Free-Fall Lifeboat. A free-fall lifeboat is the fastest way of escaping from a vessel/platform in emergencies. They simply slide out from a ramp onboard and hit the water well away from the ship or installation with a high positive forward motion.
For every 4 hours you work you should get a 15 minute break. You have to work 6 hours for a 30 minute break and I think its 8 hours for an hour break. In a day of 8 hours duty, the lunch break will be after 4 hours and a tea has to be served or will be taken within the campus in 2 hours before that.
Employers like fast food restaurants commonly hire high school students. Technically if you worked 7 days a week, 4 hours on weekdays and 8 hours on weekends you could work up to 36 hours per week but I would not recommend working that many. Chose a reasonable amount to start, maybe 12-15.
