Safety During Lab

If there is a chemical spill, notify your instructor immediately to prevent any further damage.

Gloves are also very important as your hands will be dealing with the hydrochloric acid. Hydrochloric acid is a strong corrosive acid, an acid-resistant lab coat, and face mask or protective

In 2005, a chemistry teaching lab accident at Texas Tech left three undergraduate students and one graduate teaching assistant injured after a waste bottle exploded. While a student had opened the container to pour waste inside, the glass bottle exploded due to an incompatible mixture of chemicals inside. This mixture was composed of an inorganic acid and an organic solvent. The written directions for the experiment failed to omit a step which used a nitric acid wash, despite having removing that part of the procedure years prior. After the explosion, the lab was evacuated and the Texas Tech Police Department and Lubbock Fire Department responded. Fortunately, all students and staff were wearing the proper protective garments (lab coats, goggles,

Safety glasses- protective eye wear must be worn since swarf and coolant is travelling and can be flying in any direction.

Eye protection; such as spectacle/goggles to prevent dust or any other harmful substances from your eyes.

Store dangerous, unpredictable chemicals in a flame resistant bureau or if non-combustible, or if in little sums, in a fume cupboard.

Before conducting the Activity Series Lab, participants must know how to protect themselves against the possible dangers that the hazardous materials from the lab can cause. Some of the things they must understand include proper safety precautions and how to protect against corrosive or poisonous materials. For instance, Copper (II) Chloride, one of the solutions used in the lab, can cause severe eye irritation. One way to protect against this is by wearing goggles, or other eye protection equipment. Another substance used in the lab is Silver Nitrate, a body tissue irritant. Participants must wash off the substance quickly if it comes into contact with their skin to prevent any serious damage. Not only is it vital to know how to be safe around the chemicals, but to fully understand the lab, participants must be able to recognize the clues to a chemical change.

A strategy that can be implemented is for example if a wet beaker were fall and break it’s best not to touch the broken shards and to call for the teacher’s assistance. I believe that I was able handle any kind of safety concerns in this practical fairly well. To ensure that no breakage occurred I carefully handled the beakers and test tubes by drying immediately after washing and placing them as far as possible from the edge of the

(i). Working with chemicals, or other experiments, always wear safety goggles/eye production , to prevent chemicals/glass from going in your eye.

Dispose and clean up the contents of your test tubes and put away all of your materials. Clean up your work station and hands.

Care should be taken when handling beakers, graduated cylinders, and any other glassware. It is also important to make sure beakers and graduated cylinders are not slippery, to prevent accidents. Since hydrochloric acid is harmful, even at low concentrations, glasses must be worn when using and handling it. Crystal violet also stains, so to avoid getting it on skin and clothing, gloves and an apron can be used if desired. Also be careful when pouring or using any of the chemicals, because they can cause irritation and can be harmful to skin and eyes.

The main hazard of this investigation is the methylene blue as it poses the risk of skin irritation and staining. To minimise this risk is to avoid contact with skin. If contact does happen to occur, the affected area should be run under cold water for at least 10 minutes.

A fire extinguisher should be used only if the fire is small and you are trained in its use.

As the experiment was using an acid, there had to be certain precautions taken when handling and pouring out the acid. Running water was readily available in case of skin contact. Lab coats were also worn so that clothes were not damaged. As the experiment was based around heat, gloves also helped in handling hot cylinders which reached high temperature. Running water was also available in case of a skin burn.

The High School is overrun with zombies. I have no where to turn. My best friends have joined the dead. I am lost, I have no one watching my back and I am stuck in the science labs. I have deiced to hide in the science labs because there are chemicals there that I know I can make something flammable to clear a path so I can get home to my family who is currently camping out at my girlfriends house. I was able to bring a total of 5 things in my back-pack to help keep me alive. I packed water in my bottle from the filtered faucet, butane from the storage of the lab, a flint striker for the butane, broken glassware that I can use for striking and potential kill some zombies and last but not least the heated safety blanket to keep me warm if
