Nate, I read your full thesis and I thought you did a good job, and covered about everything for my commercial size biomass cooking stove. I would like to include your paper with my request for coverage to the underwriters if that is OK? Thanks, Lanny
----- Original Message ----- From: Nathan Johnson To: [email protected] Cc: Christian L'Orange Sent: Wednesday, March 13, 2013 2:54 PM Subject: Re: [Stoves] Hazards for Institutional Biomass Cooking Stoves Hi Lanny, The stove safety documents on the PCIA website include a description of stove-related hazards, guidelines for safer stove design, and test protocols with metrics to rate stove safety. The protocols were designed for testing in the field with minimal equipment. This acknowledges the financial and technical constraints of small-scale manufacturers in developing countries. That said, most of my safety testing is done in a laboratory, as I expect is common with others on the discussion list. Please let me know if you have any questions. Durability testing is not covered in my earlier work. I suggest you contact Christian L'Orange at Colorado State University regarding durability testing (e.g., 10. Structural integrity, an example from your initial inquiry). Thanks Christa for the reference!

Hot coals spill out, roll out or puff out igniting combustibles. 8.. Flame containment, not enough distance to combustibles. 9.. Hot stove surfaces, not enough distance to combustibles. 10.. Structural integrity, falls apart, burns up, door fails, legs breaks off 11.. Sharp edges that can cut or scrape 12.. Sparks out the exhaust that could ignite combustibles 13.. Volume of fuel in a batch could be a factor. example 12 kg of wood in a wood space heater verses 1 kg of wood in a cook stove. 12 kg has the potential to do more harm than 1 kg. 14.. Pot spill from difficult access. Like lifting a pot from a sunken pot stove. -------------- next part -------------- An HTML attachment was scrubbed...

It is available on the legacy website of PCIA on the bottom of the page http://www.pciaonline.org/testing. It actually operationalizes most of the issues you are raising. regards Christa Am 12.03.2013 um 20:45 schrieb Lanny Henson <[email protected]>: I need liability insurance for an institutional size wood cooking stove that I would like to market in the USA as well as outside the USA.
