I know Jason  drachoo won the blue for the emotion challenge at one of these races and I'm curious if he can validate this article. It seems that the dust is pretty fine and will damage your equipment if to close to the action. If it can do this to a sealed lens and camera, imagine what its doing to your lungs!! |

i have always wanted to photo one but i have been afraid of exactly this.
if i were ever to, i'd have a long lens and stay far enough away, but i guess that's not even good enough.

You can trust what Roger writes. The guy *know* his stuff.

I went to one last year. As long as you don't get in the spray or have the color thrown directly at you, it no worse than being in a dust storm. I'd avoid changing lenses while in a cloud of it as well.

It's cornstarch. |

I took the strategy of using my 100-400 to shoot telephoto and stay away from the clouds. However, I did get plenty of dust on my camera. I'll have to take a close look at the lenses to see if I see any signs of this.
It did cause a little coughing too. I was curious if I'd see people with asthma flares, but I didn't come across anybody. |

Is it OK to breath cornstarch? Not according to the Material Safety Data Sheet.

Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get
medical attention.
Serious Inhalation:
Not available.
It's an irritant. These things are done in big open spaces where you can easily get to fresh air if needed.

From the Engineering Controls & PPE section of the MSDS
Engineering Controls:
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal Protection: Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.
Exposure Limits:
TWA: 10 (mg/m3) from ACGIH (TLV) [United States] [1999] Inhalation Total.
TWA: 10 (mg/m3) [Canada] Inhalation Total.
TWA: 10 (mg/m3) from NIOSH Inhalation Total.
TWA: 5 (mg/m3) from NIOSH Inhalation Respirable.
TWA: 15 (mg/m3) from OSHA (PEL) [United States] Inhalation Total.
TWA: 5 (mg/m3) from OSHA (PEL) [United States] Inhalation Respirable.Consult local authorities for acceptable exposure
limits.
I'd stay away. |

| I run a lot of races, but won't go near a color run. I wear half a fortune in electronics when I run and I have no desire to trash any of it. |

I got some magenta dust in my lens at one of those runs last year. However it was an inexpensive lens and the fine dust doesn't affect my photos one bit. I was right in the middle of the dust cloud, getting some fun pics.

When I was a kid, my parents couldn't afford sand for a sand box for me to play in, so they got me an asbestos box instead.

That's sweet! All I got as a kid was a mercury filled swimming pool. It sure made floating easier.

Just because were teammates doesnt mean you can hijack my thread like you do everyone else's
BTW did the mercury cause any long term side effects?? |

My wife's parents, both teachers, gave her mercury to play with from school supplies.
In Canada, teachers are VERY well paid, and so it is extremely difficult to get accepted into Teachers' College. Only people with the highest university averages make it. As a result, the ones who make it take few or no science courses, because those courses require more time and generate lower grades. Not a good recipe to be accepted into teachers' college. So in Canada, there are a lot of Artsy Fartsies teaching science courses.
My wife's brother, another Artsy teacher, teaches a computer class. At least he was at the top of all of his Arts courses in university, thank goodness for that. He couldn't tell you the difference between a bit and a byte.
ETA... She's an epileptic.., a connection? Who knows? >:-(
ETA #2, my dad was a university science professor, he gave me mercury to play with, but told me how it could be absorbed through the skin, and was toxic, I was not to touch it, and it only came out when he was there. My wife and I are the same age.

As you can see from my profile picture, I turned out pretty normal.
But to keep it this on track... I would love to shoot one of these events, but I don't think I would have the balls to risk my gear.

I think a waterproof housing is the way to go.

Given that this reportedly penetrates "weatherproof" seals I think the other direction is the way to go ... :-)
BTW: I think that Material Safety Sheet info may be irrelevant, since corstarch is white -- who knows what the colorants are doing to people's alveoli ...

geez, nobody told ME it was toxic. When a mercury thermometer broke when I was young (a loooong time ago), my brother and I were given the little balls of mercury to play with. We batted it around - and it got smaller and smaller. Thinking back on it, we probably invented "Pong" long before Atari did. |

| My dad (a science teacher) used to keep a pint bottle of mercury on his desk, so he could casually ask people to hand it to him and see their reaction when it doesn't move ... ;-) |

Weatherproof and waterproof are two different things. If water isn't getting in, Dust isn't. |
