1 What is the main difference between respirators with the "N" designation (N95, N100) and respirators with the "P" designation (P100)?

"N" is for normal use, where as "P" is for use during patient care
"P" respirators are not vulnerable to oils like "N" respirators are
"N" respirators are not vulnerable to oils like "P" respirators are
"N" respirators do not have a one-way valve, unlike "P" respirators

2 Your unit responds for a structure fire with possible trapped occupants and arrives first on scene. There is fire visible from the second story, and from the rightmost window on the first story of the building. Smoke is visible coming from all sides of the house. Your partner suggests entering the left side of the building through the open door to begin the search. You are an EMS only unit with no SCBA or bunker gear and are in a normal cotton uniform. You have N95 respirators and P100 respirators in the ambulance as well as high-visibility road gear. Should you take your partner's suggestion and enter the building in an area that is visually free of fire to begin the search for potential victims?

Yes, so long as you restrict your search to areas with no fire and wear a P100.
Yes, so long as you wear a FFR and your high visibility road gear so the firefighters can see you.
No, your respirators are not rated for potentially toxic inhalations that could result from the smoke.
No, there is an obvious scene safety hazard that cannot be accounted for.

3 A FFR with a one-way valve serves to protect the person wearing the mask, but not anyone else in the vicinity, from inhaled toxins or pathogens.


4 For your FFR to work correctly, you need to have it fit checked. This fit check should take place regularly, as well as if you have significant changes to your facial structure that could lead to a poor fit such as weight gain, trauma, surgery, or simply growing a beard.


5 You and your partners are EMTs on a volunteer fire engine and have been performing CPR for 45 minutes waiting for an ambulance to arrive at a remote location. You are all wearing N95 masks as the patient is known to have tuberculosis. One of your partners reports that "I can feel my own sweat misting out at me from my mask every time I breathe in". What should you reply?

"Don't worry, that's normal. Rest for a while and let it dry before coming back."
"It's ok, keep going. The mask will still work and filter correctly."
"You need to head outside immediately and get another mask, yours is compromised."
"You just need a break, let me switch in for CPR while you do ventilations."
