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.

Explanation:
Like carbon, nitrogen has its own biogeochemical cycle, circulating through the atmosphere, lithosphere, and hydrosphere (Figure 5). ... In this symbiotic association, the bacteria become encased in nodules that grow on the roots of plants, through which nitrogen that has been fixed by the resident bacteria is obtained.
Many disorders can be heritable through the generation. Knowing the patterns of disorder heredity, either it is dominant or recessive, autosomal or sex-linked is a great advantage in making a diagnose. It should be taken into consideration that some diseases can be influenced by environmental factors. For example, a person knows its parents had high blood pressure. That person has a predisposition for high blood pressure too. But, since heredity and family medical history is known, that person can prevent the appearance of the disease by taking care of its condition, performing physical activities, avoiding smoking, fat diet, etc.
