How much air is in a SCBA bottle?
The cylinders contain about 1240 litres of compressed air at 200-atmosphere pressure. This gives the wearer around 31 minutes of air supply for full usage or about 21 minutes for working conditions (person breathes heavily during work hence there is more consumption of air and that is why the time is lesser)

How often should you inspect a Scott respirator?
SCOTT recommends that this respirator be inspected and tested by a SCOTT Authorized Service Center using SCOTT Authorized Test Equip-ment at least once a year. Heavy use and/or severe service conditions may require more frequent inspection and testing. This recommendation is in addition to all other cleaning and maintenance procedures. in addition, all air cylinders used with SCOTT respirators must be periodi-cally visually inspected and hydrostatically tested by a licensed cylinder retester. The cylinder inspection and test must be done in accordance with the appropriate uS department of Transportation (dOT) specifi-cation or the applicable dOT exemption. See step 2 of the REguLAR OPERATiONAL iNSPECTiON section of this instruction.
How to contact Scott?

Testing/burst hazards (Data for 4500 cylinders, 5500 cylinders also exist)
The burst pressure for the tri-dimensional burst disk used in the Scott is 4800 psi. Carbon composite cylinders are made up of an aluminum alloy inner shell with carbon composite wraps and epoxy resin. They have a burst pressure of 12,000 psi, 6,500 without the carbon composite wrap.
Valve assembly
The valve assembly is the appliance which will make the connection between the cylinder and the hose (which will send the air to a pressure reducer). It is constructed of forged aluminum alloy, and is angled to reduce stress of the connection made between the high-pressure female coupling of the high pressure hose. Newer cylinders contain a "tri lobe, ergonomically designed hand wheel." This hand wheel is a one-way, ratcheting type knob which is a push to close style k…
Effect of temperature on pressure gauge readings
The pressure gauge's indicated gas pressure changes with ambient temperature. As temperature decreases, the pressure inside the cylinder decreases. The relationship between the temperature and the pressure of a gas is determined by using the formula PV = nRT. What is particularly important to understand from the formula is that the temperature is in kelvins, not degrees Fahrenheit. Consider the freezing point of water at 32 degrees Fahrenheit (0 degrees Celsius) an…
