HOW ENSURE SAFE SITE LIGHTING AT WORKPLACE

Why Good Lighting Need to Ensure:

Lighting at work is very important for the health and safety of everyone in the workplace.

Good lighting plays an important role in safeguarding health at work by enabling employees to perform their work comfortably and efficiently.

It also allows employees to read clearly labels and safety instructions, such as those affixed to hazardous substances to ensure compliance with safety measures for the prevention of hazards.

Accordingly, there should be an appropriate level of the light falling on the surface on which employees are working. Excessive contrast, strong glare and light flickering in their fields of vision are also inappropriate.

Sponsored:

To ensure good lighting, the person responsible for a workplace should arrange for a suitable assessment on the lighting levels in the workplace.

To be ensure at workplace the quicker and easier to see a hazard the higher the likelihood of avoiding it.

The types of dangers present at work therefore determines the lighting requirements for safe operation.

Ensuring the correct level of lighting is particularly important when working at night.

Tips to Keep Safe Temporary Lighting in workplace:

Temporary lighting wiring cable is not used for more than one year on a construction site;

Temporary lighting wiring cable is removed immediately when work is complete;

Ensure the conductors and equipment is protected from over current by circuit breakers, fuses, etc., and can safely carry the load;

Grounding is ensured through either a ground fault circuit interrupter system or assured equipment grounding conductor program;

Lamps are located at standard vertical and horizontal distances from the work area;

Workers exposed to possible electric shock are provided and use suitable protective equipment or devices.

If there is TEMPORARY lighting in your workplace, check following to ensure:

HAZARD NOISE AT WORKPLACE KILLING HEARING POWER

Who Damaging our Hearing Power?

If people are having difficulty hearing what others say, or have to shout to be understood at a distance of one meter, noise levels are likely to be damaging our hearing power.

The louder the noise in near the human, the more damage it can cause for them. Industrial noise and vibration can cause long-term damage to employee senses. Hearing and touch can be severely affected by exposure to excess levels of noise and vibration.

Impact of Noise Pollution:

Excessive noise causes the permanent damage to hearing. Neither surgery nor a hearing aid can help correct this type of hearing loss. Short term exposure to loud noise can also cause a temporary change in hearing. Industrial noises or sound pollution can cause hearing loss either progressively or impact of long period of time. Hearing damage can be caused immediately by exposure to peak sound waves produced by explosive high level of sounds. Anyone can be exposed to excessive noise level that working in noisy environments such as factories, foundries, working with power tools, plant and machinery, airports and construction sites are among those most at risk.

Identifying noise hazards:

It’s not necessarily a specialist skills or equipment to make a preliminary assessment to identify sources of hazardous noise. However it should be done in consultation with those who understand the working processes on such affected workers and their health and safety representatives. Regular walk-through inspection with relevant workers and health and safety representatives will make a good start towards hazardous noise identification.

Awareness and Training:

Employees need to have the knowledge necessary to do all they can, and for you to do all you can, to reduce the risk of an injury occurring in your workplace. If an employee is not aware of the risks they are exposed to and how to minimize those risks, they will not be compelled to do what they can to protect themselves.

Employees need to train up about hazards they are exposed to in their jobs and when carrying out certain tasks. They need to knowledge how to use personal protective equipment (PPE) in an effort to reduce the risks in workplace.

Today it’s very easy to come in touch on many occupational health and safety issues that are included in more detail in the OH&S Handbook. So, just need to take initiative and follow up to the training and awareness about hazardous noise on workplace.

When dealing with NOISE, check:

Have you had information and training so you know what are the risks from noise on site, and what to do to avoid these risks?

People who are not involved in the work kept away from the source of the noise?

Is suitable hearing protection provided and worn in noisy areas?

Have hearing protection zones been marked with the type of hearing protectors required?
