Safety Accident Analysis - How one of the most benign mixes we work with caused a fatality. There are additional comments from an email by Kurt Medlin. This was reposted by permission from the PGI bulletin and credit is given at the front of the article.
Stainless Steel Bowl Ignition. Never use stainless steel bowls when working in the sunlight. If you have a live composition in the bowl, it can ignite. This link is to a short video by Blake Stoltz. It shows an ignition of some BP after only 30 seconds in the sunlight. In the test previous to this video, the ignition occurred approximately 5 seconds after setting the bowl in the sun.
