Militia's abilities

[clinkz]

Hello guys,

1/ " [cancel Disaster]. "
That means I can discard any cards either from my hands or in play or even both of them, right ?
Is it true that I can cancel the Disaster once it is played even it's not my turn ?

2/ " [count 1-Hand Item as 2 Hands] "
So if I equip Survival Tool (+2 bonus) and I use 2nd ability, it gives me total of +5 and my hands now are occupied. Then I use Arm-Y Surplus to get an extra hand, in that case, I equip 1-Hand big item, does that conflict with "2-Hand Survival Tool" ?

Thanks
