Chemical Storage

The safe storage of hazardous chemicals is a very important aspect of any chemical safety program. At KFUPM, the laboratories and other work areas where chemicals are used must follow the safe storage requirements such as:

  • Keep an up to date chemical inventory
  • Maintain a chemical hygiene plan
  • Document staff training
  • Conduct annual self-inspection

Chemical Inventory:

A chemical inventory is the first step towards safe storage of chemicals. A well-maintained inventory will apprise the faculty, staff, and students about the dangers in the laboratory or work area. It also helps the emergency response teams to respond effectively in case of fire or chemical release in the work area. The chemical inventory must be reviewed annually, and unwanted chemicals must be disposed through a standard procedure.

Labeling Chemicals:

  • All the hazardous chemicals must be labeled as per the Globally Harmonized System (GHS).
  • The labels must be clear and legible.
  • Damaged labels must be replaced.
  • Working solutions prepared in the lab must also be labeled, clearly indicating its hazards to warn other colleagues.
  • Storage area, storage cabinets must also be labeled clearly as per their chemical family or hazard classification.


  • Chemicals should be segregated and stored as per their chemical family or hazard classification.
  • Chemicals should not be stored alphabetically unless they are compatible.
  • Storing incompatible chemicals together may result in fire and explosion, or other harmful reactions.
  • One chemical family should be separated from the other through a non-combustible partition, or by maintaining a standard safe distance.
  • Flammable liquids should be stored in standard flammable storage cabinets.
