COSHH Assessment

CompanyExample Decorating Ltd
SiteUnit 3, Riverside Business Park, Leeds LS1 4AB
Assessed byJ. Smith (supervisor)
Date1 October 2026

Prepared under the Control of Substances Hazardous to Health Regulations 2002 (as amended). Read each product's safety data sheet (SDS); where it conflicts with this assessment, follow the SDS and update this record.

1. Solvent-based gloss paint

Use: Painting doors, frames and skirting | Quantity: 5 litres per job | Frequency: Weekly | Exposed: Decorators

Hazard statements: H226, H336 (May irritate airways, cause drowsiness or damage organs after a single exposure; Flammable or combustible liquid and vapour)

Exact hazards depend on solvent, resin and pigments. Control vapour and ignition; read the SDS.

Control measures

  • Substitute lower-volatility or less hazardous material.
  • Use local exhaust ventilation and keep containers closed.
  • Prevent entry into poorly ventilated areas.
  • Limit duration and quantity and prohibit ignition sources where vapours are flammable.
  • Substitute a water-based or higher-flash-point product where practicable.
  • Keep lids closed and use minimum working quantities.
  • Control ignition sources, static and hot work.
  • Provide suitable ventilation and assess hazardous zones where applicable.

PPE

  • eye and skin protection from the SDS
  • suitable face-fit-tested RPE only where engineering control is insufficient
  • SDS-specified skin and eye protection
  • anti-static clothing or footwear only where the DSEAR assessment requires it

Storage

  • Keep closed in a cool, ventilated place away from incompatibles and ignition sources.
  • Use a suitable flammable-liquid cabinet for working stock and a compliant store for larger quantities.

First aid

  • Move to fresh air without endangering rescuers.
  • Seek urgent medical advice for persistent symptoms, confusion or suspected organ effects.
  • Move inhalation casualties to fresh air and obtain medical advice as the SDS directs.
  • Raise the alarm and evacuate for fire or major vapour release.

Spills and disposal

  • Remove ignition sources if safe, ventilate and follow the SDS.
  • Eliminate ignition sources if safe, ventilate, contain with compatible materials and prevent drain entry.

Health surveillance: consider - depends on substance and residual exposure consider - depends on solvent health hazards, not flammability alone

  • Assess confined-space and oxygen-deficiency risk separately.
  • Confirm any workplace exposure limit.
  • Complete DSEAR assessment where applicable.
  • Confirm flash point, quantity and ventilation.

2. White spirit

Use: Cleaning brushes | Quantity: 1 litre | Frequency: Weekly | Exposed: Decorators

Hazard statements: H226, H304, H336, H411 (May irritate airways, cause drowsiness or damage organs after a single exposure; May be fatal if swallowed and enters airways; Flammable or combustible liquid and vapour; Hazardous to aquatic life with long-lasting effects)

Grades differ. Prevent vapour accumulation and never induce vomiting after ingestion.

Control measures

  • Substitute lower-volatility or less hazardous material.
  • Use local exhaust ventilation and keep containers closed.
  • Prevent entry into poorly ventilated areas.
  • Limit duration and quantity and prohibit ignition sources where vapours are flammable.
  • Prevent siphoning by mouth and hand-to-mouth transfer.
  • Use closed dispensing and clearly labelled containers.
  • Never decant into food or drink containers.
  • Substitute a water-based or higher-flash-point product where practicable.
  • Keep lids closed and use minimum working quantities.
  • Control ignition sources, static and hot work.
  • Provide suitable ventilation and assess hazardous zones where applicable.
  • Substitute a less environmentally hazardous product where practicable.
  • Use minimum quantities and prevent discharge.
  • Provide contained washout and cleaning arrangements.

PPE

  • eye and skin protection from the SDS
  • suitable face-fit-tested RPE only where engineering control is insufficient
  • SDS-specified gloves
  • eye protection where splash is possible
  • SDS-specified skin and eye protection
  • anti-static clothing or footwear only where the DSEAR assessment requires it
  • PPE required for the product's health hazards and spill method

Storage

  • Keep closed in a cool, ventilated place away from incompatibles and ignition sources.
  • Keep closed, upright and away from food and drink.
  • Use a suitable flammable-liquid cabinet for working stock and a compliant store for larger quantities.
  • Store in labelled secondary containment away from surface-water and foul drains.

First aid

  • Move to fresh air without endangering rescuers.
  • Seek urgent medical advice for persistent symptoms, confusion or suspected organ effects.
  • Call 999 or a poison service immediately.
  • Do not induce vomiting.
  • Keep the casualty at rest and provide the SDS.
  • Move inhalation casualties to fresh air and obtain medical advice as the SDS directs.
  • Raise the alarm and evacuate for fire or major vapour release.
  • Follow the SDS for human exposure.

Spills and disposal

  • Remove ignition sources if safe, ventilate and follow the SDS.
  • Remove slip and ignition risks and follow the SDS cleanup instructions.
  • Eliminate ignition sources if safe, ventilate, contain with compatible materials and prevent drain entry.
  • Contain and recover; do not wash into drains, soil or watercourses; use an authorised waste route.

Health surveillance: consider - depends on substance and residual exposure consider - depends on solvent health hazards, not flammability alone

  • Assess confined-space and oxygen-deficiency risk separately.
  • Confirm any workplace exposure limit.
  • Ensure first-aid instructions state not to induce vomiting.
  • Complete DSEAR assessment where applicable.
  • Confirm flash point, quantity and ventilation.
  • Confirm disposal route and whether environmental incident notification is needed.

3. Vinyl matt emulsion

Use: Walls and ceilings | Quantity: 20 litres per job | Frequency: Daily | Exposed: Decorators

Hazard statements: none entered

May contain preservatives that cause allergic skin reactions. Sanding old coatings creates a separate dust and possible lead risk.

Control measures

  • Keep rooms ventilated during application and drying.
  • Prefer brush or roller; if spraying is necessary, assess the mist and use enclosure, segregation and extraction, adding RPE only where these do not adequately control exposure.
  • Avoid skin contact; wash hands before eating, drinking or smoking.
  • Many water-based paints contain preservatives (labelled EUH208 or H317) that can cause allergic skin reactions; check the SDS.
  • Do not sand or strip old coatings until they have been checked for lead (see lead-containing paint).
  • Before sanding or stripping coatings in a building built or refurbished before 2000, check the asbestos survey; do not sand suspected asbestos-containing textured coatings.

PPE

  • Chemical-resistant gloves selected from the paint SDS and the glove maker's data for the product and task
  • Eye protection when working overhead or spraying
  • RPE suitable for paint mist if spraying (see SDS section 8)

Storage

  • Store frost-free with lids sealed.

First aid

  • Eyes: rinse with clean water for at least 10 minutes.
  • Skin: wash with soap and water; seek advice if a rash develops.

Spills and disposal

  • Contain and absorb with sand or absorbent; do not wash into drains or watercourses.

Health surveillance: Where repeated skin contact with a sensitising product (H317 or a sensitising preservative) makes dermatitis reasonably likely, provide skin checks set up with occupational health advice.

  • Check the SDS for EUH208 or H317 and record anyone known to be sensitised.
  • Review regularly, and immediately if the product, SDS, task, quantity, people or controls change, or after a spill, incident, near miss or health surveillance finding.

4. Gypsum filler

Use: Filling cracks before painting | Quantity: 2 kg | Frequency: Daily | Exposed: Decorators

Hazard statements: none entered

May not be CLP-classified but mixing and sanding generate nuisance dust; use the SDS and process assessment.

Control measures

  • Add powder to water slowly and mix at low speed to limit airborne dust.
  • Prevent dust with low-dust mixing and on-tool extraction (M-class) when sanding; do not use RPE instead of dust control.
  • Clean up with an H- or M-class vacuum; do not dry sweep.
  • Bags are typically 25 kg: use mechanical aids or two-person lifts and store at waist height where possible.
  • Check the current SDS for cement, lime or other alkaline additives. Where present, wet product can cause skin burns, dermatitis and serious eye injury: follow the product-specific controls.
  • Check extraction works before use; have LEV thoroughly examined and tested at least every 14 months.

PPE

  • Suitable RPE (e.g. FFP3) where residual dust remains after controls, such as prolonged sanding or work in confined rooms
  • Tight-fitting masks must be face-fit tested for the exact make, model and size; wearers must be clean-shaven where the mask seals and fit-check before each use. Use powered loose-fitting RPE where a seal cannot be achieved.
  • Safety glasses or goggles when mixing and working overhead
  • Gloves to avoid prolonged skin contact; waterproof, alkali-resistant gloves if the SDS shows lime or cement

Storage

  • Store bags dry, off the floor and in stable stacks.

First aid

  • Eyes: rinse with clean water for at least 10 minutes; seek medical advice if irritation persists.
  • Inhalation of dust: move to fresh air.
  • Skin: wash with soap and water.

Spills and disposal

  • Collect dry powder with an H- or M-class vacuum or damp methods; avoid dry sweeping.

Health surveillance: Not normally required where gypsum dust exposure is adequately controlled; assess the need under COSHH if regular residual exposure makes a skin or respiratory effect reasonably likely.

  • Confirm the product SDS hazard statements; add any H-codes shown in section 2.
  • Review regularly, and immediately if the product, SDS, task, quantity, people or controls change, or after a spill, incident, near miss or health surveillance finding.

Substances created by the work

Wood dust

  • Use on-tool extraction connected to a suitable dust extractor.
  • Use fixed local exhaust ventilation at woodworking machines and have it examined and tested at least every 14 months unless a different statutory interval applies.
  • Vacuum with suitable dust-rated equipment; do not dry sweep or use compressed air.
  • Keep exposure below the workplace exposure limit and as low as reasonably practicable.
  • Separate dusty work from clean and welfare areas.

PPE: Suitable face-fit-tested RPE for residual exposure, eye protection for machining. Health surveillance: Required where there is a reasonable likelihood of occupational asthma or dermatitis; arrange suitable respiratory and skin surveillance with occupational-health advice.
