Berapa kadar karbon monoksida (CO) yang aman dalam udara yang kita hirup? Pelajari efek keracunan CO dan bagaimana batas-batasnya ditentukan.
Ada banyak standar dan panduan untuk batas aman, termasuk hasil berbagai studi kesehatan dan keselamatan kerja tentang efek paparan yang lama. Untuk menyelam, situasinya berbeda. Jadi, berapa batas aman untuk penyelaman rekreasi dengan paparan yang jauh lebih singkat daripada penyelam angkatan laut? Khususnya, berapa batas aman untuk karbon dioksida (CO2), kontaminan potensial yang paling melimpah?
