Is it really necessary to wear protective gear when I'm bleaching clothes, spraying aerosol/insecticide etc?

Question

How much of a difference does a protective mask make?

Answer 1

It depends on the chemicals you're using. You should look at the ingredients of those products (particularly the effective ingredients), and then search for the MSDS sheet for those chemicals on Google or Yahoo! The MSDS sheet will tell you what the harmful effects are (if any) when you inhale, ingest, or come into contact with, or get the chemicals in your eyes. Generally, yes, it's a good idea to wear protective gear. Why would you risk it or be stubborn about something that's for your safety and not all that hard to do?
