4. Lab report information
Lab report is due at the beginning of the next class (for example, Lab #2
report is due at the beginning of Lab #3 class). 5. Lab safety
Safety precautions must always be taken during lab sessions. Failure to follow
the safety guidelines will result in your dismissal from the lab. A. Clothing
• Wear proper clothing. Proper protective clothing must be worn by all
persons in the room at all times that anyone is working with,
transporting glassware, or conducting any experimental work. Exposed lOMoAR cPSD| 23136115
chemical to the skin is susceptible to injury by splattering hot, caustic,
or flammable materials. Students and instructors must be protected from
their necks down below their knees. This requirement includes no
shorts, no short skirts, no sleeveless garments, no bralettes, and no bare
midriffs. Long lab coats are required if shorts or short skirts are worn.
Tightfitting clothing, long unrestrained hair, clothing containing
excessive fringe, or even overly loose-fitting clothing may be
considered unsafe. Long hair must be tied back, and no dangling jewelry.
• Wear proper protective footwear. No sandals/flip-flops/crocs, no
open-toed shoes, and no foot covering with absorbent soles are allowed.
Any foot protection that exposes any part of one’s toes is unsuitable for wear in the laboratory.
• Wear personal protective equipment. Very minor laboratory
accidents, such as the splattering of the solution, can cause permanent
eye damage, skin burnt, or acute burns of the respiratory system.
Wearing personal protective equipment (PPE), including gloves,
goggles, and respirators, can protect laboratory workers, and students,
and prevent the majority of laboratory accidents. PPE is not required in
all cases. Course instructors and the teaching team will decide when
wearing PPE is essential for a particular laboratory section.
B. Handling chemicals, glassware and equipments
• Only perform experiments under the supervision of an instructor or TAs.
• Always handle chemicals with experiment gloves to prevent direct
exposure of chemicals onto skin, chemical contamination, or injuries
due to glassware breakage. Wear further insulated gloves when handling hot and cold glassware. lOMoAR cPSD| 23136115
• Beware of using any kind of acid, base and other concentrated reagents.
Never heat a liquid in a test tube that is pointed toward you or another student.
• Never inhale gases or vapors unless directed to do so. If you must inhale
the odor of a gas or vapor, use your hand to waft a small sample toward
your nose. Never taste chemicals or perform pipetting by mouth, always
use a mechanical suction device such as graduated pipettes or micropipettes.
• Never return residual chemicals to their original containers since used
chemicals might contaminate original chemical. Used chemicals or
broken glassware should be disposed appropriately according to the
instruction of TAs. Report cuts, spills and other problems to the TAs or lab managers.
• Do not use or move any instruments in the lab unless directed to do so.
Before using read the equipment manual carefully. C. Behaviors
• Performing unauthorized experiments is forbidden.
• Never use an unknown or unmarked reagent. Do not drink, eat, smoke
in the lab area. Lab materials, chemicals and any equipment should
never be taken from the laboratory.
• All forms of pranks are never acceptable in the laboratory.
• Prepare notebook and pen/pencils for experiment recording. Phones,
laptop and other electronic devices are not allowed unless directed to use.
• Wash hands with soap after performing all experiments. Clean/ rinse
work surfaces and used equipment at the end of the experiment. lOMoAR cPSD| 23136115
D. Emergency procedures
If you experience a medical emergency, immediately inform the lab
manager, teaching assistant, and seek medical attention. Listed below are
first aid guides for situations that may occur in the lab.
• Heat burns: Wash the wound with cold water and cover with a clean bandage.
• Cold burns: Wash the wound with warm water and cover with a clean bandage.
• Cut & scrape: Wash the wound under a flowing faucet until it stops
bleeding. Sterilize with ethanol 90o and cover with bandage.
• Bleeding: If bleeding does not stop, apply pressure with a clean bandage
or cloth over the wound until the bleeding stops. Further seek immediate
medical help if bleeding remains.
• Eye injuries: Remove contact lenses, flush out eyes with cold water for at least 15 minutes.
• Poisoning: If the person is still conscious, ask them to sit still while
waiting for medical help to arrive. If poison was ingested, spit out if
possible. If poison was splashed on the skin or clothes, remove
contaminated items, and wash the contaminated area with water - be
careful not to contaminate yourself.
• Electric shock: Shut off electric power, remove the victim from electric
power, call the ambulance, perform CPR if no pulse and breathing is detected.
