1. FIRST AID MEASURES
-
Chemical Splash to Eyes: If a biological or chemical sample splashes into the eyes during operation, immediately flush the eyes with copious amounts of water or sterile saline for at least 15 minutes, holding the eyelids open. Seek immediate medical attention.
-
Skin Contact with Chemical Sample: Remove contaminated clothing at once. Wash the affected skin area with soap and water for at least 5 minutes. If irritation, redness, or signs of chemical burn develop, seek medical evaluation. Refer to the Safety Data Sheet (SDS) for the specific chemical involved.
-
Sharps Injury (Broken Glassware): If a broken vessel punctures the skin, allow the wound to bleed freely (do not squeeze). Wash the wound with soap and water for 15 minutes. Apply antiseptic and a sterile bandage. If the vessel contained patient biological material, follow the facility’s exposure management protocol for bloodborne pathogens. Seek medical evaluation for potential exposure.
-
Inhalation of Chemical Vapors: If vapors from volatile reagents are inhaled during sample preparation or stirring, move the affected person to fresh air immediately. If breathing is difficult, administer oxygen if trained. If breathing stops, perform CPR. Seek immediate medical attention if coughing, dizziness, nausea, or respiratory distress persists.
-
Electrical Shock: If an electrical shock incident occurs, disconnect power at the circuit breaker before attempting to assist the victim. Do not touch the victim until the power is disconnected. Call emergency medical services immediately. Perform CPR if trained and necessary. Seek medical evaluation for all electrical shock victims, even if symptoms appear mild.
2. FIRE FIGHTING MEASURES
-
Flammability: The metal housing is non‑combustible, but the power cord, internal wiring, electronic components, and plastic control panels are combustible. Do not operate near flammable solvents, gases, or volatile materials (e.g., diethyl ether, acetone, hexane, ethanol). The primary fire hazard is the flammable liquids being stirred.
-
Extinguishing Media: Use carbon dioxide (CO₂) or a dry chemical (ABC‑class) extinguisher for fires involving the electrical components or nearby flammable materials. Do not use water on electrical fires, as water conducts electricity and may cause electrical shock or damage the instrument.
-
Fire Response: In case of fire, immediately disconnect the instrument from its power source if safe to do so. Evacuate the immediate area. Use an appropriate fire extinguisher for small, contained fires. For larger fires, evacuate the laboratory and call emergency services. Do not attempt to extinguish a fire if not trained or if the fire is spreading rapidly.
-
Special Protective Equipment for Firefighters: Firefighters should wear self‑contained breathing apparatus (SCBA) and full structural firefighting gear when fighting fires in laboratory settings, as combustion products may include toxic fumes from burning plastics and chemicals.
