- Refineries & Petrochemical plants go to great extremes prior to
routine maintenance or unit shutdowns to isolate sewer openings from the
atmosphere.
|
|
8
|
|
|
9
|
- Why do Refineries and Petrochemical plants go to extremes to isolate
sewer openings during routine maintenance and turnarounds? To prevent an ignition source from
igniting combustible sewer gases and causing sewer explosions.
|
|
10
|
|
|
11
|
- The most common method used to cover sewer openings is a vinyl container
filled with water. Some still use
fire blankets covered with sand.
|
|
12
|
|
|
13
|
- Neither method provides a positive seal because the surface normally
concrete, is never perfectly smooth or without cracks and chips.
|
|
14
|
|
|
15
|
- One major problem associated with any method that seals the drain is
that flooding can occur and create a major safety problem.

|
- WHAT MAJOR SAFETY PROBLEM IS ALWAYS PRESENT WHEN FLOOING OCCURS DURING A
UNIT SHUTDOWN?
|
|
18
|
|
|
19
|
- Movement of equipment such as cranes & forklifts during a unit
shutdown without damaging conventional type seals over a catch basin is virtually
impossible.
|
|

|
|
|
21
|
- Envirosafe Sewer Seals for surface drain catch basins and pump drain
hubs provide a solution to the problems associated with using sand or
vinyl water containers to seal catch basins and pump drain hubs prior to
hot work
|
|
22
|
- The water seal in the patented Envirosafe Sewer Seals provide a positive
seal that prevents any combustible sewer gases from being ignited
causing a sewer explosion.
|
|
23
|
|
|
24
|
- The difficulty of moving equipment during a unit shutdown is eliminated
because the Envirosafe Sewer Seal fits inside the existing catch basin –
not above it!
|
|
25
|
|
|
26
|
- The flooding problem is eliminated because the Envirosafe Sewer Seals
provide continuous water flow.
