Answer:

how can we determine the capacity of extinguisher(L of Kg)?
They are different capacity extinguishers. All are for 'A' class simple fires. hanford /fire/safety/extin
The kids and I have done many cross country trips! They are great! One year I had the camper - we would just stop at the rest stops for the night. Make sure you have plenty of games! Give each one of those pencil boxes that close - the plastic ones with age appropriate toys - crayons etc. I kept a cooler in the passenger seat so I could take care of needs. Also, I got it down to where I would stop at each half tank or close. So then they knew when we were stopping - they could look at the gas gauge themselves. DVD's - Video games - whatever! CD's of kids songs that you can all sing together. My kids love those times, except driving through Texas and Pennsylvania. I swear my 16 year old gets a twitch when we mention Texas in regards to driving. It takes sooooo long to get to the other side! But it is beautiful though! We woke up one day and got out of the camper and just stood there in awe! Enjoy!
Most public buildings such as work places/schools etc have the same guidelines for when a fire/evacuation alarm sounds - standard procedure would be to vacate the premises, go to the designated assembly point to be registered as being out of the building, and await further instructions from your superiors. It doesn't matter whether you are on a break or not - if the fire alarm goes off, stick to the building's guidelines (which they should have) and get out of there. If you are on a break outside of the premises and hear the alarm, go to a designated assembly point (which again, the building should have), or let yourself be known to a member of staff so they don't think you are still in the building. Most importantly, don't go back for belongings or try to be a hero.
Like when they say 4A:60B:C? Well, it's the letters that correspond to the types of fires the extinguisher is rated for. A - Wood, Paper, Trash B- Flammable Liquids and Gases C- Electrical Fires and so on The numbers are ONLY associated with the letters A and B. The numerical rating of an extinguisher provides a guide to its extinguishing ability as result of fire testing by Underwriters' Laboratories, Inc. The numeral indicates the approximate relative fire extinguishing capacity of the extinguisher for that class (A or B) of fire. Generally the larger the extinguisher, the larger the numbers. (It's mostly about the capacity of the unit.) For some examples, a 4-A extinguisher can put out approximately twice as much fire as a 2-A extinguisher, and a 20-B:C extinguisher can put out approximately twice as much flammable liquid fire as a 10-B:C extinguisher. For Class B extinguishers, the numeric rating also indicates the fire suppression capacity of the extinguisher when used by an inexperienced operator. That is, a novice can put out a fire encompassing 10 sq. ft. (.9 m2) with a 10-B:C extinguisher and a 20 sq. ft. (1.8 m2) fire with a 20-B:C extinguisher. The fire suppression capacity is related to the experience of the operator. For example, an experienced operator can put out a fire encompassing 25 sq. ft. (2.3 m2) with a 10-B:C extinguisher and 50 sq. ft. (4.6 m2) with a 20-B:C extinguisher. Class C extinguishers carry only the symbol and have no numerical rating because such fires are essentially Class A or Class B fires involving energized electrical equipment. That's about it.
