Closed valve with open bleeder

LEVEL 2—CLOSED VALVE WITH OPEN BLEEDER [Pg.65]

The open bleed/vent valve represents a low-pressure spot in the system. Therefore, if there is a release through the closed block valve, the hazardous materials will bleed off before entering the equipment being worked on. If the discharge from the bleed/vent line could itself be hazardous, it can be routed to a safe location, such as a flare header. [Pg.65]

If the hazardous chemical is a liquid, the bleed valve should point downward if it is a vapor, then the bleed valve should point up. [Pg.65]
