Assume that all reagents are poisonous and act accordingly. Read the labels on chemical bottles for safety precautions and know the nature of the chemical you are using. If chemicals come into contact with skin, wash immediately with water. DO NOT: Taste, smell or ingest chemicals or pipette anything by Eat, drink or smoke in the lab at any time!

Wear clothing that is extremely loose or tight Overly tight clothes, such as leggings and body suits, are not recommended, as any spilled material will be held next to the skin by these garments Wear overly loose clothing, long necklaces, ties, or scarves that can get caught in equipment or knock over work Loose clothing should be secured so they do not get caught in a flame or chemicals. Wear jewelry under disposable gloves or when working on Work with matches, lighted splints, Bunsen burners, when wearing acrylic nails.

Wear full coverage shoes that are non-skid and constructed of sturdy material must be worn at all times while in the lab as protection against broken glass or spillage that may not have been adequately cleaned No flip flops or sandals are permitted. Tie back long hair so it does not come in contact with fire, chemicals, biological or radiological substances or if there is a possibility of becoming entangled in Learn how to transport all materials and equipment Handle hot glassware with a test tube clamp or tongs. Use caution when using heat especially when heating chemicals. Do not leave a flame unattended; make certain gas Jets are off when the Bunsen burner is not in use. Use proper ventilation in hoods when instructed; Keep solids out of the Read chemical bottle labels; be aware of the hazards of all chemicals Know the safety precautions for each. Stopper all reagent bottles when not in use. Immediately wash reagents off yourself and your clothing and if there still on you, immediately inform the instructor. If you accidentally get any reagent in your mouth, rinse out with water thoroughly, and immediately inform you Use extra care and wear disposable gloves when working with glass tubing and when using dissection equipment scalpels, knives, or razor blades, when cutting or Administer first aid immediately to clean, sterilize, and cover any scrapes, cuts, and burns where the skin is broken and/or where there may be bleeding. Wear bandages over open skin Use caution during any outdoor activities. Watch for snakes, poisonous insects or spiders, stinging insects, poison oak, poison ivy, and so Be careful near water.
