Victoria University Antarctic Research Expedition Science and Logistics Reports 1976-77: VUWAE 21

F. Recommendations

F. Recommendations

(a)

It is suggested that tests be made on the strength of fabrics currently being used on Polar tents. On this expedition two such tents were badly torn by winds gusting above only 60 - 70 knots at 2 metres. This seems to be an unacceptably low wind speed and obviously could lead to dangerous page 22 situations. Both tents were well pitched.

It is possible (although it would be a coincidence) that these two tents have been on Erebus and have had their fabric weakened by the acid volcanic gases. Flags placed on the main crater floor in 1974 were visibly corroded after 3 or 4 weeks. Easterly and southeasterly conditions which are common at the summit almost invariably envelop the camp in vapours from the Inner Crater. There have been a total of at least 2 weeks of such conditions, in which tents have been pitched at the summit camp, since 1972. It may be advisable to keep a log of the particular tents used on Erebus.

(b)The guy ropes on the Italian tents should possibly be replaced with stronger cord, although this will not reduce the possibility of abrasion.
(c)Toboggan windscreens should be braced to prolong their life.
(d)Parties who will be lashing sledges to helicopters should be familiarised previously, possibly at Tekapo, with the loading, especially of combination [unclear: Name]
(e)To add one more possibility to the continuing debate on "carbon monoxide" poisoning, it may be that red lined tents present a greater risk for such poisoning because red and orange flames from a faulty primus are not so apparent. Event 36 experienced a minor case of poisoning from a new primus that appeared to be in good order.
(f)Several of the VUWAE primuses are getting old and should be replaced before the 1977/78 season.
(g)As has been recommended in the past, sledge keels and foot brakes should be considered essential parts of a sledge.
