B737-300 CREW HAD SMOKE; FUMES IN COCKPIT AFTER LNDG AT ISP.

Narrative

AFTER LNDG AT ISP ON RWY 24; I CAME OUT OF REVERSE THRUST AND THE FO AND I NOTICED A STRANGE ODOR AND A TRACE OF SMOKE IN THE COCKPIT. WITHIN A FEW SECONDS; THE FORWARD LAVATORY SMOKE DETECTOR SOUNDED AN ALARM. WE EXITED THE RWY AT THE HIGH SPD; PERFORMED THE SMOKE/FIRE IN COCKPIT CHKLIST; CALLED TWR FOR FIRE COVERAGE; HAD THE FLT ATTENDANTS CHK LAVATORIES FOR EVIDENCE OF FIRE; AND BEGAN A SHORT TAXI TO OUR GATE. SHORTLY AFTER THE FO HAD OPENED THE OUTFLOW VALVE; THE SMOKE AND SMELL DISSIPATED RAPIDLY. I MADE A PA TO THE PAX ADVISING THEM OF THE SIT. I BASICALLY TOLD THEM THAT IF THEY HAD NOTICED A STRANGE ODOR AND A TRACE OF SMOKE NOT TO BE ALARMED BECAUSE WE HAD THE SIT WELL IN HAND. TOLD THEM TO REMAIN SEATED AND THAT WE COULD CONDUCT AN ORDERLY DEPLANING AT THE GATE. THE FLT ATTENDANTS ADVISED US THEY HAD FOUND NO EVIDENCE OF FIRE AND THEY ALSO MADE A PA TO CALM ANY FRAYED NERVES. WHEN WE REACHED THE GATE THE SMOKE AND ODOR HAD COMPLETELY DISSIPATED AND WE CONDUCTED A NORMAL DEPLANING WHICH WAS EXPEDITIOUS BUT SHOWED NO SIGN OF PANIC ON THE PART OF THE PAX. AS THE PAX DEPLANED; THE FIRE DEPT INSPECTED THE ACFT AND DETERMINED THERE WAS NO EVIDENCE OF FIRE. AFTER ALL PAX HAD DEPLANED; I CONDUCTED A DEBRIEF OF THE INCIDENT WITH THE AGENT; FLT ATTENDANTS; FO AND FIRE DEPT. ALL SEEMED TO THINK THE SIT HAD BEEN HANDLED OK. WE DID LEARN FROM THE FIRE DEPT THAT RWY 24 HAD BEEN FRESHLY SANDED PRIOR TO OUR ARR. THEY SAID THAT WHEN WE WENT INTO REVERSE SAND WENT EVERYWHERE. OUR POSTFLT REVEALED EVIDENCE THAT A LARGE AMOUNT OF SAND HAD BEEN INGESTED. BOTH BULLET NOSES HAD ALL THE BLACK PAINT REMOVED. WE DID NOT NOTE ANY BLADE DAMAGE. I CONTACTED DISPATCH AND MAINT CTL TO ADVISE THEM OF THE SIT AND WAS ADVISED BY MAINT CTL TO PUT AN OPEN WRITE-UP IN THE LOGBOOK AND THAT THEY WERE REMOVING ACFT FROM SVC PENDING INSPECTION BY MAINT. I ALSO MADE A HEADS-UP CALL TO THE BWI CHIEF PLT. SINCE WE ARE GOING TO BE USING ARPTS LIKE ISP; BUF; ALB; ETC; WHICH MAY USE SIGNIFICANT AMOUNTS OF SAND; ARE THERE PROCS WE CAN DEVELOP TO PRECLUDE SMOKE FROM ENTERING THE COCKPIT/CABIN DUE TO INGESTION OF THE SAND?
