Write short notes on any four of the following:
1. Role of
Environmental Laboratories in environment protection
Answer :
2. Zoning Concept and
Emergency Planning
Answer : Zoning is a device of land-use planning used by local governments
in most developed countries.The word is derived from the practice of
designating permitted uses of land based on mapped zones which separate one set
of land uses from another.
Zoning may be use-based
(regulating the uses to which land may be put, also called functional zoning),
or it may regulate building height, lot coverage (density), and similar
characteristics, or some combination of these.
Similar urban planning methods
have dictated the use of various areas for particular purposes in many cities
from ancient times.
3. ALARP concept of
risk management
Answer : Using “reasonably practicable” allows us to
set goals for duty-holders, rather than being prescriptive. This flexibility is
a great advantage but it has its drawbacks, too. Deciding whether a risk is
ALARP can be challenging because it requires duty-holders and us to exercise
judgement. In the great majority of cases, we can decide by referring to
existing ‘good practice’ that has
been established by a process of discussion with stakeholders to achieve a
consensus about what is ALARP. For high hazards, complex or novel situations,
we build on good practice, using more formal decision making techniques,
including cost-benefit analysis, to inform our judgement.
4. Ergonomic hazards
Answer : An ergonomic hazard is when the
musculoskeletal system is affected by a physical factor that is within the
environment that you are in. Carpel tunnel syndrome is a response to an
ergonomic hazard. This syndrome is cause from a repeated motion that takes
place when a person is typing. There are a few things that can be considered an
ergonomic hazard. A chair and lighting are a couple of examples. Both of these
things can affect the musculoskeletal system if not used properly.
The term “ergonomics” can simply
be
5. Differences between
active and latent failure
Answer : The terms active and
latent as applied to errors were coined by James Reason. Active errors occur at the point of contact between a human and
some aspect of a larger system (e.g., a human–machine interface). They are
generally readily apparent (e.g., pushing an incorrect button, ignoring a
warning light) and almost always involve someone at the frontline. Active
failures are sometimes referred to as errors at the sharp end, figuratively
referring to a scalpel. In other words, errors at the sharp end are noticed
first because they are committed by the person closest to the patient. This
person may literally be holding a scalpel (e.g., an orthopedist operating on
the wrong leg) or figuratively be administering any kind of therapy (e.g.,
Section B (30 marks)
(Attempt any three)
1. What factors are
needed to be considered in managing health & safety in power sector?
Answer : Strategy development
culminated in a key workshop including Board Members, Workers Council Members,
senior managers and a range of health and safety experts achieving wide
understanding, commitment and motivation.
Electricity provision must have
regard to minimising environmental and public health effects, both directly
from generation and indirectly from obtaining fuels and dealing with wastes.
With nuclear power the focus is
on uranium mining and nuclear wastes.
The health and environmental
costs of nuclear power are very low relative to the main alternatives.
2. What are the
essential elements of a successful health, safety and environmental management
system which help to organize an effective and efficient HSE management?
Answer :
3. Identify the causes
for accidents in a factory. What steps should be taken to ensure industrial
safety?
Answer : Factory workers are
responsible for the manufacturing and construction of almost every kind of
product that you can think of. Unfortunately, these industrious workers also
have one of the highest rates of workplace injury and death because of their
exposure to heavy machinery, toxic and flammable chemicals, extreme
temperatures, and other potential dangers.
Causes of Factory Accidents
Factory accidents may happen for
a number
4. Elucidate upon the
nature and causes of occupational health conditions in the developing
countries.
Answer : Workers around the
world—despite vast differences in their physical, social, economic, and
political environments—face virtually the same kinds of workplace hazards.
These hazards are traditionally categorized into four broad types: chemical,
biological, physical, and psychosocial. What emerges from our incomplete
knowledge of their risk, however, is that the more than 80 percent of the
world's workforce that resides in the developing world disproportionately
shares in the global burden of occupational disease and injury. Several classic
occupational diseases, such as silicosis and lead poisoning, that have been
