Questions
What does COSHH mean?
COSHH is the UK regulations on the Control of Substances Hazardous to Health. A 'COSHH store' sign marks where such substances are kept.
Is this the same as a hazard label on a container?
No. Container labels follow CLP rules with red-diamond pictograms and signal words. These are area and store signs. Do not use them in place of required container labels.
Where are corrosive, flammable and poison signs?
Each has its own set; links below.
Do I need to display a sign?
That depends on your substances and risk assessment. We cannot say a sign is required.
