NOISE A SILENT DESTRUCTIVE HAZARD.                                                                                             Hello there, this is Goke Akingbade (your safety guide) bringing you another topic to delve on.Today we will considering Noise and how harmful it is.

Part of what makes us human and alive is our sense of hearing. The ability to differentiate a particular keynote from another one and sound in general. We are all used to listening to music, radio via our head phones during leisure times or when we are stuck in traffic. Scientifically, it has been proven that the maximum allowable sound level is 80 decibel. This is the level that the human ear can accommodate, any level of sound beyond this has turned to noise.

The ear is divided into the outer, middle and inner ear. The inner ear is linked to haircells. You see the ear drum is similar to a drum beaten by a drummer, it vibrates. When an external signal reaches the ear, the ear drum vibrates, it then moves three tiny bores in the middle ear. This movement transmits the vibration to fluid in the inner ear. The movement of fluid is then picked up by tiny hair cells which transfer the movement to nerves. The nerves then send signals to the brain, where they are recognized as sound. When a person exposes himself to high-decibel for a long period of time, it can later damage the tiny hair cells. As a result of this, fewer signals are thus sent to the brain and then the person will not be able to hear well. This is because the hair cells cannot be replaced or restored, the damage is permanent. Noise is responsible for the death of many hair cells in workers in noisy jobs.

If you are talking to a friend or colleague while you have your head phones on listening to music. If you can’t hear what your friend or colleague is saying and you need to shout before you think you will be heard, then the music is too loud and has become noise to your ears. It is so important that we be mindful of the level of sound that we expose our ears to everyday. The haircells inside the inner ear are very sensitive and so the maximum allowable amount of sound (80 decibel) should not be exceeded.   If you find yourself exposed to noise, it is important that you move away from the area of exposure.

Workers especially in the mining industry, construction industry are more prone to noise which can have a negative impact on their hearing. Till I come your way again, this is Goke (your Safety guide) signing off.




Hello there, this is Goke Akingbade(your Safety Guide). Sorry I have been out of touch for a month, but It is great to be back. We will be looking at the role of a Safety Supervisor.

The main goal of safety education is to shape attitudes. Attitudes in turn shape behaviours. It is important for a safety supervisor to formally instruct and train workers, so as to improve the employee’s ability to work safely.

Safety instruction emphasizes what is known as “natural and system consequences” of personal behaviours and actions of workers. This is the act of connecting safety training with accountability

(I)  NATURAL CONSEQUENCES : These explain how workers will physically or incur injuries if they fail to comply with safety rules and regulations. ”if you don’t use the safety belt, you will be killed if you fall”

(II) SYSTEM CONSEQUENCES: These explain how employee behaviours will result in discipline and recognition for their behavior. ”if you fail to use the safety belt, you will be sacked, if you consistently use the safety belt, you will be recognized and rewarded”.

Safety training on the other hand, tells the learner “how” to work safely. It provides the worker the knowledge and through practice, the skills needed to engage in safe work procedures. As a supervisor trains, he gains more insight and expertise on the procedure he is training on.This thus makes him better qualified to supervise for safety and more confidently manage accountability of the workers.

WHEN TO TRAIN                                                                                                                                                                 (A) Initial safety orientation is more important, it should hold when a new worker is recruited, and more specific training must occur before the worker starts any job task that exposes him or her to any form of hazard.

REASONS WHY NEW EMPLOYEES NEED INITIAL SAFETY ORIENTATION                                                                      

The two primary reasons are associated with the concepts of common sense and corporate culture.    (1) According the Webster’s dictionary, common sense is the “ability to make sound judgments”.     We develop our “sense” of things in our environment, majorly through formal education, observation and personal experience. And these cannot be the same for everyone.                                                                                                                                              (2)   A supervisor must never assume that the corporate culture (standards and expectations) of a new worker’s previous employer is similar his own.If you ask a new worker if they know safe work practices, for a given task, they may reply positively, but the response is based on the previous company’s procedure which may be different from the procedure that is required by your organization. This implies that every new worker needs to know why and how to accomplish a job task according to the way of the supervisor from the onset of work.

Initial Safety Orientation in some circles, it is called  Induction.

In conclusion, it is crucial for the safety supervisor to pass across the message that every worker is responsible and accountable in maintaining a safe workplace.
