Departments must set out and implement a basic level of control for those who may be exposed to chemicals, biological agents and ionising radiation. In each laboratory where there is a risk of exposure, safety rules must be drawn up and clearly displayed for workers to see.
only authorised persons may enter and/or work in the laboratory laboratory coats must be worn all required personal protective equipment must be worn sensible footwear must be worn eg no open sandals eating, drinking, smoking, taking medication, mouth pipetting and applying make-up is forbidden no storing of food or drink for human consumption is allowed all work must be carried out in accordance with risk assessment all waste must be disposed of in accordance with University policy all accidents and dangerous occurrences must be reported and recorded on the University’s Incident Reporting and Investigation System (IRIS),
Specific safety rules for chemistry laboratories can be found in the policy document S3/01 below. University policy on ionising radiation and biological safety outline additional controls, including the use of eye protection within containment laboratories.
Why are lab rules important?
Chemical safety rules – Since almost every lab uses chemicals of some sort, chemical safety rules are a must. Following these policies helps employees avoid spills and other accidents, as well as damage to the environment outside of the lab. These rules also set a clear procedure for employees to follow in the event that a spill does occur, in order to ensure it is cleaned up properly and injuries are avoided.
Every chemical should be treated as though it were dangerous.
Do not allow any solvent to come into contact with your skin.
All chemicals should always be clearly labeled with the name of the substance, its concentration, the date it was received, and the name of the person responsible for it.
Before removing any of the contents from a chemical bottle, read the label twice.
Never take more chemicals from a bottle than you need for your work.
Do not put unused chemicals back into their original container.
Chemicals or other materials should never be taken out of the laboratory.
Chemicals should never be mixed in sink drains.
Flammable and volatile chemicals should only be used in a fume hood.
If a chemical spill occurs, clean it up right away.
Ensure that all chemical waste is disposed of properly.
What are the 7 steps of lab report?
Writing lab reports follows a straightforward and structured procedure. It is important to recognize that each part of a lab report is important, so take the time to complete each carefully. A lab report is broken down into eight sections: title, abstract, introduction, methods and materials, results, discussion, conclusion, and references. Title
The title of the lab report should be descriptive of the experiment and reflect what the experiment analyzed.
Ex: “Determining the Free Chlorine Content of Pool Water”
Abstracts are a summary of the experiment as a whole and should familiarize the reader with the purpose of the research. Abstracts will always be written last, even though they are the first paragraph of a lab report. Not all lab reports will require an abstract. However, they are often included in upper-level lab reports and should be studied carefully. When writing an abstract, try to answer these questions:
Why was the research done or experiment conducted? What problem is being addressed? What results were found? What are the meaning of the results? How is the problem better understood now than before, if at all?
The introduction of a lab report discusses the problem being studied and other theory that is relevant to understanding the findings. The hypothesis of the experiment and the motivation for the research are stated in this section. Write the introduction in your own words. Try not to copy from a lab manual or other guidelines. Instead, show comprehension of the experiment by briefly explaining the problem.
Methods and Materials
The methods and materials section provides an overview of any equipment, apparatus, or other substances used in the experiment, as well as the steps taken during the experiment. If using any specific amounts of materials, make sure the amount is listed.
Ex: pipette, graduated cylinder, 1.13mg of Na, 0.67mg Ag
List the steps taken as they actually happened during the experiment, not as they were supposed to happen. If written correctly, another researcher should be able to duplicate the experiment and get the same or very similar results.
The results show the data that was collected or found during the experiment. Explain in words the data that was collected. If using graphs, charts, or other figures, present them in the results section of the lab report.
Tables should be labeled numerically, as “Table 1”, “Table 2”, etc. Other figures should be labeled numerically as “Figure 1”, “Figure 2”, etc.
Calculations to understand the data can also be presented in the results.
The discussion section is one of the most important parts of the lab report. It analyzes the results of the experiment and is a discussion of the data. If any results are unexpected, explain why they are unexpected and how they did or did not effect the data obtained. Analyze the strengths and weaknesses of the design of the experiment and compare your results to other similar experiments. If there are any experimental errors, analyze them. Explain your results and discuss them using relevant terms and theories. When writing a discussion, try to answer these questions:
What do the results indicate? What is the significance of the results? Are there any gaps in knowledge? Are there any new questions that have been raised?
The conclusion is a summation of the experiment. It should clearly and concisely state what was learned and its importance. If there is future work that needs to be done, it can be explained in the conclusion.
If using any outside sources to support a claim or explain background information, those sources must be cited in the references section of the lab report. In the event that no outside sources are used, the references section may be left out.
What to do before a lab?
Will I need to take other steps to prepare for my lab test? – For many lab tests, you don’t need to do anything other than answer questions from your provider and/or lab professional. But for others, you may need do some specific preparations before the test.
- One of the most common lab test preparations is fasting,
- Fasting means you should not eat or drink anything except water for up to several hours or overnight before your test.
- This is done because nutrients and ingredients in food are absorbed in the bloodstream.
- This can affect certain blood test results.
The length of fasting can vary. So if you do need to fast, make sure you ask your provider how long you should do it. Other common test preparations include:
- Avoiding specific foods and drinks such as cooked meats, herbal tea, or alcohol
- Making sure not to overeat the day before a test
- Not smoking
- Avoiding specific behaviors such as strenuous exercise or sexual activity
- Avoiding certain medicines and/or supplements. Be sure to talk to your provider about what you are currently taking, including over-the-counter medicines, vitamins, and supplements.
For some blood tests, you may be asked to drink extra water to help keep more fluid in your veins. You may also be asked to drink water 15 to 20 minutes before certain urine tests.
What are the three major types of laboratory hazards?
Different types of hazards – An important first step in protecting worker health and safety is recognizing workplace hazards. Most hazards encountered fall into three main categories: chemical, biological, or physical. Cleaning agents and disinfectants, drugs, anesthetic gases, solvents, paints, and compressed gases are examples of chemical hazards.
- Potential exposures to chemical hazards can occur both during use and with poor storage.
- Biological hazards include potential exposures to allergens, infectious zoonotics (animal diseases transmissible to humans), and experimental agents such as viral vectors.
- Allergens, ubiquitous in animal research facilities, are one of the most important health hazards, yet they are frequently overlooked.
The final category contains the associated with research facilities. The most obvious are slips and falls from working in wet locations and the ergonomic hazards of lifting, pushing, pulling, and repetitive tasks. Other physical hazards often unnoticed are electrical, mechanical, acoustic, or thermal in nature.
What is the most important science rule?
The Most Important Lab Safety Rule – Portra / Getty Images Follow the instructions ! Whether it’s listening to your instructor or lab supervisor or following a procedure in a book, it’s critical to listen, pay attention, and be familiar with all the steps, from start to finish, before you begin.
You endanger yourself and others in the lab. You could easily ruin your experiment. You put the lab at risk of an accident, which could damage equipment as well as harm people. You could get suspended (if you’re a student) or fired (if you’re a researcher).
