Helicopter guidelines for land seismic & helirig operations
e. Covered by a roof or tarpaulin to prevent water ingress in secondary
containment, where appropriate for the climate.
f. Be protected from contact with chemicals and not subject to any dying or
painting.
D.4 Drum storage
D.4.1
Storage of helicopter fuel in drums is the least preferred method due to inherent risks
of reduced quality control, fuel contamination and security. Extreme caution should
be used when fuelling from drums due to the possible presence of moisture and/or
sediment. Drum storage and handling should comply with the following:
1. Only epoxy coated steel drums should be used.
2. All drums should be in good condition, sealed at the refinery and with all
required labels and placards attached, including the fill date.
3. All drums will be stored within secondary containment providing full sealing
to avoid small spillage to enter the ground and able to contain the full content
of several drums.
4. Drums will be stored horizontally with the bungs at the 9 and 3 o’clock
positions, with the bung end tilted slightly lower than the opposite end (nonopening),
to prevent moisture/rust formation inside the bung end of the barrel.
5. If exposed to weather and there is a need to have a drums in vertical position
(eg before use), drums should be kept at a slight tilt to avoid rainwater build-up
within the rim.
6. The drum should have been filled within one-year prior to use.
7. Helicopter fuel drums will be stored separately from other types of stock.
8. Provide sufficient supports beneath the first tier of drum stock to prevent the
drums from settling into the soil or resting in water puddles that may cause
corrosion.
9. Chock all drum stocks on both ends of the stack to prevent them from rolling.
10. Contaminated, suspected, or substandard drums will be rejected, labeled
and quarantined separate from acceptable stock and their contents will be
disposed of in an acceptable manner. This will include drums that are used for
collecting the fuel drained for sampling purposes. The standard marking for a
contaminated drum is an “X” marked on the bung end.
D.5 Fuel transport to & storage at remote forward staging
points
D.5.1
D.5.2
Where flight operations need to be conducted a significant distance from base camp
or other bulk fuel depot, forward staging of fuel can be very efficient in reducing flight
time and hence exposure.
Fuel can be carried to forward staging depots in drums or small (heli-portable)
bladders.
1. Preference is to only use drums as received from the refinery.
2. Re-use of drums will be subject to approval from the local Aviation Advisor.
3. Filling of small bladders or re-used drums should be performed with exactly the
