Electrical Safety Audit

Electricity is a familiar and necessary part of everyday life, but electricity can kill or severely injure people and cause damage to property. Some employees -- engineers, electricians, electronic technicians, and power line workers, among them -- work with electricity directly. Long recognized as a serious workplace hazard, electricity often puts employees face-to-face with phenomena like electric shock, electrocution, burns, fires, and explosions accounting for a sizable share of on-the-job fatalities. Research shows that over hundred people die each year because of electrical accidents on machines that are being repaired, set up, or serviced have not been properly locked out, earthed or protections not operated in time. An Energy Safety Audit helps avoid these fatalities.

Techlabs engineering experts are there for your needs of safety assessment. Our engineers have thorough experience of assessment of your electrical network installations, various operating procedures as per National standards. With through knowledge of various standards like IEEE 1584, NFPA 70, IEEE 80, IEEE 81 etc, TECHLABS engineers recommend & implement the safety solutions. There are simple precautions when working with or near electricity that can be taken to significantly reduce the risk of electrical injury to you and others around you.

OBJECTIVES:

• Electrical hazards identification and their assessment
• Implementing preventive measures for the same.
• Review of electrical preventive maintenance ongoing programs
• Compliance to the statutory requirement.
• Examining safety procedures in maintenance and operation.
• Scrutinizing the program to eliminate electrical fires.

SCOPE OF THE AUDIT:

• Physical inspection of the plant
• Review of protection devices and adequacy of Cable, Motors and Drives with respect to current measurements
• Review of electrical preventive maintenance ongoing programs
• Checking earthing system.
• Examination of plant lightning protection system as per recommended standards.
• Transformer oil , IR and Earth resistance tests
• Review of past electrical accidents and RCA.
• Electrical Audit safety report along with Recommendation.

SPECIALISED SERVICES:

Techlabs provide complete solutions in following areas which aids your engineers to enhance safety of electrical installations in your plants/industries:

• ARC Flash Hazards Assessment

Electrical short circuits and faults are extremely dangerous and are potentially fatal to personnel. Arc flash occurs when phase conductors are shorted and ionization of the air occurs. Arc Flash Hazard Studies are performed to determine the risk to personnel, warn them of the hazards, and to instruct them as to what kind of personal protective equipment that they must wear.



The services offered by Techlabs include



a) Collection of technical data from site/plant/industry & prepare network model in an industry-standard computer-modelling and simulation software



b) Short-circuit studies & equipment evaluations based on magnitude of short-circuit current followed by recommendatory reports



c) Perform ARC Flash calculations at each bus/panel/switchboard in the system & identify the hazards, assess existing protection coordination & recommend suitable PPEs




d) Supply of required PPEs, safety gears, warning labels & positioning warning labels on various Electrical panels/ switchboards



e) Provide detailed training on ARC Flash Hazards program & safety.

• Earthing /Grounding System Assessment & Design:

Earthing system is vital part of any electrical installations. Accurately designed earthing system is very much necessary to ensure safety of working personnel, equipments and correct operation of protective devices during earth faults, lightning strikes, switching surges and occurrence of induced voltages, currents on equipments, conductors, cables or structure etc.



Even though objective of all earthing / grounding system is the same, methodology for design, engineering, installation, commissioning & maintenance of earthing system varies with requirement of electric system depending on its location, layouts, operations etc.



Techlabs engineers with their decade years of experience are at your services for detailed design of earthing system.



We provide following services for Earthing / Grounding System design:



• Survey of site, measurement of soil resistivity data
• Performing soil resistivity analysis & derivations of correct soil model for earthing system design
• Collection of plant/switch yard layout drawings for location, plant/switchyard layout i.e. equipment location etc.
• Detailed design of earthmats/ earthing systems using FEA analysis tools which will comply with all safety criterions based on electrical standards. Risers calculations
• Preparation of earthing layouts, installation drawings & system specifications for earthing
• Estimation of Bill of materials & costing for proposed earthing system
• Services for assessment of existing earthing system includes study of design, provide necessary recommendations, drawings & reports, supply & installation of necessary earthing material i.e. earth pits, strips etc.
• Basic & Detailed Engineering Services
