National Marker Company signage with legend ?DANGER - No smoking, matches or open flames? is often used to alert people about certain regulations to be followed at a workplace. This signage restricts employees and general public from smoking, lighting matches or open flames in the indicated areas. Often found at commercial and industrial locations and jobsites, this sign is used as a safety measure where smoking and open flames can lead to fire-related safety hazards. Jobsites that handle possibly inflammable solvents, chemicals or materials are usually very specific about putting-up such danger signage across the premises. The graphics make the message easy to understand. The rectangular danger sign complies with ANSI standards and has NMC Sign Muscle coating to protect the text and graphic against fading, scratches, scuffing, mold, and moisture.
