understanding now let's start module 3
it is divided into two sections module
3A 29 CFR 1910 subpart Z module 3 B
ocean 1926 subpart
D at first we will first discuss module
3A which is about 29 CFR 1910 subpart Z
health hazards in construction and
Hazard
communication the hazard communication
standard HCS informs workers and
employers about various chemical hazards
in the workplace and what protective
measures they can take to prevent the
adverse effects of such hazards
this section gives you a basic
understanding of dealing with hazardous
chemicals and how workers can prevent
and protect themselves from chemical
hazards the module is comprised of the
following two
lessons first introduction to the hazard
communication standard second labels
msdss symbols hazards and
training let's memorize the essential
key terms chemical any element compound
or mixture of el elements and or
compounds combustible a material having
a flash point of 100° F or above
flammable a material having a flash
point below 100° F hacom Hazard
communication standard inhalation
breathing in an airborne substance
including gases fumes Mists Vapors dust
or
aerosols training a course of study in
which employees are instructed to
identify and work safely with hazardous
materials let's start with the first
lesson introduction to the hazard
communication
standard the key points are exposure
means that an employee is subjected as a
condition of employment to a chemical
that is a physical or health hazard
including potential accidental or
possible exposure subjected regarding
health hazards includes any entry route
inhalation ingestion skin contact
absorption or
injection a hazard warning means any
words pictures symbols or combination
there of appearing on a label or other
appropriate form of warning that conveys
the specific physical and health hazards
including Target organ effects of the
chemicals in the
containers immediate use means that the
hazardous chemical will be controlled
and used only by the person who
transfers it from a labeled container
and within the workshift in which it is
transferred
any hazardous material decanted pumped
from a primary to a secondary container
should have the labeling information
transferred to the secondary
container organic peroxide is any carbon
containing compound with two oxygen
atoms joined
together pyrophoric means a chemical
will ignite spontaneously in air at a
temperature of 130° fight 54.4 de C or
below an unstable
reactive chemical is one that in its
pure state or is produced or transported
will vigorously polymerize decompose
condense or become self-reactive under
shock pressure or temperature
conditions a water reactive chemical
reacts with water to release a gas that
is either flammable or presents a health
hazard in last workers need and have the
right to know about the hazards and
identities of the chemicals they are
exposed to when performing their their
tasks and
duties now look at the study
questions let's move to the second
lesson labels msdss symbols hazards and
training the key points are all
hazardous chemical containers must be
labeled as labels are considered the
most immediate source of information
about chemicals and their Hazard
potential many chemical manufacturers
including CL safe handling procedures on
labels even so the employer must
translate the information on the MSDS
into an understandable format and convey
the hazards associated with working with
any hazardous materials in the facility
before an employee is exposed to the
hazard hazardous chemical manufacturers
or importers must update msdss within 3
months of discovering new important
information about chemical
hazards when working with materials
labeled with a D hazard class shipping
label you should be aware that this
represents a specific hazard the
materials MSDS provides information
regarding particular hazards denoted by
dot
labels employees must be trained before
working with materials that represent a
hazard water reactive materials react
with water and can explode furthermore
unstable reactive materials can react or
become self-reactive when exposed to
pressure temperature or
shock monitor yourself and co-workers
for symptoms such as dizziness eye or
throat irritation and skin rashes that
might indicate exposure to a hazardous
material or chemical if these or other
symptoms appear report them to your
supervisor
immediately lastly always use gloves
aprons masks or other PPE whenever
called for on a label or
MSDS now look at the study questions
[Music]
in this section we will discuss module
3B which is about ocean 1926 subpart d
health hazards in
construction this section caters to
individuals employed in the construction
industry who come in contact with health
hazards and chemicals while performing
their duties this section emphasizes the
subjects covered in OSHA 29 CFR 1926
subpart D let's memorize essential key
terms container any bag Barrel bottle
box can cylinder drum reaction vessel
storage tank that contains a hazardous
chemical explosive a chemical that
causes a sudden almost instantaneous
release of pressure gas and heat when
subed to sudden shock pressure or high
temperature physical hazard a chemical
for which there is scientifically valid
evidence that it is a combustible liquid
a compressed gas explosive flammable an
organic peroxide an oxidizer pyrophoric
unstable reactive or water reactive
trade secret any confidential formula
pattern process device information or
compilation of information that is used
in an employer's business and allows the
employer to obtain an advantage over
competitors who do not know or use it
[Music]
let's start the lesson about hazardous
materials the key points
are employee exposure to silica dust
brethable quartz must not exceed 0.1
microgram cubic meter averaged over an
8-hour
workshift silicosis can disable a person
in many ways making breathing difficult
and painful silicosis may also cause
death or turn into lung cancer symptoms
usually associated ated with silicosis
include loss of appetite fevers and body
weight
loss exposure by inhaling loose asbestos
fibers can cause disabling or fatal
diseases such as gastrointestinal cancer
cancers of the lung or lung cavity
lining and severe lung impairment
asbestosis the symptoms of these
diseases generally do not appear for 20
or more years after initial
exposure short-term exposure must also
be limited to not more than one fiber
per cubic meter averaged over 30 minutes
rotation of employees to achieve
compliance with either permissible
exposure limit PL is
prohibited even workers families and
friends can be at risk as asbestos can
often be carried on clothing it is
important to note that workers are only
sometimes told they are working around
asbes and even single exposures to very
low doses of fibers can result in
harm no employee may be exposed to MDA
above the permissible exposure limit PL
of 10 parts per billion ppb as an 8h
hour time weighted average TW wa or
above a short-term exposure limit STL of
100 ppb over a 15minute sampling
period decontamination areas must also
be established outside of but as near as
practical to the regulated area for
workers materials and Equipment
contaminated with MDA the
decontamination area must include
equipment storage wash and clean change
areas lastly lead is most commonly taken
into the body by inhalation when workers
breathe and Lead is dust fume or Mist
their lungs and upper respiratory tract
absorb the lead into the body they can
also absorb lead through the digestive
system if it enters the mouth and is
ingested now look at the study
questions if if you have any questions
write them in the comment section we
will resume with module 4 in the next
