PRODUCTION OF ELECTROMAGNETIC RADIATION

Monday, February 22nd, 2010

electromagnetic radiationThe easiest and most commonly used to produce microwave radiation, is one who is to pass through the high frequency currents. It was the method used by Hertz in his famous experiments and the method is still used today in all transmitters.

In the minds of many technicians, radiation and high frequency power became synonymous. However, this view is not permissible and the thing seems obvious to some one wants to think it over.

The current high frequency radiation is no longer a current phone is a sound vibration. To move from one state to another, you must use a power transformer which is in the first case, a radiator or wave transmitting antenna, and in the second case, a loudspeaker.

An electrical circuit may be the site of a current high-frequency intense without any trace of radiation. It is therefore interesting to try to understand how we can move from a current high-frequency energy radiated.

Hazards and Controls Safety Hazards at Work

Friday, February 5th, 2010

aNot only a reference to salary in determining the type of work.

Safety is something that should be a priority.

What does this mean a big salary, if security is not pawned? Is not no benefit if threatened life or health?

You need to know the two most important things that cause accidents, including:

* Behavior that is unsafe
* The environmental conditions are not safe

However, according to the Office of Human Resources Training, the cause of the accident, never because of the safety of workers was both dangerous behavior by the influence of the following factors:

1. Frivolous and not the heart – heart
2. Not eligible
3. No regular work processes
4. Do not use protective clothing
5. The condition of weak entity

The proportion of accidents with 3% due to the cause can not be avoided, such as natural disasters, for example. Other factors that interfere with the security of 24% due to the work environment or equipment which are not refundable and 73% due to dangerous behavior.

Of course, the most effective means to prevent accidents is the occurrence of five types of dangerous behavior to avoid the already mentioned. Therefore, appropriate measures against child labor and equipment should ensure that workers have the concept of health and safety to prevent accidents.

If so, is the training of health and safety is very important. The aim, among other things, protect the health of workers, improve conditions, efficiency, avoiding the occurrence of accidents and occupational diseases. According to various safety and health at work:

1. In anticipation of the existence of factors that affect risk and that appropriate arrangements.
2. Understanding the types of workplace hazards
3. Assessing the level of risk in the workplace
4. In the presence of danger or complications.

They relate to safety, hazardous factors, including the most common:

1. The types of chemical hazards: inhalation or skin contact between the liquid metal, non-liquid metals, hydrocarbons and ash, gas, steam, steam, smoke and toxic Dew.

2. Dangers of physics: the temperature of the hot and not cold and radiant environment of ionizing radiation, noise, vibration and air pressure is not normal.

3. The man, because the risk of the project: lighting and lamps, which provide a lower risk of transportation and the threat of plant reaction.

What, how, to take the threat of health hazards under control:

1. Control Engineering: to isolate the changes in work procedures, and concluded with hazardous substances, the use of automation to work with operational changes and ventilation of moist air.

2.Administrative Control: Reducing the exposure time, make arrangements to pay the health and safety regulations, personal protective equipment, installing warning signs, make a list of content data is safe in making the emergency management system training.

Based on work and Welfare Act of accidents, employers on the principles of the workload, workers should help solicit participation in the labor insurance, to ensure safety.

Furthermore, after an accident, the owner should be subsidies for the accident. If the business does not comply with the registration of workers involved safe work under the Employment Act, employers have to pay a fine.

Infrared and ultraviolet radiation

Saturday, December 26th, 2009

Infrared Radiation or Thermal: These rays are visible but its wavelength falls between 8,000 Angstroms and 0.3 mm. A body subjected to heat (over 500 ° C) emits heat radiation, which can be made visible when the body temperature is high enough. We must point out that these rays are not the only producers of caloric effects. We know that the hot bodies emit infrared up, but all radiation can be transformed into heat when absorbed. (more…)

Occupational Pollutants

PollutantsIndustrial Hygiene would be “discipline is responsible for identifying, evaluating and controlling occupational pollutants.

There are three types of pollutants:

  1. Physical Contaminants.
  2. Chemical Pollutants.
  3. Biological Pollutants.

Industrial hygiene is primarily focused on physical and chemical contaminants, while biological contaminants enter the medical field.

Chemical pollutants may occur in the following states:

  1. Solids:
  2. Dust (silica).
  3. Fibers (asbestos).
  4. Smoke (fuel).
  5. Liquids: Aerosols (pesticides).
  6. Gaseous vapors (solvents).
