be released
1
BD’s physical hazards

Flammable gas

Explosive peroxides

Fire hazard when exposed to heat,
flame, or strong oxidizers

Release of toxic gases such as
carbon monoxide during a fire
2
BD’s health hazards
 Exposure
from inhalation of gas
or contact with liquid
 Overexposure
can cause
respiratory and eye irritation
 Contact
with liquid BD can
cause burns and frostbite

 Nausea
 Fatigue

 Decreased blood pressure
 Decreased pulse rate
 Unconsciousness


4a
OSHA regulation of 1,3Butadiene
 Time-weighted
average (TWA)
permissible exposure limit (PEL)
is 1 part per million (ppm)
 Short-term
exposure limit
(STEL) is 5 ppm
4b
OSHA regulation of 1,3Butadiene
 Action
level is 0.5 ppm as an 8hour TWA
 Meeting
or exceeding action
level requires additional
standards to be followed
 Access
to BD
standard
4c
Material safety data
sheets (MSDS)
 Where
they are kept
 What
information
is included
5
Labeling requirements
for containers of BD
 All
BD containers must have
legible labels and contain the
following information
6
Exposure monitoring to
determine employee exposures

Monitoring is required unless
objective data demonstrates that BD
will not be released in levels at or
above the action level or above the
STEL
7a
Exposure monitoring to
determine employee exposures
 Affected
employees and their
representatives have the right
to observe any exposure
monitoring
 Affected
employees must be
informed of monitoring results
within 5 working days of receipt
7b
Exposure monitoring to
determine employee exposures

Within 15 working days of receipt of
results, employees must be informed
of the corrective actions being taken
to reduce any exposures to below
the PEL or STEL
7c
Engineering controls
limit exposure to BD
 Examples
of engineering
controls used in our workplace
8
Work practices and
procedures
 Never
eat, drink, or smoke
where BD is used, stored, or
handled
 Do
not keep food, beverages, or
smoking materials in these
areas
9a
Proper storage and
handling
 Tightly
close cylinders and
containers
 Protect
cylinders from damage
 Outside
or detached storage is
preferred
 Inside
storage should be in a
cool, dry, well-ventilated,
noncombustible area
9b
Proper storage and
handling
 BD
in storage should be
checked for proper inhibitor
content, for self-polymerization,
and for formation of peroxides
when in contact with air and
iron
 Avoid
contact with copper and
copper alloys. Explosive copper
compounds can form
9c
Proper storage and
handling
 Store
away from flammables,
combustible materials, and
oxidizing materials
 Store
away from sources of
ignition
 Store
cylinders vertically
9d
Work practices and
procedures



All electrical installations and
equipment used in areas where BD is
present must be rated for a Class I
hazardous location
Waste BD is classified as a
hazardous waste due to its
flammability characteristics
Other safe work practices at our
facility
9e
Regulated area
 An
area where the exposure or
potential exposure to BD
exceeds 1 ppm as an 8-hour
TWA or 5 ppm as a 15-minute
STEL
10
Signs posted to mark
regulated areas
 Limit
entry into regulated areas
 Prohibit
drinking
smoking, eating, and
11a
Signs posted to mark
regulated areas
 Warn
of BD’s potential cancer
hazard
11b
Signs posted to mark
regulated areas
 Alert
employees that
respiratory protection is
required when exposure may
exceed the PELs for 8-hour TWA
or STEL
11c
Personal protective equipment
(PPE) requirements

Necessary if the use of engineering
and work-practice controls does not
reduce exposure to levels at or
below BD’s PELs

Employees are required to use it
properly

Our PPE requirements
12
Respiratory protection
required
 When
exposure exceeds 1 ppm
as an 8-hour TWA or 5 ppm as a
15-minute STEL
 During
installation or set up of
engineering and work-practice
controls
13a
Respiratory protection
required
 During
non-routine, infrequent
operations when exposures are
limited in duration
 In
operations where engineering
and work-practice controls are
not sufficient to reduce
exposures to or below the PELs
13b
Respiratory protection
 Types
 Care
of respirator we use
of respirators
13c

surveillance program schedule


Upon reassignment to an area where
