Handling and Disposal
*
Spill Release Procedures: REMOVE POSS IGNIT SOURCES & IF NEEDED, USE
  NONSPKG TOOLS & EQUIP. DETERM WHETHER TO EVACUATE OR ISOLATE AREA
  DEPENDING ON SUCH SPECIFIC FACTORS AS SITE LOCATION, POPULATION DENSITY,
  TRAFFIC FLOW, SIZE  OF RELS OR SPILL, WEATHER CNDTNS, MATL'S HAZS & RISKS
  TO PEOPLE & WHETHER FIRE IS UNDERWAY OR POSS. MOP UP, WIPE UP OR SOAK UP
  W/ABSORB & PLACE IN VENTED CNTNR FOR SALVAGE OR (SUPDAT)
Waste Disposal Methods: DISPOSAL OF COLLECTED PROD, RESIDUES & CLEANUP
  MATLS MAY BE GOVERNMENTALLY REGULATED. OBSERVE ALL APPLIC LOC, STATE &
  FED WASTE MANAGEMENT REGS. WHEN DECISION IS MADE TO DISCARD MATL, AS
  RECEIVED, ISIT CLASSIFIED AS HAZ WASTE?: YES. FED HAZ WASTE CODE: NA.
  (TOXICOLOGICAL INFO)
Handling And Storage Precautions: HNDLG: NO SPEC PRECS. STORAGE: KEEP CNTNR
  CLSD & AWAY FROM HEAT, SPKS & OPEN FLAME. PROD EVOLVES MINUTE QTYS OF
  FLAM HYDROGEN GAS. DO NO REPACKAGE OR STORE IN UNVENTED CNTNRS. ADEQUATELY
  VENT WORK ARE A TO MAINTAIN VAPS WELL BELOW ESTABLISHED FLAM LIMS & EXPOS
  GUIDELINES. KEEP (TOXICOGOCIAL INFO)
Other Precautions: AVOID EYE CNTCT. USE REASONABLE CARE. COMMENTS: USE AT HIGH
  TEMPS MAY EVOLVE OR GENERATE PHENYLHEPTAMETHYLCYCLOTETRASILOXANE &
  2,6-CIS-DIPHENYLHEXAMETHYL - CYCLOTETRASILOXANE. PROVIDE ADEQ VENT TO CTL 
  W/IN EXPOS GUIDELINES. PERS SHOULD WEAR NIOSH APPRVD ORG VAP RESPS UNTIL
