There is a serious problem related to global warming is that in British Columbia there is a scourge of our pine trees occurring in our dry Interior of what is called a pine beetle. Since it doesn't get below about -30 degrees centigrade for 3 weeks anymore in the winter, these pests do not get killed in the winter so for probably at least 15-20 years now they have gone on the rampage and killed large swaths of our pine forests.
When the sawmills in BC saw this pine beetle-killed lumber it is so dry it creates a lot of fine dust in the mills. Due to poor control of this dust there has been two explosions in which this dust has ignited and 2 or 3 workers have been killed as a result. So in this way global warming can be deadly to human activity if extra precautions are not taken.

a. tie it back before performing lab work.
Using a Bunsen burner can cause your hair to loosen and ignite. Bring only your essentials to the lab. This means that all personal belongings such as bags and jackets should be kept outside. Long hair and loose clothing that can get caught in glassware or pose a danger in the laboratory should be withdrawn.
Wear proper clothing when working in the laboratory. Long hair, hanging jewels, loose clothing, and baggy clothing are dangerous in the laboratory. Long hair should be tied at the back. You need to secure the removed jewelery (if it's hanging long) and loose clothing. Shoes should completely cover your feet.
