SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

UV Radiation Hazard: The deuterium lamp emits UV radiation. Always keep the sample compartment cover closed during operation. Never stare directly at the light source
Electrical Safety: Do not operate with wet hands. Disconnect power before cleaning or performing lamp replacement. Use only the supplied power cord and ensure proper grounding
Hot Surface Hazard: Tungsten and deuterium lamps become extremely hot during operation. Allow lamps to cool for at least 30 minutes before handling or replacement
Chemical Hazard: Handle all reagents, standards, and patient samples according to laboratory safety protocols. Wear appropriate PPE including gloves and lab coat. Clean spills immediately to prevent damage to instrument optics
Cuvette Safety: Handle cuvettes with care; broken glass or quartz can cause injury. Dispose of broken cuvettes in sharps containers
Sample Containment: Ensure cuvettes are properly seated in the sample holder to prevent spillage. Use sealed cuvettes for volatile or hazardous samples
Stability Requirement: Allow 2-hour warm-up before critical measurements to achieve specified stability specifications
Training Requirement: Only trained laboratory personnel should operate the SP-UV1000 for clinical diagnostic applications

2. FIRST AID MEASURES

UV Exposure to Eyes: If the sample compartment cover is opened during operation and UV exposure is suspected, rest eyes and seek ophthalmologic evaluation if symptoms (pain, redness, photophobia) develop
Skin Contact with Hot Lamp: If burn occurs from contact with hot lamp, cool the area with cool running water for 15 minutes and seek medical attention for severe burns
Chemical Splash to Eyes: If chemical sample splashes into eyes during cuvette handling, flush immediately with water for 15 minutes and seek medical attention
Skin Contact with Chemical Sample: Wash contaminated skin with soap and water thoroughly; if irritation or signs of infection develop, seek medical evaluation
Sharps Injury: If broken cuvette glass punctures skin, wash wound thoroughly and follow facility's exposure management protocol for bloodborne pathogens if sample is biological
Electrical Shock: If electrical incident occurs, disconnect power immediately. Do not touch person until power is disconnected. Seek emergency medical attention

3. FIRE FIGHTING MEASURES

Flammability: The instrument's plastic housing and internal components are combustible. Lamps operate at high temperatures and can ignite flammable materials in close proximity
Extinguishing Media: Use carbon dioxide (CO₂) or dry chemical extinguisher for electrical fires. Do not use water on electrical fires
Fire Response: Primary fire hazard is flammable reagents or solvents being measured. Follow laboratory fire safety protocols. Disconnect power if safe to do so
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear when fighting fires in laboratory settings
