OSHA
29 CFR 1910.151 states the following:
When the eyes or body of any person may be
exposed to injurious corrosive, toxic, or
flammable materials, suitable facilities for quick
drenching or flushing of the eyes and body shall
be provided within the work area for immediate
emergency use.
ANSI Z358.1-1998
Standard states the following:
Delivered flushing fluid temperature
shall be tepid. This standard also establishes minimum performance
and use requirements for eyewash and shower equipment for the
emergency treatment of the eyes or body of a
person who has been exposed to injurious
materials.
-
The shower must have a minimum of
20 GPM for 15 minutes of controlled flow
[ANSI 4.5.2 (4)]
- The eyewash
must have a minimum of 0.4 GPM for 15 minutes of controlled flow
[ANSI 5.3.2 (3)]
- The eye/face
wash must have a minimum of
3.0 GPM for 15 minutes of controlled flow
[ANSI 7.1.4]
- Units must
meet all individual performance requirements when all components are
operated simultaneously.
HOW DOES THE HUBBELL UNIT
ACHIEVE THESE REQUIREMENTS?
|
The
Hubbell EMV water heater system provides
high volume tepid water for safety drench systems by integrating
a specially
designed mixing valve with a high quality
cement lined electric storage water heater.
The model EMV is designed to maintain 120
gallons of water at 170°F. The volume of
water at this temperature is necessary to
achieve the final flow rate of 23 GPM for 15
minutes of tepid water. When an emergency
drench apparatus is used, the integrated
mixing valve blends 170°F water from the
tank with incoming cold water to achieve a
continuous flow of approximately 85°F tepid
water to operate simultaneously a safety
shower and an eye/face wash fixture.
|
Note: For 30 GPM shower heads the Hubbel EMV will provide 75 F water for
15 minutes. |

The
Hubbell EMV water heater satisfies the tepid water requirements for
a safety drench system.
The
Hubbell EMV water heater package is specifically
designed to meet your emergency drench
system needs by incorporating the following
critical features:
- The
carbon steel tank is internally lined with specially formulated hydrastone
cement and
does not require anodic protection. This
lining is critical to the longevity of the tank
when storing hot water at elevated
temperatures.
- The mixing
valve is specifically designed for emergency safety drench systems
and is
factory piped and packaged with the water
heater tank to simplify installation and
ensure a safe and dependable system.
- The
Hubbell EMV Model has 3" foam
insulation which reduces stand-by heat losses
by over 24% compared to 2" insulated tanks.
This provides the owner with a highly efficient
and economical solution for emergency drench
systems.
- Unlike
instantaneous heaters, the Hubbell model EMV is unaffected by the
loss of
electric power in its ability to provide tepid
water. Furthermore, the dial temperature gauge
provides the operator with positive visual
verification that the unit is at temperature.
