OPERATING PROCEDURES
HIGH PRESSURE BREATHING AIR (Primary Supply) (cont’d)
8.2
1.
When planning your dive you must take into consideration the amount of time a given
bottle will last, and the number of bottle changes, which will be necessary during the dive.
There are two options that can be used to accommodate dives that will have a high
consumption of air.
2.
Use twin tanks instead of singles. Use a high volume cylinder (250 - 300 cubic feet) of
breathing air; these can generally be rented from a welding gas supplier, or supplier of
industrial gases. Make sure you specify breathing air, and request certification. These
cylinders can be also be manifolded quite easily. Generally the charge for rental is very
competitive in cost and usually includes delivery to the job site.
Note:
When using high-pressure cylinders, care must be exercised in the handling, transport and
storage of it. Make sure all personnel involved are instructed in the proper procedures. If you have
any questions regarding the proper procedures contact your supplier.
