Rules for Safe Handling of Chemicals

The risks associated with handling and storing material in the laboratory can be significantly minimised by following a few basic guidelines that are mentioned in the Fire and safety Course in Chennai.


  • Containers should be labeled with the date, month, and year they were first opened and received. This is expected for organic peroxide-forming materials and recommended for all others.
  • Chemical storage should be limited to only certain substances that would be regularly used in laboratories. The doors to the laboratory should be kept shut at all times.
  • If workers have not been qualified to use chemicals or tools, they should not use them.
  • For work with specific chemical hazards, follow the chemical storage guidelines suggested by NEBOSH Course in Chennai.

Chemical Safety Guidelines in General – 


  • Large bottles of acids should be kept in acid cabinets or a cabinet called “corrosives” on low shelves or trays as implied by the modules of the IOSH Course in Chennai.
  • Distinguish between oxidising and organic acids, as well as flammable and combustible products.
  • Separate acids from bases, as well as active metals like sodium, potassium, and magnesium, and other incompatible substances.
  • To carry acid bottles, use bottle carriers or a cart.
  • In the event of a spill, have spill prevention pillows or acid neutralizers on hand. To neutralise an acid spill, do not use bases.

The bases


  • Distinguish bases from acids and other incompatible substances.
  • Big bottles of liquid bases should be held on trays in a cabinet labelled “Bases” or “Corrosives.”
  • Inorganic hydroxide solutions should be held in polyethylene tanks.
  • For caustic spills, have spill prevention pillows or caustic neutralizers on hand. Acids should not be used to neutralise base spills.



  • Flammable liquids can only be kept in a specially designed flammable-safe refrigerator or flammables cabinet.
  • Keep a safe distance from ignition sources.
  • Make sure you have fire extinguishers and spill-control devices on hand.
  • Keep a Class-D fire extinguisher on hand for flammable metals. For more details, look up “fire extinguishers.”
  • Oxidizers are substances that reduce the amount of oxygen in the air.
  • Keep in a cool, dry place.
  • Keep it away from flammable and combustible materials like paper and wood.

Chemicals that make peroxide


  • When the container is obtained and when it is opened, put a date on it.
  • Keep in an airtight container in a dim, cool, and dry place.
  • As required, use sufficient indicator strips to check for the formation of peroxides in the container.
  • Peroxide-forming chemicals should be disposed of before the expiration date or one year after opening, whichever comes first.

Gases in Compression


  • Many Safety Audit Consultants suggest you place the gases in a dry, upright spot.
  • Person chain cylinders, 2/3 to 3/4 from the floor
  • Replace the valve cap when not in use.
  • Using a cylinder cart to carry.
  • Before moving the cylinder, remove all manifolds and regulators, lock the valve cap, and chain or tie the cylinder to the cart.
