Engineering controls safeguard employees by eliminating dangerous situations or by erecting a barrier between the employee and the risk. Examples include machine guards to protect the worker or local exhaust ventilation to capture and remove airborne pollution.
What is the difference between engineering control and administrative control?
Engineering controls could involve altering the weight of the products, adjusting the heights of the work surfaces, or getting lifting equipment. Administrative controls are workplace policies, practices, and processes that reduce the likelihood of risky situations for employees.
What are the basic principles of engineering controls?
- Redesigning a process to use less dangerous chemicals;
- Redesigning a piece of equipment to eliminate the source of high temperatures, noise, or pressure;
- Designing general ventilation with enough fresh outdoor air to improve interior air quality and generally to provide a safe, healthy environment.
- Redesigning a workstation to reduce physical stress and remove ergonomic dangers.

Answer:
C) Stratified sampling
Explanation:
Stratified sampling: This is one of the probability sampling technique in which the researcher tends to divides a particular population that is taken for the researcher purpose into various groups or strata, and after dividing the population, the researcher randomly finally selects the participants from those groups or strata and being analyzed later on. Further, the group is taken for study is through the random sampling technique.
Advantage:
1. It provides great precision.
2. The study group is small, hence cost-effective.

Answer:
“The Model of Dual Federalism” that is characterized as the relationship in which tension and conflict between the Central State and the Particular States predominate and the ties of consensus and collaboration are weakened. Both centers of power are sovereign and equal "in their respective spheres", consequently they distinguish and distribute the powers that each one must perform.
In the "cooperative federalism model" the distribution of power and authority between the national, provincial and local levels are mixed, owing its name to Grodzins Morton, who describes it with the example of the health officer whose activities and functions do it simultaneously Federal state official of the county and also an official of the urban council. The Federal State appoints it according to the merit guidelines that it establishes, its salary comes jointly from federal and state resources, the county provides the office and the largest city in the county covers part of its expenses, such as maintaining the office . Your job is to inspect food, applying federal standards as well as state laws. This by way of illustrative data that does not exhaust the example, since it is richer, gives us the pattern that the authority overlaps, is shared, there being no exclusive competences in important matters that correspond to a single level. There is no clear division or division of powers, responsibilities are shared.
