CEA 4001 - Plastic Packaging Recycling Plants

165
The sprinklers shall have the following characteristics:
- spray sprinklers
- K-factor min. 57
- RTI-value quick
- upright
Furthermore, baffles or water shields for the sprinklers shall be installed to avoid cooling (see 11.3) and
to protect them against dripping plastics.
The hydraulic design of rack protection shall consider the following parameters:
- area of operation of 90 m² for each level in addition to the ceiling protection (see figure)
- 0.5 bar minimum pressure at sprinkler
K.9.2 Ceiling protection
The ceiling protection shall have the following characteristics:
- design: 10 mm/min over 260 m²
- K-factor min. 80
- RTI-value special or quick
- protection area per sprinkler max. 9 m²
K.9.3 Additional measures
Foam proportioning with AFFF foam for rack and ceiling protection shall be provided.
For limiting horizontal fire spread vertical non combustible sheet barriers shall be installed within one
double rack line and at a maximum distance of every 7 m.

K.10 Plastic Packaging Recycling Plants
K.10.1 General
This concept is based on fire tests and shows one possible solution to provide an adequate protection.
The different areas of plastic packaging recycling plants shall be protected by sprinkler or deluge
systems according to the amount of combustible loading available. Pneumatic conveyor equipment may
require additional protection by spark extinguishing systems. As the fire extinguishing of bulk and
bale storage requires additional clearing and follow-up extinguishing measures, it is necessary to
have direct alarm transmission to a permanently manned station.
The protection concept should be agreed with the authorities during the planning stage.
K.10.2 Design data of sprinkler systems for recycling plants
A sprinkler system shall be used for:
ƒ free pile storage
ƒ bale storage (compressed plastic)
ƒ sorting area
The following equipment should be protected by an additional water extinguishing system (sprinkler
