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.
