What a safety data sheet for toluene and mixtures containing it has to cover – harmonised classification, workplace limits and transport, taken from official sources.

Sources last checked: 14 October 2026 · CLP consolidated version of 1 July 2026 Author: Maximilián Pálffy, chemical engineer This page is not a safety data sheet. We do not publish SDSs of specific products – the figures come from official sources and the binding text is always the legislation itself.

Workplace limits and transport

Occupational exposure limits are national. The values below are those of Slovakia; an SDS states the limits of the country where it is supplied, together with their legal basis.

Government Regulation No 355/2006

Occupational exposure limits (Slovakia)

  • 8-hour limit: 50 ppm / 192 mg/m³
  • Short-term limit: 100 ppm / 384 mg/m³
  • Note “K”: readily absorbed through the skin
ADR 2025

Transport

  • UN 1294 toluene – class 3, packing group II
  • Label 3

What the SDS must cover

All safety data sheets follow the 16 sections of REACH Annex II. For toluene, these points need particular attention:

Section 2 Six hazard classes with H225, H361d, H304, H373, H315, H336 and pictograms GHS02, GHS08 and GHS07.
Section 8 Limits with the skin notation – in Slovakia 50 ppm (8 hours) and 100 ppm (short-term), note K.
Section 11 Information on reproductive toxicity and effects after repeated exposure.
Section 14 UN 1294, class 3, packing group II.
Section 15 REACH Annex XVII, entry 48: adhesives and spray paints for the general public must not contain 0.1 % or more toluene.
The structure of all 16 sections is described in the SDS template.
