Sara is our HSNO Team Leader, Senior HSNO Consultant and Compliance Certifier at Chemsafety. She knows the hazardous substances regulations inside out and is able to help you with all of your location compliance certificate, safety data sheet and general HSNO enquires. Whether you are building a new facility and need advice on what is required or help getting resource consent, or you just want to talk over an issue you are having on site, Sara is here to give you practical advice when you need it.  

Sara completed a Bachelor of Science with Honours in Chemistry and Environmental Science at the University of Canterbury and has been working for Chemsafety since March 2016. Since joining our team Sara has attended many compliance certifier workshops with WorkSafe and enjoys discussing the various interpretations that arise from the regulations. As she has done for many clients, if there is a way to help your site become compliant in a more effective or economical way, Sara will find it and discuss it with you.

Client Story

Sometimes its about the things you take away

Recently Sara had a client who exceeded the threshold for requiring location compliance certification for class 6.1 substances. Their site was not compliant and it would have been very expensive to make changes to their existing location. Instead, Sara was able to suggest a number of other minor changes, such as changing the frequency of orders of the substance, adding in some ventilation and adding extra security which, along with a slight change in procedure, brought the site into compliance without needing certification.
