Study Notes

Laboratory Symbols and Their Descriptions

Set 1

  • Biohazardous materials signal potential risk to health and environment.
  • Organisms that pose minimal infection hazard with effective treatments.
  • Presence of possibly hazardous materials or environments indicated.
  • Moderate risk organisms that are less contagious but require effective treatment.
  • High flammability risk area; avoid open flames due to sensitive materials.
  • Chemical, physical, or biological factors that can adversely affect health.
  • Area for photo-sensitive materials requires low light conditions.

Set 2

  • Carcinogenic materials pose significant long-term health risks.
  • Corrosive substances can cause severe damage upon contact.
  • Harmful chemicals lead to irritation of skin or respiratory systems.
  • Working with high-voltage electricity increases risk of dangerous shocks.
  • Open hair prohibited to minimize hazards while working.
  • Use of electronic devices is restricted to avoid interference or hazards.
  • Toxic materials denote acute health risks and require strict handling protocols.

Set 3

  • Gloves must be removed to prevent contamination or accidents.
  • Emergency meeting area for lab personnel in case of incidents.
  • Combustible materials should be handled with caution due to fire risk.
  • Presence of explosive or self-reactive substances requires special precautions.
  • Risk of electric shock from devices with potential mild to severe consequences.
  • Oxidizing chemicals can greatly increase fire risk and should be stored carefully.
  • Special low-temperature zones require appropriate handling procedures.

Set 4

  • Non-ionizing electromagnetic waves can excite electrons, though not harmful.
  • Radioactive materials emit ionizing radiation; strict controls are necessary.
  • Showers provided for decontamination or cleaning up hazardous materials.
  • Risk of burns from hot surfaces or equipment necessitates caution.
  • Laser radiation requires protective measures to prevent injury.
  • Broken glass poses physical hazards and requires careful disposal.

Set 5

  • Use of face shields is mandatory to protect against splashes or debris.
  • Protective gloves are essential in certain areas to safeguard skin.
  • Safety goggles must be worn to shield eyes from hazardous materials.
  • Closed-toe shoes are required to protect feet in the lab environment.
  • Breathing masks/respirators are necessary in contaminated air situations.
  • Hair protection measures are needed to prevent contamination in the workspace.
  • Full protective clothing is required for maximum safety in hazardous areas.

Set 6

  • Fire blankets are stored in specific locations for emergency use.
  • A bell must be pressed to alert personnel during emergencies like fires.
  • Fire extinguishers are strategically located for quick access when needed.
  • Access to certain areas is restricted to authorized personnel only.
  • Hoses with water or fire retardants are essential for firefighting efforts.
  • Eating or drinking is prohibited in the laboratory to prevent contamination.
  • First aid boxes and materials should be readily available for emergencies.
