CPCB Environmental Compliance Signs for Indian Factories: Pollution Control and Waste Management

Environmental Signs: The Forgotten Compliance Category

Most factories focus their signage efforts on worker safety — PPE signs, fire signs, emergency signs. But there is another category of mandatory signs that often gets overlooked: environmental compliance signage required by the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs).

CPCB/SPCB Required Signs

Hazardous Waste Storage

Under the Hazardous and Other Wastes (Management and Transboundary Movement) Rules 2016:

• "Caution: Hazardous Waste Storage Area" at the entry of every TSDF (temporary storage and disposal facility)
• Waste category identification signs — identifying the waste code and description per CPCB schedule
• "No Smoking / No Naked Flame" in hazardous waste areas
• Emergency spill procedure boards
• PPE requirements for waste handling
• "Authorised Personnel Only"

ETP (Effluent Treatment Plant) Signage

• Process flow identification signs — each tank/stage of the ETP
• Chemical storage signs (for treatment chemicals: alum, poly-electrolyte, lime, acid, alkali)
• "Caution: Open Tank — Fall Hazard"
• "Biological Hazard — Treated/Untreated Effluent"
• Discharge point identification

STP (Sewage Treatment Plant) Signage

• Similar to ETP signage
• "Treated Water — Not Potable" — for recycled water outlets
• Colour-coded pipe identification for recycled water (typically purple per IS standard)

Emission Monitoring

• CEMS (Continuous Emission Monitoring System) identification board at the stack
• "Stack Emission Monitoring Point"
• Consent to operate details display (some SPCBs require this)

Waste Segregation Signs

Under the Solid Waste Management Rules 2016 and BMW (Bio-Medical Waste) Rules:

• Colour-coded waste bin identification — Green (biodegradable), Blue (recyclable), Black (non-recyclable), Red (hazardous/biomedical)
• Pictogram and text for each bin category
• "Do Not Mix Waste — Segregate at Source"
• E-waste collection point signs — per E-Waste Management Rules

Display Board Requirements

Many SPCBs require factories to display:

• Consent to Operate (CTO) board — displaying consent number, validity, and consented parameters
• Environmental policy display
• Emergency environmental response contacts
