The new Hazard Communication Standards provide teachers and students the right to __________ chemical hazards.
Aleonysh [2.5K]

The new Hazard Communication Standards provide teachers and students the right to manipulate chemical hazards.

Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, <u>employees are exposed to them and are vulnerable to harm from these chemicals</u>.  

There are many types of hazardous chemicals to be wary of, such as:

  • Carcinogens
  • Neurotoxins
  • Acids
  • Systemic toxins
  • Asmogens
  • Silica dust
  • Lead

In the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.

The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. <u>This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies</u>, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.

Therefore, by having these safety standards in place in schools and universities, teachers and students have the possibility and the right to handle chemical hazards safely to be able to conduct the class normally and learn what is necessary.

Chloramphenicol binds in the active site of the large ribosomal subunit and inhibits peptidyl transferase activity in the 23s rr
valentina_108 [34]
This inhibition is restricted to bacterial translation because; the peptidyl transferase is an enzyme aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the process of translation. Therefore, inhibition of this enzyme means that the process oof translation wont take place, hence proteins will not be formed and thus the bacteria will die.
