INSTALLATION

Gases, Vapours & Mists: All hazardous area equipment for use in flammable gas, vapour or mist environments must be installed in accordance with the AS/NZS 2381 series of standards (until September 2011) and with AS/NZS 60019.14.

Combustible Dusts: All hazardous area equpment for use in combustible dust environments must be installed in accordance with AS/NZS 61241.14 (until September 2011) and with AS/NZS 60079.14.

INSPECTION 

Gases, Vapours & Mists: All hazardous area equipment for used in flammable gas, vapour and mist environments is to be inspected in accordance with the AS/NZS 2381 series of standards (until September 2011) and with AS/NZS 60079.17, the superseding standard.

Combustible Dusts: All hazardous area equipment for use in combustible dust environments must be inspected in accordance with AS/NZS 61241.14 (until September 2011) and with AS/NZS 60079.17.

EPEE can use your inspection records or ours - which are spreadsheet based and can be imported into a database or be formated to use a spreadsheet Ex Register.

If an Ex Register has not already been compiled, it is best practice to compile one with what information exists before performing the inspection. Missing items can be added during the inspection.

This will generate a punchlist - featuring all items for attention. This items will be prioritised as follows:

• A: Fix immediately
• B: Fix within 7 days
• C: Fix within 30 days
• D: Fix at next mainenance opportunity.

During installations, it is usual for a number of systemic errors to creep into the installation.

It is better to find these problems at an early stage of installation.

This can be achieved by having EPEE begin the installation inspection within a few days of the installation begining, rather than at the end of the installation.

EPEE would prefer to assist staff to produce compliant installations rather than publish extensive punchlists.

SOLUTIONS  - NOT PROBLEMS

While the maximum inspection frequency quoted by AS/NZS 2381.1 is 3 years, it is not recommended that such a great inspection interval be adopted.

Where corrosion is an issue (either from the process or due to the proximity to the ocean) a period of 1 year is recommended.

In practice, periods should be set for all other place to 18 to 24 months at a maximum, particularly in harsh environments such as hot, remote areas subject to continual action of UV radiation.
