Handling and Storage of Hazardous Goods on
NZ King Salmon Seafarms
This document gives an outline on the transport, storage and handling of hazardous goods on NZ
King Salmon seafarms. Additional information can be found in the following documents which guide
operations on NZ King Salmon's existing farms and are attached to this report.

The NZ King Salmon Oil Spill Plan has been submitted and is awaiting approval by the
Marlborough District Council Harbour Master.
Types of hazardous goods:
Below is a list of the items stored onsite at NZ King Salmon's farms. Approximate quantities for larger
volume items have been included. Other items such as aerosols, oils, and cleaners are kept in small
quantities of approx 8L or less.
Diesel (1500 – 5000L)
Petrol (40 – 500L)
LPG (95L)
Various aerosols (paints, lubricants etc)
Various oils – engine and hydraulic
Disinfectants, cleaning chemicals, formalin
Compliance and training:
NZ King Salmon complies with Hazardous Substances and New Organisms Act 1996 (HSNO)
regulations.
Diesel is stored in quantities below HSNO trigger levels however, as it is stored in tanks connected to
machinery ‘Stationary Container Certificates’ are required under HSNO.
Petrol is stored in quantities that exceed HSNO trigger levels at some sites. These sites are required
under HSNO to have ‘Location Test Certificates’.
NZ King Salmon does not hold other hazardous goods above HSNO trigger levels on its existing
seafarm sites.

NZ King Salmon undertakes annual auditing by an HSNO Test Certifier to ensure compliance with the
regulations and ensures it follows best practice in the storage of hazardous goods.
NZKS has trained Approved Handlers as required by HSNO for each site. Seafarm employees
undertake a variety of training including oil spill, fire, confined spaces and first aid to deal with any
potential issues. All training is recorded on a HRSS database with monthly reports on training status
sent to farm management. Copies of Material Safety Data Sheets (MSDS) are kept on all sites
available to staff in the event of an accident.
Transport and transfer:
Hazardous goods are transported to sites by NZ King Salmon vessels and Barge Contractors.
Contractors' barges are the primary mode of transport for bulk goods (diesel, petrol and LPG). Other
hazardous goods would normally be transported on a NZ King Salmon vessel.
NZ King Salmon's policy for transport of hazardous substances by NZ King Salmon vessels is outlined
in the Vessel Operation Policy (section 13.1.6). This details the goods and quantities to be carried.
Contractors are responsible for management of any hazardous goods on their vessels. NZ King
Salmon however undertakes auditing of contractors to ensure hazards are managed in the NZ King
Salmon workplace. This process is outlined in the NZ King Salmon Contractor Safety Handbook.
Diesel and petrol are transported in a variety of containers:
Bulk tanks on the contractor barge (diesel)
250L Drums (petrol and diesel)
25L plastic containers (petrol and diesel)
Transfer from bulk tanks by Barge Contractors to NZ King Salmon Barge tanks is by pump. This
process is visually monitored and is specifically covered in the Oil Spill Policy due to the volumes
transferred. The inlet pipes on NZ King Salmon barge tanks are bunded to capture small spills that
may occur during transfer.
250L drums delivered to the sites are either stored in Dangerous Goods Sheds or the fuel transferred
into storage tanks inside barge hulls. Transfer from 250L drums is done by hand pump. Drums are
decanted into 25L containers for use in small plant at the sites.
25L containers delivered to the site are stored in Dangerous Goods Sheds or Cabinets. 25L
containers are used to refill small plant at the sites.
LPG is transported to the sites in 45kg cylinders and is primarily used for domestic purposes. These
cylinders are connected to the gas line on the barge.
Storage and containment:
NZ King Salmon storage of petrol and diesel is compliant with HSNO regulations and are stored in
tanks below barge decks or in Dangerous Goods Cabinets and Sheds.
The tanks below barge decks are subject to HSNO Stationary Tank Certification. The barge hulls
provide bunding to contain any potential leak or spill from these tanks.

Dangerous Goods Sheds and Cabinets in which petrol is stored all must meet HSNO standards in
order to gain a ‘Location Test Certificate’. This takes into account location, construction, venting and
bunding etc. NZ King Salmon applies this standard to all sites even when volumes are below HSNO
trigger levels and they do not require certification.
LPG is stored on the barges in an outside vented area and away from ignition sources. The cylinders
are secured to prevent them moving. This setup is similar to a standard domestic installation.
Other hazardous goods (oils etc) are stored in Dangerous Goods Cabinets and Sheds.
The Seafarm Hazard Register contains hazards and control associated with the storage and transfer
of hazardous goods.
In the event of a spill NZ King Salmon farms have Oil Spill Kits onsite. These kits have a capacity of
approx 150L.
The pictures below provide and example of the storage on NZ King Salmon sites.
