RAMS — Flooring Installation

This RAMS covers the installation of floor finishes including carpet, vinyl, tiles, and resin systems. It addresses knee injury prevention, adhesive fume exposure, manual handling of heavy materials, and slip hazards during installation. COSHH assessments are required for adhesives, primers, and levelling compounds used in flooring work.

1. What It Covers

A RAMS for flooring installation must address the full range of activities within this work scope — from surface preparation and screeding through to the installation of sheet vinyl, carpet, luxury vinyl tile (LVT), resin flooring, ceramic and porcelain tiling, and timber flooring. Flooring installation presents a unique combination of COSHH hazards from adhesives and solvents, musculoskeletal risks from prolonged kneeling, and regulatory complexity from the UK REACH diisocyanate restriction.

The RAMS should cover substrate assessment, surface preparation (including grinding, shot-blasting, and levelling), priming, adhesive application, product installation, and finishing. Each activity must be individually assessed for COSHH exposure, ventilation requirements, and manual handling demands. Since August 2023, any operative handling polyurethane-based adhesives must hold a valid UK REACH diisocyanate training certificate — this is a legal requirement, not a recommendation.

UK REACH diisocyanate training became mandatory on 24 August 2023

Since 24 August 2023, all workers who handle products containing diisocyanates (including most polyurethane adhesives, sealants, and coatings) must have completed approved training. This applies to anyone who opens, mixes, applies, or comes into contact with these products. The training must be delivered by an approved provider and must be repeated at least every five years. Non-compliance is a breach of UK REACH and is enforceable by the HSE.

2. COSHH Substances

Flooring installation involves regular exposure to a range of hazardous substances. The COSHH Regulations 2002 require the employer to assess the risk from each substance, prevent exposure where practicable, and where prevention is not reasonably practicable, adequately control exposure. The following table sets out the principal COSHH substances encountered in flooring work.

Substance type	Typical products	Health effects	Control measures
Polyurethane (PU) adhesives	PU floor adhesives, moisture-cure PU coatings, PU sealants	Respiratory sensitisation (occupational asthma), skin sensitisation, irreversible once established	UK REACH diisocyanate training (mandatory); LEV or forced ventilation; nitrile gloves; RPE where ventilation is insufficient; health surveillance
Solvent-based adhesives	Contact adhesives, neoprene adhesives, solvent-based primers	CNS depression, dizziness, narcosis at high exposure; chronic liver and kidney damage; dermatitis	Substitute with water-based product where practicable; forced ventilation; solvent-rated RPE (A2 filter minimum); no ignition sources; atmospheric monitoring in confined areas
Epoxy resins	Epoxy floor coatings, epoxy grout, epoxy primers	Skin sensitisation (epoxy dermatitis), respiratory sensitisation from hardener vapour, eye irritation	Nitrile or laminate gloves (not latex); eye protection; LEV for mixing; COSHH assessment; health surveillance for skin; substitute where practicable
Respirable crystalline silica (RCS)	Generated during grinding, shot-blasting, or cutting concrete, terrazzo, or ceramic substrates	Silicosis, lung cancer (Category 1A carcinogen), COPD	Water suppression; on-tool extraction with H-class vacuum; FFP3 RPE; enclosure where practicable; health surveillance; WEL 0.1 mg/m3
Anhydrite screed dust	Calcium sulphate-based self-levelling screeds	Respiratory irritation, eye irritation, skin drying	Dust suppression during sanding/grinding; RPE (FFP2 minimum); COSHH assessment; ventilation of work area

Isocyanate sensitisation is irreversible

Once an operative develops respiratory sensitisation to diisocyanates, even very low subsequent exposures can trigger severe asthma attacks. There is no cure. The affected person will typically be unable to continue working with any product containing isocyanates for the remainder of their career. This makes prevention — through UK REACH training, adequate ventilation, and RPE — critical. Health surveillance must be in place for all operatives with regular diisocyanate exposure.

3. Key Hazards

The following table sets out the principal hazards associated with flooring installation, who is at risk, and the control measures that should be addressed in the RAMS.

Hazard	Who at risk	Control measures
Knee disorders (prolonged kneeling)	All flooring installers	Knee protection to BS EN 14404 (Type 2 minimum); knee pads or kneeling mats; task rotation; early symptom reporting; occupational health assessment where indicated
Isocyanate sensitisation (PU adhesives)	Operatives mixing, applying, or working near PU products	UK REACH diisocyanate training (mandatory since Aug 2023); LEV or forced ventilation; RPE; nitrile gloves; health surveillance; substitution with non-isocyanate products where practicable
Silica dust (grinding, shot-blasting)	Surface preparation operatives, adjacent trades	Water suppression; on-tool extraction (H-class vacuum); FFP3 RPE; enclosure; health surveillance; WEL 0.1 mg/m3
Solvent vapour	Operatives applying solvent-based adhesives or primers	Substitute with water-based product; forced ventilation; solvent-rated RPE (A2 filter); no ignition sources; atmospheric monitoring; time-limited exposure
Slips, trips, and falls	All operatives and adjacent trades	Housekeeping regime; secure loose materials; adequate lighting; warning signage on wet adhesive areas; clean access routes
Hand-arm vibration (HAV)	Operatives using grinders, shot-blasters, or power tools for surface prep	HAV assessment; low-vibration tools; daily exposure limit (5 m/s2 A(8)); trigger time records; health surveillance for regular users; tool maintenance
Manual handling	All flooring operatives	Mechanical handling for rolls, tiles, and pallets; limit single-person lift weights; two-person carry for heavy rolls; manual handling assessment; training
Fire risk (solvent vapour, hot works)	All persons in the area	No smoking or naked flames; solvent vapour monitoring; fire extinguisher in work area; hot work permit where heat welding vinyl; DSEAR assessment where flammable atmospheres may arise

Knee disorders are the most common occupational health issue in flooring

Flooring installers spend a disproportionate amount of their working day kneeling. Prolonged and repeated kneeling causes prepatellar bursitis, meniscal damage, and osteoarthritis of the knee. BS EN 14404 classifies knee protectors into types based on the working surface and posture. Flooring operatives should use Type 2 (or above) knee protectors that protect against both flat and uneven surfaces, combined with task rotation and regular breaks from the kneeling position.

4. Competence Requirements

Flooring installation requires trade-specific qualifications, and regulatory changes in recent years have introduced additional mandatory training requirements. The RAMS must confirm that all operatives hold the required competence and that evidence has been verified before work begins.

Qualification / Training	Scope	Status / Notes
NVQ Level 2 Floorcovering (CFA/FITA pathway)	Carpet, vinyl, LVT, and resilient flooring installation	The primary trade qualification for flooring operatives. Required for CSCS Blue Skilled Worker card. CFA (Contract Flooring Association) and FITA (Flooring Industry Training Association) are the main awarding pathways.
Screed installer qualification	Sand and cement screeds, anhydrite (calcium sulphate) screeds, flowing screeds	Separate trade qualification from floorcovering. Required where operatives are installing screeds as part of the flooring package.
UK REACH diisocyanate training	All workers who handle products containing diisocyanates (including PU adhesives, sealants, and coatings)	Mandatory since 24 August 2023. Must be delivered by an approved provider. Must be repeated at least every 5 years. Non-compliance is a breach of UK REACH.
Surface preparation training	Grinding, shot-blasting, floor levelling, moisture testing, substrate assessment	Essential for operatives carrying out surface prep. Should include COSHH awareness for RCS and training on dust extraction equipment.
CSCS card	Site access and competence verification	CSCS Green Labourer cards are no longer accepted for skilled flooring work on many sites. Operatives must hold a Blue Skilled Worker card or be on a qualifying NVQ pathway with a Provisional card.

CSCS Green Labourer cards are no longer valid for skilled flooring work

Many flooring operatives historically worked under CSCS Green Labourer cards, which require only a basic health and safety test and no trade qualification. Major contractors and principal contractors increasingly reject Green cards for skilled flooring installation, requiring a Blue Skilled Worker card or equivalent. The RAMS should specify the minimum CSCS card level required and ensure all operatives meet this standard before mobilisation.

5. Common Mistakes

No UK REACH diisocyanate training for PU adhesive users

Since 24 August 2023, any worker who handles products containing diisocyanates must hold a valid UK REACH diisocyanate training certificate. This includes anyone who opens, mixes, or applies polyurethane adhesives, sealants, or coatings. Non-compliance is a breach of UK REACH and is enforceable by the HSE. The RAMS must require evidence of training for every operative who will handle these products.

Inadequate ventilation when using solvent-based adhesives

Solvent-based adhesives release volatile organic compounds (VOCs) that can rapidly accumulate in enclosed or poorly ventilated areas. Operatives have been overcome by vapour when applying contact adhesives in small rooms with no forced ventilation. The RAMS must specify the ventilation requirements for each product and prohibit the use of solvent-based adhesives in unventilated spaces.

No knee protection or inadequate knee protection

Flooring installers spend the majority of their working day kneeling. The RAMS must specify that knee protection to BS EN 14404 is mandatory for all kneeling tasks. Generic foam knee pads that do not meet BS EN 14404 are not adequate. The knee protection must be appropriate for the working surface and the duration of the kneeling task.

No COSHH assessment for surface preparation dust

Grinding, shot-blasting, and levelling concrete substrates generates respirable crystalline silica (RCS) with a WEL of just 0.1 mg/m3. A separate COSHH assessment must be in place for all surface preparation activities that disturb concrete, terrazzo, or ceramic substrates. The assessment must specify dust controls (water suppression, on-tool extraction, enclosure) and RPE requirements (FFP3 minimum for RCS).

Accepting CSCS Green cards for skilled flooring work

CSCS Green Labourer cards do not demonstrate trade competence for flooring installation. Operatives installing floorcoverings should hold an NVQ Level 2 in Floorcovering and a CSCS Blue Skilled Worker card. The RAMS should specify the minimum qualification standard required and the principal contractor should verify card type at induction.

6. Frequently Asked Questions

Does the UK REACH diisocyanate training requirement apply to all flooring operatives?▾

It applies to all workers who handle products containing diisocyanates. This includes most polyurethane adhesives, sealants, and coatings used in flooring installation. If an operative opens, mixes, applies, or is likely to come into skin or inhalation contact with a diisocyanate-containing product, they must hold a valid training certificate. Operatives who only work with water-based or solvent-based adhesives that do not contain diisocyanates are not covered by this specific requirement, but other COSHH obligations still apply.

What standard of knee protection is required for flooring work?▾

The RAMS should specify knee protection to BS EN 14404, which is the European standard for knee protectors for work in a kneeling position. Type 2 protectors (suitable for flat and uneven surfaces) are the minimum recommended for flooring installation. Type 1 protectors (flat surfaces only) may be suitable for some tasks but do not provide adequate protection on uneven or hard substrates. Knee protectors must be properly fitted, regularly inspected for wear, and replaced when the cushioning material is compressed or damaged.

Is health surveillance required for flooring installers?▾

Health surveillance is required where operatives are regularly exposed to respiratory sensitisers (diisocyanates from PU adhesives), skin sensitisers (epoxy resins), or respirable crystalline silica (from surface preparation). The surveillance programme should include respiratory function testing for isocyanate and RCS exposure, and skin checks for epoxy exposure. For knee disorders, an occupational health assessment should be offered where operatives report symptoms. The COSHH assessment must identify which operatives require surveillance and at what frequency.

Can water-based adhesives always be substituted for solvent-based products?▾

Not always. Water-based adhesives are suitable for many flooring applications and should be used in preference to solvent-based products wherever practicable. However, some substrates, products, or performance requirements (such as moisture resistance or rapid grab) may require solvent-based or polyurethane adhesives. Where substitution is not practicable, the COSHH assessment must document the reasons and specify the controls required to adequately manage exposure — including ventilation, RPE, and atmospheric monitoring.
