Where asbestos gaskets, ropes and textiles are found

Asbestos was widely used where flexible heat-resistant sealing, insulation or fire protection was required.

Common examples include:

  • compressed asbestos fibre gaskets;
  • pipe and valve flange gaskets;
  • boiler gaskets;
  • vessel gaskets;
  • rope seals around oven and boiler doors;
  • rope packing around frames and penetrations;
  • asbestos string used on threaded pipe joints;
  • heat-resistant tape;
  • woven asbestos cloth;
  • asbestos yarns;
  • fire blankets and curtains;
  • textile insulation around older plant.

HSE identifies asbestos gaskets in industrial pipe and valve joints, older boilers and heating appliances, while rope seals and textile products were commonly used for heat and fire protection.

ASM gasket pricing

How much does asbestos gasket removal cost?

Where several suitable CAF gaskets can be removed during the same planned visit, ASM pricing starts from £60 + VAT per gasket.

Multiple gasket projects
From £60 + VAT per gasket

The entry rate applies where multiple accessible gaskets can be removed during the same mobilisation and each item can be dealt with using an appropriate controlled low-risk method.

Final pricing is confirmed from the actual number, location, condition and plant requirements.

When £60 per gasket may not apply

A higher project cost may apply where:

  • only one gasket is being removed;
  • plant must be dismantled to reach the gasket;
  • flanges are seized or heavily corroded;
  • the gasket is badly deteriorated;
  • substantial scraping or residue removal is required;
  • the gasket cannot be removed virtually intact;
  • several separate plant rooms are involved;
  • specialist access is required;
  • mechanical or electrical isolation is required;
  • work must take place during a shutdown or out of hours.

Asbestos rope, cloth, yarn and wider textile projects are priced individually.

Compressed asbestos fibre gaskets

CAF gasket removal can often be lower-risk work

HSE's current Asbestos Essentials guidance specifically covers removal of compressed asbestos fibre gaskets from pipework, vessels, plant, heaters and boilers as non-licensed work where they can be removed without substantial break-up.

Typical locations include:

  • pipe flanges;
  • valve connections;
  • heat exchangers;
  • boiler sections;
  • industrial vessels;
  • pump connections;
  • older heating appliances.

Condition matters. A sound gasket that can be eased away virtually intact presents a different job from one that has deteriorated, adhered strongly to the flange or breaks into fragments.

Rope seals & packing

Asbestos rope seals in boilers, ovens and plant

Rope and textile products were widely used where a flexible, heat-resistant seal was required.

They can be encountered around:

  • boiler doors;
  • oven doors;
  • furnaces;
  • heating appliances;
  • vessel lids;
  • service-riser frames;
  • pipework;
  • equipment access panels.

Where a rope seal can be removed using a controlled method without substantial deterioration, HSE treats this as a lower-risk non-licensed asbestos task.

If the rope is brittle, heavily adhered or likely to disintegrate, the work category and controls need to be reassessed.

Work classification

When is gasket or rope removal non-licensed or NNLW?

The important test is not simply whether the product contains asbestos; it is the material condition and the amount of deterioration expected during the task.

Material / task Typical HSE position ASM approach
CAF gasket removed virtually intact Lower-risk non-licensed work. Controlled non-licensed removal by appropriately trained asbestos personnel.
Rope seal removed without substantial break-up Lower-risk non-licensed work. Controlled removal with suitable asbestos controls.
Gasket substantially breaks up during removal HSE identifies this as NNLW. Work assessed and NNLW requirements applied.
Rope seal substantially deteriorates Becomes NNLW where substantial break-up occurs. Notification and NNLW arrangements applied as required.
Routine work on rope, yarn or woven cloth Can fall within non-licensed work where risk remains low. Material and activity assessed before work starts.
Large, deteriorated or insulation-type textile Requires individual assessment against the actual asbestos insulation and exposure risk. Higher-risk control or licensed route used where the assessment requires it.

Do not assume a degraded gasket is still a simple £60 item

The multiple-gasket entry price is based on suitable items capable of controlled removal. If the material has become brittle, bonded to the flange or must be substantially broken up, additional asbestos controls and NNLW requirements can apply.

What ASM assesses on gasket and rope projects

Good photographs and plant information can often allow multiple gasket projects to be scoped efficiently before attendance.

Number of gaskets Multiple items in one location provide the best opportunity for the £60-per-gasket entry rate.
Gasket condition Intact compressed material is different from brittle, delaminating or heavily damaged gaskets.
Flange condition Corrosion and seized components can increase both engineering work and asbestos-removal time.
Residue Old gasket material adhered to the flange may require additional controlled residue removal.
Isolation Pipework, vessels and equipment must be made safe before dismantling and gasket access.
Temperature Hot plant must be safely shut down and cooled before asbestos work begins.
Access Ground-level valves are very different from high-level pipework or restricted plant-room locations.
Work areas Ten gaskets in one plant room can be considerably more efficient than ten gaskets spread across several buildings.
Rope condition Rope seals that remain coherent require different controls from friable material already shedding fibres.
Textile function Heat insulation, fire protection and simple sealing products can require different assessments.
Replacement gasket Clarify whether ASM is removing the ACM only or whether other contractors are replacing and recommissioning the joint.
Shutdown programme Industrial shutdown windows and out-of-hours working can affect project cost.
HSE Asbestos Essentials A25

High-level gasket and rope removal methodology

HSE provides a specific Asbestos Essentials task sheet for removing CAF gaskets and asbestos rope seals. ASM RAMS are based on the actual equipment, ACM condition and project risk assessment.

1
Make the plant safe

Confirm appropriate shutdown, isolation, cooling and safe access before disturbing the joint or equipment.

2
Prepare the area

Restrict access and protect surrounding surfaces and vulnerable equipment from asbestos contamination.

3
Controlled removal

Dampen the asbestos appropriately and carefully ease the gasket or rope away while minimising breakage and abrasion.

4
Residue & cleaning

Deal with adhering residues under appropriate control, clean the equipment and work area, and package asbestos waste correctly.

The aim is controlled removal — not aggressive dry scraping

A gasket that will not release easily can require more time and a different control approach. The objective is to minimise asbestos fibre release rather than force the item off simply to maintain a headline unit rate.

Beyond gaskets

Asbestos rope, yarn, cloth and textile products

HSG264 records asbestos textiles as having been manufactured for primary heat protection and fire-protection applications.

Rope seals Used around boilers, ovens, doors, lids and other heated plant.
Yarn & string Used for sealing joints and threaded pipe connections.
Woven cloth Used around pipework and equipment requiring heat protection.
Asbestos tape Historically used as flexible heat-resistant insulation.
Fire blankets Older heat and fire protection textiles can contain asbestos.
Fire curtains Large textile products require separate assessment of condition, quantity and removal risk.

Rope and textile work is priced separately from the £60 gasket rate

The £60 + VAT starting rate is specifically intended for multiple suitable gasket-removal items. Rope seals, woven textile, fire protection and insulation products are quoted according to their quantity, condition, location and required work category.

Where the unit rate works best

Multiple gasket removal during plant shutdowns

The strongest commercial use for the per-gasket rate is planned industrial maintenance where several known asbestos-containing gaskets can be dealt with during the same shutdown.

Frequently asked questions

Asbestos gasket and rope removal FAQs

How much does asbestos gasket removal cost?
ASM pricing starts from £60 + VAT per gasket where multiple suitable gaskets can be removed during the same planned visit or project. Single items, difficult plant access, damaged gaskets and more complex projects are quoted individually.
Does the £60 price apply to one gasket?
The £60 + VAT rate is intended for multiple-gasket projects where mobilisation and site setup can be shared between several items. Single-gasket work is priced according to location, travel, access, isolation and the actual removal requirements.
Is asbestos gasket removal licensed work?
Not normally where a CAF gasket can be removed virtually intact without substantial break-up. HSE specifically treats this type of activity as lower-risk non-licensed asbestos work.
When does gasket removal become NNLW?
HSE states that if a gasket or rope seal is substantially broken up or damaged during removal, the work becomes notifiable non-licensed work.
Can asbestos rope seals be removed as non-licensed work?
Yes, suitable lower-risk removal of asbestos rope seals can be non-licensed where the material can be dealt with without substantial break-up and the risk assessment supports the method.
Where are asbestos gaskets normally found?
They are commonly associated with pipe and valve joints, boilers, vessels, industrial plant, pumps, heating appliances and older mechanical equipment.
Where are asbestos rope seals found?
Rope seals can be found around boilers, ovens, furnaces, heating appliances, doors, lids, pipework and other equipment requiring a flexible heat-resistant seal.
What if the gasket is stuck to the flange?
Adhering gasket residues can increase removal time and asbestos fibre release potential. The work is therefore assessed according to how much controlled residue removal is likely to be required rather than applying the simple multiple-item rate automatically.
Does the pipe or plant need to be isolated?
Yes. The relevant pipework, vessel, electrical system or plant must be made safe before equipment is dismantled and the asbestos gasket or seal is accessed.
Can ASM remove gaskets during industrial shutdowns?
Yes. Multiple-gasket programmes work particularly well during planned plant shutdowns where locations, isolations and replacement works can be coordinated in advance.
Are asbestos ropes and textiles also £60 each?
No. The £60 + VAT starting price applies specifically to suitable multiple-gasket projects. Rope, yarn, cloth and wider asbestos textile products are priced according to quantity, condition, use, location and required work category.
Can asbestos textiles require licensed removal?
Some maintenance work involving rope, yarn and woven cloth can be non-licensed. Larger, deteriorated or insulation-type textile applications require individual assessment, and a licensed contractor is used where the work falls within the licensable asbestos criteria.
Is air monitoring required for gasket removal?
Not automatically for routine lower-risk gasket removal. Analytical requirements are determined by the asbestos condition, task, work category and surrounding building occupation.
What should I send ASM for a gasket quotation?
Send the asbestos report or sample result, the number of gaskets, photographs, flange or equipment details, site address, access information, isolation arrangements and the planned shutdown or maintenance dates.
Multiple gasket programmes from £60 + VAT each
