INTRODUCTION

Electricity is essential to modern life,both at home and on the job.Some employeesengineers,electricians,electronic technicians and power line workers work with it directly.

THE DEFECTIVE INSULANT HAZARD

IMPROPER GROUNDING HAZARD

When an electrical system is not grounded properly,a hazard exists.Eletrical grounding is used to help prevent people from accidentally coming in contact with eletrical hazard.Grounding is also used to protect that person.By connecting a green ground wire from the metal frame of the refrigerator,if the chassis inadvertently becomes charged for any reason,the unwanted electricity will travel through the wire back to your eletrical panel and tripping the circuit-breaker stopping the flow of electricity.

OVERLOAD HAZARD

Overloads in an electrical system are hazardous because they can produce heat or arcing. Wires and other components in an electrical system or circuit have a maximum amount of current they can carry safely. If too many devices are plugged into a circuit, the electrical current will heat the wires to a very high temperature. If any one tool uses too much current, the wires will heat up.

WET CONDITION HAZARD

Working in wet conditions is hazardous because you may become an easy path for electrical current. If you touch a live wire or other electrical component—and you are well-grounded because you are standing in even a small puddle of water—you will receive a shock.

PREVENTIVE MEASURES IN ELETRICAL SAFETY

Exposed-conductive-parts used in the manufacturing process of an electrical equipment is separated from the live parts of the equipment by the “basic insulation”. Failure of the basic insulation will result in the exposed-conductive-parts being alive.

PROTECTION FROM DIRECT CONTACT

PROTECTION FROM INDIRECT  CONTACT

TO CREATE A SAFE WORKING ENVIROMENT

We can create a safe working enviroment by using proper safety gears,regularly maintain premises,keeping employees happy and company running smoothly

LOCK OUT AND TAG OUT CIRCUIT AND EQUIPMENT

Disconnecting or making safe the equipment involves the removal of all energy sources and is known as isolation. The steps necessary to isolate equipment are often documented in an isolation procedure or a lockout tagout procedure.

OVERLOAD WIRING BY USING THE RIGHT SIZE AND TYPE OF WIRE

Different types of wires with theirs electrical current rating.

INSULATION

Insulator (electricity), the use of material to resist the electric current and magnetism.Insulator such as glass,mica,rubber or plastic used to coat metals and other conductors help stop or reduce the flow of electrical current.

PREVENTIVE

A willing, positive attitude towards safety will help make a safer work environment.

SAFE WORKING ENVIRONMENT

Safe working environments is where risks to their health and safety are properly controlled. Under health and safety law, the primary responsibility for this is down to employers. Employers have a duty to consult with their employees, or their representatives, on health and safety matters.

WHAT WILL HAPPEN IF RISK NOT CONTROL ?

Risk assessments are very important as they form an integral part of an occupational health and safety management plan. They help to:

• Create awareness of hazards and risk.
• Identify who may be at risk (e.g., employees, cleaners, visitors, contractors, the public, etc.).
• Determine whether a control program is required for a particular hazard.
• Determine if existing control measures are adequate or if more should be done.
• Prevent injuries or illnesses, especially when done at the design or planning stage.
• Prioritize hazards and control measures.
• Meet legal requirements where applicable.

CONCLUSION

In order to reduce the hazard or most critical hazard rate, the employer should show commitment towards safety and health practices and therefore give full priority to promote and enforce the safety and health rules in workplace.Hierarchy of control where use in order to minimize and control the most critical hazard and that exist at the workplace. To ensure the safety culture can be implemented in an organization. The management and workers have to take part in any safety and health program and give a full cooperation when comes to safety issues.
