Does anyone have any info related to the proper OSHA/NIOSH FACE MASK one should use to protect against inlhaling fumes generated by bullet casting. I realize the simplest solution is to cast outdoors but I want to be extra cautious. Often the wind just blows it back in your face.
Thank you!!
Protection from lead fumes

the fumes you see comming off your melted lead are not lead. i dont know how you would get your melt hot enough to vaporize lead. what you are getting is impurities burning off. takes a lot of heat to vaporize lead. argie1891
if you think you have it figured out then you just dont understand

Ditto what argie said. all of the stinky stuff is impurities.

you could probably get a small fan and let it blow away all the stinky stuff even if the wind quit blowing.. argie1891

I think you should worry more about the mercury vapor fumes in the new Al Gore's squiggly light bulbs thrust upon us should one burst. Everyone should just call hazmat when the burn out, they don't last long either.

Use a half mask with HEPA filter. North Brand works great and cost is around $40. It's more important to protect young kids and should be keep away. The fumes will settle around the area. Needs to be keep clean. A HEPA filter to draw fumes from melting pot works great, just make sure it draws enough air flow to filter out lead fumes from the air.
Oh wash your hands and don't eat while doing this. I been working removing lead paint during maintenance of our facility and have learn a lot and had yearly blood test that proves things can be done safely.

Removing lead paint will generate lead DUST, not fumes. Lead dust from old dry lead paint IS toxic, and masks are in order when working around it. But you cannot get lead hot enough with any commercial bullet casting lead pot to cause the lead to gas off. The melt would probably have to be just about glowing red before you could generate any lead fumes.

I would never tell anyone not to use precautions when handling lead, dust masks etc are always good ideas and it pays to be saftey minded. That being said....I have worked small construction for over 40 years with a lot of restoration work and been casting for 35 years. I've torn out more laed containing substances and sanded more old lead paints than most people can imagine and I do have blood lead tested periodicaly...it's never been a problem at all and my last test a couple months ago was virtually immeasurable.

I'll add that in order for any respirator to work properly, it needs to be fit tested.

if i may add something from the netherlands i know some old casters they do it for over 40 years now. (and nobody has knowledge of 308 casting) there blood was tested on lead but finding no health issues, it was no problem! at the other side of the coin someone how has never casted a bullet, but lives his entire life i a big city(like amsterdam). had more lead in his body than a lead caster both persons are in the age of 64 and 66 and friends but it is true, take care with lead dust and murcery. even on a stove i can not get it red hot, only in my fireplace. so rest well and have a lot of fun of casting with the best regards parkerhale

Like most of the replies, it is minute to what you are being exposed to, mostly because most of us casters have never had any problems, even those who had blood tested.
The 'green' society is grosely over-emphisizing lead exposure as severly dangerous, like if a city slicker looked at a lead ingot laying on the downtown sidwalk everyone in the area would have to be decontaimated and the whole area quarantined! :)
Like 'green onions' says he works with lead paint, I worked around lead in a factory for 30 years and most no one ever had any problems. If one did have raised levels of lead, the body natually washes it out with no affects in adults, but is worse for children. I'd rather drink plenty of liquids as a precaution for a few days after sweating over a few casting sessions.............Dan

Exactly which brand of “liquids” do you prefer after a few casting sessions - medidinal purposes, of course.....

Your local brewery's beer will have the best natural nutrients. Other diuretic beverages containing caffeine will do the trick, so brew up that morning coffee stronger. The tea drinkers can use the ‘detox' variety of green teas which contain natural diuretics such as dandelion, nettle, and fennel which surprisingly taste good.
Sit down and eat a watermelon. Include asparagus and cucumbers in your diet. For a big purge with beer, use the ‘light' variety containing more anti-oxidants and less carbs. Once engaged into the beer purge the mask concern will appear quite frivolous........Dan

The Al Gore BS Mark III mask is the best protection here, if you can find one.

And you have never worn any type of protective device all these years while doing this type of work?

For th vast majority of the years in construction Paul....no....there was very little thought given to those things 40 yrs. ago. We did sometimes wear a dust mask but that was all. Like I said I would never advise anyone not to wear protective clothing etc. but I think the idea of getting high lead levels from casting is a bit over blown. You're more likely to injest lead from your brass tumbler than from casting.

Lead poisoning is very difficult to get. Think about the tens of thousands of people who have worked with lead for years without a problem like guys in radiator repair shops, plumbers and old timers in printing shops etc. The safety nazis have gone way overboard with this like many other dire sky is falling predictions. By the way, the word plumber is derived from the latin word plumb which means lead. The Romans had lead issues because they ate off lead( pewter) plates. You are not likely to get lead poisoning from lead water pipes as the water seals the inside of the pipe in about one hour after initial installation. People have had miles of perfectly safe lead pipe torn out for no good reason. But it makes great bullets.

I have handled and melted lead for about 50+ years, not counting my early fishing days when we used to bite crimp-on sinkers and then nobody even knew what lead poisoning was. In December I will be 68 yrs old. After seeing this subject come up over & over again I had my Dr. do a blood test. She said the results were “normal". I asked what that ment & she said I didn't have a problem & to stop worrying about it. Having said all that I wouldn't advise anybody to not take precautions. If wearing a mask makes you feel better, by all means do it. Ervin

The solubility of metal lead is so low that you almost cannot get lead poisoning from handling or exposure to it. Tetraethel lead such as used to be in gasoline is another story. There is a tale (told to me by my old quantatative analysis professor) about a little old lady who was so afraid of osteoporosis that she took about eight calcium tablets a day. Because egg ranches tend to be near highways and the fumes from the tetra-ethyl lead laden exhaust were around the chickens all the time; the birds picked up the ionic lead and incorporated it (a divalent cation like calcium) into their egg shells. Because egg shells are almost all calcium the NATURAL FOODS people who made the calcium tablets just took egg shells, washed and cleaned them, crushed them and added a binder and formed them into tablets and sold them as a calcium supplement. Because the chickens had incorporated the lead -from the gas fumes- into the material of their egg shells, and the LOL had eaten too many of the tablets she finally developed lead poisoning, and eventually due to her advanced age and other medical problems finally succumbed to it.
As has been pointed out you cannot get your casting pot hot enough to vaporize the metalic lead. The only way you are going to introduce enough lead into your system is to ingest it orally. Don't smoke or eat while casting, and wash up thoroughly before you do, and this won't be a problem.
The enviro-nazis are so concerned about lead that they won't even let cinders from the pits around here which shooters have been using be put on the roads during the winter. Of course by RECRA standards those same roads, and any street or highway made from or with asphalt are by definition ILLEGAL TOXIC WASTE DUMPS. They will not allow the deposition of material lightly contaminated with a heavy metal onto an illegal toxic waste dump which is defined as such by its concentration of heavy metals, most of which are much much more toxic that the dreaded lead.

For lead to vaproize it has to heated to in excess of 3000 degrees. that's not going to happen at home with a typical electric lead furnace or propane or natural gas heat source.
