestop cast-in devices make life easier compared to traditional methods of breaking or coring after the concrete is poured. A one-step solution that maintains the opening and firestops the pipes at the same time.

Once installed, the device has an integrated water and smoke seal which impedes infections through standing water, as well as meeting high acoustic requirements.

Code compliant

Our products are designed to meet firestopping requirements of a wide range of international and national codes and approvals, such as UL, ETA, etc.

Many firestop products come with additional benefits, including mold and mildew resistance, thermal or acoustic insulation. Many also meet stringent environmental requirements to support green building standards, such as LEED® and BREEAM®.

On top of that, many of our firestop products have been tested according to the newly developed ASTM E3037 standard, which measures the performance of the products under movement and seismic conditions.

University Hospital in Aalborg, Denmark

The University Hospital is the centerpiece of ambitious plans to centralize all existing regional healthcare facilities under one roof. The challenge was to ensure all firestop is installed correctly, is easy-to-maintain and is future-proofed despite routine cable retrofitting. The solution includes over 5,000 Hilti firestop cast-in collars.
