Safety Precautions
Midland valves are used in connection with a variety of products, many of which are hazardous materials
and could cause serious injury or damage.
This valve should only be installed, operated and maintained by qualified personnel.
Read all of these instructions carefully before proceeding.
CAUTION
:
Toxic Hazard.
Always use extreme caution and proper equipment when
involved with hazardous materials. To avoid exposure to toxic or hazardous
materials, make sure the tank car is empty and clean, and that the work area is free
of hazardous chemicals before removing or installing any valve.
WARNING:
These internal-style pressure relief valves are spring-loaded assemblies
with a large amount of stored potential energy in the spring. Handle with care to
avoid damage to the valve stem, which could result in breakage and ejected piece
parts.
WARNING
: When assembling or disassembling the valve, DO NOT position oneself
directly in front of the spring and stem. Instead, position oneself to the side away
from the valve. Unexpected component failure – valve stem or spring breakage -
may cause a sudden energy release discharging component parts a short distance
in an uncontrolled manner. Personal injury may be a result.
