HAZWOPER 40 - Lesson 4: Hazard Recognition Exam
2025 Questions And Correct Answers Already Graded
A+
Lesson Description - ✔✔ANSWER ✔✔-This lesson, Hazard
Recognition, addresses both chemical and biological hazards that
can be encountered in the hazardous waste site environment.
How to do a job safety analysis (JSA) is explained in detail because
this is how employers identify hazards that need to be controlled.
This lesson explains the hazard identification systems like NFPA
signage and DOT package labels that must be used to alert
workers of present or potential danger. Finally, a detailed
discussion of common environmental and biological hazards is
given. This section effectively alerts employers and workers to
specific dangers and lists ways to protect against them.
Learning Objectives - ✔✔ANSWER ✔✔-At the completion of this
lesson, you will be able to:
, Distinguish between National Fire Protection Association (NFPA)
and Department of Transportation (DOT) insignia.
Summarize the meaning of the NFPA 704 System.
Name common chemical physical hazards.
Discuss the two viruses of greatest concern in the workplace.
Explain the objectives of an Exposure Control Program (ECP).
Introduction - ✔✔ANSWER ✔✔-When employees might be
exposed to hazardous substances as part of their duties,
prevention must include protection from physical harm as well.
Other concerns include allergic reactions, overheating, oxygen
deficiency, or even shock or electrocution. Material Safety Data
Sheets (MSDSs), proper labeling, and employee awareness go a
long way toward addressing such issues as improper substance
handling, mere careless, or accidental chemical exposure, mixture,
or friction that could result in fire or explosion. Even the
introduction of water or temperature change is enough to cause
reactions in some instances, so safety and training go hand in
hand.
Lesson Focus - ✔✔ANSWER ✔✔-This lesson focuses on the
following topics:
Hazard Recognition Definitions
, Hazard and Safety Analysis
Hazard Recognition
Chemical Health Hazards
Site and Equipment Hazards
Environmental Hazards
Biological Hazards
Hazard Recognition Definitions - ✔✔ANSWER ✔✔-Before
discussing how to identify and handle hazards at a waste site, it is
important to understand some key definitions.
A hazard is any substance, situation, or condition that is capable
of harming human health, property, or the environment. It
represents a potential for harm.
A risk is a measure of the probability and severity of a hazard to
harm human health, property, or the environment.
Safety is a judgment about the acceptability of risk. A Site Health
and Safety Officer is responsible for assessing the potential risk of
a hazard, if the level of risk is acceptable, and if something needs
to be done to lower the risk.
