Question juridique clé
Whether the insurer may reduce the compensation for gross negligence in handling linseed oil and contaminated materials.
Solution extraite
The reduction was not permitted because the product warnings were inadequate and linseed oil is not generally known to the public; only slight negligence could be attributed.
Motifs extraits
Clear warnings about self-ignition and disposal of contaminated materials were required. The packaging and leaflet did not explain the actual danger or how to dispose of contaminated newspapers and cloths sufficiently; the appellants therefore did not omit elementary precautions in a grossly negligent manner.
