27 Labeling and Disposal Workplace Labels OSHA has not changed the general requirements for workplace labeling.Labels must be legible and fade resistant or not easily removed in anyway.Employers have the option to create their own workplace labels.Employers are not responsible to update labels on shipped containers however, must re-label items if the labels are removed or defaced.Workplace labels can either provide all required information on the original chemical manufacturer’s label or, the product identifier and words, pictures, symbols or a combination of these.If the employer is aware of newly-identified hazards that are not disclosed on the label, the employer must ensure that the workers are informed.Employers may continue to use rating systems such as National Fire Protection Association (NFPA) diamonds or HMIS requirements for workplace labels as long as they are consistent with the requirements of the Hazard Communication Standard and the employees have immediate access to the specific hazard.
28 Labeling and Disposal (CONT.) Containers shall be labeled with the following information:Used-chemical categoryName of chemical(s) in the containerApproximate percentage of each chemical (if mixed)Date preparedName of teacher or room numberChemical Waste DisposalAll hazardous waste containers must be properly labeled with name and address of school, composition and physical state of the waste, and accumulation date.It is unlawful to store hazardous wastes at school sites for longer than 90 to arrange for the pickup of hazardous materials and/or wastes.
29 Labeling and Disposal (CONT.) Chemical Waste DisposalIf used chemicals become reclassified as hazardous waste, their containers willbe relabeled as such and segregated into the following classes for disposal(EPA categories):Ignitable: Materials capable of causing fire.Corrosive: Aqueous solutions with a pH less than or equal to 2 or greater than or equal to 12.5.Reactive: Substances that are unstable, explosive, water reactive, or generate toxic gases.Toxic: Substances that are harmful to human health such as arsenic, barium, cadmium, chromium, lead, mercury, selenium, silver.Other waste not falling into one of the above classes should be identified by chemical names.
30 Labeling and Disposal(cont.) Labels must be legible, in English, and prominently displayed. Other languages may be displayed in addition to English. Chemical manufacturers, importers, and distributors who become newly aware of any significant information regarding the hazards of a chemical must revise the label within six months. Each pictogram consists of a symbol on a white background framed within a red border and represents a distinct hazard(s). The pictogram on the label is determined by the chemical hazard classification.
