What Safety Precautions Should I Take Before Using Chemicals?

It is always wise to work as safely as possible when working with chemicals. Even substances that do not seem dangerous at first can cause enormous damage if they get into your eyes. Therefore, always wear safety goggles. You also want to prevent chemicals from ending up on your skin, which is why it is important to always use good gloves or disposable gloves.

Respiratory protection is necessary for volatile substances, vaporous liquids and solids that dust. There are many different types of filters, so you should always refer to the MSDS to find out which filter you need. Many filters also specify which substances they are for.
