CHAPTER 6 DISCUSSION
INTRODUCTION
Hierarchy
of hazard control is a system used in industry to minimize or eliminate
exposure to hazards.It is a widely accepted system promoted by numerous safety
organizations. This concept is taught to managers in industry, to be promoted
as standard practice in the workplace. Various illustrations are used to depict
this system, most commonly a triangle.
ELIMINATION
ACTION
Eliminating
the hazard—physically removing it—is the most effective hazard control. For
example, if employees must work high above the ground, the hazard can be
eliminated by moving the piece they are working on to ground level to eliminate
the need to work at heights.
SUBSTITUTION
ACTION
Substitution,
the second most effective hazard control, involves replacing something that
produces a hazard (similar to elimination) with something that does not produce
a hazard—for example, replacing lead-based paint with acrylic paint. To be an
effective control, the new product must not produce another hazard. Because
airborne dust can be hazardous, if a product can be purchased with a larger
particle size, the smaller product may effectively be substituted with the
larger product.
ISOLATION ACTION
This control involves separating the hazard or
hazardous work practice from employees other work areas. This may involve
sectioning off the area by erecting barriers or by relocating either the
hazardous work practice or the „other‟ employees and their work practices—for
example:
• Risk: Excessive noise emanating from machinery.
• Control: Enclosing the machinery or the personnel
hence creating an isolating barrier between the hazard and the person by using
a barrier.
ENGINEERING CONTROL ACTION
The
third most effective means of controlling hazards is engineered controls. These
do not eliminate hazards, but rather isolate people from hazards. Capital costs
of engineered controls tend to be higher than less effective controls in the
hierarchy, however they may reduce future costs.For example, a crew might build
a work platform rather than purchase, replace, and maintain fall arrest
equipment. "Enclosure and isolation" creates a physical barrier
between personnel and hazards, such as using remotely controlled equipment.
Fume hoods can remove airborne contaminants as a means of engineered control.
ADMINISTRATIVE CONTROLS ACTION
Administrative
controls are changes to the way people work. Examples of administrative
controls include procedure changes, employee training, and installation of
signs and warning labels (such as those in the Workplace Hazardous Materials
Information System). Administrative controls do not remove hazards, but limit
or prevent people's exposure to the hazards, such as completing road
construction at night when fewer people are driving.
PERSONAL
PROTECTIVE EQUIPMENT ACTION
Personal
protective equipment (PPE) includes gloves, Uniform, respirators, hard hats,
safety glasses, high-visibility clothing, and safety footwear. PPE is the least
effective means of controlling hazards because of the high potential for damage
to render PPE ineffective. Additionally, some PPE, such as respirators,
increase physiological effort to complete a task and, therefore, may require
medical examinations to ensure workers can use the PPE without risking their
health.
WHAT WILL HAPPEN
IF RISK NOT CONTROL
Risks
may cause suffering to people, losses for companies and damage to our economy,
and, as such, they should be avoided or – where this is not possible – reduced
to a minimum. Common sense and legislation dictate that employers assess the
risks for their staff and implement related preventive or control measures.
Preventive measures aim at avoiding risks whereas control measures are put in
place in order to reduce and manage risks. To combat the vast number of very
different risks, for example slipping, falling, developing musculoskeletal
disorders (MSD), radiation, stress, etc., researchers, technicians and
practitioners have developed an even higher number of preventive and control
measures. This means that employers need guidance in order to choose the most
efficient measure. To facilitate this, measures are classified, e.g. as
elimination measures, technical measures, organisational measures or personal
measures, and these types are put into a hierarchical order. The highest level
is seen as the most efficient one in terms of combating the risks. The lower
levels are only to be applied, if no higher level measures are available, or if
the application would be disproportionate in terms of effort and achievable
result. In most cases, a package of measures should be applied, whereby the
individual measures could be attributed to different hierarchical levels.
CONCLUSION
In my conclusion, we must to take note about personal protective equipment because it really important when employee start working. Next, it also can reduce injury and protect the employee from the hazard while working. Lastly, personal protective equipment is our responsibility to wear it because it can protect the employee from high risk danger.
