AdBlue COSHH sheet

Also called AUS 32, diesel exhaust fluid, urea solution.

Fleets, hauliers and garages top up diesel vehicles with AdBlue. This sheet says it does not meet the criteria for classification, so it carries no hazard or precautionary statements. The sheet still recommends safety glasses and nitrile gloves.

Taken from the AdBlue (Ford, product code 6419) safety data sheet from Ford Motor Company Ltd, revision 14 June 2024. Open the data sheet. Formulas differ between products, so check against the sheet for the product you actually buy. This is a vehicle maker's sheet, dated June 2024, in a GB English version.

Hazards on the data sheet

The sheet says this product does not meet the criteria for classification, so it has no signal word, hazard statements or precautionary statements.

Workplace exposure limit

EH40/2005 has no entry for urea or AdBlue. The sheet lists a trace of ammonia (0.1 to under 0.2%), and quotes EH40's ammonia limits, but those apply to the ammonia, not to the product.

PPE

Eyes	Safety glasses, EN 166, protecting from splashes.
Hands	Protective gloves to ISO 374-1: nitrile rubber (NBR), 0.4 mm, permeation level 6 (> 480 minutes), also for splash contact (e.g. Camatril Velours 730 or comparable).
Breathing	No respiratory protection needed under normal use conditions.
Skin	Suitable protective clothing; long sleeved protective clothing.

Storage, spills and what to keep it away from

Storage	Keep cool, dry, in a closed container, protected from sunlight. Storage temperature -11 to 25 °C. Keep away from oxidizing agents.
Spills	Ventilate; avoid skin and eye contact; prevent entry to drains. Small spills: wipe up with absorbent material. Large spills: dike and absorb in vermiculite, dry sand or earth, then flush area with water.
Keep away from	Strong oxidizing agents. Strong bases.

What your assessment still has to cover

An unclassified product may fall outside COSHH's definition of a hazardous substance, and some businesses still record it to show they checked. Note storage temperature, which the sheet gives as -11 to 25°C, splashes to the eyes during topping up, and how spills are cleaned.

Fill these in for your own workplace. HSE lists them as the points an assessment considers. For a full form, use the COSHH assessment template.
