The plant you are working in as a safety engineer has five u

The plant you are working in as a safety engineer has five units than involve safety hazards, as follows: Mechanical operations producing high noise levels that necessitate the use of hearing protection device. Power press (half revolution type, hands out) for drilling metal product, necessitating the use of machine guard Forklift usage in a hazardous location where ether (highly flammable material) is stored in tight containers. A suitable forklift type must be used. Maintenance workshop where electric and metal cast grinding, both requiring face and eye protection Confined space area with potentially high concentration of hazardous gas, necessitating the use of respiratory Protection fix a worker who enters the area for an average of one hour on a daily basis. The top management asked you to design a program for controlling the five hazards using the above- mentioned safety measures. Show the design strategy for each of the five safety programs emphasizing the following Define the consequences (adverse effect) of each of the hazards. Mention the alternative solutions for ach hazard showing the advantages and disadvantages, if any Show how to decide the optimum solution among mentioned each hazard. Propose measureable indicators that tell you whether the solution is effective or not after being applied.

Solution

consequences of hazzards and solutions:

1) mechanical operations producing noise affects the concentration level of the employees.It is also responsible for the increase in stress and may result in hearing impairement,ischemic heart problem etc.

so to avoid this we may shield the highly noisy machines and zones with sound barriers or provide the personels with devices like ear plugs.

2) power press for drilling metal in continuous operation disperses the cut metal chips and particles alongside so can cause harm to worker nearby directly or indirectly.

here to avoid any danger we can incorporate automatic press operation by connecting press with a micro computer like cnc machine operation.

3) in the handling of highly flammable material if the fuel operated forklift is used , due to high heat generation it may cause fire which will take a toll of many things.so its advised to use a battery operated forklift in the area.

the usage of automated storage system can be used which can avoid the contact of material with both humans and any other fuel

4) for electric welding its always recommended to use rubber hand gloves to avoid the shock from high voltage power souce which is used for welding and as we know during arc formation it gives rise to various hazardous radiations which can harm our sightings so eye protectiom goggles should be used

5) in confined space area where there is hazardous gas precipatation ,it produces high risk for workers health that is if inhaled or comes in contact with either skin or eyes may result in dangerous effects like irritation of eyes, headache, nausia,lungs problem etc.

Monitoring and evaluation of any program is vital to determine whether it works or not so to find the optimal solutions for the problem we use the various optimization methods like weighted score method.

in weighted residual method some weights or frequencies are assigned to the factors on which problem is based,like for first case for reducing sound if we are implementing the sheilds then its important to note that the effectiveness of workers improved per unit cost spent

In these types of situations, using a weighted average can be much quicker and easier than the traditional method of adding up each individual value and dividing by the total. This is especially useful when you are dealing with large data sets that may contain hundreds or even thousands of items but only a finite number of choices.

so here the relation between cost spent and production and effectiveness of workers are the factors on which weights should be applied

the weights applied should be such that average production is maximum

similarly for power press the cost of implementing automation should be justified by the efficency and rate of cutting material.

in case of worklift the facrors consider should be safety only which must be given prime importance
