As per the IMO, all commercial vessels must have a certain number of mandatory, hazard, safety, fire, direction, and prohibitory signs. These signs are colour coded as per their description, and are either lit by emergency lighting or are photo luminescent for at least an hour once the light source has.

SHM’s Signs and Posters conform to all regulations and requirements of the IMO. They are manufactured in high photo luminescent quality, and the raw materials and finished products are regularly tested by national accredited laboratories
