WARNING: TO AVOID POTENTIAL SEVERE BURNS, SERIOUS INJURY
OR DEATH, PERSONNEL MUST READ SECTION 2 (SAFETY
PRECAUTIONS) BEFORE OPERATING BEARCAT
EQUIPMENT
WARNING: EXTREME CARE MUST BE USED WHEN CHANGING AN
ASPHALT DISTRIBUTOR FROM WET ASPHALT TO HOT
ASPHALT. FAILURE TO FOLLOW THE PROCEDURES
COULD CREATE A POTENTIAL STEAM EXPLOSION
HAZARD, RESULTING IN SEVERE BURNS, INJURY OR
DEATH.
WARNING: IF ANY MOISTURE IS PRESENT IN THE TANK OR IF THE
DISTRIBUTOR WAS PREVIOUSLY USED WITH
EMULSIFIED OR WATER BASED MATERIAL, DO NOT
LOAD WITH NEW MATERIAL AT ANY TEMPERATURE
ABOVE 200°F (93°C). BEFORE MACHINE CAN BE
LOADED WITH HOT MATERIAL, IT MUST BE FLUSHED
USING THE TANK FLUSHING PROCEDURE.
Anytime an asphalt distributor has been used with “emulsified asphalt” or
a “water based” product it should be considered “wet”. When changing
to hot asphalt (any material over 200°F (94°C) extreme caution must be
taken. Emulsified asphalt is approximately 40% water. Water boils at
212°F (100°C) and converts to steam. The water is heavier than asphalt, so
it is at the bottom when it converts to steam. This process can take only
seconds. When the water converts to steam, it displaces the asphalt with
enormous force. This will cause the tank to boil over or even erupt
splashing hot asphalt on everything within a 100 foot radius.
NOTE: Hot is any material that is in excess of 200°F (94°C).
