Worker Right to Know

17 Worker Right to Know Chapter 140—Public Safety/Emergency Response Right to Know Iowa Public Safety/Emergency Response Right to Know requires departments to identify and label hazardous chemical storage areas. Labels or signs conform to the National Fire Protection Association’s (NFPA’s) standard system for identifying fire hazards of chemicals. Signage rules (based on NFPA standard 704-1980) have been adopted under Iowa code. Signs shall identify health, flammability, reactivity, and any special hazards. Each category shall indicate severity numerically by five classifications, with “4” indicating a severe hazard and “0” indicating no hazard. Where posting of signs could be misleading due to small quantities on hand, the posting requirement may be waived. Consult the Hazard Communication Standard or contact EH&S at (515) 294-5359 for details on posting requirements. Chemical inventories and locations of hazardous chemicals will be made available to the Ames Fire Department, upon their request. 1910.1200 Worker Right to Know The Iowa State University WRTK Program is intended to ensure compliance to this standard. The statute requires the university to ensure that information concerning chemical hazards is transmitted to affected employees. This must be accomplished by a comprehensive hazard communication program which includes: • a written program • employee information and training • container labeling requirements • safety data sheets • department-specific chemical inventories • contractor work at Iowa State University • non-routine tasks • trade secrets
