Biohazard Enter Body & Level Of Bh (1).docx

Biological hazards can enter the body in many ways. Biological hazards enter the body through inhalation, absorption, ingestion and injection.

The most common route biohazard get into the body is by Inhalation . The effect on the body depends on the biohazard and the amount that is breathed in. Although our body filters many of the normal pollutants from the air we breathe, it cannot eliminate every type of contaminant. Small particles are difficult to eliminate and can get deep into the lungs where they can cause respiratory problems. It is important to notice warning signs, such as smelling chemicals odour.

Second route is absorption which our skin is a major route of entry for hazardous substance.A biohazard can enter the bloodstream through broken skin, such as a cut,and chapped skin. Exposure to chemicals, biological hazards in the workplace can result in occupational diseases and allergic reactions.

Third route is ingestion.Some ingested hazardous agents are neutralized in the stomach, while others are absorbed into the bloodstream and transported to target organs.Important methods of prevention are personal hygiene and ensure food storage and eating areas are away from work areas.Swallowing bio-hazards can sometimes occur without us knowing it, often simply from not washing our hands.

The last route is injection, When something sharp punctures the skin, a biohazard can enter the body through the skin. At home, if we drop a glass on the floor, what will we do? Sweep up the pieces with a broom? Pick them up with our bare hands? In a lab if that glass contained a biohazard, picking the pieces up with our bare hands could enable the biological agent to enter the body through the cut or puncture.

There are four different levels of biological hazards.

Level One of biological hazards is usually bacteria of other types of microorganisms that are relatively harmless to a human and environment. The best way to protect you from this level of hazards is to wear PPE and wash hand frequently. The most common level one biological hazard is canine hepatitis and non-infectious bacteria.

Level Two biological hazards are moderate potential hazard to personnel and the environment. Includes bacteria and viruses that cause mild disease,such as influenza A, Hepatitis A,B and C.

Level Three can have severe or even fatal symptoms in humans but can usually treat by vaccines or other treatments that know exist.They can cause serious or potentially lethal disease through respiratory transmission such as H1N1 Flue, HIV,SARS and Rabies.

Level Four is by far the worst types of biological hazards. They can cause severe illness or death in humans and have no known vacations or treatments. The most deadly of these biological hazards are Ebola, bird flu, Bolivian, and Dengue fever.
