ok so im an explorer and over and over again in drills we have kids jumping off the truck masked up either on air or not and lets the mask fog up. i usually let my mask hang down with the regulator attached is that wrong?
You definitely don't need to be masked and on air when you jump off the truck. You're wasting air. Look at the structure, get your assignment, look at the structure again to discover points of ingress/egress. Tese things are hard to do when you're wearing a mask.
I use one of my coat straps to secure my mask to my chest. I've let it dangle at the end of the hose which resulted in dust, snow or other kinds of crap on the inside of the mask.

OK this was addressed within a month ago. The topic was MASK FOGGING.
I will repost my response. Training creates situations that are not how we operate under emergencies. In FF1 students would put on the Mask and wait around forever for evolutions to start... fogging would occur and the purge valve definately works but wastes air. But since then, I have seen too many near miss situations related to fog and this exact topic and it needs to be clarified by a behavioral modification, ie. training.
I see alot of newer firefighters donning their mask while the truck is going down the road. BAD HABIT By the time you arrive in the winter time, you can't see because of fog, and this hinders your ability to step off the truck safely, locate your tools and equipment, and more importantly, get a good look at the dwelling that you are making entry on.
I also see people standing in personnel staging or RIT who have their masks on? How do you know your assignment is going to need a mask donned? Wishful thinking I guess...
Here is a thought, start training to put your mask on quickly and correctly at the entry door just prior to going in. It should take 15 seconds maxx. This eliminates the trip hazards, lack of communications, and missing any vitally important factors. It also forces you to "slow down" your emotions and adrenaline and actually "see" a good size-up of the dwelling, the fire conditions, allows better communications with your crew, witnesses or victims.
It is amazing what you will pick up while donning the face piece just prior to making entry. Therefore, We use no cleaners, sprays or shaving creams... Fog problem adverted, wasting precious and valuable air resolved and the tip and training technique was free.
The only problem i have is keeping the mask secure while I'm doing exterior operations on drills ( i.e. throwing ladders and etc.) or before being cleared to help with salvage and overhaul any suggestions
For my self if I'm doing exterior ops...drills or fires i will put my mask in a "mask bag" that i have clipped on my backside.
I leave a couple of the straps hanging out so if i need it in a hurry i grab the straps pull and the mask comes out no problem.
As far as interior goes? like "damnthing" stated mask goes on when entering an IDLH atmosphere.
Our masks come supplied with a neck strap, our training has us put this strap on first so we can let the mask dangle from that instead of the air tube. The training also has people turning the mask so that is alwas hangs with the interior against you chest, protecting it from anything falling.
When do we 'mask up' (we call it start-up)? Just before entering the building. As first team in this would mean at the pumper so that you can then grab the hose and head straight in. Our BA sets aren't in the cabin - we don standing at the truck, then head in.
undo your waist strap and strap the low pressure line (with mask attached) to your waist by securing the buckle again. When you need it, release the strap again allowing the mask to come out and resecure the waist strap
