How long to hold onto an SDS? Hi Tanya,
What an interesting question! The US (OSHA) requires an SDS to be kept for 30 years as part of the employees exposure records.
Could we then say under HSWA General Risk and Workplace Management Regs - s32 Duties relating to exposure monitoring - that the same thing applies to NZ as records must be kept for 30 years, and measurement and evaluation of exposure to a health hazard would include the data from an SDS??
I know for us, this would be a paperwork (electronic or otherwise) nightmare, but it's got me thinking.
