Hello,
this is now my fifth blog of the public health and emergency response class. We
are about half way through the course and as of now I am really enjoying the
class. The lectures are interesting and I love how interactive the class is.
Anyway, the fifth blog is all about confined spaces. With just looking at the
phrase “Confined Spaces” I think about it being a very small place. With one
entry point. I feel like confined spaces also only have one entrance and exit.
Many workplaces contain areas that
are considered "confined spaces" because while they are not designed
for people, they are large enough for workers to enter and perform certain
jobs. A confined space also has limited or restricted means for entry or exit
and is not designed for continuous occupancy. Confined spaces include, but are
not limited to, tanks, vessels, silos, storage bins, hoppers, vaults, pits,
manholes, tunnels, equipment housings, ductwork, pipelines, etc.
OSHA uses the term "permit required space" (permit space) to describe a confined space that has one
or more of the following characteristics: contains or has the potential to
contain a hazardous atmosphere; contains material that has the potential to
engulf an entrant; has walls that converge inward or floors that slope downward
and taper into a smaller area which could trap or asphyxiate an entrant; or
contains any other recognized safety or health hazard, such as unguarded
machinery, exposed live wires, or heat stress.
Many
workers are injured and killed each year while working in confined spaces. An
estimated 60% of the fatalities have been among the would-be rescuers. A
confined space can be more hazardous than regular workspaces for many reasons.
To effectively control the risks associated with working in a confined space, a confined space hazard assessment and Control Program should be implemented for
your workplace. Before putting together this program, make sure to review the
specific regulations that apply to your workplace. All jurisdictions within
Canada have regulations dealing with confined space entry. The regulations can
vary slightly from jurisdiction to jurisdiction.
Confined
spaces can be below or above ground. Confined spaces can be found in almost any
workplace. A confined space, despite its name, is not necessarily small.
Examples of confined spaces include silos, vats, hoppers, utility vaults,
tanks, sewers, pipes, access shafts, truck or rail tank cars, aircraft wings,
boilers, manholes, manure pits and storage bins. Ditches and trenches may also
be a confined space when access or egress is limited. All hazard found in a
regular workspace can also be found in a confined space. However, they can be
even more hazardous in a confined space than in a regular worksite.
The
important thing to remember is that each time a worker plans to enter any work
space, the worker should determine if that work space is considered a confined
space. Be sure the confined space hazard assessment and control program has been
followed.
In
conclusion, confined spaces are way more dangerous than a regular work space. To
