episod 2 …

adakah ini boleh dikategorikan sebagai hazard?

atau ini … ?

itu iklan sahaja… takder kaitan dengan tajuk hazard dalam kelas ini.

kita sambung isu hazard …,

hazard kimia
Punca??? daripada bahan-bahan kimia.
mengapa ia bahaya???

i. bahan Solven- ia boleh menghakis.. (menghakis?… sangat bahaya)
ii. bahan Racun-mematikan saraf (ini lagi bahaya)
iii. bahan Asbestos- asbestosis
Why is asbestos dangerous? Breathing in air containing asbestos fibres can lead to asbestos-related diseases, mainly cancers of the lung and chest lining. Asbestos-related disease is the biggest occupational health killer within the UK with approx 3,500 people (at 2005 figures) currently dying each year, 25% of these once worked in the building and maintenance trades and often would have worked unknowingly on asbestos containing materials. (sumber: OSHA)
Boleh lihat gambar perbezaan keadaan paru-paru yang sihat dan yang rosak. (Annoying sangat sebab tiap kali kena tunjuk gambar!)

Gambar paru-paru yang sihat…

Paru-paru yang rosak.. kerana asbestos..

Bagaimana imej peparu seorang perokok agaknya ya? Sila bayangkan …

iv. bahan Cadmium- memudaratkan sel
v. bahan Arsenik- memusnahkan sel-sel dalam badan
vi. bahan Silika- silikosis
… dan sebagainya

to be continue…
