WHY NEED RISK CONTROL
Risk control is, elimination or inactivation of a hazard in a manner such that the hazard does not pose a risk to workers who have to enter into an area or work on equipment in the course of scheduled work. Why do we need risk control?
*Project problems can be reduced as much as 90% by using risk analysis.
*Positives:
1)More info available during planning.
2)Improved probability of success/optimum project.
*Negatives:
1)Belief that all risks are accounted for.
2)Project cut due risk level.
TYPES OF CONTROL
Substitution
·
Substitution is the most effective way to control hazards
· Involves removing something that produces hazards (similar to elimination), and replacing with something has does not produce a hazard.
· To be effective control, the new product must not produce another hazard.
Elimination
What do we mean by ELIMINATION?
· Elimination of the hazard is the most effective means of hazard control. It involves the physical removal of the hazard, for example, if employees are required to work high above the ground, the hazard can be eliminate by moving the piece they are working on to “ground level” to eliminate the need to work at heights.
Isolation
·
Use to prevent transmission of microorganisms spread by direct/indirect contact with the source
· Examples:
-MRSA
-VRE
-C. diff
-Contagious skin infections….Lice & Scabies
Engineering Controls
Below are examples of this strategy
· Redesigning a process to use less toxic chemicals
· Redesigning a work station to relieve physical stress and remove ergonomic hazards
· Designing general ventilation with sufficient fresh outdoor air to improve indoor air quality and to provide a safe, healthful atmosphere
ENGINEERING AND ADMINISTRATIVE CONTROLS
§ Engneering controls are steps taken, other than administrative or personal protection procedures, to reduce the sound level at the source or within the hearing zone of workers. All of these controls are designed to reduce noise at the source , along its path, r at the receiver.
§ Administrative Controls are controls that reduce the exposure of the employees to noise rather than reducing the noise. Administrative controls should be considered a second level approach with engineering controls given top priority.
Administrative controls
§ Unlike engineering controls, which keep hazardous noise from reaching a worker administrative controls change worker’ activities to lower their exposure.
§ Closely related to administrative controls are work-practice controls, which emphasize safe practises.
§ Administrative and work-practise controls are usually less expensive than engineering controls because there is no cost in changing or modifying equipment.
§ However, administrative and work-pratice usually aren’t as effective as engineering controls because they don’t control the noise
§ Noisy machines are noisy and the exposure is still present.
WHY IS PPE IMPORTANT?
PPE is design to protect the worker’s body from hazards and injuries such as blunt impacts, electrical hazards, heat, chemicals, and infection.
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.
