I've been working in a facility that handles, melts, processes and ships sulfur. For those of you that don't know anything about the stuff, it's interesting to say the least.
Sulfur starts melting at approximately 240 degrees Fahrenheit. At 275 degrees, it flows like water. At 300 degrees, it becomes thicker and is like heavy syrup at 325 degrees.
In molten form, sulfur release Hydrogen Sulfide, which is a deadly gas. To warn us of accumulations, we wear monitors that beep, when the concentration reaches a certain level. When they beep, the best thing is to walk across the wind and move away from the area. This hasn't happened often, but it has happened.
Sulfur, when mixed with water, will create a weak solution of sulfuric acid. Steel not coated starts corroding immediately, when exposed, and can become severely corroded in a short period of time. Even stainless steel is not immune from the acid. Eventually, it too is eaten away.
Sulfur has a distinct, and strong odor. If you've never smelled it, buy some matches and smell an unlit match. When working around the stuff, the odor is substantially stronger and clothes will reek of this odor at the end of the day. It takes a few washings for the odor to disappear.
When melted, sulfur is a clear, red liquid; much unlike the bright yellow, when solid. When it burns, it becomes a darker yellow and releases Sulfur Dioxide, which is another deadly gas. Having a fire is common and can be started by as little as an automobile tire causing friction as it rolls over sulfur.
So, now you're wondering what I'm doing. I'm in charge of replacing some concrete that is almost destroyed after years of exposure and replacing the sheeting on a large building. I anticipate a few months before we're finished and will work out of town until complete.
I've become used to the environment, but sometimes the sulfur makes me sneeze and always gives my sinuses a fit. I'm rewarded with slight laryngitis when I return home every week, due to sinus drainage. By Monday, it's gone, but I know I'll have it again by the end of the next week.
