 An effective Environmental, Health, and Safety (EHS) Plan for a solar plant’s Operation and Management (O&M) team must be fully developed, approved, and implemented at least 30 to 60 days prior to the Provisional Acceptance (PAC) or First Time Energization/Commissioning. This ensures all safety systems, trained personnel, and procedures are in place for the transition from construction to operations.

EHS Plan & Manual Structure for O&M

The EHS manual for the O&M phase should focus on active operational risks, differing from construction-focused safety documents. Key components include: 

Safety Management System (SMS): Leadership commitment, hazard ID, risk assessment (HAZID), and contractor safety management.

Operational Controls: Lockout/Tagout (LOTO) procedures, Electrical Safety Rules (especially high voltage), and Fall Protection for roof/structure maintenance.

Environmental Management: Waste management (panel disposal, e-waste) and spill prevention.

Emergency Response: Procedures for fire, electrocution, or severe weather.

Document Control: Site-specific safety plans, daily inspection logs, and incident reporting procedures. 

Time Framework Before First Time Acceptance 

The following timeline should be followed for ensuring the EHS readiness:

Timeline Milestone Key EHS Actions

T-90 Days Pre-Acceptance Phase Identify site-specific hazards (electrical, fire, height). Conduct gap analysis between construction safety and O&M requirements.

T-60 Days EHS Manual Finalization Finalize the O&M EHS manual based on as-built designs.

T-45 Days Equipment & Procedures Procure necessary Personal Protective Equipment (PPE) and Safety tools (e.g., test meters). Establish Permit to Work (PTW) systems.

T-30 Days Training & Induction Complete specialized safety training for the O&M team (Electrical safety, First Aid, Firefighting).

T-15 Days Final Audit/Trial Perform a pre-commissioning safety audit to ensure all safety measures are in place.

Maximizing energy efficiency after cleaning Trina Solar modules and string inverters involves a combination of thorough post-cleaning inspection, technical verification of the inverter's maximum power point tracking (MPPT), and, if necessary, applying specialized coatings to maintain performance

 Shri SKV Valli sir continously monitoring modules cleaning quality & ensuring safety.

Maximizing energy efficiency after cleaning Trina Solar modules and string inverters involves a combination of thorough post-cleaning inspection, technical verification of the inverter's maximum power point tracking (MPPT), and, if necessary, applying specialized coatings to maintain performance. Dirty panels can lose up to 25% efficiency; cleaning restores this, but subsequent maintenance ensures long-term gains. 

Here are the specific methods for improving energy efficiency post-cleaning:

1. PV Module Performance Optimization

Post-Cleaning Inspection: Inspect modules for remaining residue, cracks, or scratches caused by cleaning, as scratches can create new shading spots.

Apply Anti-Soiling/Hydrophobic Coatings: Applying hydrophilic or hydrophobic coatings to Trina Solar modules helps repel water and dust, maintaining high light transmittance and preventing dirt accumulation, which can boost efficiency by 5–6%.

Optimize Tilt Angle: If the modules are on an adjustable rack, ensure they are at the optimal tilt angle for the current season to enhance self-cleaning and maximize solar radiation, minimizing long-term dust buildup.

Use Proper Cleaning Materials: Use deionized water or water with low mineral content to prevent deposits that reduce light absorption. 

2. String Inverter Optimization

Clear Air Vents/Fans: Clean the inverter's cooling fans and vents with a soft brush or compressed air to prevent overheating, which can reduce inverter efficiency.

Verify MPPT Tracking: After cleaning, the sudden increase in DC power might require the inverter to recalibrate. Monitor the string inverter via its app/web portal to ensure it is effectively tracking the new maximum power point.

Firmware Updates: Check with the manufacturer (e.g., Sungrow, Huawei, or the specific brand used with Trina) for firmware updates, which often optimize MPPT algorithms and improve conversion efficiency.

Inspect Electrical Connections: Check DC cables and connectors for corrosion or loose connections that cause resistance losses, especially after the increased load post-cleaning. 

3. Monitoring and Maintenance

Establish a New Baseline: Record the daily and peak AC power output immediately after cleaning. This new, high-performance baseline allows for accurate future monitoring.

Utilize Real-Time Monitoring (SCADA/Apps): Use tools to track the Power Ratio (PR) of the system. If performance drops by more than 10% below the post-cleaning baseline, re-evaluate for potential issues.

Regular Shading Audit: Trim trees or remove obstacles that may have grown and are casting shadows on the newly cleaned module.

4. Optimal Timing

Clean Early/Late: Clean modules in the early morning or late evening when they are cool, reducing the risk of thermal shock and allowing for a better inspection of the surface.

By implementing these steps, you can ensure that the 15%–30% increase in power gained from cleaning is maintained, maximizing the return on investment (ROI) for the Trina Solar system.

The implementation of the Occupational Safety, Health and Working Conditions (OSH) Code, 2020, which went into full effect on November 21, 2025, marks a major overhaul of India's labour laws, replacing 13 older laws with a unified, modern, and digital-first framework.

 The implementation of the Occupational Safety, Health and Working Conditions (OSH) Code, 2020, which went into full effect on November 21, 2025, marks a major overhaul of India's labour laws, replacing 13 older laws with a unified, modern, and digital-first framework.

This implementation across all industries—including the rapidly growing solar sector—aims to improve safety standards, enhance worker welfare, and ease compliance. 

Why the OSH Code 2025 is Implemented (General Industry)

Universal Coverage and Standardization: The code extends mandatory health, safety, and working conditions to all sectors, moving beyond the previous limitations of specific sectors (factories, mines, etc.). It applies to any establishment with 10 or more workers and even with one employee in hazardous occupations.

Simplified Compliance ("Ease of Doing Business"): It replaces complex, fragmented regulations with a single registration, a single license, and a single annual return. The number of registers is reduced from 84 to 8.

Digital Inspections and "Inspector-cum-Facilitator": The traditional, intrusive "inspector raj" is replaced by a web-based, randomized inspection system. Inspectors act as facilitators to guide compliance rather than just policing.

Pro-Worker Provisions:

Free Annual Health Check-ups: Mandatory for employees.

Appointment Letters: Compulsory for all employees, ensuring transparency.

Right to Refuse Dangerous Work: Workers are empowered to refuse work that threatens safety without fear of penalties.

Women in All Sectors/Night Shifts: Women can work in all sectors, including night shifts, with proper safety and consent.

Contract Labour and Migrant Workers: The Code increases responsibility on the principal employer to ensure safety and welfare of contract workers, and extends travel allowances and benefits to migrant workers. 

Why the OSH Code 2025 is Vital for Solar Plants

Solar plants (both manufacturing and utility-scale projects) are treated as high-risk construction/manufacturing sites. The 2025 implementation is critical for this sector because: 

Hazardous Operations & Safety Standards: Solar plants involve working with high-voltage electricity, high-temperature equipment (in manufacturing), chemical handling, and construction work, all of which fall under the enhanced safety protocols of the new Code.

Mandatory Risk Assessment: The Code requires comprehensive risk assessments, safety committees (for establishments with 500+ workers), and mandatory safety training for workers handling machinery and electrical components.

Safety of Contractual Labour: Given that many solar projects rely oncontractors, the code places the responsibility on the principal employer (the solar plant owner) to provide necessary welfare, first aid, and safety equipment (PPE).

Specific 2025 Quality Control Order (QCO): In addition to the OSH Code, the MNRE (Ministry of New and Renewable Energy) notified a Solar Systems, Devices, and Components Goods Order, 2025, effective from mid-2025. This requires mandatory BIS certification, and sets minimum efficiency standards (17-18%) for PV modules, inverters, and storage batteries, ensuring both safety and high performance.

Environmental and Safety Compliance: The code mandates strict safety measures for the handling and disposal of hazardous waste, such as damaged panels or toxic battery component.

Key Changes Affecting 2025

Decriminalization of Minor Offences: Replaces imprisonment with financial penalties (compounding) for first-time offences, encouraging voluntary compliance.

48-Hour Work Week: Standardizes working hours to 8 hours a day/48 hours a week, with double the wages for overtime. 

Note: While the code was enforced nationally on Nov 21, 2025, full implementation depends on state-specific rules. 

🚧 SAFETY TALKS | ACCIDENT PYRAMID (Accident Triangle Theory)

 🚧 SAFETY TALKS | ACCIDENT PYRAMID (Accident Triangle Theory) 🚧

Every serious accident starts small — and that’s exactly what the Accident Pyramid reminds us.

At the base of the pyramid are unsafe acts, unsafe conditions, and near misses. When these early warning signs are ignored, they stack up and can eventually lead to lost time injuries, permanent disabilities, or even fatalities.

🔺 The message is clear:

👉 Control the base of the pyramid, and you prevent the top.

In high-risk industries like Oil & Gas, Construction, Manufacturing, and Industrial Operations, safety isn’t just about reacting to injuries — it’s about preventing them before they happen.

⚠️ What this means for everyone on site:

✅ Report unsafe acts and conditions immediately

✅ Take near-miss incidents seriously — they are free lessons

✅ Fix hazards early, before someone gets hurt

✅ Follow PPE and safe work procedures at all times

✅ Speak up - safety is everyone’s responsibility

🛑 One unreported near miss today can become a fatal accident tomorrow.

Let’s stop incidents at the base, protect our people, and build a strong safety culture together.

💬 Safety is not a priority — it’s a value.

Key EHSQ Patrolling & Prevention Strategies

 High-tension (HT) transmission line patrolling to mitigate monkey-related fatalities is a critical environmental, health, safety, and quality (EHSQ) initiative. Monkeys, especially in forested or semi-urban areas, are attracted to poles and often bridge the gap between phases or between a phase and a grounded component, resulting in fatal electrocution, line faults, and outages. 

Key EHSQ Patrolling & Prevention Strategies

Identify Hotspots: Patrol crews must identify high-risk sections where monkeys are frequent, particularly where power lines are close to treetops.

Install Physical Barriers: Install anti-climbing devices like conical guards or metal sheeting around the base of poles to prevent monkeys from climbing.

Insulate Conductors: At identified hotspots, wrap exposed wires, transformers, and switches with insulating materials like silicone covers, PVC, or rubber shrouds to prevent contact.

Tree Trimming: Trim branches that overhang or are close to power lines, which act as bridges for monkeys to reach the lines.

Install Wildlife Deterrents: Utilize non-harmful,, auditory or visual deterrents (e.g., predator effigies) to keep wildlife away from critical infrastructure.

Underground Cabling: In high-risk, sensitive forest areas, replacing overhead lines with underground cables is the most effective, albeit expensive, long-term solutio

Emergency Response and Maintenance

Immediate Reporting: Patrolling staff should promptly report any sightings of monkeys on poles, carcasses, or injuries to local wildlife authorities.

Safe Rescue Procedures: Establish protocols for rescue teams to safely handle electrocuted animals, often requiring the temporary de-energizing of lines.

Routine Inspections: Regular inspections must include checking for damaged insulators, nests, or carcasses, which indicate high activity zones. 

EHSQ Documentation

Maintain accurate records of monkey electrocutions to analyze trends and identify areas requiring retrofitting.

Implement a "before and after" monitoring system to evaluate the effectiveness of installed insulators and barriers.

Using specialized silicone line covers, which can withstand high voltages and harsh weather, has been highly effective in protecting wildlife and reducing power outages caused by animal contacts. 

This standard operating procedure (SOP) is based on general industry guidelines for cleaning photovoltaic modules, with specific attention to the requirements often specified for Trina Solar bifacial dual-glass modules

 

Based on typical photovoltaic (PV) module cleaning guidelines for anti-reflective coated glass, including recommendations often cited for high-quality modules like those from Trina Solar, the following water quality standards should be met to prevent damage and optimize performance. 

Recommended Water Quality Parameters

 pH Range: 5.0 – 7.0 (Note: Some guidelines accept slightly broader ranges of 6.5–8.5, but lower, near-neutral, or slightly acidic water is safer for coated glass to prevent scaling).

Total Dissolved Solids (TDS): \ 1000 mg/L. For optimal results, lower is better (e.g., \(<30\) mg/L) to prevent mineral deposits.

Water Hardness (Calcium & Magnesium ions): 0 – 40 mg/L (soft water).

Chloride/Salinity: 0 – 3,000 mg/L.

Turbidity: 0 – 30 NTU. 

 Cleaning Requirements Water Type: Non-alkaline water must be used. Demineralized or Reverse Osmosis (RO) water is highly recommended to avoid residues.Hard Water Caution: Use of hard water (\(>75\) mg/L - \(180\) mg/L) is prohibited on Anti-Reflective Coated (ARC) modules as it can cause scaling, which reduces efficiency.Water Pressure: Maximum water pressure at the nozzle should not exceed 4 MPa (40 bar).Water Temperature: The temperature of the water should be close to the ambient temperature of the panel to avoid thermal shock.Cleaning Time: Early morning or late afternoon (dusk/dawn) when panels are cool.Avoid: Do not use alkaline or strong acid solvents.  — Water quality: The quality of water is crucial when cleaning solar modules. High mineral content water may cause mineral deposits on the glass surface, reducing. 

This standard operating procedure (SOP) is based on general industry guidelines for cleaning photovoltaic modules, with specific attention to the requirements often specified for Trina Solar bifacial dual-glass modules.

1. Pre-Cleaning Preparation

Time of Day: Clean only during low-light conditions (early morning, evening, or overcast days) to avoid high electricity generation (safety) and to prevent thermal shock.

Personnel Safety: Wear personal protective equipment (PPE), including insulated gloves and safety glasses.

System Status: Turn off the PV system before beginning the cleaning process.

Do Not Walk/Stand on Modules: Do not stand, step, or sit on the modules to avoid breaking the glass, especially with delicate dual-glass bifacial modules.

2. Water Quality Requirements

Using improper water can cause mineral deposits (scaling) or scratch the Anti-Reflective Coating (ARC) on the glass. 

Preferred Water Type: Reverse osmosis (RO) water or deionized water.

Alternative: Clean rainwater or tap water with low mineral content (Total Hardness < 75 mg/L or < 60 mg/L).

Total Dissolved Solids (TDS): Should be less than 400 mg/L (some guidelines suggest < 30mg/L).

pH Level: 6.5 to 7.5 (near neutral).

Forbidden: Do not use high-pressure, hard water, or water containing harsh chemicals (acids, alkalis, acetone).

3. Module Temperature and Thermal Shock Prevention

Temperature Differential: The water temperature must be similar to the module temperature at the time of cleaning.

Maximum Difference: The water should not be more than 20°C warmer or colder than the module surface temperature to avoid breaking the glass due to thermal shock.

Avoid Hot Panels: Do not spray cold water on hot, sun-exposed panels. 

4. Wet Cleaning Method (Step-by-Step)

Remove Loose Dirt: Use a low-pressure water spray to remove dust and loose dirt.

Apply Water/Detergent: If stubborn dirt remains, use water mixed with a mild, non-abrasive detergent or, preferably, just water.

Scrubbing: Use a soft-bristled brush, sponge, or soft microfiber cloth to clean the surface.

Cleaning Direction: Start from the top row and work downwards.

Stubborn Stains: Soak the stain rather than scrubbing harshly to avoid damaging the Anti-Reflective Coating (ARC).

Backside Cleaning: For bifacial modules, the back glass should be cleaned using the same gentle methods to maintain high energy yields.

Rinse: Rinse the modules thoroughly with plenty of water.

Drying: Use a squeegee or lint-free cloth to remove excess water and prevent streak/spotting. 

5. Water Pressure

Maximum Pressure: Water pressure should not exceed 35 bar (or 4 MPa) at the nozzle.

Equipment: Use a soft nozzle or low-pressure spray attachment. 

6. Post-Cleaning

Inspection: Inspect modules for cracks, scratches, or damage.

Documentation: Record the cleaning date, water type used, and any noted damage. 

EHSQ Technical awareness

 

Most organizations don’t have a safety culture. They have a reporting culture.

 Most organizations don’t have a safety culture.

They have a reporting culture.

Let’s be honest.

☠️ Toxic safety culture looks like this:

 • “Zero Accident” targets → zero reporting

 • Incidents = Who failed?

 • Near misses hidden to protect reputations

 • Human error labeled as the root cause

 • PPE used to compensate for poor design

 • Safety officers with responsibility but no authority

 • Audits chasing scores, not risks

 • Workers told to “be careful” in unsafe systems

🌱 Healthy safety culture looks very different:

 • Reporting is rewarded, not punished

 • Incidents ask What failed in the system?

 • Near misses are treated as free lessons

 • Human error is a signal, not a cause

 • Engineering controls come before PPE

 • Safety professionals have real decision power

 • Audits expose weaknesses early

 • Systems are designed to support humans

Here’s the line most leaders don’t want to hear:

A toxic safety culture asks people to be careful.

A healthy safety culture makes it hard to get hurt.

If your safety dashboard looks perfect…

but people are afraid to speak up —

you don’t have safety.

You have silence.

💬 Uncomfortable question:

Would your people report a serious near miss today — without fear?

If not, it’s time to stop celebrating numbers

and start fixing systems.

SAFETY MOMENT | MOBILE PHONE USE WHILE WALKING ON SITE 📱

 🚧📱 SAFETY MOMENT | MOBILE PHONE USE WHILE WALKING ON SITE 📱🚧

Distractions at worksites can turn ordinary tasks into serious incidents in seconds.

📍 Scenario Observed:

A worker was seen walking through an active construction area while using a mobile phone—unaware of moving vehicles, forklifts, and heavy equipment nearby.

⚠️ Why this matters:

Using a phone while walking reduces situational awareness and increases the risk of: • Being struck by vehicles or equipment

• Slips, trips, and falls

• Serious injuries or fatalities

🗣️ What should we do when we see this?

✅ Intervene immediately

✅ Ask the person to stop walking while answering or making calls

✅ Discuss the hazards and potential consequences on site

🛠️ Corrective & Preventive Actions:

✔️ Stop walking when using a phone

✔️ Use designated phone-use areas only

✔️ Stay alert and aware of surroundings

✔️ Always follow pedestrian walkways

🚨 Safety Rule to Remember:

❌ If answering phone calls or texting – STOP

✅ No Calls + No Texting = No Walking

Let’s keep our focus where it matters most—on safety. One moment of awareness can prevent a lifetime of consequences.

👷‍♂️👷‍♀️ Stay alert. Stay visible. Stay safe.

Fire hazard management

 Fire hazard management

From Reaction to Prevention

Organization methodology according to ISO 9001:2015

Fire accidents are rarely "sudden incident".

In fact, it is the result of failing systems, human errors, weak regulations.

By applying CAPA (Corrective and Preventive Measures) methodology, fire management can be transformed from emergency response to strategic risk management.

⸻

🔥 Stage One: Immediate Actions (Correction)

Goal: Protect lives first, then assets and keep operation going.

Main Procedures:

• Firefighting: Operating fire systems (Sprinklers – Fire Extinguishers – Fixed Systems).

• Evacuation: Ensuring the safety of individuals, executing the count, and verifying accountability.

• Containment: Isolate the affected areas to prevent the spread of fire.

• Reporting: Civil defense notice, insurance companies, and higher administration.

✅Focus: safety of lives first, reduction of losses second.

⸻

🔍 Phase 2: Root Cause Analysis

The goal: Find out why the fire started — not just what happened.

TOOLS OF INVESTIGATION:

• Technique 5 Whys

• Fishbone (Ishikawa) cause and effect chart

 • Fault Tree Analysis (FTA)

 • Failure Mode and Effects Analysis (FMEA)

Common causes of structure fires:

• Electrical malfunctions and infrastructure collapsing

• unsafe storage of flammable materials

• Poor maintenance of heating or cooking equipment

• Human error (smoking, unauthorized hot acts)

• Deliberate combustion or destruction

• Natural causes (lightning, forest fires)

✅Focus: Decisions based on systematic analysis, not assumptions.

⸻

🛠️ Stage 3: Corrective Actions

Goal: Remove existing sources of danger and close the weaknesses in the system.

An example of actions:

• Repair/replacement: electrical systems and damaged equipment.

• Reorganizing: Storage areas to improve access and create fire breaks.

• Retraining: Emergency Response and Risk Awareness Workers.

• Reinforcement: Fire resistant insulation and constructive partitioning.

• Recovery: Continuity of business through backup systems and alternative locations.

✅Focus: Addressing technical and behavioral failure together.

⸻

) Fourth stage: Preventive Actions

Goal: Prevent accidents from recurrence through preventive measures.

🔧 Engineering regulations

• Automatic detection, warning and extinguishing systems

• Thermal cameras and early warning systems

• Suitable distances and ventilation for heat generating equipment

• Safe and updated electrical design

📋 Administrative terms

• Patrol assessments for fire hazard

• Preventive maintenance programs

• Hot Work Permit System (Hot Work Permit)

• Strict standards for cleanliness and orderliness (Housekeeping)

• Evacuation drills and business continuity plans

🌍 Operational flexibility and supply chains

• Geographical diversification of critical operations

✅Focus: Eliminating Hazard from design before accident occurs.

⸻

📊 Fifth Stage: Verification & Monitoring (Verification & Monitoring)

Goal: To ensure CAPA is effective and continuous improvement.

Performance Indicators (KPIs):

• Average time between fire incidents

• A time of discovery and response

• Commitment rate to preventive maintenance

• The number of business continuity tests

The R U N G :

• Patrol reviews from the higher administration

• Internal and external audits

• Ongoing update of CAPA procedures

✅Focus: What is being measured... It can be controlled.

⸻

💡 the conclusion

Fire management is not just equipment —

Rather an integrated system, culture, and risk-based decisions.

ISO 9001 no fire prevent,

But correct application of CAPA prevents it from repeating

Copied for the benefit 

To provide supervisors, engineers, and HSE personnel with simple, practical methods to motivate workers to follow safe work practices, actively participate in HSE programs, and contribute to a positive safety culture on site.

 Practical Ways to Motivate Workers on Site

Purpose

To provide supervisors, engineers, and HSE personnel with simple, practical methods to motivate workers to follow safe work practices, actively participate in HSE programs, and contribute to a positive safety culture on site.

1. Lead by Example

Supervisors and managers must always comply with HSE rules

Wear PPE correctly and consistently

Follow site procedures without shortcuts

Workers are more motivated when leaders practice what they preach.

2. Recognize and Appreciate Safe Behavior

Acknowledge workers who follow safe work practices

Recognize near-miss reporting and hazard identification

Use simple recognition such as verbal praise, certificates, or notice board mentions

Recognition reinforces positive behavior and builds morale.

3. Involve Workers in Safety Activities

Ask workers for input during risk assessments and toolbox talks

Encourage suggestions for safer work methods

Appoint safety champions or representatives from work crews

Involvement creates ownership and accountability.

4. Conduct Engaging Toolbox Talks

Keep toolbox talks short and focused

Use real site examples, not only procedures

Encourage two-way discussion instead of one-way instruction

Interactive sessions keep workers interested and motivated.

5. Act on Reported Hazards and Near Misses

Respond promptly to reported safety issues

Provide feedback on actions taken

Close reported items visibly and communicate outcomes

When workers see action, they stay engaged.

6. Provide Proper Training and Support

Ensure workers are trained for their specific tasks

Conduct refresher training regularly

Pair new or young workers with experienced personnel

Confidence in skills leads to safer behavior.

7. Maintain Fair and Consistent Discipline

Apply HSE rules equally to all levels

Focus on correcting behavior, not blaming

Use disciplinary action only when necessary and fairly

Consistency builds trust and respect.

8. Improve Welfare and Working Conditions

Ensure access to drinking water, rest areas, and sanitation

Maintain good housekeeping

Provide suitable tools and equipment

A safe and comfortable environment motivates workers naturally.

9. Encourage Teamwork and Peer Support

Promote looking out for one another

Encourage workers to stop unsafe acts politely

Reinforce that safety is a shared responsibility

Strong teams create safer sites.

10. Monitor and Reinforce Continuously

Observe behavior regularly

Provide positive feedback immediately

Reinforce key safety messages daily

Motivation is ongoing, not a one-time activity.

Conclusion

Worker motivation is built through respect, involvement, recognition, and consistent leadership. Practical actions taken daily by supervisors and managers have the greatest impact on safety performance. Motivated workers protect themselves, their colleagues, and the project.

Good housekeeping helps to reduce: * Slips, trips, and falls *Fire risks *Damage to tools and equipment

 Housekeeping 

A Clean Site Is a Safe Site

Good housekeeping helps to reduce:

* Slips, trips, and falls

*Fire risks

*Damage to tools and equipment

An untidy workplace is more than just an eyesore — it is unsafe.

Key Safety Reminders

*Keep all walkways free from obstructions

*Wipe up spills as soon as they occur

*Stack and store materials correctly

*Dispose of waste only in approved bins

*Roll up hoses and cables after use

Why This Is Important

Many serious injuries begin with small issues such as:

*Loose debris

*Oil or grease on the floor

*Tools left lying around

When minor hazards are ignored, they can quickly turn into major accidents.

Worker Engagement Question

What is one item or area we can improve, clean, or organize better today?

Closing Safety Message

Always leave your work area safer and cleaner than you found it.
