it and How? |
| |
|
|
1. Identify
underground services. Establish a 1.5M
Exclusion Zone around the |
Name |
| Working near |
|
|
identified location where digging is only by hand tools. |
|
| Gas Lines/ |
lack of oxygen |
|
|
|
|
|
|
|
|
|
| Pipes |
|
|
2. Use appropriate
PPE and safety equipment; ensure it is
in good working order |
|
| |
|
|
and maintained and used as per the manufacturers
instructions. Eg. Protection |
|
| |
fire or explosion |
|
from potential Toxic
or Flammable atmosphere generated. |
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
| |
|
|
3. Fire Extinguisher to be on site. |

electricity to be used. |
|
| |
|
|
|
|
|
|
|
|
|
|
| |
|
|
5. Only Licensed Gas Fitter to operate on Gas
Lines. |
|
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
| |
|
|
6. Industry required
Signage, Barriers, Tagging & Permits to be used and followed. |
|
| |
|
|
Eg.
Cylinders to be labeled to eliminate confusion of gases. |
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
| |
|
|
7. Gases to be

|
| |
|
|
|
|
|
|
|
|
|
|
| |
|
|
8. Check records for
type of Gas Fitting System to be worked on.
Eg. A High, |
|
| |
|
|
Stored Pressured System could constitute a danger when
fittings/ components |
|
| |
|
|
are disturbed. |

9. Control
Conditions with constant forced ventilation providing adequate dilution |
inspection |
| |
|
|
|
of gases worked on as
per Manufactures Specifications. |
|
|
where required |

supervised |
| |
|
|
|
11. Remove or Reduce
exposure to Gas. Eg. Turn Off downstream from where |
|
| |
|
|
|
work is to be performed; Isolate Gas by using a blank or
plug or installing a spade/ |
|
| |
|
|
|
disc/shim between 2 fittings; Use a Reverse Flow prevention device;
De-pressurise |
competent |
| |
|
|
or Purge a chamber
using air or an inert gas. |
