Leak Checks: Why, When, and Types
High Pressure Using a High Pressure Gauge
Leak checks determine if the propane piping system is suitable for service and
must be performed on the vapor distribution piping system immediately after
turning on
the gas in a new gas system or a system that
has been restored after an interruption of service.
If leakage is indicated, shut off the gas until the necessary repairs have been
made.
As opposed to a pressure test, a leak check includes the piping system connected
to the appliance(s).
The type of testing instrument used in performing a leak check depends on the
type of leak check being performed.
For a high pressure leak check, the testing instrument is placed after
the first stage regulator and before the second stage regulator. This test
usually uses a 30 psi gauge.

Leak Checks: Why, When, and Types
Low Pressure: Using a Magnehelic Gauge
Leak checks determine if the propane
piping system is suitable for service and must be performed on the vapor
distribution piping system immediately after turning on the gas in a new gas
system or a system that has been restored after an interruption of service.
If leakage is indicated, shut off the gas until the necessary repairs have been
made.
As opposed to a pressure test, a leak check includes the piping system connected
to the appliance(s).
The type of testing instrument used in performing a leak check depends on the
type of leak check being performed.
For a low pressure leak check, the testing instrument is placed into
the low pressure system (1/2) lb pressure or less) at or after the integral 2
stage regulator or at or after the second stage regulator. The test instrument
is subject to low pressure because the regulators have already dropped the
pressure in the system.
Low pressure leak tests may be accomplished using a water manometer or
magnehelic gauge.

Roadside Stop: Part 1: DOT Licensing and Driver Requirements
Drivers who operate commercial motor vehicles (CMV) to deliver propane must meet
all of the U.S. Department of Transportation (DOT) Licensing and driving
requirements. Before driving a CMV, employees must obtain there commercial
driver’s license (CDL) and additional required endorsements from their state
driving agency. Propane delivery vehicle drivers must also be aware of other
driving requirements and restrictions, including rules prohibiting drug and
alcohol use.
A road side stop performed by highway enforcement personnel is a bad time to

Understanding Bulk Plant Tank Connections, Valves, and Gauges
The propane bulk plant is a specialized and
complex facility where large quantities of propane are received, stored and
prepared for delivery, where several tanks of various sizes may be installed
depending on the needs of retailers and customers.
Bulk plants tanks have several valves and gauges installed in either end, and in
the top and bottom of the tank.
It is important that those responsible for operating and maintaining bulk tanks
understand the location and of the valves and gauges, as well as their purposes.
With the proper education and training, new plant operators can effectively
understand these critical functions and become valued employees.

Container Distance Requirements
The National Fire Protection Association pamphlet 58 (NFPA 58) provides minimum
distance requirements for setting various types of propane containers on a
customer’s property.
These distance requirements pertain to ignition sources, vent/air intakes,
building openings below level of (propane gas) discharge, and property
lines/important buildings.
Many of the distance requirements vary with the type of container being set,
such as an underground ASME tanks, DOT stationary cylinders, and above ground
ASME tanks of varying capacities.

Products of Complete and Incomplete Combustion
Combustion is a chemical
reaction that changes a fuel source, such as propane, into a useful form of
energy, such as heat. Combustion requires all three ingredients: fuel, oxygen,
and an ignition source. However, all three ingredients must be present in the
proper proportions for combustion to occur. If a mixture of gas and air contains
more gas than is needed for ideal combustion, then it is
referred to as a rich burn. If a mixture of gas and air
contains less gas than is needed for ideal combustion, then it
is referred to as a lean burn.
The ideal combustion ration (“complete combustion”) for propane is 1 part
propane (4%) to 24 parts of air (96%). Even at this ideal ration, combustion
products, known as flue gases, still occur. However, under this scenario, those
products are harmless carbon dioxide and water.
Incomplete combustion (due to either rich or lean burns) may produce harmful
combustion by-products such as carbon monoxide and aldehydes.
Most appliance burners are designed to burn a gas mixture that is as close to
the ideal (4% propane) as possible, and may be regularly inspected by a
qualified technician to ensure the maintenance of the ideal burn ratio.

Practices to view how combustion products are affected by different fuel to gas
ratios.

Filling
Customer Containers Squirting Propane Liquid Fixed
Maximum Liquid Gauge vs. Float Gauge
What Would You Do?
Before filling the customers tank, this dedicated propane professional positions
the bobtail, performs a site inspection, checks the liquid level in the
container, sets the meter, opens the valves, and engages the PTO. He then
prepares the hoses and filler valve, connects the hoses and checks for leaks and
begins to fill the customer’s container.
As he monitors the filling process, he notices that the fixed maximum liquid
level gauge is squirting propane liquid, but the float gauge only shows a
reading of 70%.

Vehicle Inspections: Post -Trip
DOT requires
commercial motor vehicle (CMV) drivers to perform pre-trip and post-trip
inspections to determine that the vehicle is in safe operating condition before
driving it on public roadways.
These inspections are critical for discovering damaged or missing parts, and
other problems that could cause an accident, break down, or delay of your trip.
Post-trip inspections are more comprehensivPost-trip inspections are more comprehensive than pre-trip inspections and have
reporting requirements that affect the pre-trip inspection and can alert the
driver to problems that may have developed during the day.
DOT requires CMV drivers to prepare a written Driver Vehicle Inspection Report
(DVIR) for each vehicle operated during the work day. During the Post Trip
Inspection, the CMV driver must examine and document the DVIR, the condition of
vehicle parts and accessories, and report any defects that would result in the
unsafe operation of the CMV or break down.

Performing Scheduled Bobtail Inspections
The US Department of Transportation (DOT) requires bobtail drivers to inspect
their vehicles before operating them each day. Daily “walk around” inspections
of your bobtail after loading at the bulk plant minimizes the risk for system or
documentation issues when arriving at the delivery site.
In addition, vehicles must undergo monthly, annual, and five-year inspections,
each of which has its own inspection criteria.

Personal Protective Equipment in the Propane Industry
A job that is properly planned for before it
begins is critical to avoiding mishaps that can lead to emergency situations.
Effective job planning takes into consideration the safety of the worker,
customers, and public.
Personal protective equipment (PPE) and procedures for training employees on its
proper use is a critical step towards workforce safety.
Based on hazard assessments, the proper use of PPE such as gloves, hard hats,
safety shoes, eye protection, shields, respirators, etc., are important in
reducing and eliminating on-the-job injuries, the costs associated with those
injuries, and establishing compliance with rules established by the Occupational
Safety & Health Administration (OSHA).
OSHA regulations require the use of PPE during operations that present the risk
of injuries to employees that cannot be controlled by engineering or process
procedures. OSHA requires the employer to:
- Determine the use and selection of PPE
- Train employees on the proper use and care of PPE
- Document employee use and care of PPE
In return, employees are required to properly utilize and care for the PPE that
has been assigned.

Effects of Temperature and Pressure: Part 1: Propane
Vapor Demand
Understanding the effects that heat and pressure have on liquid propane
is critical to understanding how propane behaves.
Propane is affected by heat and pressure in much the same way as water. At
atmospheric pressure the boiling point of propane is -44Fo. At any temperature
below that a pool of propane will remain in liquid form, because its vapor
pressure is less than atmospheric. At temperatures above -44Fo, the vapor
pressure of propane is greater than atmospheric pressure, therefore the liquid
will vaporize.
Keeping this in mind, when the valve of a propane appliance is open, propane
will flow to the burner, and the demand for gas vapor will immediately cause a
slight drop in pressure inside the container. This upsets the heat/pressure
balance and causes the propane to begin boiling off vapor to replace the vapor
going into the burner.
As long as the demand for propane remains, the propane will continue to boil,
supplying fuel to the burner.
When the valve on the appliance is closed, the propane will stop flowing and
return to its balance point. The boiling will eventually stop as the balance is
reached.

interactive learning on Propane Vapor Demand.

Safe Driving Techniques: Cell Phones
Do your drivers know what to do if their cell phone rings while they’re driving?
As a propane delivery driver, you are responsible for protecting both people and
property and it is not enough to just drive defensively. You must also be
prepared to respond appropriately to dangerous and unexpected situations.
Vehicle accidents and emergencies are particularly dangerous for propane drivers
and the general public because of the chance of a hazardous material leak or
fire. Propane companies have always been committed to the safe and secure
handling and transporting of hazardous materials and in CETP there are great
case studies and learning activities to re-enforce safe driving techniques.
