CABIN HARNESS / SEAT BELTS
There are additional cabin safety equipment that are installed for the safety of both passengers and crew members. Cabin harness is one of these safety device installed on the seats as commonly called as Seat belt.
Most common term used for the cockpit crew seats and cabin crew seats are safety harness. This harness provides positive locking on the seat whoever wears the same in case of sudden stop or impact like in Rejected Takeoff.
Operation of the Seatbelt
(1) The buckles are inserted to each other
(2) These are pulled to tighten up comfortably depending on the waist line
(3) Lift buckle to disengage

AIRCRAFT EMERGENCY ESCAPE SLIDES
In case of cabin emergency, the aircraft is provided with emergency escape slides on each passenger door. Escape slides are used to help people evacuate the aircraft as quick as possible. The installation of this emergency escape slide assembly are normally on the lower part of the passenger door.
If the arming lever on the door is selected to ARM position and the door on that side is Open, then, the emergency slide will be deployed and then Inflation will follow to that side of the door automatically. In case of failure of inflation after deployment, then a manual inflation handle on the right side of the door normally in Red color must be pulled to activate manual inflation. Escape slides are being inflated automatically once the door is opened and the control handle is set to armed mode, which usually takes 4 seconds to be completely inflated.
THERAPEUTIC OXYGEN
The therapeutic oxygen is also provided as part of the first aid and safety device inside the cabin for emergency purposes. There are times or incident that a pass...

...tations. The chemical oxygen generator is sufficient to supply oxygen at least for 15 minutes just in time that the aircraft can make a rapid descent.
The chemical oxygen generator is ignited by one of the lanyard pulled by any passenger when the oxygen masks are deployed. This will release the pin which will trigger the firing pin and the inside chemicals of iron plus sodium chlorate burn to produce the oxygen product.
It will be available at the outlet manifold of the chemical generator itself which are individually connected to each passenger masks. It will be a continuous flow of oxygen once it is generated so that the passenger must individually consume it by putting on the mask on their face as soon as possible if it happens during flight. The 15 minutes period will start after the oxygen is generated and ready for use.

There are many internal parts to the injector. Starts with a barrel then moves down to a plunger then there is a check valve, below that is a spacer with the nozzle springs inside of it, lastly is the nozzle. All of these parts have specific and unique jobs. Nozzle has a needle in it that works kind of like a piston that once the pressure build up the needle forces forward and sprays fuel. There is a spacer above the nozzle with the nozzle springs that force the needle down. Above the spacer is a check valve, the check valve allows the right amount of fuel into the nozzle. The plunger and barrel are located above the check valve. It has a spring on the plunger that has to hold resistance of the pressure until it reaches the correct amount before it will let the injector fires. There is two internal o-rings one that is around the plunger and one that sets between the nut and body.
In addition, the pressure needed to activate the set of panic hardware does not fit the emergency situation and the user too. It should be easier and faster in activation as it is designed for emergency escape plan.

The practice of seat belt is a tactic for security while having a weapon on hands like it is a car. Seat belts are life keepers at certain circumstances. Their design role is to lock in an unexpected or abnormal movement generated in the engineering

The seat belt or safety belt is a safety harness designed to secure the occupant of a vehicle against harmful movement that may result from a collision or a sudden stop. As part of an overall automobile passive safety system, seat belts are intended to reduce injuries by stopping the wearer from hitting the hard interior of the vehicle, or other passengers, when in the correct position for the airbag to deploy it prevents the driver and passengers from being thrown from the vehicle. Seat belts absorb the energy of the impact by being designed to stretch during any sudden deceleration, so that there is less speed differential between the passenger's body and their vehicle interior, and also to spread the loading of impact on the passenger’s
Current seat belt law originated from federal legislation in the 1960s that made it mandatory for all automobile manufacturers to include seat belts in their vehicles as a standard feature. Originally, the purpose of a seat belt was not to protect the occupants in the case of a crash, but rather to physically keep them in the vehicle, as driving was bumpy business.
Many people may choose not to wear a seatbelt because they don’t understand how and why they work. To begin with seatbelts are the first line of defense one has against an injury in a crash.
Does everyone have their seat belts on? This is a question that children hear repeated each time their parents start the vehicle. Seat belt laws are enforced in in forty-nine of the fifty states even so; parents reiterate it time after time to keep us safe rather than just following the law. Beginning in the 1930’s, physicians determined that a lap belt should be used in automobiles to avoid serious injury or a fatality. Over the years, the simple two-point lap belt has evolved into a multiple point seat belt used for many different types of driving. Racer car drivers generally use a five-point harness. However, for normal every day driving “the three-point”, lap and shoulder combination “is considered the safest version and is the kind found in most vehicles today” (“Seat Belts”, 2010). Seat belts are the primary prevention of ejected passengers. Opponents argue that wearing seatbelts should be a personal choice, not something enforced by a law. Proponents support the initial theory; it is safer to remain within the confines of the vehicle for increased protection. It is imperative that seat belts laws are enforced to increase seat belt use, decrease motor vehicle injuries and fatalities, in addition, reduce costs in medical expenses and insurance claims from automobile accidents.
They have straps, lap bars, set belts, and shoulder harnesses to make sure you and everyone else is safe and can enjoy the ride.

Seat belt usage is a struggling problem today through out the United States. It is also lower then any other industrialized nation in the world. The best way to prevent a death in a motor vehicle accident is to wear a seat belt. Everybody has their opinions on safety belts and the laws that go with them, but until they prove them harmful, people recommend for occupants to wear it while in a vehicle. Still today people want it to be a national law for people to buckle up. Estimations from people all over the country prove that seat belts really help save lives. But also some safety belts have failed and have cause people to get trapped in the car. For instance, if someone happens to run off a bridge and go into the water, they would have to
Seatbelt is a very important component when we all drive a car or other vehicle. The main purpose of seat belts is to provide greater safety to the driver when driving car but at the moment, people do not care about the importance of wearing seatbelt.
Seat belts help prevent injury when driving. Most car accidents happen when someone is drunk , texting on their phones, or driving too fast. An average of 35,000 people die every year in car accidents. Most of them died because they weren't wearing their seat belts. Some injuries that happen when you don't wear your seat belt are damage to the head, shoulder, stomach, chest, ribs, neck, and hips. The seat belt shoulder straps keep your head from hitting the windshield, dashboard, steering wheel and other hard surfaces. Seat belts reduce serious crash- related injuries and deaths by 50%.
