CONTROL Control is the 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. Based on the observation from the risk analysis, there are some processes to prevent the identified hazards. These processes can be referred to the hierarchy of control. The hierarchy of control can be divided into six types which are: a. Elimination – Getting rid of a hazardous job, tool, process, machine or substance is perhaps the best way of protecting workers. For example, the workers should stop loading the pipes by their own and use mechanical lifter instead to prevent muscular strain or back pain.

b. Substitution – Sometimes doing the same work in a less hazardous way is possible. For example, a hazardous chemical can be replaced with a less hazardous one. Controls must protect workers from any new hazards that are created.

c. Engineering control - Redesign of equipment, work process or work environment through modification to isolate or enclose the hazards. For instance, modifying exhaust system to reduce noise.

d. Isolation - Isolating or also known as separating the hazard from the person, or the person from the hazard. If a hazard cannot be eliminated or replaced, it can sometimes be isolated, contained or otherwise kept it away from workers. For an example, placing guards on moving parts of machinery, placing barriers around a spill until cleaned up and also using remote-controlled handling equipment for hazardous processes.

e. Administration control – It is a reduction of exposure to risk through use of procedures or instruction. For instance, workers can be rotated through jobs requiring repetitive tendon and muscle movements to prevent cumulative trauma injuries. Noisy processes can be scheduled when no one is in the workplace. f. Personal protective equipment - Personal protective equipment (PPE) and clothing is used

when other controls measures

are not feasible and where additional protection is needed. Workers must be trained to use and maintain equipment properly. The employer and workers must understand the limitations of the personal protective equipment. The employer is expected to require workers to use their equipment whenever it is needed. Care must be taken to ensure that equipment is working properly. Otherwise, PPE may endanger a workers health by providing an illusion of protection.
