    Coverage and Definitions
  • 1910.124 General Requirements for Dipping
    and Coating Operations

6

    and Coating Operations that use Flammable
    or Combustible Liquids
  • 1910.126 Additional Requirements for Special
    Dipping and Coating Operations

7
Definitions
  • Hazardous Chemical
  • Occupational Safety Health Act (OSHA) term that
    denotes any chemical that would be a risk to
    employees if exposed in the work place

8
Definition
  • Highly Hazardous Chemical
  • OSHA term that denotes any chemical that would
    posses toxic, reactive, flammable or explosive
    properties

9
Definitions
  • Aerosol
  • Aerosol shall mean a material which is dispensed
    from its container as a mist, spray, or foam by a
    propellant under pressure

10
Definitions
  • Container
  • Container shall mean any can, barrel, or drum

11
Definitions
  • Closed Container
  • Closed container shall mean a container so sealed
    by means of a lid or other device that neither
    liquid or vapor will escape from it at ordinary
    temperatures

12
Definitions
  • Fire Area
  • Fire area shall mean an area of a building
    separated from the remainder of the building by
    construction having a fire resistance of at least
    1 hour and having all communicating openings
    properly protected by an assembly having a fire
    resistance rating of at least one hour.

13
Definitions
  • Flash Point
  • Flash point means the minimum temperature at
    which a liquid gives off vapor within a test
    vessel in sufficient concentration to form an
    ignitable mixture with air near the surface of
    the liquid. The flash point is normally an
    indication of susceptibility to ignition.

14
Definitions
  • Combustible Liquid
  • Combustible liquid means any liquid having a
    flash point at above 100F (37.8 C).
  • Combustible liquids are divided into two classes
  • Class II
  • Class III

15
Definitions
  • Flammable Liquid
  • Flammable liquid means any liquid having a flash
    point below 100 F (37.8 C) or higher, the total
    of which make up 99 percent or more of the total
    volume of the mixture.

16
Definitions
  • Portable Tank
  • Portable tank shall mean a closed container
    having a liquid capacity over 60 U.S. gallons and
    not intended for fixed installation

17
Definitions
  • Safety Can
  • Safety can means an approved container, of not
    more than 5 gallons capacity, having a
    spring-closing lid and spout cover and so
    designed that it will safely relieve internal
    pressure when subject to fire exposure

18
Flammable (Explosive) Limits
  • Flammable Range
  • The range of a combustible vapor or gas-air
    mixture between the upper and lower flammable
    limits.
  • Also, known as the explosive range.

19
Flammable (Explosive) Limits
  • Lower Flammable Limit
  • The lowest concentration at which a combustible
    gas forms a flammable mixture.
  • Below the LFL there is too little combustible
    fuel to sustain a flame.
  • Also, known as Lower Explosive Limit or LEL.

20
Flammable (Explosive) Limits
  • Upper Flammable Limit
  • The highest concentration at which a combustible
    gas forms a flammable mixture.
  • Above the UFL there is too little oxygen to
    sustain a flame. Better known as too rich to
    burn.
  • Also, known as Upper Explosive Limit or
    UEL.

21
Flammable (Explosive) Limits
  • Hazardous Material LFL UFL
  • Butane 1.9 8.5
  • Ethylene Oxide 3.0 100.0
  • Gasoline 1.4 7.6
  • Hydrogen 4.0 75.0
  • Isopropyl Alcohol 2.0 12.7
  • Propane 2.1 9.5

22
Container and Portable Tank Storage
  • This section applies only to the storage of
    flammable and combustible liquids in drums or
    other containers not exceeding 60 gallons
    individual capacity and portable tanks of less
    than 660 gallons individual capacity.

23
Fire Control
  • At least one portable fire extinguisher having a
    rating of not less than 12-B units shall be
    located outside of, but not more than 10 feet
    from, the door opening into any room used for
    storage.
