Chemical Safety

People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car.

This brings to mind the reason why chemical safety is so important and why you should always use the chemicals that you own for their intended purpose only. Otherwise, the repercussions could be disastrous to say the least. There are specific things that you and those around you should do when handling, storing or using chemicals in nearly every form.
