Label supervisor

A copy of the label to be used is generally attached to the documents, to allow the supervisor and operators to verify easily that the correct label has been dispensed for the product in question. 

The instructor or laboratory supervisor will provide the student with the proper procedure and the location where waste is to be placed (usually a separate labeled container in a hood). 

Students, workers, supervisors, managers, and administration should comply with the chemical safety management group/team. This is applicable to laboratories, university departments, factories, and industrial units where exposure to chemical substances is likely and precautions are necessary. People should be fully informed of the hazards involved and trained in appropriate safe working practices, globally harmonized system (GHS) for classification and labeling of chemicals, and first-aid measures. 

Figures 2.6A and B. In Figure A the supervisor points ont important information on the label. Worker in Fignre B reads the label for prodnct use instruction prior to applying product with the air-blast sprayer. 

What labelled compound will you use Radioactive isotopes must be ordered well in advance through your department s Radiation Protection Supervisor. Aspects that need to be considered include ... 

Each new experiment should be planned carefully and experimental protocols laid down in advance so you work as safely as possible and do not waste expensive radioactively labelled compounds. In conjunction with your supervisor, decide whether your method of application will introduce enough radioactivity into the system, how you wiU account for any loss of radioactivity during recovery of the isotope and whether there will be enough activity to count at the end. You should be able to predict approximately the... 

Your supervisor has identified three balances for your use in this exercise and has labeled them A , B , and C . Using gloves to avoid fingerprints, measure the mass of a dry 25-mL beaker on each of these balances. Record these masses in your Data section and label clearly. 

Perform this test with the help of your supervisor. Place 1 drop of the solution labeled N03 in a cuvette. Add 1 drop of 0.1 M HC1 and fill to the top with distilled water. Shake. Nitrate strongly absorbs ultraviolet light at 220 nanometers (nm) under these conditions. Wipe the exterior of the cuvette with a paper towel, and place it in an ultraviolet (U V) spectrophotometer set at 220 nm. A high absorbance reading represents a positive test for nitrate. Compare with distilled water. 

The reference sources to be used are the Handbook of Chemistry and Physics (published by CRC Press LLC) the Merck Index CD-ROM (published by Chapman and Hall) the Material Safety Data Sheet (MSDS) found in the lab or on the Internet, such as through the Fisher Chemical Company Web site (www.fisherl.com), or others suggested by your supervisor the labels on the stock containers of the chemicals found in the laboratory and the Fisher Chemical Company chemicals catalog. Your supervisor will demonstrate the use of each of these. Your supervisor may or may not require you to use your laboratory notebook for this work. Accordingly, a data sheet is provided. 

I have provided your supervisors with copies of a document on MSDSs that should be very helpful as you proceed in this work. It is a section entitled Exploring MSDSs found in the book Building Student Safety Habits for the Workplace, published by Terrific Science Press at the Center for Chemical Education at Miami University, Middletown, OH. This section includes a set of instructions for doing exactly what is required for this project (Exercise 3B). I also have made photocopies of the labels in question (found in Section 2B in the above referenced book) and the MSDSs (found in Section 3B in the above referenced book). Also, your supervisors will decide who should evaluate which labels. I have recommended that each participant be assigned two of the four chemicals (four labels) at random, meaning that each participant will each have four labels to evaluate, a consumer product label and an industrial chemical product label for one chemical and a consumer product label and industrial chemical product label for a second chemical. Please use the method suggested for Exercise 3B in the book referenced above and keep a good record of your work in your notebook so that you can prepare a quality report memo for WSHA. 

Next, remove the zinc coating by reaction with a solution of hydrochloric acid (HC1) that is labeled 6 M HC1. In a fume hood, fill a container of appropriate size with the acid to a level that will cover the entire sample of steel (Caution Avoid Skin Contact). Your supervisor may suggest an appropriate container. Using tweezers or tongs to handle the steel sample, carefully immerse the sample in the acid. Avoid splashing of the acid. The reaction that takes place is...

Molly Kule was a lab technician who was asked by her supervisor to add names to the labels on a collection of alkenes that showed only structures on the labels. How many did Molly get right Correct the incorrect names. 

It is best to first obtain input from plant and shift supervisors as to which items need removing (and how soon) and which items (e.g., some labeling) constitute a beneficial addition to the plant. Any items to be retained (e.g., instruments) should be discussed with the department supplying them. The rest should be immediately removed. 

If you are not sure what the label is telling you, do not use the chemical until your questions are answered. Check the SDS or ask your supervisor for help. 

If there are containers which are not labeled, or with labels that you cannot read or that are torn or partially missing, report it to your supervisor immediately. 

A. The site supervisor will be responsible for ensnring that all containers entering the workplace are properly labeled. 

B. Each employee or supervisor shall be responsible for ensuring that all portable containers used in their work area are labeled with the appropriate material identity and hazard... 

Like an3dhing, labels wear out. They become soiled or unreadable, or they fall off". When you see this happen, let your supervisor know (so he/she can replace the label) and get instructions for using the chemical. 

The NIOSH label serves several purposes. It ensures selection of appropriate filters for the contaminants encountered in the workplace and permits the employee using the respirator to check and confirm that the respirator has the appropriate filters before the respirator is used. Color coding and labeling allow fellow employees, supervisors, and the respirator program administrator to readily determine that the employee is using the appropriate filters.
