Please do not get me wrong but I feel that it is important to know how Sodium hypochlorite can affect us, the fact is that it is a dangerous chemical and should be treated with respect, in this link you can see some details http://en.wikipedia.org/wiki/Bleach such as
The OSHA highest allowable peak concentration (5 minute exposure for five minutes in a 4-hour period) is 200 ppm
12.5% hypochlorite = 125,000 ppm diluted 50/50 (water/ chlorine) means that our mix contains 62,500 ppm a 25/75% mix contains 31,250 ppm (parts per million)
In Australia the maximum allowable exposure limit over an 8 hour period is 1.0 ppm
most swimming pools are around 2.0 ppm
The health effects at the levels that we use are serious and real!
Please do the right thing, resporators, clothing etc. please take this chemical seriously. A lot of newbies splash this stuff around like it's water, it is not. and potentially can kill
The reason why I mentioned this is that the other day I copped a big bad nose and lung full of this stuff, and the experiance got me worried, it took over an hour for me to start to feel normal and settle down
I started to question the wisdom of using this stuff
It scared me!

Yes, wear gloves, safety goggles, and 3M filter masks with 6006 or 6009 filters.
And the low ballers should think twice about giving roof cleaning away ? Perhaps they will remember the whole subdivision they did for 150.00 a roof, when they carry Oxygen around the rest of their life
When I first started out I did a roof while I had a leak by my nozzle. The love dripped down my arms and I didnt pay too much attention to it. Then it burnt the crap out of me. Ever sine them Ive been very cautious and treated the love with respect.

Ditto. First roof i ever did, poly gun was leaking and SH dripped on my forearms for about 3 hours. Permanently scarred my right forearm. To this day, the burned skid marks are still visible.
