Skip to 0 minutes and 1 second The coronavirus is a problem also this week. The University of Bergen is still closed down, and we meet in my home instead of at the university campus. Because - we want to answer questions from you students! Yeah, and the first one concerns protection against chemical

Skip to 0 minutes and 20 seconds factors: What do you mean by different filters in the protective masks? I’ll show you. This is a protective mask. Il’l put it on so you can see.

Skip to 0 minutes and 43 seconds The front of the mask is the filter you ask about.

Skip to 0 minutes and 49 seconds This filter is marked white.

Skip to 0 minutes and 54 seconds That means it protects against dust particles. We have also other filters, like this one. It is marked brown. And that means it protects against organic solvents.

Skip to 1 minute and 13 seconds Yeah, that’s very important. Because you have to identify which pollutants you are exposed to before you select the filter type.

Skip to 1 minute and 22 seconds And I have a second question here: Limit values for chemical agents at work; why are they different, in different countries? Limit values - they are set to protect workers from adverse health effects. But they are not only based on health effects, also technical and economical factors are taken into consideration. This means that European limit values should not be automatically adopted by other countries, that are different with respect to working conditions and cultures.

Skip to 2 minutes and 4 seconds Then we have the last question: Can Latex gloves be used at work? Because In week 4 you have written that they may cause allergy. Yes, that is true. Latex gloves are known to cause allergies. And normally, we do not recommend to use latex gloves. However, due to the corona epidemic, the use of gloves all over the world has increased, and many countries do not have any other gloves than latex gloves left. Then you need to use them. We consider that in this situation it is more important to protect you against the corona virus than to consider the risk of allergic reactions.

Skip to 2 minutes and 51 seconds So we say: Take care!

Skip to 2 minutes and 55 seconds And health personnel: Use gloves!
