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.
