Treatment and certification

Do flags and banners need a fire certificate?

Stadiums, venues, event organisers and fire-risk assessors may request flags and banners to be treated and certificated to either BS 5852 Part 1 or BS 5867 Part 2 Type B.

Large black and white textile flag drying outdoors after fire-retardant treatment
A genuine project: a large absorbent textile flag drying after specialist treatment.

The direct answer: absorbent textile flags and banners can be professionally fire-retardant treated and supplied with a certificate to BS 5852 Part 1 or BS 5867 Part 2 Type B, depending on which standard the stadium or venue requests.

Which standard applies to flags and banners?

The standard requested depends on the venue and how the material will be used.

BS 5852 Part 1

One of the standards that may be requested by stadiums and venues for flags and banners.

BS 5867 Part 2 Type B

Another standard commonly requested for textile flags, banners and hanging fabrics.

The requested standard should be confirmed before treatment so the correct treatment and certification can be provided.

Which flags and banners can be treated?

Cotton, polyester and other absorbent textile flags and banners can be treated.

The material must absorb the fire-retardant solution. The following cannot be treated:

  • Vinyl banners
  • PVC banner material
  • Laminated banners
  • Waterproof or heavily coated materials
  • Other non-absorbent constructions

What about printed flags and banners?

Printed textile flags can be treated when the printed finish remains absorbent.

Some printing, waterproofing and protective coatings form a barrier over the fabric. These prevent the fire-retardant solution from penetrating the material.

How polyester flag material behaves before and after treatment

These short comparative demonstrations show the difference observed when flame is applied to untreated polyester flag material and to polyester flag material after specialist fire-retardant treatment.

Before treatment

Untreated polyester flag

The untreated material ignites and continues to burn during this short in-house demonstration.

After treatment

Treated polyester flag

After specialist treatment, the material does not sustain flaming or produce burning droplets in this demonstration.

What these videos show: They are practical in-house comparative demonstrations of material behaviour. They are not accredited laboratory tests, do not assign a formal fire classification and do not replace the Certificate of Fire Retardant Treatment issued for identified treated items.

Can outdoor flags receive water-resistant treatment?

Yes. Absorbent outdoor textile flags and banners can receive a specialist water-resistant fire-retardant treatment designed for exposure to the weather.

The outdoor treatment is also used for absorbent tent and marquee fabrics. It provides greater resistance to moisture than the standard indoor treatment.

The outdoor treatment can make fabric stiffer

This is most relevant where the movement, drape or close-up appearance of the flag is important.

Outdoor treatment does not make vinyl, PVC or an already waterproof banner absorbent.

85,000 flags treated for an NFL game at Wembley

Fire Proofing Ltd was asked to treat 85,000 polyester flags for an NFL game at Wembley Stadium.

A representative flag was treated first and returned for approval before the full project began.

With a short lead time, space provided at the venue and additional labour supplied by the event team, all 85,000 flags were treated over four days.

This large-scale project demonstrates our experience in planning treatment, handling substantial quantities and working to fixed event deadlines.

What does the certificate confirm?

After treatment and payment, a Certificate of Fire Retardant Treatment is supplied for the standard requested by the stadium or venue.

The certificate identifies the flags or banners covered by the work and confirms treatment to either:

  • BS 5852 Part 1
  • BS 5867 Part 2 Type B

It can be retained with the event or venue’s fire-safety records and supplied to the organiser, venue manager, fire-risk assessor or insurer.
