Pnuematic Circuit Breakers or Velocity Fuses
The Occupational Safety and Health Act (0. S. H.A.), Section 1926.303, Para-
graph 7, published in the Code of Federal Regulations 29 CFR 1920.1, revised
July 1, 1982 states that all hoses exceeding l/2° inside diameter shall have a
safety device at the source of supply or branch line to reduce pressure in case
of a hose failure"
These pnuematic safety devices are designed to prevent hoses from whip-
ping and/or the loss of hazardous or toxic gasses, all of which could result in a
serious or fatal accident.
Never join pipes or fittings with lead-tin soldering. Welded or
W~NING ! threaded steel pipes and cast iron fittings, designed forthepres-
sures and temperatures, are recommended.
Pressure Vessels
Air receiver tanks and other pressure containing vessels such as (but not
limited to) pulsation bottles, heat exchangers, moisture separators and traps,
shall be in accordance with ASME Boiler and Pressure Vessel Code Section
VIII and ANSI B 19.3 safety standards. They should be equipped with a
pressure reliefvalve, pressure gauge, tank drain, & manual shutoffvalve (refer
to Fig. 3-1, Typical Drop Leg& Component Location).
ASME coded pressure vessels must not be modified, welded, re-
WMNING !
paired, reworked or subjected to operating conditions outside the
nameplate ratings. Such actions will negate code status, affect
insurance status and may cause property damage, severe injury or
even death.
A drain valve should be located in the bottom of the air receiver to allow for
moisture drainage. Extend piping away from the unit to provide safe and
convenient removal of excess moisture. An automatic drain valve is recom-
mended.
If the air receiver is going to be subject to temperatures of 32°F or below,
provisions must be made to guard against freezing of the pressure reliefvalves,
pressure gauge, and moisture drain.
