 As pe site incharge shri SKB Vali sir  must ensure safety all time 

Operation of a new utility-scale solar plant, such as the Trinity project, involves significant hazards related to high-voltage electricity, environmental conditions, and mechanical systems. The primary risks during the operational phase include electrical shocks, fire hazards, and environmental factors like extreme weather. 

Here is a list of operational hazards for a new solar plant:

1. Electrical Hazards 

High-Voltage Shock/Electrocution: Exposure to energized conductors, particularly in combiner boxes and inverters (up to 1,500 V DC), poses a lethal risk.

Arc Flash/Arc Faults: High-power discharges between conductors can cause fires or explosions, especially when checking energized equipment.

Persistent Energy Production: PV arrays generate electricity whenever exposed to light, making it difficult to fully isolate the system for maintenance.

Faulty Grounding: Improperly grounded components can lead to electrifying the support structures. 

2. Fire and Explosion Hazards

Electrical Fires: Caused by arcing, short circuits, or loose connections in inverters, combiner boxes, and cabling.

Battery Energy Storage Systems (BESS): If included, these pose fire and thermal runaway risks.

Toxic Fumes: Burning solar components and materials can release hazardous smoke.

Grass/Brush Fires: Dry vegetation under panels increases fire risks. 

3. Site and Environmental Hazards

Lightning Strikes: The large, metallic, elevated surface area of the solar array makes the site more prone to lightning during storms.

Slips, Trips, and Falls: Uneven terrain, mud, and cables pose risks, especially in winter or wet conditions.

Weather-Related Illnesses: Exposure to high heat, causing dehydration, sunstroke, or heat exhaustion, is a major concern.

Wildlife and Livestock: Potential for venomous snake bites, spider bites, or insect stings. 

4. Mechanical and Maintenance Hazards

Moving Machinery: Risk of collision with maintenance vehicles, trackers, or automated equipment.

Mechanical Injuries: Hand tools, power tools, and unsecured equipment can cause injuries.

Falling Panels/Debris: Improperly secured panels or structural failure, particularly in windy conditions. 

5. Chemical Hazards

Cleaning Agents: Chemicals or detergents used to clean panels can contaminate the ground, necessitating proper containment.

Hazardous Materials: Older or damaged panels may leak toxic materials like cadmium or lead, though this is less common with new panels. 

6. Operational/Human Factors

Complacency: O&M technicians becoming too comfortable and overlooking dangers in an operating plant.

Ineffective Lockout/Tagout: Failure to properly isolate equipment before performing maintenance. 

Key Mitigation Strategies

Rapid Shutdown Systems: Required to reduce voltage within 30 seconds.

PPE & Tools: Use of CAT III/IV rated multimeters and arc-rated clothing.

Training & Safety Protocols: Regular training, adherence to O&M procedures, and, if applicable, using drones for inspection to reduce human exposure. 

For a 33kV line, minimum safe distances vary, but generally, expect at least 5.2 meters (around 17 feet) vertical clearance from the ground and a significant horizontal buffer for construction, often around 2.2 meters (7 feet) from poles, with larger distances (6-9 meters/20-30 feet) required for working near towers or with heavy machinery, and 10 feet (3 meters) is a common general safety practice for personnel. Always maintain a much larger distance for downed lines (35+ ft) and contact the utility company. 

Minimum Clearances (Varies by Region/Rule) 

Vertical (Ground): Around 5.2 meters (17 ft) for the lowest conductor, increasing with height or across streets (e.g., 6.1m/20ft).

Horizontal (Construction/Excavation):

Near Poles: ~2.2 meters (7 ft) for 11-33kV lines.

Near Towers: ~6 meters (20 ft) for 11-33kV lines.

For heavy machinery, larger setbacks (e.g., 9 meters/30 ft) are often mandated.

General Personnel: A common safety guideline suggests 10 feet (about 3 meters) as a minimum buffer. 

Key Safety Considerations

Downed Lines: Stay far away (at least 35 feet/10.7m) and call emergency services/utility company immediately due to dangerous ground currents (step potential).

Sagging: Lines sag, so clearance is reduced in the middle of spans, requiring extra caution.

Regulations: Local electrical safety standards (like India's Indian Electricity Rules) dictate specific clearances, so check local rules.

Title: Selection, Installation and Maintenance of First-Aid Fire Extinguishers - Portable and Mobile Code of Practice (Fifth Revision) Bureau of Indian Standards

This standard is a Code of Practice that provides detailed guidelines on how to properly choose, install, and maintain portable and mobile (wheeled) fire extinguishers used for initial firefighting in buildings and facilities in India. Bureau of Indian Standards

It replaces the older version (IS 2190:2010) and reflects updated practices and requirements in fire extinguisher safety and management. Bureau of Indian Standards

Main Purposes of IS 2190:2024

1. Selection of Fire Extinguishers

The standard defines how to select the right type and size of extinguisher based on:

Type of fire hazard (like solids, liquids, gases)

Occupancy and hazard level (light, moderate, high)

Fire classes (A, B, C, D, F)

It ensures that extinguishers are suitable for the specific kinds of fire risks present. Safety Lake

2. Installation Requirements

It specifies how extinguishers should be: Mounted (height above the floor) Placed (visibility, easy access, along escape routes) Proper placement helps people reach them quickly in emergencies. Safety Lake

Positioned relative to hazard areas

3. Maintenance & Inspection

The standard details ongoing responsibilities to ensure extinguishers remain functional, including:

Regular visual checks

Scheduled maintenance

Safety signages are a simple but critical control for preventing accidents and communicating hazards

 Proper Use of Safety Signages

 

Safety signages are a simple but critical control for preventing accidents and communicating hazards. When used correctly, they reinforce safe behavior, guide decision-making, and support compliance with HSE requirements on site.

1. Purpose of Safety Signages

Warn people about hazards that may not be obvious

Provide clear instructions and mandatory actions

Prohibit unsafe behaviors

Identify emergency equipment, exits, and first aid facilities

Support safe traffic and pedestrian movement

Signage should always support, not replace, other controls such as engineering measures, training, and supervision.

2. Types of Safety Signages

Warning signs (Yellow): Indicate potential hazards, for example, moving vehicles or overhead loads

Mandatory signs (Blue): Specify required actions, such as wearing PPE

Prohibition signs (Red circle with diagonal): Forbid dangerous actions, such as smoking or unauthorized entry

Emergency signs (Green): Show escape routes, assembly points, and first aid locations

Fire signs (Red): Identify fire alarms, extinguishers, and hose reels

3. Proper Placement

Position signs at eye level and in well-lit areas

Place signs before the hazard, not after it

Ensure visibility is not blocked by equipment, materials, or poor housekeeping

Use additional signs where risks change due to work activities

4. Good Practice for Use

Use standard, recognized symbols and colors

Keep messages short, clear, and easy to understand

Ensure signs are suitable for the environment, weather-resistant and durable

Replace damaged, faded, or outdated signs immediately

Avoid sign overload; too many signs reduce impact and compliance

5. Training and Monitoring

Train workers and visitors on the meaning of all site signages

Include signage awareness in inductions and toolbox talks

Regularly inspect signage during HSE inspections

Act on repeated non-compliance; signage alone is not enough

6. Key Reminder

Safety signages are most effective when it is visible, understood, and respected. Poorly placed or ignored signs are a warning sign of a weak safety culture and must be addressed promptly.

Residual_Risk

 Residual_Risk :-

is the amount of risk that remains after all feasible risk reduction measures (controls) have been implemented, acknowledging that some risk is unavoidable. 

It's the leftover exposure after addressing inherent risks, representing what's left after you've done your best to mitigate threats, like the slight chance a child could still access medication despite child-proof caps. 

Managing residual risk involves setting acceptable tolerance levels and continuously monitoring it, as the goal of risk management is to reduce it to an acceptable or tolerable level, not eliminate it entirely. 

Key Concepts :-

- Inherent Risk: 

The initial level of risk before any controls are applied.

Controls: Actions, policies, or systems put in place to reduce risk (e.g., safety caps, security protocols, training).

Residual Risk: The risk that persists after controls are applied. 

Examples :-

Cybersecurity: 

Even with strong firewalls, a clever phishing attack might still succeed, leaving a residual risk.

Health & Safety: 

Wearing seatbelts reduces accident risk, but the risk of injury in a crash isn't zero, so residual risk remains.

Project Management: 

A project might have controls for budget overruns, but unexpected delays (residual risk) can still occur. 

Formula :-

A simple way to think about it is:

Residual Risk = Inherent Risk - Impact of Risk Controls. 

Management Organizations aim to reduce residual risk to a level within their risk appetite (what they're willing to accept) by applying measures like safety nets, emergency plans, or risk transfer (insurance).

During this first-time acceptance, key EHSQ monitoring areas include Safety, Environmental, Quality Assurance, Technical Compliance, and Documentation checks.

 Environmental, Health, Safety, and Quality (EHSQ) monitoring at the field level during the first-time acceptance of a solar plant ensures that the project is compliant with regulations, safe for operation, and meets performance guarantees. This crucial phase—often involving Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) or Commissioning—requires a systematic checklist to verify all components. 

During this first-time acceptance, key EHSQ monitoring areas include Safety, Environmental, Quality Assurance, Technical Compliance, and Documentation checks. 

Key EHSQ Monitoring Areas

Safety Monitoring (HSE): This involves verifying compliance with the Permit to Work (PTW) system, Lockout/Tagout (LOTO) procedures during component trials, and proper use of Personal Protective Equipment (PPE). Functional testing of emergency systems and structural safety inspections are also crucial.

Environmental Monitoring: Focuses on proper waste management, including the disposal of construction debris and packaging materials, and ensuring site restoration after installation.

Quality Assurance & Technical Compliance (Q): This includes visual inspections of components like modules, inverters, and cables for any damage. Electrical testing is conducted on both DC and AC sides, including insulation resistance and voltage tests. Earthing resistance is tested, and random torque testing of fasteners is performed. Functional testing verifies inverter start-up, grid synchronization, and AC output.

Documentation Check: This involves verifying as-built drawings match the installed configuration and reviewing manufacturer test certificates for key components. Compliance reports, such as safety clearances and net-metering approvals, are also checked. 

First-Time Acceptance Procedure

The procedure typically involves a visual inspection of the site, followed by cold commissioning (before power) to perform insulation and earthing tests. Hot commissioning (after power) includes energizing the system and verifying voltage, current, and grid synchronization. A performance check verifies the inverter's output and ensures all components are functioning before final sign-off. 

Quality monitoring during the first-time acceptance of a solar power plant is a critical process,

 Quality monitoring during the first-time acceptance of a solar power plant is a critical process, often referred to as commissioning or pre-commissioning inspection, to ensure the system is built according to design and will operate safely over its lifetime. This process typically involves a mix of visual inspections, electrical tests, and performance validation. 

Here is a list of quality monitoring checks for first-time solar plant acceptance:

 1. Mechanical & Visual Inspection Module Inspection: Check for breakage, chips, cracks, delamination, or manufacturing defects.Mounting Structure: Verify structural integrity, alignment, tightness of bolts/nuts, and proper corrosion protection.Shading Analysis: Confirm no shading from trees, buildings, or other panels.Cable Management: Ensure DC cables are properly dressed, supported, protected from damage, and that bend radius limits are followed.Labeling Compliance: Verify safety warnings, component identification, and circuit labeling (e.g., string numbers). 

2. Electrical System Testing Insulation Resistance (Megger Test): Test DC and AC circuits to detect insulation failures (minimum resistance should meet standards, e.g., 20 MΩ for high voltage).Open Circuit Voltage (\(V_{oc}\)) & Short Circuit Current (\(I_{sc}\)): Measure for each string to confirm correct module connection and wiring.Polarity Check: Verify correct polarity of all strings and arrays before connecting to the inverter.Grounding/Earthing: Check continuity of all metallic components and measure ground electrode resistance.Connector Inspection: Ensure MC4 connectors are securely crimped and tight.

 3. Equipment Functional Tests Inverter Commissioning: Verify proper mounting, ventilation, firmware updates, and grid parameter settings.Combiner Box/DCDB: Inspect connections, fuses, and surge protection devices (SPD) for proper rating and installation.AC Side Inspection: Check AC cables, switchgear, transformer, and inverter synchronization with the grid.SCADA System: Verify that all data logging, monitoring sensors (irradiance, temp), and communication paths are functional. 

4. Safety & Performance Validation Thermographic Imaging: Use drones or thermal cameras to identify hotspots in panels, connectors, or electrical cabinets.I-V Curve Tracing: Analyze I-V curves for strings to verify output within $\pm$5% of expected power.Performance Ratio (PR) Test: Calculate the plant's performance ratio over a set period to ensure it meets contractual guarantees.Safety Inspection: Validate rapid shutdown mechanisms and emergency procedures.

 5. Documentation & Handover As-built Drawings: Verify that final drawings match the physical installation.Test Reports: Review all test certificates (Megger, I-V, Earthing).Manuals & Warranties: Ensure all operation and maintenance manuals are provided.Punch List: Finalize the "snag list" of items to be corrected. 

Shri SKBValli Sir enforced to all authorities must comply safety first without fail at all time

 First-time acceptance of a solar plant, often referred to as commissioning or taking over, involves transitioning from construction to operation, which introduces several safety and operational hazards., the key hazards are: 

1. Electrical Hazards (High Risk)

Electrocution/Shock: Solar panels generate electricity whenever light hits them, meaning circuits are energized even if not fully connected. Live DC circuits can pose fatal risks, especially during testing of arrays and cabling.

Arc-Flash/Arc Faults: High voltage DC or AC systems (up to 1,500V) can create arc faults that cause fires or explosive arcs of up to 35,000°F (19,500°C). This is common in energized combiner boxes.

Short Circuits: Caused by damaged, loose, or improperly grounded cables and components.

Step Potential: The risk of electric shock from ground voltage differences during a fault, which can occur across the entire site. 

2. Operational & Physical Hazards

Slips, Trips, and Falls: Uneven terrain, loose cables, and mounting structures create tripping hazards, while working at heights (roof-top or carport) poses serious fall risks.

Mechanical Hazards: Moving parts in trackers, power tools, and closing mechanisms, such as cabinet doors, can cause injuries.

Collisions: Vehicle and machinery movement across large, often quiet, sites. 

3. Environmental and Structural Hazards

Fire: Risk of fire from electrical failure (arcing) or external sources.

Lightning Strikes: Metal structures attract lightning, posing a high risk during electrical storms.

Weather-Related Injuries: Heatstroke, sunstroke, dehydration (from working in, direct sun) or cold/rain-related illnesses.

Site Hazards: Mud, standing water, and difficult terrain affecting safe movement. 

4. Technical and Commissioning Hazards

Inverter Malfunctions: Sudden failures due to manufacturing defects or improper design.

Improper Grounding: Failure to properly bond metallic components can lead to energized structures.

Hidden Damage: Structural damage or wiring faults that were not identified during construction. 

5. Other

Hazardous Materials: Handling components that may contain cadmium telluride or other toxic substances.

Animal/Insect Hazards: Wildlife or insects (e.g., snakes, spiders) in remote or rural locations. 

Key Mitigation Measures:

Lockout/Tagout (LOTO): Ensuring circuits are not energized during testing.

Personal Protective Equipment (PPE): Using arc-rated clothing, insulating gloves, and harnesses.

Rapid Shutdown Procedures: Testing that PV modules reduce voltage within required timeframes (e.g., <80V within 30 seconds).

AP’s initiative towards clean and green energy:

CM to lay foundation for environment-friendly green ammonia project in Kakinada tomorrow 

Green ammonia project to be set up with an investment of Rs 13000 cr, offering employment to 2600 youth

 

Amaravati:As part of AP Integrated Clean Energy Policy 2024 initiative Chief Minister N. Chandrababu Naidu is going to lay foundation for a environment-friendly mega green Ammonia plant, the first of its kind in the country in Kakinada tomorrow. The Chief Minister will lay foundation for the project tomorrow at 11.20 a.m and address the gathering. Deputy Chief Minister Pawan Kalyan will also accompany the Chief Minister.

The state Government granted approvals to AM Green of the Greenko Group in January last year to set up a plant with an investment of Rs 13000 crore and annual production capacity of 1.5 MMTA of green ammonia.

Unlike grey and blue ammonia produced using coal, oil, and natural gas, this green ammonia is completely environment-friendly with no carbon emissions. At a time when the world is moving rapidly towards decarbonisation and net-zero emission goals, green hydrogen and green ammonia are emerging as fuels of the future. In this context, the AM Green Ammonia Project in Kakinada is set to become a matter of pride for the entire nation.

The existing grey ammonia plant of Nagarjuna Fertilizers and Chemicals Limited is being redeveloped into a green ammonia plant through a brown field conversion. AM Green is setting up the plant with an investment of Rs 13,000 crore across 495 acres. The project is expected to generate employment opportunities for around 2,600 youth and expected to start production by the end of 2027. 

The AM Green Ammonia Plant is located near Kakinada Port, offering excellent opportunity for exporting ammonia to countries across the globe. AM Green has already signed an agreement with Germany-based Uniper SE to export 125 KTPA of green ammonia annually starting from 2028. The project, being developed with the support of global partners such as Malaysia-based Petronas, Singapore-based GIC, and UAE-based ADIA, is expected to gain significant international recognition.

In addition to this project, AM Green is also setting up a 2-gigawatt electrolyser manufacturing unit in Kakinada at an estimated cost of Rs 2,000 crore.
