Employees have both a need and right to know the hazards of the chemicals they are exposed to when working, per OSHA. Employers must take protective measures to prevent dangerous situations from occurring and signs are required to be posted throughout all business that involves chemicals of any kind. The HCS (Hazardous Communication Standard) requires informational signs for both physical hazards, such as flammability and health hazards such as irritation, lung damage, and cancer to be posted throughout a workplace. Stay compliant and keep others safe with Hazmat signs that inform and protect. Communicate biohazards, cancerous hazards, explosives, combustibles, flammable chemicals and potable and non-potable water with an effective message on a material that's suitable for the environment.
