epoxy resin reaction

But, only 2% will have a reaction to eveb the "bad" woods. I've done several projects with Cocobolo (4 star rated) and never had a problem. Even my last project (rolling pin) was on the lathe where when sanding you get all the fine dust. I didn't even bother putting on one of my 3M dust masks.

Eye contact
Can cause eye irritation. Symptoms include stinging, tearing, redness, and
swelling of eyes.
Skin contact
Can cause skin irritation. Prolonged or repeated contact may dry the skin.
Symptoms may include redness, burning, and drying and cracking of skin, burns and

Ingestion
Swallowing small amounts of this material during normal handling is not likely to
cause harmful effects. Swallowing large amounts may be harmful. This material can get
into the lungs during swallowing or vomiting. This results in lung inflammation and
other lung injury.
Inhalation
Breathing of vapor or mist is possible. Breathing aerosol and/or mist is possible
when material is sprayed. Aerosol and mist may present a greater risk of injury because
more material may be present in the air than from vapor alone. Breathing small amounts
of this material during normal handling is not likely to cause harmful effects. Breathing
large amounts may be harmful. Symptoms are not expected at air concentrations below
the recommended exposure limits, if applicable (see Section 8.).
Aggravated Medical Condition
Preexisting disorders of the following organs (or organ systems) may be
aggravated by exposure to this material:, respiratory tract, skin, lung (for example,
asthma-like conditions), liver, central nervous system, male reproductive system,
auditory system
Symptoms
Signs and symptoms of exposure to this material through breathing, swallowing,
and/or passage of the material through the skin may include:, metallic taste, stomach or
intestinal upset (nausea, vomiting, diarrhea), irritation (nose, throat, airways), central
nervous system depression (dizziness, drowsiness, weakness, fatigue, nausea, headache,
unconsciousness) and other central nervous system effects, loss of coordination,
confusion, liver damage
Target Organs
Overexposure to this material (or its components) has been suggested as a cause
of the following effects in laboratory animals:, mild, reversible kidney effects, effects on
hearing, respiratory tract damage (nose, throat, and airways), testis damage, liver damage,
Overexposure to this material (or its components) has been suggested as a cause of the
following effects in humans:, mild effects on color vision, effects on hearing, respiratory
tract damage (nose, throat, and airways), central nervous system effects
Carcinogenicity
There was no increase in cancer in rats exposed to styrene by inhalation.
However, there was an increase in lung cancer in styrene-exposed mice. The relevance
of the mouse lung cancer to humans is uncertain. Styrene did not cause cancer in mice in

Chris,
Cool! However, I sure hope no one from NIOSH sees that thing! At least I didn't have to worry about any agency issues with my steamer - I doubt the state fire marshals division of boilers would be too concerned!

Fair enough Pete - I poked at your steamer, what goes around, comes around!

Straight from the Brunstucky Skool of Cobble:

SNobsessed wrote: I decided to make a fresh air hood. I used an air pump salvaged from an air bed. Used a sump pump hose & an old welding helmet. An old coat made a skirt, some duct tape, & it is operational. Total outlay $6.

Chris,
Pictures? I've got to see this thing!

i apply a lot of lotion(gold bond) to the areas on my face and arms that might become exposed to to whatever chemical i'm working with that day. they used to make a product called liquid glove but i can't find it anymore, that was perfect. and like at the hospital wash frequently.

morfoot,thats exactly what my face looks like right now lol!thanks guys for sharing all the great info,i knew i would get a good response.little scared about the rest of the project.i got a long way to go and thousands invested.it makes me sick thinking about giving up.one more try with full face respirater,if that fails someone could end up with a great project on the cheap.

Matt sounds like it's a onesie overall for you with hood,don't buy cheep they won't fit or will leak

Be careful guys......this is one I use here (its the hardener)

Ha, good story on the poison Ivy Joe. I'm just the opposite on that, used to be covered head to toe as a kid. I still get it every year because we camp so much but the outbreaks are not nearly as bad.

Now as for epoxies I think you guys are on to something because for about a year I've been having to take Benedril every day to clear up spontaneous rashes on my arms ( I've recently switched to Claritin so I don't fall asleep at my desk). The only thing I think I could contribute this to is the epoxy finishes I'm using on the Hurricane. I'm quite careful and always wear gloves and respirator but it has to be related to the epoxies as I think we've eliminated every other possibilty we can think of. Alergies are a very aggravating issue to resolve.

Good tip- never thought of that!

Ive never had a reaction to epoxy, but have heard allergies can develop after prolonged exposure. I really feel for you guys- Im not sure what I'd do if I couldnt work with the stuff anymore... Im hoping to have a lot of projects in my future! Maybe I should start to invest in some more extensive PPE.

The reactions you guys are describing do sound like reactions to something in the resin but I wanted to bring up something else that could a trigger or catalyst here. LATEX. Latex allergies have become more and more popular especially from those who use latex on a daily basis. Here at the fire department we have gone away from latex products all together. Just something else to think about.

I've had reactions from time to time. The lab I'm in has lots of resins, paint stripper, adhesives ect...

I've had more respratory reactions than skin though.

People don't know in but your skin IS the largest organ.   

Yes big time reaction..... After working with the stuff for 8 years on a daily basis I finally became allergic to a common resin we use in the shop for standard wet cloth lay ups. I determined the culprit was the catalyst added to the base that I developed a reaction to. I've become so sensitive to it that if I get within arms reach I end up looking like the below picture.
I normally use a full face respirator before I even grab the cans to measure out and mix up the stuff. One day I was getting ready to go home for the weekend when a guy asked how fix a fiberglass engine fairing that I helped develop a repair for. I demonstrated how to dip the brush into the resin and stretched my arm as far as it would go (didn't have my respirator on) and showed the guys how to lay it up. They looked at me rather odd as I keep my arm stretched out the whole time. MY eyes itched the whole rest of the day and when I woke up the next day I looked like THIS!






So to answer your question YES! It can happen just from the vapors coming off the stuff!

Mine was in odd places. I got it once on the back side of my leg around my knee and the other time was on my forearm. Never got any inside my paints though.
