Can you store chemicals in a garden shed?


The reason for not storing these chemicals in metal garden sheds is that their corrosive or reactive nature can cause the metal to deteriorate, weaken, or corrode over time. This can compromise the structural integrity of the shed and potentially create safety hazards. It's generally recommended to store these types of chemicals in a well-ventilated, non-metal storage area or cabinet designed for that purpose, following the manufacturer's instructions for proper storage and handling.

Here's a list of common household chemicals that should not be stored in metal garden sheds.

  • Fertilizers (especially those containing ammonia or ammonium compounds):
    Many fertilizers are hygroscopic, meaning they absorb moisture from the air. This moisture can cause the fertilizer to release ammonia gas, which is corrosive to metals.
  • Chlorine-based products (e.g., bleach, pool chemicals):
    Chlorine gas, which can be released from these products, is highly corrosive to metals and can cause them to rust and degrade.
  • Acids (e.g., muriatic acid, sulfuric acid):
    Acids are corrosive to most metals and can cause them to corrode and weaken over time.
  • Oxidizing agents (e.g., hydrogen peroxide, potassium permanganate):
    These chemicals can react with metals, causing them to rust and corrode rapidly.
  • Solvents (e.g., paint thinners, degreasers):
    Many solvents contain chemicals that can dissolve or degrade certain metals, leading to corrosion.
  • Pesticides and insecticides:
    Some pesticides and insecticides contain chemicals that can corrode metals, especially if they contain acids or other corrosive substances.
  • Automotive products (e.g., antifreeze, brake fluid):
    Many automotive products contain chemicals that can corrode metals, particularly if they come into direct contact with the metal surfaces.
  • Concrete and masonry products (e.g., cement, mortar mix, grout):
    These products contain compounds like calcium hydroxide, which can react with certain metals, causing corrosion.
  • Plastering compounds (e.g., joint compound, drywall mud):
    Many plastering compounds contain chemicals like ethylene glycol, which can corrode metals over time.
  • Paints and stains (especially oil-based products):
    These can contain solvents, acids, or other chemicals that can degrade and corrode metal surfaces.
  • Wood preservatives and sealants:
    Some wood preservatives contain copper compounds or other chemicals that can react with and corrode metals.
  • Rust removers and converters:
    These products often contain strong acids or chelating agents that can be highly corrosive to metals.
  • Adhesives and caulks (especially those containing solvents or acids):
    Many adhesives and caulks contain chemicals that can interact with and corrode metal surfaces.
  • Concrete sealers and waterproofers:
    Some of these products contain silicates, silanes, or other compounds that can potentially corrode certain metals.
