Compressed gas emergency

A GC column containing 2.30 mL of void space occupied by gas and 0.125 mL of liquid stationary phase is operated at a compression ratio of 4.00. For a component having a distribution coefficient K = 105, calculate the volume of gas emerging from the outlet prior to the appearance of the peak center for that component. Calculate also the volume of gas entering the inlet prior to the emergence of the peak center. 

Seatbelt assemblies or seatbelt modules include the straps, webbing, buckles, adjusting mechanisms, fasteners, and related hardware designed to secure people in a vehicle to minimize risk of harm in a collision. Most modules are mechanical, but some contain a pyrotechnic or compressed gas seatbelt pretensioner which, in an emergency, forces the retractor to take up any slack in the seatbelt. 

Employers are responsible for the safe use of compressed gas cylinders and liquid containers and their contents. Compressed gas hazards include oxygen displacement, explosion, and toxic effects. There is also the hazard of a ruptured cylinder. Employers must evaluate the compressed gas-hazards and have an emergency response plan that defines procedures and responsibilities to address emergencies.

Hospitals, rehab-clinics, emergency services and registered doctors with own practices receive medical oxygen either in large quantities in liquid state by tank trucks or in compressed gas cylinders (single cylinders or cylinder bundles), if smaller quantities are required. 

Labeling requirements are more strict with international shipments of compressed gas mixtures from the United States, as many of them move by sea or air. Since the vessels used in both of these modes of transportation are difficult to evacuate quickly in the event of an emergency, many gases and gas mixtures may have to be classified as poisons that would not be classified as such for domestic land transportation.
