Tri-Flow has a HMIS Code of "2" (moderate) and the tests were with exposure of 4 hrs and I "assume" at a specific concentration. ChainJ is zero. Ethanol is also a systemic neurotoxin (91% HMIS of 1 - slight. Anyone ready to adhere to the Word of Wisdom? I gave it up years ago.
Managing OSHA requirements can be painful, hence the media reports of over burdensome regulations. Basically don't assume anything you do at home or your own can be done in the shop without training, safety considerations, and proper marking of anything that comes in a container. One quick technique is to capture the legal warnings off of anything commercial you bring in the shop (check the manuals) and go from there.

Hi all, first post. 

Actually, looking at the MSDS on the tri-flow site (, it does mention neurological side effects:

No ingredient in this product is an IARC, NTP or OSHA listed carcinogen.
Reports have associated repeated and prolonged overexposure to solvents with permanent brain and nervous system damage.

I googled it and came up with this MSDS sheet. Here are the side effects below.

I am reporting observations from some of our mechanics, who experienced shortness of breath, numbness, feeling dizzy, and increased bruising on their skin from getting it on their hands and inhaling it.  We've encouraged nitrile gloves and increased ventilation when using all petroleum-based lubes since then, and also switched to a lubricant like ChainJ that seems to cause few if any side effects.

The MSDS states the long term effects of overexposure below, which are in line with side effects of other
chemicals like pesticides:

SKIN                                        CAN CAUSE DEFATTING OF THE SKIN,
                                            WHICH MAY RESULT IN SKIN
                                            IRRITATION AND DERMATITIS

Before everybody gets all bent out of shape about Tri-Flow being a "systemic neurotoxin", can anyone site scientific literature that backs up this claim?
I just did a check on Google Scholar any came up with nothing...Or does Google cause cancer as well and therefore is in on this conspiracy?

Triflow is also a systemic neurotoxin that wrecks both nervous system and brain. Really bad stuff

1) Chemical-soaked rags are stored in metal fireproof containers
2) Chemicals are kept at least 4 feet high away from children
3) No smoking within 10 feet of the shop
4) Fluorescent lights and radiant heaters are caged to prevent them from being struck by bikes or random
flying parts (our back room is only 7 feet high)
5) Welding is done strictly outside the shop, no youth allowed.
6) We have a fire extinguisher in the shop, and try to minimize clutter.
7) I keep a well stocked first aid box because people are always stabbing themselves with cable ends, chainrings,
tools, and the like.
8) Encourage volunteers to get tetanus vaccinations and boosters.
9) Keep the shop stocked with nitrile gloves to prevent lubricants and penetrants from making skin contact-
TriFlow is particularly absorbent, and will cause capillaries to break in the hands. We switched to ChainJ for this reason.
10) Water cooler and electrolyte mix, working inside or in the shade, and shorter shop hours during the summer
to prevent heatstroke and dehydration.
11) Possibly making our core volunteers take Basic First Aid and CPR, although we have enough first response people floating around the shop (on-duty cops, nurses, PAs, etc.) to be sufficient.
12) All electrical and water lines are marked- electrical lines are run down from the ceiling to prevent trip hazards.
13) Encourage closed toe shoes, goggles and masks if filing, sanding or otherwise running power tools.

That's about all I can think of for now.

Hey All,
I just went to a day long seminar on Human Resources where they spent some time talking about OSHA.  From what they said at the seminar OSHA can come in at any time and audit your shop.  Apparently if they find violations they can fine the shit out of you.  Here are some things I learned and remember this was 20mins of a day long seminar, there are week long classes on this stuff.  This is a very short list.
  • All chemicals and solvents should have warning labels on them clearly stating what's in them in multiple languages
  • You should not keep aspirin, ibuprofen, neosporin or any other pharmaceuticals that someone could potentially have a reaction to in your medicine cabinet
  • Exit signs should be on all doors.
  • There should be no trip hazards.
  • Your staff needs to go through trainings on such things as how to use a ladder.
This list is nowhere close to comprehensive but I'm going to be looking into this more in the coming weeks and months.  We've been around for almost seven years now never had a serious accident and I want to keep it that way. 

What are you guys doing to keep your shops safe and maybe even OSHA compliant?

Ride On!
