Study Notes

Laboratory Safety Guidelines

Fill wash bottles exclusively with distilled water for rinsing glassware and equipment, or for adding water to containers.
Always grasp the plug when removing an electrical device from its socket; ensure hands are dry before touching any electrical components.
Inspect glassware prior to each use, avoiding any with chips, cracks, or dirt to prevent contamination or injury.
Report any damaged electrical equipment, including frayed cords or exposed wires, immediately to ensure safety.

Pipetting and Chemical Handling

Never use mouth suction to fill a pipet; instead, utilize a rubber bulb or pipet pump for safety.
When transferring reagents, keep containers at a distance from your body to minimize exposure to spills.
Handle acids with caution; always add acid to water, gently swirl the mixture, and be aware of heat production, especially with sulfuric acid.
Perform all work with flammable liquids over a pan to catch spills; avoid using flammable liquids near open flames or heat sources.

Chemical Transport and Glassware Management

Do not remove chemicals or materials from the laboratory area to maintain safety and compliance.
Exercise caution when carrying acids or chemicals within the lab; hold them securely and navigate carefully.
Carry glass tubing upright to reduce the risk of breakage and associated injuries.
Use a brush and dustpan to handle broken glass; dispose of it in designated glass waste containers to prevent cuts or injuries.
