Prohibited Activities in Light Industrial Zones (M1 / I-1 / LI)
Light industrial areas restrict activities that generate excessive noise, pollution, or hazards to ensure compatibility with nearby commercial or residential developments.

• Heavy manufacturing such as steel mills or chemical plants
  
• Storage or use of explosive or flammable materials
  
• Operations involving significant emissions, toxic waste, or high traffic volumes
  

Prohibited Activities in General Industrial Zones (M2 / I-2 / GI)
Although more flexible, medium industrial zones still restrict activities that pose severe environmental or safety risks or require extensive regulatory oversight.

• Slaughterhouses or meat rendering plants
  
• Nuclear material processing or disposal
  
• Large-scale landfills or hazardous waste incineration
  

Prohibited Activities in Heavy Industrial Zones (M3 / I-3 / HI)
Even in the most permissive industrial zones, certain high-risk or incompatible uses may be banned to ensure regional safety, environmental standards, or land use alignment.

• Residential developments and public facilities like schools or hospitals
  
• Open-air burning or uncontrolled emissions release
  
• Unlicensed handling of radioactive, biohazardous, or illegal substances
