Identification of Potential Hazards

In the campus laboratory, there have been cases of accidental disasters such as ingestion of chemical substances, leakage of harmful chemicals, electric shock incidents, and explosions due to improper disposal of waste liquids or mishandling of high voltage. The causes of these accidents can be attributed to non-compliance with standard usage or operating procedures, failure to adhere to safety and health regulations, or tragic events occurring without awareness of the hazards. The hazards in a typical laboratory can be categorized into three main types:

• Harms caused by human factors: Account for the majority of disaster cases, resulting from unsafe actions and behaviors.
• Harms caused by substances and energy: Including electric shock, radiation, hazardous substances, toxic materials, bacterial infections, etc.
• Harms to the environment: Such as disposal of used needles, excess chemical substances, and the handling of laboratory waste liquids.
