During charging, most batteries will off gas hydrogen, making adequate ventilation and the elimination of ignition sources critical attributes of the charging area. Data from the battery manufacturer should be consulted to determine appropriate…
Many accidents reported from paper mills have much in common with this incident. Microorganisms in the process water with pulp produce hydrogen gas that mixes with air to form an explosive atmosphere. The ignition source is typically sparks…
Although the preparation-for-transport procedures were done the same way they were done for previous outreach programs, this time it proved to be a different situation. It is not clear what caused the ignition of the first balloon, which then set…
Safe storage and transportation of balloons filled with a hydrogen-oxygen mixture is a very risky undertaking. There are few scenarios that do not involve enclosed spaces (e.g., a car) and the potential for static discharge. Perhaps a mesh bag…
The company investigation revealed that the incident arose because insufficient water was added to the batch. This resulted in a rapid increase in temperature and evolution of hydrogen gas following the addition of aluminum powder in the last…
Do not interconnect hydrogen drain trap lines with other drain lines
Thoroughly inspect equipment installation to manufacturer’s installation instructions
Warn against unauthorized field modifications
Consult the…
