SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Magnetic Field Interference: The stirrer contains strong permanent neodymium magnets. People with implanted medical devices (e.g., pacemakers, neurostimulators, implantable cardioverter‑defibrillators) should keep a safe distance of at least 30 cm from the operating stirrer. Do not place the instrument near credit cards, hard drives, computer monitors, or other magnetic‑sensitive equipment.
Vessel and Stir Bar Selection: Use only flat‑bottomed vessels (beakers, Erlenmeyer flasks, crystallising dishes) that sit flush on the ceramic‑coated work plate. Ensure each vessel is properly centred over the magnetic drive coil. Select stir bars in good condition without chips, cracks, or deformities. Do not exceed the maximum stir bar length (80 mm).
Start Slowly: Always start stirring at the lowest speed (just above “0” on the dial) and gradually increase to the desired speed. A sudden high‑speed start may cause the stir bar to decouple, spin erratically, and strike the vessel wall, causing splashing, spillage, or vessel breakage.
Electrical Safety: Do not operate the instrument with wet hands. Ensure the mains power cable does not come into contact with liquids or sharp edges that could damage the insulation. Use only the supplied grounded power cord and ensure the outlet provides proper grounding. Do not operate if the power cord is damaged.
Operating Environment: The MS‑S is designed for indoor laboratory use only. Do not use the instrument in explosive atmospheres, in the presence of flammable gases or vapours, or in environments where condensation is likely to occur. The permissible ambient temperature range is 5–40 °C with relative humidity not exceeding 80 %. Place the instrument on a stable, level benchtop with at least 5 cm clearance on all sides for ventilation. Do not cover the instrument during operation.
Spill Management: If a liquid spill occurs on the work plate during operation, turn off the speed immediately to “0”. After the spill has been wiped clean and the work plate is completely dry, resume operation. Prolonged contact with aggressive solvents (e.g., acetone, chlorinated solvents) may damage the ceramic coating. Do not pour solvents directly onto the work plate.
Cleaning and Maintenance: Unplug the instrument before cleaning. Wipe the ceramic‑coated work plate and the outer housing with a soft, slightly damp cloth using a mild laboratory detergent or 70 % isopropyl alcohol. Do not immerse the unit in liquid. Do not use abrasive cleaners, metal scouring pads, or sharp objects that could scratch the ceramic coating. Allow the work plate to dry thoroughly before reconnecting power.
Multi‑Vessel Use: When stirring multiple vessels (if the work plate is large enough), ensure they are positioned at least 1 cm apart to prevent magnetic interference and accidental collisions. Do not stack or overload the work plate with vessels that exceed its load capacity.
Training Requirement: Only trained laboratory personnel with appropriate technical background in laboratory equipment operation should operate the MS‑S for clinical diagnostic or research applications. Users must read and understand the operator’s manual before first use. Laboratory managers should ensure that all operators are aware of the proper procedure for starting and stopping the stir bar.

2. 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. 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 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 lacerates the skin, allow the wound to bleed freely. 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.
Inhalation of Chemical Vapors: If vapours from volatile reagents are inhaled during sample preparation, move the affected person to fresh air immediately. Administer oxygen if breathing is difficult. Seek medical attention if coughing, dizziness, or respiratory distress persists.
Electrical Shock: If an electrical shock incident occurs, disconnect power at the circuit breaker or unplug the instrument before attempting to assist the victim. Do not touch the victim until the power is disconnected. Call emergency medical services immediately.

3. FIRE FIGHTING MEASURES

Flammability: The instrument’s metal housing is non‑combustible, but the plastic control panel, power cord, and electronic components are combustible. Do not operate near flammable solvents, gases, or volatile materials (e.g., diethyl ether, acetone, hexane). 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. Do not use water, as water conducts electricity and may cause electrical shock or damage the instrument.
Fire Response: In case of fire, disconnect the instrument from its power source if safe to do so. Evacuate the immediate area. Use an appropriate 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.

Storage: Store the instrument in a clean, dry, dust‑free environment at room temperature (15–30 °C) when not in use. Keep the work plate covered to prevent dust accumulation. The IP42 rating provides protection against dust ingress during storage.

Multi‑Vessel Use: When stirring multiple vessels (if the work plate is large enough), ensure they are positioned at least 1 cm apart to prevent magnetic interference and accidental collisions. Do not stack or overload the work plate with vessels that exceed its load capacity.

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. 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 or signs of chemical burn develop, seek medical evaluation. Refer to the Safety Data Sheet (SDS) for the specific chemical involved.
