Many commonly used laboratory chemicals are classified as Hazardous Substances under New Zealand legislation because they have the potential to cause explosion or fire, or harm to human health or the environment.

Laboratories where Hazardous Substances may be in use are marked as HSNO Exempt Laboratories and must comply with the Code of Practice for CRI and University Exempt Laboratories. The requirements of the Code of Practice are included in the University of Otago HSNO Exempt Compliance manual, which also includes additional requirements that must followed in University of Otago laboratories.
