Spray bottles used to store and dispense degreaser taken from bulk containers must be labeled with the common name of the substance. This labeling is important for safety, to ensure proper identification, and to prevent chemical hazards in the workplace or storage areas. The label should clearly indicate the identity of the chemical inside the container to comply with safety regulations and good handling practices. This requirement aligns with OSHA and other safety guidelines advocating clear and accurate labeling for secondary chemical containers to inform users of the contents and associated hazards.
