PROPANE & TEMP HEATERS

Frost on tank means
– drawing too much vapor
– reduced fuel flow


Created by GE Johnson Construction Co.
Don’t lay cylinder on side
Don’t change regulator
setting to increase fuel flow
TEMPORARY HEATERS

Carbon Monoxide
– odor/colorless
– 55 PPM max.
exposure*

Carbon Dioxide
– odor/colorless
– 5,000 PPM
* OSHA TLV, 1997
Created by GE Johnson Construction Co.
PROPANE



For every 100,000
BTUs, use one 100
lb. tank
Separate heaters by
20’
Max. 3 bottles (300
lb..) per heater
Created by GE Johnson Construction Co.
PROPANE

Manifolds
– don’t use copper,
they leak!
– Use only LPG or LPGas rated rubber
hoses
– No auto-type hose
clamps
– Test connections for
leaks
Created by GE Johnson Construction Co.
PROPANE

Cylinder connectors
should have flameloss device to shutoff fuel if pilot light or
flame goes out
Created by GE Johnson Construction Co.
PROPANE

TANKS
– valve-end up while in
use
– place away from
heaters, electrical
panels, slag, flames,
etc.
Created by GE Johnson Construction Co.
PROPANE



Don’t take into
confined spaces
Gas is heavier than
air
Expands at 1:270
ratio
– displaces oxygen

Do not store inside
buildings or
“gangboxes”
Created by GE Johnson Construction Co.
