  1. TEMPORARY HEATERS PROPANE SAFETY

  2. TEMPORARY HEATERS • Circulating air type heater : • maintain 12” clearance on both sides & rear

  3. TEMPORARY HEATERS • At least 10’ from tarps, canvas or similar coverings • Set level on non-combustible surface

  4. TEMPORARY HEATERS • Locate heater at least 6’ from LPG bottle • Heater blower not directed toward bottle within 20’

  5. TEMPORARY HEATERS • LPG containers shall sit on level substantial surface • Tie cylinder in upright position if necessary

  6. TEMPORARY HEATERS • Supply fresh air • Use fans if necessary

  7. TEMPORARY HEATERS

  8. PROPANE & TEMP HEATERS • Frost on tank means • drawing too much vapor • reduced fuel flow • Don’t lay cylinder on side • Don’t change regulator setting to increase fuel flow

  9. TEMPORARY HEATERS • Carbon Monoxide • odor/colorless • 55 PPM max. exposure* • Carbon Dioxide • odor/colorless • 5,000 PPM * OSHA TLV, 1997

  10. PROPANE • For every 100,000 BTUs, use one 100 lb. tank • Separate heaters by 20’ • Max. 3 bottles (300 lb..) per heater

  11. PROPANE • Manifolds • don’t use copper, they leak! • Use only LPG or LP-Gas rated rubber hoses • No auto-type hose clamps • Test connections for leaks

  12. PROPANE • Cylinder connectors should have flame-loss device to shut-off fuel if pilot light or flame goes out

  13. PROPANE • TANKS • valve-end up while in use • place away from heaters, electrical panels, slag, flames, etc.

  14. PROPANE • Don’t take into confined spaces • Gas is heavier than air • Expands at 1:270 ratio • displaces oxygen

  15. PROPANE • Do not store inside buildings or “gangboxes”

  16. PROPANE • Protect tanks from damage

  17. PROPANE • At least one, 20-B:C fire extinguisher per storage area • 501 lbs.>, 10’ from building* * check with local FD

  18. PROPANE • 1,000 OR > pounds = • DOT placards • Bill of Lading • CDL, 21 years old, speak & read English

  19. NATURAL GAS • Flex hose* not to exceed 25’ • Leak test all connections • All connections have pull strength of 400 lb. • Flame-loss device * check with local FD
