COSHH Assessment — Hydraulic Oil ISO 32 Premium Mineral

Confirmed against the container label — the drum is ExoPro, not Morris

The drum was photographed on 24/09/2026. ExoPro Hydraulic 32 Premium Mineral Hydraulic Fluid, 5 litre, part U41255L, from FPS of Milton Keynes, marked "PUMP OIL" in red pen. It carries no signal word and no pictogram, which is what an unclassified product looks like on the shelf.

That settles which of the two candidate sheets applies. ExoPro's own sheet for U412 Hydraulic 32, issue 1.0 of 06/07/2021, records the product as not classified under GB CLP and matches this assessment. The Morris Lubricants Triad 32 sheet found during the 27/09/2026 search is a different brand and is set aside; it is retained outside the portal only as a record of the search.

No discrepancy remains. The label, the supplier sheet and this assessment all say the same thing. The assessment was approved on 29/09/2026 and is off draft.

One filing action. The ExoPro sheet is reached by link and is not held locally.

Assessment finalised and signed 29/09/2026. A local copy of the ExoPro sheet is still to be filed so the assessment does not depend on a supplier link — owner Leanne Mason, target 31/10/2026.

2. Hazard classification

Overall classification: Most ISO VG 32 hydraulic oils are not classified as hazardous under CLP in the supplied form. The hazard on AMWS work is not the oil in the drum — it is pressurised release.

Signal word: None required for the fresh product

Hazard statements (H-codes)

Code Statement
— Not classified as hazardous in the supplied form

Precautionary statements (key P-codes)

Staff Public Visitors Contractor Workers Young / Pregnant
☑ ☐ ☐ ☑ ☑ ☐

4. Routes of exposure

  • Inhalation: Negligible at ambient temperature; oil mist where a line fails under pressure
  • Skin contact: Repeated contact causes dermatitis
  • Eye contact: Irritation on splash
  • Injection: The serious hazard. A pinhole leak in a hydraulic line will inject oil through intact skin at working pressure. This is a surgical emergency and it does not look serious at first — see the first-aid note below
  • Ingestion: Unlikely

5. Workplace exposure limits (HSE EH40/2005)

Component STD 8-hr TWA 15-min STEL Notes
Oil mist, mineral — 5 mg/m³ 10 mg/m³ EH40/2005. Applies to mist generated by spraying, splashing or hot work

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
Medium — litres 1–5 times per day 6–30 minutes

7. Control measures — hierarchy of controls

Elimination / substitution

  • Not practicable — grade is specified by the plant manufacturer

Engineering controls

  • Hydraulic hoses inspected as part of the daily walkaround check
  • Never search for a hydraulic leak with a hand — use a piece of cardboard held at arm's length
  • System depressurised before any hose is broken
  • Drip tray and funnel for top-up

Administrative controls

  • Hose condition and date recorded in the plant maintenance record
  • Leaks reported and the machine taken out of service, not run on
  • Spill kit within reach of the working position

Personal protective equipment

  • Nitrile gloves
  • Safety glasses — mandatory when working on a hydraulic system
  • Overalls

8. Storage and handling
Temperature Ambient
Location Yard COSHH cabinet, bunded
Avoid Strong oxidisers; contamination with grit or water
Container Original container, closed and clearly labelled

9. Emergency procedures

First aid

Route Action
Eyes Rinse with water for several minutes.
Skin Wash with soap and water.
*Injection injury* Call 999 and say the words 'high-pressure injection injury'. Do not wait to see whether it develops. The entry wound may be a pinprick and appear trivial; the injury underneath is not. Immobilise the limb, keep the casualty warm, and take the product container to hospital.
Inhalation Move to fresh air if mist has been generated.
Ingestion Rinse mouth. Do not induce vomiting. Seek medical advice.

Spillage

Absorb with oil absorbent or sand. Protect the nearest drain first. Dispose as hazardous waste. See SOP 9.3.

Fire prevention

Combustible when heated. Foam, dry powder or CO₂. A pressurised leak onto a hot surface is an ignition risk.

Emergency contacts

  • Emergency services: 999
  • NHS non-emergency: 111
  • AMWS supervisor: Jason May
  • HSQE support: Sean Ashton (Onyx Operations)

10. Waste disposal

Hazardous waste, EWC 13 01 10*. Authorised waste-oil contractor with a consignment note.

11. Risk rating

Before controls With controls
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

  • Hydraulic system safety and the injection-injury hazard — the item on this assessment that most needs briefing
  • Daily walkaround hose inspection
  • Spill response — SOP 9.3
  • Dermatitis 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 COSHH cabinet inspection by the Site Supervisor
  • Annual COSHH review, or sooner on change of product, supplier or task
  • Review immediately if the SDS obtained differs from the profile assumed above

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.
