– New requirements for, Fire Prevention and
Suppression Procedures during hot work
operations. (NFPA) 51B-2009, replaced (NFPA)

NFPA 51B, 2009 Edition
Fire Prevention During Welding, Cutting, and Other Hot Work
• The new 2009 NFPA 51B was released early this year
changing the 2003 edition for fire prevention during
hot work. One of the major changes to 2003 NFPA
51B is the recognition of ANSI/FM 4950 fabric testing
standard into the 2009 NFPA 51B edition.
• Prior to ANSI/FM 4950, the 2003 NFPA 51B
recommended only “heat-resistant tarpaulins”, a
vague term that allowed fabrics made of untested,
non-rated materials to be used for fire protection,
increasing the risk of fire during hot work operations.
NFPA 51B
Standard for Fire Prevention During Welding, Cutting,
and Other Hot Work
2009 Edition
Reference: A.3.3.7, A.3.3.8, and A.3.3.9 (New)
• A.3.3.7 Welding Blanket. Welding blankets are
required to be listed or approved or equivalent for
such use. One such listing includes ANSI FM4950,
Welding Pads, Welding Blankets and Welding
Curtains for Hot Work Operations.

A.3.3.8 Welding Curtains. Welding curtains are
required to be listed or approved or equivalent for
such use. One such listing includes ANSI FM4950,
Welding Pads, Welding Blankets and Welding
Curtains for Hot Work Operations.
• A.3.3.9 Welding Pads. Welding pads are required to
be listed or approved or equivalent for such use. One
such listing includes ANSI FM4950, Welding Pads,
Welding Blankets and Welding Curtains for Hot Work
Operations
Definitions
• Welding Blanket: ANSI/ASC Z49.1-94 ANSI/FM 4950
– A heat-resistant fabric designed to be placed in the vicinity of a hot
work operation. Intended for use in horizontal application with light to
moderate exposures
• Welding Curtain: ANSI/ASC Z49.1-94 ANSI.FM 4950
– A heat resistant fabric design to be placed in the vicinity of hot work
operation. Intended for use in vertical applications.
• Welding Pad: ANSI/ASC Z49.1-94 ANSI/FM 4950
– A heat-resistant fabric designed to be placed directly under a hot work
operation such as welding or cutting, intended for horizontal
application with exposure resulting from molten substances or heavy
welding.

In general, welding pads, welding blankets and welding curtains are
evaluated on their ability to:
prevent burn through of the material and provide adequate protection
for adjacent combustibles from possible sources of ignition.
limit temperature transmission through the material to a degree that
will prevent ignition to underlying combustibles.
resist melting, dripping or deformation so as to prevent sparks from
spreading outside of confined and protected areas.
maintain their flexibility, durability and structural integrity when
charred areas are subjected to 90bends.
maintain their fire and temperature rise resistance properties when
subjected to accelerated weathering tests intended to simulate
exposure to light and water (ultra violet [uv] and condensation,
respectively) conditions.
Certification Mark
All approvals are not the same.
• ASTM E -662 -09 – Standard Test method for specific optical density of
smoke generated by solid materials
• ASTM E-84 – Standard test method for surface burning Characteristics of
Building Materials.
• ASTM D-298-10 – Standard Practice for Accelerated weathering of FireRetardant-Treated Wood for Fire Testing.
• NFPA 701 – Standard Method of Fire Test for Flame propagation of
Textiles and Films
• California Fire Marshall – Issue certificates of registration for approved
flame retardant chemicals for nonflammable materials and treated
fabrics. General usage is for places of public assembly and schools,
requiring decorative materials and fabrics ( curtains, drapes, drops,
hangings and tents, awnings or fabric enclosures).
Nationally Recognized Testing Laboratory
(NRTL)
• FM Approval is only recognized
testing facility for Weld
Blankets, Curtains and Pads.
Why FM 4950
• During a 10 year study, one out of every 20 fire losses
reported by FM Global clients started by improperly managed
hot work, each being preventable.
• Hot work is one of the three most common causes of fires at
FM Global-insured properties. During the 10-year period, FM
Global experienced 385 recorded hot work losses for a
staggering gross dollar amount of more than US $739
million—or an average of US $1.4 million per loss.
• A leading cause of fire in Hot Work was the use of inadequate
welding materials used to prevent fire in hot work operations.
