Discussion Overview

The discussion revolves around the hazards associated with Aluminum Potassium Sulfate, particularly in the context of a school project involving crystal growing. Participants explore safety concerns, potential irritations, and the implications of handling the chemical, especially for students with conduct disorders.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks detailed information about the hazards of Aluminum Potassium Sulfate, particularly regarding skin contact and ingestion.
  • Another participant suggests that the substance is generally safe, noting it may cause slight skin irritation similar to kitchen salt, and that washing hands should suffice if any symptoms arise.
  • A different contributor mentions its historical use as a styptic pencil for stopping small cuts and implies it is safe for student experimentation.
  • Some participants express skepticism about the safety documents, suggesting they may overstate risks, while others share anecdotal experiences of its safety.
  • Concerns are raised about the chemical's association with aluminum salts and Alzheimer's disease, although this is presented as a potential justification for avoiding its use rather than a definitive hazard.
  • One participant references a specific incident in the UK where a large quantity of the chemical was accidentally dumped into the water supply, leading to illness, indicating that while it is generally safe, there are notable exceptions.

Areas of Agreement / Disagreement

Participants express a mix of views on the safety of Aluminum Potassium Sulfate. While some argue it is safe for use in educational settings, others highlight potential risks and express caution, particularly in light of safety documentation and past incidents. No consensus is reached regarding its overall safety.

Contextual Notes

Some participants note that the health aspects of Aluminum Potassium Sulfate may not be thoroughly investigated, and there are references to varying interpretations of safety data. The discussion reflects uncertainty about the implications of handling the chemical in a school environment.

Is anyone familiar with Aluminum Potassium Sulfate? We have a "crystal growing kit" at school, and this is the chemical used to grow the crystals. Since some of my students have conduct disorders, I wanted to know more about the chemical before I permitted the project. I read the hazard codes, but I'm looking for a more "straight dope" description of the hazards of this chemical. What exactly happens if you touch it? If someone licked a crystal, would it actually be necessary to call poison control? (I'm not going to let anyone lick it. In fact, I'm almost certainly going to prohibit this project. I'm just looking for some justification, if it exists.)

Fishing rod: google "Aluminum Potassium Sulfate MSDS"

Fish: this is quite safe substance. Some may find it slightly irritating to the skin, but the same can be said about kitchen salt. Just washing hands should be enough in the case any symptoms appear (which is as far as I remember quite unlikely, I did similar lab eons ago, I think the effect I remember was that the skin got a little bit dry and harsh). No reported toxicity, so even if they swallow some there should be no problems. Compare http://en.wikipedia.org/wiki/Alum - plenty of cosmetic/culinary/medicinal uses.
 
Well, I've heard that you can keep your cat from eating your parakeet with it. (starts at 2:20 min.)

Seriously though, it's a pretty safe chemcal... one of the few remaining ones that students can play with. It used to be formed into a stick and sold as a styptic pencil. Cut yourself shaving? Press the pencil against the cut and it stops bleeding immediately (for small cuts).

If you want an excuse not to use it, you can always say that aluminum salts are implicated with Alzheimers.
 
Quote from Flinn's MSDS:

Call a physician, seek medical attention for further treatment, observation and support after first aid.
Inhalation: Remove to fresh air at once. If breathing has stopped give artificial respiration immediately.
Eye: Immediately flush with fresh water for 15 minutes.
External: Wash with soap and water.
Internal: Give large quantities of water. Call a physician or poison control at once.

Would you dare to try to guess what substance requires such measures?

Substance not considered hazardous. However, not all health aspects of this substance have been thoroughly investigated.

Would you guess what chemical they described this way? (Same First Aid Measures listed, seems like they put exactly the same information everywhere.)

They sell to schools, their MSDSs are there to cover their back.

Edit: I see chemisttree did exactly the same, just faster :smile:
 
It is used in water treatment plants for clarifying water. At low concentrations it is ok but some accidents have occurred fairly recently (in Britain)where huge quantities were dumped in the water system and illness occurred in people drinking the tap water supplied.
