Reviews
Purchased for use in our workshop where hazardous substances are stored. The sign is well printed and gets the message across clearly.
The warning is bold and easy to recognise from a distance. A useful addition to our workplace safety signage.
Clear and professional sign that makes the dangerous substance warning immediately noticeable. Good quality and ideal for our chemical storage area.
