bukan! bukan! logo ini bukan kelab atau persatuan baru.. tetapi logo hazard biologikal.
pernah nampak logo ini pada mana-mana bungkusan seperti ini???
pekerja di atas terlibat dengan aktiviti menganalisis pelbagai jenis spesimen biologi yang boleh mendedahkan diri beliau dijangkiti penyakit. tahap kebahayaan sesuatu spesimen juga tidak sama dan mengikut
i) sifat semulajadi dan kepekatan agen penyakit
ii) laluan masuk agen penyakit ke dalam badan
iii) ketahanan pekerja yang terdedah
According to OSHA,
Biological Hazard means a naturally occurring substance that can be harmful to employees.
A biological hazard or biohazard is an organism, or substance derived from an organism, that poses a threat to (primarily) human health. This can include medical waste or samples of a microorganism, virus or toxin (from a biological source) that can impact human health. It can also include substances harmful to animals. The term and its associated symbol is generally used as a warning, so that those potentially exposed to the substances will know to take precautions.
4 level for biohazard.. which level 1 being minimum risk and Level 4 being extreme risk
Biohazard Level 1: Several kinds of bacteria and viruses including Bacillus subtilis, canine hepatitis, Escherichia coli, varicella (chicken pox), as well as some cell cultures and non-infectious bacteria. Washing one’s hands with anti-bacterial soap, washing all exposed surfaces of the lab with disinfectants, etc). In a lab environment, all materials used for cell and/or bacteria cultures are decontaminated via autoclave.
Biohazard Level 2: Various bacteria and viruses that cause only mild disease to humans, or are difficult to contract via aerosol in a lab setting, such as hepatitis A, B, and C, influenza A, Lyme disease, salmonella, mumps, measles, scrapie, and HIV.
Biohazard Level 3: Various bacteria and viruses that can cause severe to fatal disease in humans, but for which vaccines or other treatment exist, such as anthrax, West Nile virus, Venezuelan equine encephalitis, SARS virus, variola virus (smallpox), tuberculosis, typhus, Rift Valley fever, Rocky Mountain spotted fever, yellow fever, and malaria.
Biohazard Level 4: Exclusively viruses that cause severe to fatal disease in humans, and for which vaccines or other treatments are not available, such as Bolivian and Argentine hemorrhagic fevers,H5N1(bird flu) dengue fever, Marburg virus, Ebola virus, hantaviruses, Lassa fever, Crimean-Congo hemorrhagic fever, and other various hemorrhagic diseases.
However, some occupations carry a higher risk of exposure to infectious disease. These are occupations where there is a risk from blood-borne disease such as Hepatitis B, C and HIV and include:
* hospital, dental and health care personnel
* laboratory workers
* paramedical personnel (such as ambulance officers)
* police and prison officers
* child care workers
* laundry workers
* people handling rubbish and food waste
* people involved in sewage works and plumbing repairs
* people working with children, particularly preschool children, due to the risk of exposure to childhood disease such as measles, mumps and gastric viruses.
Other occupations at higher risk include those involving working with animals, as some animal diseases can infect humans. Typical occupations include those handling livestock (for example, on farms, in sale yards, shearing sheep, and transporting livestock) and workers employed at abattoirs and rendering plants.
Biological hazards can also occur in the food processing industry and laboratories.
Control measures include identifying the hazard, assessing and controlling the risk and implementing a monitoring program.
Additional personal protection can be provided through inoculation against some diseases. This should be discussed with your health practitioner on an individual basis.
APA YANG ANDA SEMUA BOLEH NAMPAK DALAM GAMBAR INI? PERHATIKAN DENGAN BETUL DAN SIAPA TAHU JAWAPAN… LEH SEND KOMEN…
Kita teruskan kelas… sampai semua berasa sangat penat dan sangat jemu untuk bukak laman belog ini.. lantas semua orang rasa sangat annoying dan terlalu semangat untuk tidak menghantar komen2 untuk saya meng apdet belog…
Woohhh!!! Macam menakjubkan perkataan ergonomik ni… wooohhhh woohhhhhh!!!! kena bukak kamus oxford woooohhhhh!!!
tak yah susah-susah belek kamus segala!!! ergonomik ni dah byk orang perkatakan. tanpa niat untuk dengki semua… saya berikan takrifannya.
refer to workplace conditions that pose a biochemical stress to the worker. Such hazardous workplace conditions include, but are not limited to, faulty work station layout, improper work methods, improper tools, excessive tool vibration, and job design problems that include aspects of work flow, line speed, posture and force required, work/rest regimens, and repetition rate.
ha ha.. saja mendengki bagi dalam bahasa Inggeris. Gunakan kamus ya… supaya kamus itu tidak berhabuk… (“,).
ni yang ringkasnya… A physical factor within the environment that harms the musculoskeletal system. Ergonomic hazards include uncomfortable workstation height and poor body positioning.
sambung lagi … sadis sungguh!
*sila tunggu dengan penuh kesabaran …
