Welcome to…
Health Hazards in Construction
Construction & utility workers are
exposed to a variety of health hazards
everyday. These men and women
have the potential for becoming sick,
ill and disabled for life.
Learn the health hazards on your job
and know how to protect yourself…
Sadly, these health hazards (e.g.,
dangerous dust and other chemicals)
can be unexpectedly brought home…
3
Learning Objective
TLO:Comply with OSHA’s new Hazard Communication
Standard (HCS) and function within the Globally
Harmonized System of Classification & Labeling of
Chemicals.
4
Learning Objective
EO: Identify the purpose, scope, benefits, elements and effective
dates of GHS.
EO: Compare and contrast GHS with HCS.
EO: Define the 16 physical and 10 health hazard classifications.
EO: Describe the requirements of a 16-section SDS.
EO: List the new label requirements.
EO: Identify controls to eliminate and/or reduce exposure to
hazards.
5
Effective Dates
• Dec. 1, 2013 – Train employees on the new label
elements and SDS format.
• Dec. 1, 2015 – Shipment of products with old system
ends.
• June 1, 2016 – Full implementation.

that incorporates the use of
labels with color-coded
bars.
• A special code identifying
appropriate personal
protective equipment (PPE)
is also listed.
