Re: Citv Job No, l:l70627 (KRC ROLLS, 2885 OL YMPI(:),
Project No: 96-331
Per our conversation of this afternoon, the Fire Marshall will allow our request for
sprinkler omission at the sandblast room for this project, per OSSC Section 904,4.1,
subject to the following provisions:
. A technical report (as defined under Uniform Fire Code Section 103,1,1) from a
testing agency, certifying that the byproducts for the sandblasting operations are
non-combustible,
. An increased sprinkler density (as approved by the Fire Marshal), suitable for the
excess fire load which may result from a fire in the blast room, which may be
caused by the improper storage or use of combustible materials,
. Sign at the door to the blast room stating "THIS ROOM RESTRICTED TO NON-
COMBUSTIBLE CONTENTS ONLY" in 6" high 1/2" stroke letters.
If you have any questions, please call.

placed, stored or handled in the blast r09m. Any.violation

Re: Citv Job No, 970627 {KRC ROllS, 2885 Ol YMPIC\
Project No: 96-331
Per our conversation of this afternoon, the Fire Marshall takes exception to our
request for sprinkler omission at the sandblast room for this project, per OSSC
Section 904.4.1, The reasons given were:
. There are combustible materials and finishes within this room, in the form of
plywood wall surfacing and rubber sheeting,
. There may be residual rubber from the rolls which may be introduced into the air
during blasting operations,
Based on the above we request clarification of the following:
. If the owner could demonstrate that there was no significant amount of
combustible material removed from the rolls during blasting and if the plywood
and rubber sheeting were replaced with a non-combustible surfacing (such as
cement board), would the Fire Marshall permit the sprinkler omission?
If you have any questions, please call.

Re: Citv Job No, 970627 {KRC ROllS, 2885 Ol YMPIC\
Project No: 96-331
The owner is requesting sprinkler omission at the sandblast room (720 sq. ft. area)
for this project, per OSSC Section 904.4.1, The reasons given are as follows:
. The highly abrasive sandblasting process in this room will lead to failures in the
sprinkler heads, and accidental discharge of the fire sprinkler system,
. If water is introduced into the blasting and sand-reprocessing equipment, the
room and all of its related equipment will have to be entirely cleaned and the
process will be shut down for approximately one week, at a large cost.
. The room is constructed of masonry walls and pre-cast concrete decking, with
steel doors, making the entire structure non-combustible (the walls of the room
are sheathed with %" plywood with 3/32" rubber sheeting attached over the
plywood to dampen the rebound of sandblast particles and avoid erosion of the
masonry),
. The room is used for sandblasting non-combustible metals from large steel rolls.
The sand is transported from this room to a filtering system and reprocessed,
Based on the above we request permiSSion to omit the fire sprinklers from the
sandblast room,
If you have any questions, please call.
Sincerely,
<\
