Injecting methanol into propane storage
containers, thinning and applying protective
coatings to containers and cleaning machinery
parts using de-greasing solvents are examples of
tasks that require the handling and movement of
flammable or combustible liquids. It is
essential to know and understand safe handling
practices for these and other circumstances.
In this module you will learn to identify (1)
Codes and standards that apply to handling
flammable and combustible
liquids (2) The proper use of personal protective
equipment (PPE) for handling
flammable and combustible liquids (3) Guidelines
for the proper handling of flammable and
combustible liquids

Handling Flammable Combustible Liquids

• Personal Protective Equipment (PPE)
• To determine the PPE recommended for a particular
  chemical, you should read the manufacturers
  Material Safety Data Sheet (MSDS).
• In addition to PPE guidelines, you should consult
  the sections that detail fire, health and safety
  risks. You should also be familiar with first
  aid, fire prevention and fire-fighting measures
  that apply.

Handling Flammable Combustible Liquids

• Indoor Storage
• Use only properly labeled original shipping
  containers or containers approved for the liquid.
  
• Store only in approved ventilated metal storage
  cabinets labeled to identify the contents as
  flammable.

Handling Flammable Combustible Liquids

• Outdoor Storage
• Bulk quantities of flammable and combustible
  liquids may be stored in approved bulk storage
  tanks, or in metal drums.
• Outdoor storage areas or tanks should be at least
  20 feet away from propane transfer areas, and
  should be isolated from sources of ignition and
  other combustible materials.
• Drums and bulk tanks must be labeled to indicate
  their contents, and the hazards associated with
  the stored liquid.

Handling Flammable Combustible Liquids

• Transferring Flammable Combustible Liquids
• Liquid storage drums should be electrically
  grounded. Grounding may be by individual
  electrical wire (typically 10 or 12 wire gauge)
  to a grounding stake, or by electrical connection
  to a common grounding strip that is electrically
  grounded.
• If metal safety cans are used, an electrical bond
  should connect the safety can and the storage
  drum.
• The transfer area should be isolated from
  potential ignition sources.
• The person making the transfer should wear proper
  PPE throughout the transfer operation.

Handling Flammable Combustible Liquids

• Transferring Flammable Combustible Liquids
• Receiving containers should be approved for the
  liquid transferred and labeled to indicate the
  contents. The label should state the common name
  of the liquid, such as, GASOLINE, METHANOL,
  NAPTHA, PAINT THINNER, etc. This does not apply
  if the contents will be used in the same shift
  and is under the control of the individual who
  filled the un-labeled container.
• Care should be taken to avoid liquid spills and
  ground contamination. Any spill should be
  cleaned up following company spill and disposal
  procedures.

10
Handling Flammable Combustible Liquids

• Transporting Flammable Combustible Liquids
• Limited quantities of these liquids may be
  transported as materials of trade.
• Containers must be leak tight for liquids and
  gases, sift proof for solids, and be securely
  closed, secured against movement, and protected
  against damage.
• Each material must be packaged in the
  manufacturer's original packaging, or a
  container of equal or greater strength and
  integrity.
• A non-bulk packaging other than a cylinder
  (including a receptacle transported without an
  outer packaging) must be marked with a common
  name or proper shipping name to identify the
  material it contains, including the letters
  RQ'' if it contains a reportable quantity of a
  hazardous substance.

11
Handling Flammable Combustible Liquids

• Transporting Flammable Combustible Liquids
• The maximum quantity for a Hazard Class 3 or 8
  material designated as Packing Group II or
  Packing Group III (such as methanol, gasoline, or
  paint) is 66 pounds or 8 gallons.
• The aggregate gross weight (including the weight
  of the containers) of all materials of trade on a
  motor vehicle may not exceed 440 pounds.
• Hazardous materials of trade should not be
  transported in the cab instead, they should be
  secured in cargo areas or auxiliary equipment
  storage boxes.
