Common fire hazards include flammable liquids, gases, combustible dust, and electrical equipment. Properly labelling and cataloguing these materials can help identify potential safety risks.

Fire hazards can result in devastating incidents such as laboratory fires, explosions, and severe burns to personnel. These events can cause extensive property damage, loss of experimental data, and, in severe cases, fatalities. Smoke inhalation and exposure to toxic fumes during a fire can also lead to respiratory issues and other health complications.

Preventive Measures

  • Proper Storage: Storing flammable materials correctly is crucial in minimising fire hazards. Use approved safety containers, keep materials in designated flammable storage cabinets, and segregate flammables from incompatible substances to prevent dangerous reactions.

  • Safe Handling Techniques: Avoid open flames, ensure proper ventilation, and always wear appropriate PPE such as flame-resistant lab coats, gloves, and safety goggles, to protect against accidental fires.

3. Inhalation of Toxic Gases

The inhalation of toxic gases poses severe health hazards in the laboratory environment.

It is a significant hazard in labs, as many experiments and procedures involve substances that can release harmful vapours.

These gases can include solvents, reagents, and byproducts of chemical reactions. Exposure to toxic gases can lead to immediate health effects such as dizziness, headaches, respiratory distress, and in severe cases, loss of consciousness or death. Chronic exposure can result in long-term health issues like respiratory diseases, neurological damage, and cancer.

Toxic gases can be released due to improper handling of chemicals, accidental spills, inadequate ventilation, or equipment malfunctions. Even small amounts of certain gases can be hazardous, making it crucial to recognise and control these risks.

Given the acute and chronic health effects these gases can cause, implementing appropriate control measures to protect lab workers is of utmost importance.

Preventive Measures

Implementing the following risk control measures can significantly reduce the risk of inhaling toxic gases in the laboratory:
