National Marker Company signage with legend “DANGER - BATTERY CHARGING AREA NO SMOKING OR OPEN FLAMES” is often used to forbid people from smoking near workplaces with a battery charging area. Often found at electrical-powered 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. This OSHA signage is easy to spot and read, ensuring working personnel and visitors are immediately cautioned about smoking-related prohibitions/restrictions.
