In your role as an expert fire consultant, or as an internal consultant at a construction company, there are four important factors you need to know, and which most importantly you should follow if you and the company are to abide by the law.

  1. Fire-impregnated wood product covered by the mandatory requirements for CE certification.
  2.  Fire-treated wood products are subject to the mandatory requirements of the Declaration of Performance (DoP).  
  3. The manufacturer is subject to the requirement of, similarly to the type approval certificate requirements for third-party inspections of manufacturing, providing proof of continuous quality control, in accordance with the Planning and Building Act (SFS 2010:900). 
  4. Each individual wood species is covered by the mandatory requirements to be certified and under which certification actually refers to the correct standard, for example, harmonized product standards. 

Woodsafe are authorized manufacturers     

Our services have been approved since 2008 and since 2009, as the first manufacturer in Northern Europe, our services are also CE certified in accordance with harmonized product standards EN14915 and EN13986. Our quality system is ensured according to the appendix Appendix ZA, system 1. Our knowledge of fire-treated wood is our strength, which gives you as an expert consultant/fire safety consultant security in your work and choice of regulatory product. Our quality- and management system is certified according to ISO 9001, issued by the SP.

Why certification and third-party control?

When it comes to authorization, we believe that you as an expert fire consultant have a responsibility to prescribe and/or refer to manufacturers with authorization to place fire-treated wood on the market. Authorization means that the manufacturer's service and quality system is certified and is under third-party control. Manufacturers who are not subject to third-party monitoring and products that are not certified, i.e. are only fire tested and classified, are not the same as authorized manufacturers. It is of the utmost importance that you in your role as an expert consultant understand how important it is that the result of a fire or classification report cannot, and must not constitute approval for use in permanent structures.   

Type approval certificates are no longer a requirement of BBR, but quality assurance is in accordance with the Planning and Building Act, which effectively excludes any system that does not follow the production control system, for instance third-party production monitoring of notified bodies such as the SP Technical Research Institute of Sweden (No.Body 0402).  

How do you know if the documents are correct 

In addition to these four mandatory requirements, you as an expert consultant in your professional role should have sufficient knowledge to distinguish any documents that are not certifying documents. There is an extensive problem with incorrect documentation, e.g. fire testing and classification reports, documents drawn by other institutes carrying the title certificate but which in practice are not certifying certificates under the Planning and Building Act or the EU Construction Product Regulation etc. There are examples where institutions issue certificates for a product or a manufacturer generally describing the product as certified B-s1,d0. But in fact this is not the correct certification in accordance with the requirements of Annex ZA and the Construction Products Regulation 305/2011. The document carries the title certificate but no more than that, at least not if one is to adhere to the requirements of the Construction Products Regulation.

Reading the documentation is not always easy.  

Some advice to you as an expert fire consultant is not to worry, for example B-s1,d0. There are other factors that are equally important, for example 
    •   For example, is B-s1,d0 with or without air gaps, met?                
      - In many cases, B-s1,d0 without air gaps gives B-s2,d0 with air gaps. 
    •  Is the wood species in question certified?  
       - Certified spruce cannot replace the use of other types of wood,                     for example pine.
    •  What is the wood species' thinnest approved thickness for B-s1,d0? 
        - Approved at 25mm does mean approved at for example 15mm. 

Other factors affecting performance, which must be clear from the certificate, are:
    •  For example, is B-s1,d0 met, even if the spruce panel is painted? 
    •   Is B-s1,d0 met, even if the panel is mounted as furring, giving           4-side exposure.  
    •   Is B-s1,d0 met if the plywood sheet is perforated? 
       - Smooth plywood B-s1,d0 does not mean that perforated plywood has B-s1,d0.   

Comparing fire treatment to fire retardant painting

We will not go into detail on the difference, however, there are some factors you must take into account and ensure. These include:

    •   Furring must have fire retardant paint on all four sides in order to             meet the requirements for such an assembly that is common in ceilings and walls, e.g. sports halls, corridors, etc.  
    •  Perforated plywood must have fire retardant paint on the front and back and in each perforated hole in order to meet the requirements for when perforated plywood is used. 
    •   Onsite assembly is manual and is regarded as uncontrolled in relation to Industrial products. 

Woodsafe recommend that self-monitoring is documented in accordance with the borehole principle developed by the Nordic Association for Fire retardant treated wood ( Instructions for checking the workplace as recommended by SP/NBT
