This may be a bromine analogy to the chlorine generation when bleach, hypochlorite and chloride in alkaline aqueous solution, is acidified by even a weak acid (eg. carbon dioxide even). If the pool "bromine" is a bromination agent such as N-bromohydantoin or a similar N-bromoamide and the Simple Green contains a bromide quaternary surfactant, hexadecylpyridinium bromide or cetyltrimethylammonium bromide, and some weak hydrogen ion donor, it could be that bromine is generated. To loft it as a smoke seems to require some heat generation as well.

If I was doing a crossword puzzle and the clue was "really irritating red smoke", seven letters with given "m" in the middle, I'd try bromine first.

OK, class.  Below is the Google article about a mixture that created  "a red smoke."   The two chemicals were Simple Green and some kind of bromine pool chemical.  Could that smoke have been bromine vapor?  Or what?

 

Simple Green is a couple of detergents and 2-butoxyethanol (at least this is what it is this week since it changes a lot).   Any ideas on what was happening here?

According to a department spokesman, the crew was dispatched to the 5400 block of Beaverkill Road in Columbia at 8:35 a.m. after members of the cleaning crew accidentally mixed Bromine and "Simple Green," an all-purpose cleaner. The spokesman said the accidental mixture caused a red smoke, which was inhaled by one of the cleaning employees. The employee was taken to Howard County General Hospital as a precaution, according to the spokesman. The incident caused a road closure for over an hour. The incident was cleared by 10:09 a.m., according to the department'sTwitter account.

If the power's out, ya'll should be out of the building anyway or at least not working with chemicals.  And if your Fire folks are like my Fire folks, they have electronic access to multiple (M)SDS resources on the rig, if it's an emergency causing the power outage.

 

I encourage my folks to have paper copies of the (M)SDS for the chemicals they use all the time, every day.  And paper copies of the half dozen or so most hazardous materials they work with.  Typically, it ends up being maybe 12 or 15 hardcopy (M)SDS.  Then to place a link on the shared computers to the (M)SDS database.

 

Sez me!

Doesn't the requirement for (M)SDS access even during a power outage by default require paper copies? Or am I missing something?

Our MSDS FAQ has not yet been updated for GHS, but these two requirements do not appear to have changed.

The OSHA requirements of (M)SDS availability are not changing.  You can make them available on line, as long as there are no impediments to access.  For example, no individual who ought to have access should have to go to a supervisor's office or seek help or permission from another to get on line and review one. (This is paraphrasing an OSHA representative presenting on the Hazcom 2012 implementation this week at the AIHce in Montreal.) In addition, you must have some sort of backup function to provide immediate access to (M)SDS in the event of a power failure, etc., when access is needed.

 

On the issue of whether it would be acceptable to make available an Aldrich (M)SDS on sodium hydroxide when your NaOH is from Fisher, my less authoritative response is that my impression of the HazCom 2012 changes would make that UNacceptable.  But others may read it differently.

I am in the process of deciding whether to recommend that my college pay to subscribe to an (M)SDS service (ChemWatch) or download and store my own repository of (M)SDS pdf's.  I'd be grateful for your thoughts about the proper way to manage access to (M)SDS by employers.

  • Do we have to have paper copies storied in a physical shelf location, or is a site license to ChemWatch OK.  Can I simply maintain an easily accessible link to a folder of downloaded pdf's on our server?
  • If I have a bottle of sodium hydroxide from Fisher and a downloaded (M)SDS for NaOH from Aldrich, does that meet the OSHA requirement?
  • Are others using ChemWatch, and is it a good system (worth the money)?
  • Are there other considerations I should be aware of as I weigh the $2000 yearly fee against the tedium of maintaining the system myself?

Thanks for your thoughts!
