About
liquefied petroleum gases
Liquefied petroleum gases (LPG) are in widespread use in homes,
industry and agriculture. Among the many uses of these gases are for
heating and refrigeration, as a supplement for natural gas, as fuel
for industrial equipment and mobile homes, in the manufacture of ethylene,
and as a solvent. Propane, butane and propane are the most common liquefied
natural gases, and are extremely hazardous.
Highly flammable,
these gases easily ignite and burn, and will burst their containers
with explosive force. Because of the large amount of LPG in transportation,
storage and use, it is important that an active safety training programs
be set up for workers who handle these gases. It is also important
to set up an emergency response program to handle incidents involving
these hazardous materials.
About
the film
"Propane,
Butane and Propylene,"
ninth in the multi award-winning series of emergency response and
right-to-know training videos, is designed to provide industry, emergency
response, and public officials with a working knowledge of the hazards
of liquid propane gases. The film explains regulatory compliance requirements
of OSHA, DOT and EPA as well as health and safety issues relating
to LPG. The program tells where propane, butane and propylene may
be found, covers basic techniques for safe storage and handling, and
suggests procedures for emergency action in the event of uncontrolled
releases or fires.

The
film teaches how to set up a safe storage area for LPG, warning that
it is necessary to avoid exposure to high temperatures. It also tells
how to carry out a fire safety analysis at a storage site, and what
protective equipment is necessary for workers who handle LPG. Because
most releases occur during transfer operations, the film discusses how
to properly load and unload LPG to minimize the danger of an uncontrolled
leak, and how the weather affects vapors.
The phenomenon
of BLEVEs (Boiling Liquid Expanding Vapor Explosions) is explained,
and the danger of container failure is stressed. Other topics covered
include controlling vapors with water fog, monitoring for flammable
atmospheres, medical operations for victims, protective clothing for
emergency responders, ASME and DOT container types, piping systems,
and cooling tanks exposed to fire. In a fire situation, emergency
responders are taught the importance of eliminating all sources of
ignition, and that frequently the best tactic may be to allow the
fire to burn. Exciting footage of an actual incident is included.
