In the United States, non-production laboratories are exempted from the OSHA-GHS Hazard Communication labeling requirements. Good laboratory safety practices should include labeling of secondary containers holding hazardous chemicals. The write-in GHS label with self-lamination available from HCL at http://www.hclco.com/Laboratory_Blank_Write_In_GHS_Label_p/wi-ghs.htm is small enough to be applied to most laboratory secondary containers.
