SBL 1023 - LABORATORY REPORT OF EXPERIMENT 1

EXPERIMENT 1 : LABORATORY SAFETY

  • Introduction
  In some laboratories, the conditions are no more dangerous than in any other room. Lab environments expose workers to numerous hazards including chemical, biological, physical and radioactive hazards. In laboratories where the dangerous conditions might exist, safety precautions are important. Rules exist to minimize the individual’s risk, and safety equipment is used to protect the lab user from injury or to assist in responding to an emergency. Lab equipment and chemicals that are improperly handled can result in personal injury and even death. Chemical spills, toxic fumes, needle pricks, and fires can harm lab workers and all the people either in or surrounding of the laboratory.

In this experiment, we will learn more detail about the safety rules in laboratory. Laboratory safety is including :

1) Laboratory safety procedure
2) Protective procedure
3) Emergency procedure
4) Chemical safety

  •  Objective
i. To make sure that all of the students are ready mentally and physically before enter the lab.
ii. To give students more knowledge and information about lab safety procedures.
iii. To make sure safety are priority until the end of the experiments.

  • Method


Laboratory safety procedures: 

a) Reporting all spills and broken glassware to the instructor and receiving instructions for clean up.
b) Washing hands prior to and following laboratories and at anytime contamination is suspected.
c) Disinfecting lab benches and equipment prior to and at the conclusion of each lab session, using an appropriate disinfectant, and allowing a suitable contact time.
d) Identification and proper disposal of different types of waste.
e) Reading and signing a laboratory safety arrangement indicating that the student has read and understands the safety rules of the laboratory.
f) Good lab practice, including returning materials to proper locations, proper care and handling of equipment, and keeping the bench top clear of extraneous materials. 

Protective procedures:

a) Wearing long pants or dresses (NO shorts, NO sandals).
b) Tying long hair back, wearing personal protective equipment (eye protection, coats, gloves; glasses may be preferred to contact lenses), and using such equipment in appropriate situations.
c) Always using appropriate pipetting devices and understanding that mouth pipetting is forbidden.
d) Never eating or drinking in the laboratory.

Emergency procedures:

a) Locating and properly using emergency equipment (eye wash stations, first aid kits, fire extinguishers, chemical safety showers, telephones and emergency numbers).
b) Reporting all injuries immediately to the instructor.
c) Following proper steps in the event of an emergency.

Chemical safety:

a) Treat every chemical as if it were hazardous.
b) Never "smell" a solvent!! Read the label on the solvent bottle to identify its contents.
c) Make sure all chemicals are clearly and currently labeled with the substance name, concentration, date, and name of the individual responsible.
d) Never return chemicals to reagent bottles. (Try for the correct amount and share any excess).
e) Close chemical bottle immediately after use.
f) Comply with fire regulations concerning storage quantities, types of approved containers and cabinets, proper labeling, etc. If uncertain about regulations, contact the building coordinator.
g) Use volatile and flammable compounds only in a fume hood. Procedures that produce aerosols should be performed in a hood to prevent inhalation of hazardous material.

h) 
Never allow a solvent to come in contact with your skin. Always use gloves.
i) Dispose of waste and broken glassware in proper containers.
j) Clean up spills immediately


  • Result
ACTIVITY 1

List the Protective Procedure in your lab. Attach pictures as proof.

List of protective procedure in lab
What error (if any) did you observed?


Wear glove when handling any chemicals.





Wear gloves, eye protection and other protective equipment in appropriate situations.


Always wear a suitable attire when entering the lab.


When entering the lab, we must always wear a suitable footwear.


Any food and drink are prohibited.


Dispose any types of waste according to the label.








ACTIVITY 2

Locate and list the Emergency Procedure in your lab. Attach pictures as proof.

List of emergency procedure in lab
What error (if any) did you observed?
Chemical safety shower and eye wash station. (the front area of the lab)

The chemical safety shower is not functioning due shower valve was broken.

Plan location in any case of emergency.
(Under the main switch)


Exit sign above each doors in the lab.


Emergency number that can be contact.
(attach on the window)


First aid kit ( at the back area of the lab)

ACTIVITY 3



Identify the hazardous level of 5 laboratory chemicals in your lab. Attach pictures as 
proof.

Laboratory chemicals
Hazardous level (NFPA Label,
Pictogram)

Ethyl Alcohol
 
Sulphuric acid



















Potassium permanganate




Sodium Hydroxide


Acetic acid


  • Discussion
What we have learnt in this laboratory safety is, we have to be more careful especially with the physical,biological and chemical hazards. We also need to know about laboratory safety procedures , protective procedures,emergency procedures and also chemical safety.
When we are in lab, we have to wear some laboratory safety,which is wear glove, wear foot protection , wear lab coat, wear goggles and also face mask.

  •    Conclusion




From the Experiment 1, students gain more knowledge about the safety rules that must be followed by all the students. There are 4 main protections such as laboratory safety procedures, protective procedures, emergency procedures and chemical safety. All of this protections are very important and student should be able to understand and obey all the rules to make sure their safety are always the priority.

For laboratory safety procedures, students learned about responsibility and action that must be taken when something bad happen in laboratory. We also learned about cleanliness to protect our body from any hazards that can be harmful for people.

Then, for protective procedures, students learned about all the rules before entering the laboratory. For example, student should wear gloves, goggles, lab coat and so on. Therefore, student also learned about the rules when the experiment is in progress. For example, students are advised to always using the appropriate tools for each experiment and never eating or drinking in the laboratory during the experiment.
In the same time, for emergency procedures, students learned about the proper steps that must have follow in the event of an emergency such as the location of emergency equipment  and their function. We also need to know the emergency number and the instructor for each laboratory.

    Lastly, for chemical safety, student learned about the functions, hazards and label on each chemical in laboratory and its prevention. Students also learned about how to use chemical the right way and the procedures that students should follow to be safe in laboratory.
