Welcome to the Firestop Seminar

Firestop Products: Agenda for this Presentation The need for Compartmentation The Legal & Guidance framework for Firestop products. How fire and smoke spread. Testing & How Firestop Products Work Third Party Accreditation: Products & Installers The right stuff Myths of the Industry The wrong stuff Getting it right & reducing your liability.

What is Firestopping? Compartmentation Fire walls Fire Floors

Fire Rated Wall or Floor Compartmentation-breaches Fire Rated Wall or Floor

Legislation, Regulations & Codes of Practice Building Regulations /Building Standards(Scotland) Approved Document B / Technical Handbooks Fire (Scotland) Act 2005 -Fire Safety (Scotland) regulations 2006 CDM 2007 LPC (Loss Prevention Council) ‘Code of Practice for the Construction of Buildings’ Joint Code of Practice on Fire Prevention on Construction Sites IEE 16th Regulations Firecode, HTM 81, 83, 85, 86 for hospitals Different documents – same message Compartmentation as early as possible and maintained for life of building Fire, insulation, smoke Firestopping 3rd party certification of product and installation

Approved Document B Proprietary fire-stopping and sealing systems, (including those designed for service penetrations) which have been shown by test to maintain the fire resistance of the wall or other element, are available and may be used. Other fire-stopping materials include: • cement mortar, • gypsum based plaster, • cement or gypsum based vermiculite/perlite mixes, • glass fibre, crushed rock, blast furnace slag or ceramic based products (with or without resin binders), and • intumescent mastics. These may be used in situations appropriate to the particular material. Not all of them will be suitable in every situation. 8

Risk Assessment Guidance The government has published a series of guidance documents There are separate guides for the following premises: large places of assembly small and medium places of assembly factories and warehouses residential care sleeping accommodation theatres and cinemas educational premises offices and shops outdoor events hospital premises transport network

Fire Risk Assessment Responsibility Under current UK fire safety legislation, the 'responsible person-duty holder' - that is the owner, manager or employer - must carry out a fire safety risk assessment and implement and maintain a fire safety management plan. The 'responsible person' can potentially face fines and imprisonment if something goes tragically wrong. Several high profile companies and organisations have been fined heavily after getting their fire risk assessments wrong. 10

Fire Spread Heated air rises Radiation Convection Conduction

Firestop products are tested on the following criteria: Test Measurements Firestop products are tested on the following criteria: Heat Heat Flames Gases Gases Flames Insulation Measures the ability of an element to insulate, i.e. time taken for the non fire side to reach180° Integrity: Measures the ability of a product to prevent gas and flame to pass through in a fire Fire test determined more than just a fire testing. The three properties shown are all assessed in a fire test. What is commonly forgotten is that insulation is an important factor to be considered . The technical standard in Scotland have insulation for a requirement for building elements and therefore the it can be seen that the firestopping must similarly be complying. Both criteria are measured in hours and minutes.

3rd Party Accreditation PRODUCTS ADB 0.20 “Third party accredited product conformity certification schemes not only provide a means of identifying …. products…. which have demonstrated that they have the requisite performance in fire, but additionally provide confidence that the ... products .. actually supplied are provided to the same specification or design as that tested/assessed” RRO Guidance – Section 8 “Third-party certification schemes for fire protection products and related services are an effective means of providing the fullest possible assurances, offering a level of quality, reliability and safety that non-certificated products may lack.” Essential Principles Document “Principle 10: As a minimum, all fire protection products shall be third party certified to an appropriate product or performance based standard” 14

3rd Party Accreditation INSTALLERS ADB 0.20 “Third party accreditation .. of installers of .. provide a means of ensuring that installations have been conducted by knowledgeable contractors to appropriate standards, thereby increasing reliability of the anticipated performance in fire.” 15

Examples of Firestop Products

CP 670 Installation All exposed mineral wool surfaces must be ‘buttered’ with mastic 17

Firestop Mortar Installation NB Pipe insulation has to be removed prior to pour or fit CP 645 Firesleeves to replace insulation 18

2nd Fix After all cables and sockets in wall sealed up and sockets on other wall put in. Putty pads put to inside of backbox. International Firestop Training 19

Firestop Cushions 21

Firestop Bricks 22

Firestop Expanding Sealant 23

Firestop Foams Firestop foams are unsuitable for general firestopping solutions.

Examples of poor Firestopping

Fire collar not fixed properly. It will fall off in a fire. Wrong size of fire collar.

Considerations for NHS premises wishing to minimise their firestop liabilities? Identify any firestopping issues through the risk assessment procedure. Appoint contractors who understand and have been trained to install firestop products correctly – consider Accredited Contractors. Will contractors supply a written log of each application and the products used in each application? 29
