COSHH Assessment — STIHL HP 2-Stroke Engine Oil (100 ml)

Safety data sheet filed — it states no classification, and this assessment does

STIHL's own sheet for the product is now held. Safety data sheet for S0015 2-Stroke Oil, product HP, STIHL code 0781-319-84, issued by ANDREAS STIHL AG & Co. KG. The product code matches the code recorded against this assessment, so the lead is confirmed and the product is the right one.

The document cannot carry the classification. It is written to Directives 67/548/EEC and 1999/45/EC, which CLP replaced in June 2015. It records the classification as "Void", and it carries no revision date anywhere. A sheet that predates GB CLP is not a GB CLP determination.

This assessment keeps Danger, H304 and H412. It is the more onerous of the two positions and it is what the assessment was approved on, so it stands until STIHL GB supply the CLP-format sheet.

Owner: Sean Ashton — request the current CLP sheet for HP 0781-319-84 from STIHL GB. Target: 31/10/2026.

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

Held at Issue 2, 01/06/2026 on the Van Packs site and listed in APP_24. The method statement sets out the safe system of work for the task; this assessment controls the substance used within it.

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.
