The application to grant an exemption has been decided as follows:
The exemption is granted to New Zealand Pharmaceuticals Limited by WorkSafe in accordance with section 220 of the Health and Safety at Work Act 2015.

The biochem facility is hereby exempt from the requirements of building type, separation distances and quantities of class 3 substances under regulations 11.36 and 11.37 of the Health and Safety at Work (Hazardous Substances) Regulations 2017, upon completion of the following works by New Zealand Pharmaceuticals Limited:
- Installation of a type 4 automatic fire and smoke detection system for the building suitable for hazardous areas that triggers a site-wide alarm or evacuation as necessary so the occupants in other buildings on the site are alerted to a potential fire situation.
- Installation of an external stairway with access from Deck 4 in the southern end of the biochem facility as described in the R. J. Nelligan & Associates Ltd report Partial fire report for section 33 variation to HSNO regulations (27 July 2017).
- Installation of photo luminescent lighting strips and exit signs to direct occupants of the biochem facility to the external stairway.
- Installation of weirs and isolating valves on the two floor drains where they discharge from the biochem facility.

Each secondary containment system must be able to contain at least 110% of the maximum volume held in the largest process vessel within each of the respective processing areas. In addition, the bunds must have the capacity to hold the quantity of foam needed to provide a foam blanket as described in point 13 below for the two processing areas. These bunds must be operational within 12 months of the date of this exemption taking effect.
- Update the standard operating procedures to include the reference to weirs and isolating valves within 1 year of the date of this exemption taking effect.
- Ensure that non-operational vehicles are not parked within 15 metres of the biochem facility. Signage must be erected to advise of this no parking requirement.

- Ensure that no class 3.1A substances are stored within the biochem facility.

- Have procedures in place, and that are tested, for evacuation of personnel at the same date as point 10 above.
- Update the site emergency response plan as these exemption conditions are completed and test the emergency response plan.
- Install within 2 years from the date of this exemption taking effect a foam suppression system in the biochem facility to provide a blanket over the secondary containment system.

- Maintain the layout of the biochem facility as shown in the applicant’s drawing numbers 36B000/0, 36B000/2, 36B000/3, 36B000/4, 36B000/5 revision E dated 31 May 2018, and 36B000/1 revision D dated 5 July 2016.

- Provide a copy of this decision to the Chief Fire Officer at the local Fire and Emergency New Zealand station.
- Hold a copy of this exemption document on-site.
This decision has been made for the following reasons:
- the extent of the exemption is not broader than is reasonably necessary to address the matters that gave rise to it; and
- the exemption is not inconsistent with the purpose of the Act; and
- an additional exit and means of escape from the biochem building has already been provided; and
- the exemption conditions will minimise the likelihood of a fire; and
- a fire suppression system will be provided.
This exemption takes effect from 29 May 2019 and expires on the close of 29 May 2024, unless it is replaced sooner or revoked.
