Yes those are general symptoms. ISO Generally affects the respiratory system and will cause rashes. If you are having reactions to it, I suggest you IMMEDIATELY remedy any problems you have with respirators(And I pray you are using an outside air respirator) and/or other safety equipment.

Also, ISO can soak through the skin just like any other liquid, so wear gloves, and at minimum a tyvek suit.

If you are having shortness of breath or any other respiratory reaction, seek medical attention immediately.

Refer to your manufacturer's MSDS sheet for more info.

In mid-late April, it is more likely a sign of spring allergies. Check that as well.

hazy vision is another sign of exposure be careful not to expose yourself to much to it i have heard of people becoming sensitized to it where much less exposure in the future will cause these symptoms to occur.

I think the following info from OSHA will cover what we are talking about in this topic.

Always wear a mask and you should be fine, as long as you have the right filter. The less exposure that you have the better. Its Safety equipment, USE IT

i believe that the "optical haze" is more due to the cornea absorbing a component of the blowing agent,,,so do a search for "painters halo" or "painters haze" or the like,,,i forget just how i found it,,to learn more,,,(ya see the cornea is like 90+% water and it absorbs the vapor,,i really notice this in confined attics with OC,,,i always wear full face...minimum..
the blurred vision associated with iso exposure is due to CNS depression associated with prolonged, repeated,excessive exposure...and if you got to the blurred vision stage,,you probably are on the oxygen tank,,,,so,,
please be careful..
apply with good safety for you and those around you..
educate yourself,,if you think it doesnt pertain,,,learn it anyway,,,it will broaden your horizens,,and you will use the education at a later date in time..
if you have to ask "should i" you probably shouldn't...
and last but not the least,,,
...tiptoe thru the foam fumes with me....

As far as the MSDS on ISO I believe that to be worst case symtoms. I was spraying and started getting congested with very runny nose and the following morning had a large amount of flem in my throat. Took half a morning to hack up. Went to doc. took a pulmanary test, were you breath in to the tube and they check lung cap. . Also chest xray for fluid in the lungs both came back fine. But the doc. has no knowledge of iso and none in this area do. In conclusion I maybe being a little too careful but I feel I rather no my bounderies be for its to late. Also it appears olger maybe right haveing a fresh air pump in the middle of a midwest field pumping me mass quantities of spring fresh allergies could be the major cause.

Generally we are taught that 5% of the population has an allergic reaction to Isocyanate exposure.And like Olger told me months ago,"you will know if you are sensitized"

Plenty of scary stories out there. Especially scary to the people that have reactions. A night or two of thoughtful google searches and one will discover plenty to be scared s**tless about. I have a sensitivity to Iso in the spray enviornment. Some can't not barely even look at the stuff without reactions. Under pressure a small amount of Iso will "atomize" in the mixing chamber. This atomized content then finds its way into the building envelope as an aerosol. This aresol in very slight amounts now effects me. Sucks for me. With what many consider extreme safety measures I can safely spray in specific settings. I can clean the guns and change chemicals all with no problems. Sadly Im taking a greater risk than most when I do this. Becasue of my previous poor decisions and exposures resulting in a couple different very disconcerting allergic reactions. And most likely because of a genetically pre-disposed sensitivity.
My choice. Mostly I continue because I have discovered that I have more of a "mid level: sensitivity. I never have experienced rashes or extreme occupational asthma. And because as my business grows I have been able to focus more on sales and quality control. Minimizing my spray time. If I was working for someone as a sprayer I would be LONG GONE. Like I said sucks for me.

Everyone so far is right. Key is to watch your symptoms carefully. And just be SUPER CONSERVATIVE with your mask procedures. PPE at all stages. Where a mask with 100 ppm cartridge when changing chemicals and cleaning the gun. Latex/nitrile gloves at all times. Fresh air full mask while spraying or assisting the sprayer. Fit your mask properly. Keep the air pump up wind. Watch out with those solvents, maybe the gnarliest vapor/skin absorbed chemical we use.

You are not being too careful. OSHA requires that sprayers (employess anyways) have CP system tests and chest x-rays.

The lame part about allergic reactions is that no reaction or a mellow reaction one day or year can just plain turn into full respitory shut down the next. Bee-stings, peanuts and chemicals etc. Ive never gone into anaphlatic when I have been stung. I barely have more than pain and some swelling but it could happen. Chances are it won't....but it could.
