Component STD 8-hr TWA 15-min STEL Notes
Naphtha/hydrocarbons — 1200 mg/m³ — EH40/2005

6. Frequency and duration of exposure

COSHH Regulation 6 requires the assessment to consider the amount, level and duration of exposure.

Amount used Times per day Duration per use
Small — millilitres 1–5 1–5 minutes

7. Control measures — hierarchy of controls

Elimination / substitution: Evaluated where practicable — see Section 12.

Engineering controls:

  • Use in well-ventilated area — open air preferred

Administrative controls:

  • No smoking during use
  • Do not pierce or burn can — even when empty

Personal Protective Equipment (PPE):

  • Nitrile gloves for prolonged use
  • Safety glasses
  • Respiratory protection if used in confined space

8. Storage and handling
Temperature Below 50 °C
Location Cool, ventilated store; protect from sunlight
Avoid Heat, sparks, ignition sources, temperatures above 50 °C
Container Original aerosol can

9. Emergency procedures

First aid

Route Action
Eyes Rinse with water for 15 minutes. Seek medical advice if irritation persists.
Skin Wash with soap and water.
Inhalation Move to fresh air. Seek medical attention if symptoms persist.
Ingestion Do NOT induce vomiting (aspiration risk). Seek immediate medical attention.

Spillage

Eliminate ignition sources. Ventilate. Absorb with sand/vermiculite. Dispose as hazardous waste.

Fire

Extremely flammable aerosol. Use foam, CO₂ or dry powder. Cool exposed cans with water — risk of explosion.

Emergency contacts

  • Emergency services: 999
  • NHS non-emergency: 111

Moderate Low

Risk rating methodology: Severity × Likelihood = Risk (S × L = R). See POL_HSQE_21 — Risk Assessment for the full scoring matrix.

12. Training requirements

  • Aerosol handling
  • Fire response
  • Confined-space awareness

13. Assessment outcome

Outcome
Safe to proceed with existing control measures ☑
Safe to proceed with additional actions ☐
Unsafe — do not proceed ☐

14. Monitoring and review

  • Weekly van-pack inspection
  • Annual COSHH review

User acknowledgement

Reformatted 09/09/2026 to the 16-section COSHH template. Hazard classification, exposure limits, control measures and risk rating are unchanged from Issue 2 — the migration added the persons-at-risk grid, frequency and duration of exposure (COSHH Regulation 6), the GHS pictogram grid, the assessment outcome and the signature block.

This assessment must be reviewed annually or when circumstances change — whichever is sooner.

Method statements

No field method statement calls up this substance.

It is a fleet, plant-maintenance, office or welfare item rather than something used in carrying out a field task. The method statements held on the Van Packs site cover field operations; substances used on the vehicles, in the yard workshop or in the office are controlled by this assessment and by SOP 8.5 alone.

This assessment is one of thirty held under APP_09. The substance-specific controls are above; the system that maintains them is below.

Standard applied: COSHH Regulations 2002 (undated reference), with workplace exposure limits taken from HSE EH40/2005 and hazard classification from GB CLP. Referenced undated so a new edition does not force a re-issue of every assessment.
