0.26 inches
E cylinder of oxygen capacity is
660 liters
E cylinder capacity of nitorous oxide is
1590 lites
Fusible plug?
offers protection from excessive pressure from high temperature but not from overfilling
rupture disc
protects against excess pressure from high temperature or overfilling
Cylinders must be inspected how often
every 5 years
safety systems what are they
help avoid incorrect gas connections and include color coding, pin indexing and diameter indexing
oxygen should be changed at
1000psi
full cylinder pressure for O2
2200 psi
full cylinder pressure for air is
2200psi
full cylinder pressure for nitrous is
745-750
pipelines are used to deliver nonflammable gases such as
oxygen, nitrous oxide, air, carbon dixoide, and nitrogen
how can central supply oxygen be stored
as cryogenic liquid a low pressure, or as compressed gas in cylinders
what is the most common contaminant of medical gas lines
wate
who determines the purity of meidcal gases
specified in the US pharmacopeia and enforced by the food and drug administration
who have published standards reguarding cylinders
DOT, National fire protection association, and compressed gas association
What is the mos common cause of leak in new cylinder
missing or defective washer
What kind of safety is used in pipeline connections
DISS from the pipeline to the anesthesia machine is used
What is a cylinder gas regulated to before entering the anesthetic machine
50psi
what are some hazards in pipeline systems
leaks, fires and cross-connections
what do pipeline alarms tells us
indicate if the pressure increases or decreases 20% from normal
