When transferring a cleaning chemical to a spray bottle or container, you must properly label the container or spray bottle with what it contains as long as the chemical is clearly visible. Chemicals, whether they are toxic or non-toxic, liquid or solid, must be properly labeled and kept at all times. Proper labeling and storage of chemical containers, chemical storage cabinets and appliances is important for the following reasons:
• can avoid accidental misuse of a chemical;
• can avoid unintentional mixing of incompatible chemicals;
• can help decrease the expense associated with the handling, management and disposal of "unknown" substances.
