We take safety at work very seriously. Safety seminars and safety workshops are conducted regularly at Sub-divisions making sure that the workers observe all safety precautions.
At PESCO, safety of its employees is top priority in the business plan. We treat Safety as a core business value. PESCO is striving upon to become a regional and national leader in Safety and for this to happen all management must ensure that this is part of their business plans. PESCO is now headed towards its vision of Compliance which is creating an accident free atmosphere in the company.Safety Guide for General Public
The voltage of the electricity and the available electrical current has enough power to cause death by electrocution. Even changing a light bulb without unplugging the lamp can be hazardous because coming in contact with the live part of the socket could kill a person.
All electrical systems have the potential to cause harm. Electricity can be either "static" or "dynamic." Dynamic electricity is the uniform motion of electrons through a conductor (this is also called Electric Current). Conductors are materials that allow the movement of electricity through it. Most metals are conductors. The human body is also a conductor.
Static electricity is accumulation of charge on surfaces as a result of contact and friction with another surface. This contact/friction causes an accumulation of electrons on one surface, and a deficiency of electrons on the other surface.
Electric current cannot exist without a path to and from the conductor. Electricity will form a "path" or "loop". When you plug in a device (e.g., a power tool), the electricity takes the easiest path from the plug-in, to the tool, and back to the power source. This is also known as creating or completing an electrical circuit.
People are injured when they become part of the electrical circuit. Humans are more conductive than the earth (the ground we stand on) which means if there is no other easy path, electricity will try to flow through our bodies.
There are four main types of injuries: electrocution (fatal), electric shock, burns, and falls. These injuries can happen in various ways:
Do not work close to power lines. Check with PESCO when working, driving, parking, or storing materials closer than 15 m (49 feet) to overhead power lines.
If you must be close to power lines, you must first call PESCO and we will assist you.
If your vehicle comes into contact with a power line:
Inspect portable cord-and-plug connected equipment, extension cords, power bars, and electrical fittings for damage or wear before each use. Repair or replace damaged equipment immediately.
Always tape extension cords to walls or floors when necessary. Nails and staples can damage extension cords causing fire and shock hazards.
Use extension cords or equipment that is rated for the level of amperage or wattage that you are using.
Be aware that unusually warm or hot outlets may be a sign that unsafe wiring conditions exists. Unplug any cords or extension cords to these outlets and do not use until a qualified electrician has checked the wiring.
Always use ladders made with non-conductive side rails (e.g., fibreglass) when working with or near electricity or power lines.
Place halogen lights away from combustible materials such as cloths or curtains. Halogen lamps can become very hot and may be a fire hazard.
Risk of electric shock is greater in areas that are wet or damp. Install Ground Fault Circuit Interrupters (also known as Circuit-breakers) as they will interrupt the electrical circuit before a current sufficient to cause death or serious injury occurs.
Use a portable in-line Circuit-breaker if you are not certain that the receptacle you are plugging your extension cord into is Circuit-breaker protected.
Make sure that exposed receptacle boxes are made of non-conductive materials.
Know where the panel and circuit breakers are located in case of an emergency.
Label all circuit breakers and fuse boxes clearly. Each switch should be positively identified as to which outlet or appliance it is for.
Do not use outlets or cords that have exposed wiring.
Do not use portable cord-and-plug connected power tools with the guards removed.
Do not block access to panels and circuit breakers or fuse boxes.
Do not touch a person or electrical apparatus in the event of an electrical accident. Always disconnect the power source first.
Switch all tools OFF before connecting them to a power supply.
Disconnect and lockout the power supply before completing any maintenance work tasks or making adjustments.
Ensure tools are properly grounded or double-insulated. The grounded equipment must have an approved 3-wire cord with a 3-prong plug. This plug should be plugged in a properly grounded 3-pole outlet.
Test all tools for effective grounding with a continuity tester or a Circuit-breaker before use.
Do not bypass the on/off switch and operate the tools by connecting and disconnecting the power cord.
Do not use electrical equipment in wet conditions or damp locations unless the equipment is connected to a Circuit-breaker.
Do not clean tools with flammable or toxic solvents.
Do not operate tools in an area containing explosive vapours or gases, unless they are intrinsically safe and only if you follow the manufacturer's guidelines.
Keep power cords clear of tools during use.
Suspend extension cords temporarily during use over aisles or work areas to eliminate stumbling or tripping hazards.
Replace open front plugs with dead front plugs. Dead front plugs are sealed and present less danger of shock or short circuit.
Do not use light duty extension cords in a non-residential situation.
Do not carry or lift up electrical equipment by the power cord.
Do not tie cords in tight knots. Knots can cause short circuits and shocks. Loop the cords or use a twist lock plug.
A Circuit-breaker works by detecting any loss of electrical current in a circuit (e.g., it will trip at a maximum of 6mA). When a loss is detected, the Circuit-breaker turns the electricity off before severe injuries or electrocution can occur. A painful non-fatal shock may occur during the time that it takes for the Circuit-breaker to cut off the electricity so it is important to use the Circuit-breaker as an extra protective measure rather than a replacement for safe work practices.
Circuit-breaker wall outlets can be installed in place of standard outlets to protect against electrocution for just that outlet, or a series of outlets in the same branch circuit. A Circuit Breaker can be installed on some circuit breaker electrical panels to protect an entire branch circuit.
It is important that you follow the manufacturer's instructions with respect to the use of a Circuit-breaker. Test permanently wired Circuit-breaker monthly, and portable devices before each use.
