How is air disinfection achieved in practice?

In practice, air disinfection is achieved through ventilation. However, this needs to be supported by other controls. The high-efficiency particulate air filter (HEPA) is quite helpful in achieving this. HEPA works in the central ventilation ducts by disrupting droplet nuclei recirculation. The Ultraviolet Germicidal Irradiation UVGI is used because noise,...

Describe the process of correctly entering confined space of unknown risk.

This depends on whether one is using vertical or horizontal entry. For vertical entry, one should start from the external area prior to opening the actual confined space. Monitoring of this space is necessary. Then one should open the entry hole and place the probe in it. Monitoring should commence...

What are some of the control methods used for indoor air quality problems?

These figures represent: dBA=this is the effective sound level at the employee’s ear when using the device. It is A-weighted dBC=This...

What are some of the difficulties associated with the use of hearing protectors?

Hearing devices may come in the form of earplugs or earmuffs. When using ear muffs, workers may break the seal using their spectacle frames, caps or even their hair. Earmuffs cause discomfort in hot weather. They are not appropriate for use with caps or other headgear and are uncomfortable in...

What factors are important in the selection of eye protectors?

When choosing eye protectors, one must consider the risk that the eye faces and the employees’ eyesight; this case requires prescribed protectors. Also, workers’ conditions are important; the visual requirements of the tasks need to be considered. Workers’ tastes should be considered as some are selective about the comfort and...

Explain the importance of the direction of airflow.

Employees need to be protected from exposure to contaminants within their breathing zone. The direction of airflow, therefore, ascertains that this contaminated air is removed from the breathing zone. The direction of airflow helps in carrying fresh air away from workers so as to pick up the contaminants and take...

Why is duct velocity important?

Duct velocity is crucial in preventing contaminants from settling in the duct. This works by transporting those contaminants through the air stream in the duct. It should be noted that when contaminants settle in this region, they can affect the ventilation system by blocking it. If they continue settling there,...

Why is capture velocity important?

Capture velocity is understood as the air velocity that overcomes opposing air currents by containing contaminated air and causing it to get into a hood. This air velocity must be near the source of contaminants. Workers should be protected from exposure to contaminants through the capture velocity as all the...

Describe the effect of a containment feature in a local exhaust ventilation system.

A containment feature in a local exhaust ventilation system works by protecting workers from exposure to volatile and toxic substances in their breathing zones. When capturing contaminated air, one will not require too much volume in order to achieve this goal. The contaminated air is contained in a limited room....

What are the primary reasons for inadequate local exhaust ventilation system performance?

Poor designs are the major cause of inadequate local exhaust ventilation performance. When many workplaces are in the construction phase, their constructors rarely think about ventilation systems. This means that when they are finally put in place, they may end up not receiving the attention they deserve; the systems eventually...

Compare the environmental monitoring methods for exposure to heat. Which one is better?

Exposure to heat can be measured through various elements. Air movement, absolute humidity, mean radiant temperature and air temperature are just some of the components that can indicate the level of heat exposure. Through the use of exposure restriction and the latter mentioned measures, it is possible to protect workers...

What control measures should be used for workers in cold environments?

One can start with PPEs. They can be given ear muffs, cold masks or respirators. Administrative control can also be quite helpful. This may be done through the measurement of air movements, wind speed and temperature. It may also be achieved through medical checkups and task reassignment. Work should be...
