Workplace safety programs have many parts, all of which are important to keeping people safe on the job. Safety signs play a key role, though, in many aspects of safety from notifying people of tripping hazards and PPE requirements to explaining arc flash and chemical hazards. These signs must be noticeable, easy to read, and in many cases, comply with OSHA standards for safety signs. These standards can include formatting and content requirements. Since safety is considered the 6S in the 5S program, taking steps to keep workers safe is a key to a successful and productive business.
