• On entry to a site it is necessary for an Enforcement Officer to identify the person in charge and identify to themselves by means of their warrant. Some crucial pieces of information are required to conduct an effective inspection that suitably measures the HSNO component and these are included in the checklist below. The checklist below may also be used by NZ sites in advance of the site inspection by a Test Certifier. It gives an indication of what needs to be prepared in advance and what the Certifier/Enforcement Officer will be checking during their visit.
    For further information or if you have any questions please contact SHEQ, NZ.

  • Have you identified and classified all your hazardous substances and dangerous goods stored on: a) Your premises b) Your storage contractor's premises c) Your consignment stocks on customer premises?

  • Do the premises contain a specified quanitity of hazardous substances that exceed the trigger quantity specified in Annex A or B of the HSNO regulations.

  • Are all tank connections clearly marked to indicate the function of each?

  • Site Plans. Site layout, with boundaries, buildings and hazardous substances locations.

  • Site Plans. Hazardous Zones (for flammables).

  • Regarding tanks - is a plate permanently attached to the tank to provide appropriate information, e.g. date of issue of the tank, test certification, etc.

  • Site Plans. Control Zones (for flammables and oxidisers).

  • Site Plans. Are there hazardous atmosphere zones and are the sources of potential ignition clearly understood.

  • Is there a register or inventory of hazardous substances on site and available? This is stored in Chem Alert and managed by SHEQ. Site must have up-to-date hard copy available. If any changes are needed contact SHEQ NZ.

  • Are Safety Data Sheets (SDS) available in electronic form or as a hard copy - accessible within 10 minutes if held off site? These are available on the BOC Internet. Do not keep hard copies of these as they get out of date.

  • Summary SDS available in folder? They are not full MSDS, but have the information that would be needed in an emergency and meet HNSO requirements for the provision of information.

  • Are the correct product labels on containers? All containers of hazardous substances need to be clearly labelled to show their contents.

  • Site Emergency Plan. IMS-25-11-SITE needs to be up-to-date. Hard copies to be available.

  • General Emergency Plan. IMS-25-12-GSP hard copy available.

  • Emergency drills carried out. Is there an emergency plan and emergency management procedures and have emergency drills and procedures been practised? The need to practice emergency procedures is a requirement under HSNO. Need copies of fire evacuations and hazardous substances trails carried out. Show records of completed quarterly scenarios sent out by SHEQ.

  • Fire extinguishers in place. Fire extinguishers maintained and within 30m of hazardous substances areas.

  • Are staff trained to handle the hazardous substances on site (this is an HSE requirement). Approved Handlers available for site. Need to have copies of Approved handler Certificates available. Where necessary, are there correctly certified people in place, like approved handlers or approved fillers? The latter is a HSNO matter triggered by specific quantities.

  • Approved Fillers Certificates available where applicable. Anyone filling cylinders or other pressurised vessels the gas must be an Approved Filler. Does not apply to decanting LIN. Note that Test Certifier may not ask to see these as they do not need to see them to issue a Location Test Certificate. However, it is a legal requirement so is a good idea to check.

  • Signage in place, warning of presence of hazardous substances. Are the signs: - visible at entrance to site? - understandable? - Communicating the specific requirements? - clearly visible and legible from 10 meters away? - sited so to be visible from all approaches? Are

  • Signage in place, warning of presence of hazardous substances.. Signs at all entrances to areas where hazardous substances are stored.

  • Signage in place, warning of presence of hazardous substances. Signs for specific hazardous stores in place, i.e. LPG sign on LPG store.

  • Signs for specific hazardous stores in place, i.e. LPG sign on LPG store. Signs on bulk tanks.

  • Signage in place, warning of presence of hazardous substances. All signs in good condition. Do the signs: a) advise the premises contain hazardous substances? b) describe the hazardous property and the nature of the hazard(s)? c) describe the precautions necessary to predict the unintended. - initiation of an explosive. - ignition of a flammable substance - combustion - accelaration of a fire? - thermal decopmposition involving an oxidising substance of organic peroxide? d) Identify the appropriate emergency response agency or personnel and the means of contacting them? e) Provide advice to trained persons and the emergency services of the correct actions in which to take in an emergency?

  • Segregation. Need to ensure oxidisers are separated from flammable by at least 3m, 5m where more than 200m3 oxygen is present. Or a fire rated wall.

  • Segregation from sources of ignition. For oxidisers, no sources of ignition within 5m where they are manufactured or used, or 3m where containers kept closed.

  • Quantity of flammable gas in inadequately ventilated storage areas meets requirements. If gas dock, or other storage area, is classed as inadequately ventilated, need to ensure quantities of DA plus H2 in area are less than 30m3, and quantity of LPG is less than 110 L (approx. 60kg). If quantities exceed this, need to ensure that area is intrinsically safe with no sources of ignition.

  • Quantity of flammable gas in inadequately ventilated storage areas meets requirements. No combustible material in controlled zones.

  • Quantity of flammable gas in inadequately ventilated storage areas meets requirements. If gas dock, or other storage area, is classed as inadequately ventilated, need to ensure quantities of DA plus H2 in area are less than 30m3, and quantity of LPG is less than 110 L (approx. 60kg). If quantities exceed this, need to ensure that area is intrinsically safe with no sources of ignition.

  • Electrical compliance certificate. If there are any electrical items in the hazardous zone, a report from an electrician is required to show that they are suitable for the area.

  • Separation from boundaries. Do not store hazardous substances close to boundary. Separation distance required depends on quantity of substances. E.g. general rule for LPG; up to 500kg is 2m, 2 Tonnes is 3m, 5 tonnes is 5m, 10 Tonne is 7m.

  • Separation from boundaries. Are there hazardous atmosphere zones and are the sources of potential ignition clearly understood?

  • Bulk tanks? Are stationary container certificates in place where required? Check that they have up to date Pressure vessel certificate. Are they up to date and do stationary containers have the correct secondary containment if required?

  • Do employees have the correct equipment/PPE? Suitable clothing is provided. This is an immediate consideration, but it is then desirable to consider the hierarchy of controls under HSE. This may have long-term implications for processes and the nature of work at a particular site.

  • Emergency information folder up to date. Provided for Retails sites however production sites should have them too. Check it complies with contents list. See separate tab for list of contents.
