Dear Sir,
Very good evening,
Plot 06 -Movable office dated on 06.09.2025
Organized by SGM Sir, in the presence GM Sir, DGM EHSQ- Associates, all plots In charges & Supportive staff.
Goal : Production enhancement, Excel in Operation & Maintenance, EHSQ Improvements.
SGM Sir, welcomed all & asked to all plot in charges to work with dedication , devotion and determination as a leader and empowered them for improvement in all directions in particular plot and also will be appreciated and awarded by authorities based on ground level improvement & performance .
It is today's focused on DAILY ACTIVITIES AND FIMER INVERTER INSTALLATION , COMMISSIONING AND OPERATION AND MAINTENANCE monitoring and daily updating
As per observation issue and solution.
It has been found that since 1 September to 6 September Operation & Maintenance, EHSQ Improvements are continually increasing -visual observation , data interpretation , internal and external monitoring of equipment .
EHSQ AWARENESS POINTS AT PLOT NO. 6
Indoor air quality (IAQ) is
the air quality within buildings that affects the health and comfort of occupants
; it's influenced by factors like pollutants, temperature, humidity, and ventilation. Poor IAQ is linked to health issues such as allergies, asthma, headaches, and respiratory problems, and is often caused by pollutants like dust, mold, chemicals from cleaning products and furnishings, and smoke, which can be more concentrated indoors than outdoors. To improve IAQ, you can reduce pollutant sources, ensure proper ventilation through your HVAC system, use air purifiers or filters, and regularly clean to remove allergens and dust
Indoor ventilation is the process of moving fresh outdoor air into a building or room while circulating and removing stale, polluted air. It is essential for a healthy and comfortable indoor environment, as it controls humidity, removes contaminants, and helps regulate temperature
Typical Noise Ranges
SCADA Room:
Aim for a comfortable environment with minimal noise, typically below 40 dBA, to ensure clear communication and reduce distractions for operators.
UPS Room:
While a comfortable range is 20-25°C, UPS units can tolerate higher temperatures and generate more noise. Acceptable levels can be higher, potentially up to 65-70 dBA, depending on ventilation and equipment specifications.
Factors Affecting Noise Levels
Distance:
Noise levels decrease rapidly with distance from the source, following the inverse square law, where sound intensity reduces by half for every doubling of distance.
Ambient Noise:
When measuring noise, it's essential to account for background sounds like wind, which can make it difficult to pinpoint equipment noise.
High Temperatures:
During hot periods or when the system is under heavy load, inverters and UPS units may require fans to run at higher speeds, leading to increased noise.
Clean the air conditioning filter in a battery room .
every 2-4 weeks during peak use, or at least monthly
, due to the higher likelihood of dust, dirt, and potentially airborne particles from electrical components or other sources. The exact frequency depends on the type of filter, the specific environment of the battery room, and whether pets or other contaminants are present. A visible layer of dirt and reduced airflow are clear signs the filter needs immediate attention.
A typical battery room in a solar power plant should aim for a temperature range of
15°C to 25°C (59°F to 77°F)
and avoid high temperatures (above 35°C) to prevent electrolyte evaporation and reduce battery life. While humidity isn't specified as critically, it is crucial to maintain adequate ventilation to prevent hydrogen gas buildup, a byproduct of battery operation, which can create an explosive atmosphere.
An unsafe condition in a solar plant's main control room (MCR) can be caused by electrical failures, environmental issues, human factors, or security breaches. Hazards in the control room are particularly critical because operators rely on this central hub to monitor and manage the entire solar farm.
Security risks
Unauthorized access: Unsecured access to the control room by unauthorized personnel can lead to intentional sabotage or accidental interference with critical systems. Access must be limited and monitored.
Security system failure: A failure of the control room's CCTV or other security monitoring systems would prevent operators from detecting onsite threats, including sabotage or theft.
Remote access vulnerabilities: While remote monitoring is a key feature of modern control rooms, insecure network connections can make systems vulnerable to cyberattacks.
