Temel Güvenlik ve Uyarı İşaretleri Kılavuzu

Temel Güvenlik İşaretleri ve Özellikleri
Risk piktogramları, sağlık ve güvenlik amacıyla kullanılan temel uyarı işaretleridir. Bu işaretleri tanımak, laboratuvarda güvenle çalışmanızın ilk adımıdır.
Patlayıcı maddeler etkisiyle patlamaya sebep olabilecek kimyasallardır. Bunlar ateş, kıvılcım ve ısıdan uzak tutulmalıdır. Sonucu ciddi yaralanmalar olabilir, bu yüzden her zaman uygun mesafede kalın!
Oksitleyici (yakıcı) maddeler ortamda alev alabilir ve yanıcı maddelerle temas ettiğinde patlayabilir. Bu nedenle yanıcı maddelerden uzak tutulmalıdır. Parlayıcı maddeler ise sıfır derecenin altında bile alev alabilen ve kaynama noktaları 35°C'den düşük olan tehlikeli kimyasallardır.
Zehirli (toksik) maddeler ağız, deri veya solunum yoluyla vücuda girerek zehirlenme yapabilir. Anında ilk yardım gerektirebilecek kadar tehlikeli olabilirler.
⚠️ Dikkat! Kimyasallarla çalışırken daima koruyucu ekipman kullanın. Bir damla zehirli madde bile ciddi sağlık sorunlarına yol açabilir.
Diğer Tehlikeli Madde İşaretleri
Korozif (aşındırıcı) maddeler temas halinde deri dokularını tahrip edebilir ve metalleri aşındırabilir/paslandırabilir. Bu maddelerle çalışırken koruyucu giysiler giyilmeli, buharı solunmamalı ve metallerden uzak tutulmalıdır.
Çevreye zararlı maddeler suya ve doğadaki canlılara zarar verir. Rastgele doğaya atılmamalıdır. Tahriş edici maddeler ise deri ve gözlere zarar verebilir. Buharları kesinlikle solunmamalı ve vücudu korumak için her zaman koruyucu giysiler giyilmelidir.
Sağlık etkisi olan maddeler ozon tabakasına zarar verebilir, insan sağlığını uzun veya kısa sürede bozabilir ve kanser riski taşıyabilir. Bu maddelerden kaçınılmalı, ağız yoluyla alınmamalı ve solunmamalıdır.
Basınç altındaki gazlar açığa çıktığında soğuk olabilir ve ısıtıldığında patlayabilir. Temastan kaçınmak gerekir. Radyoaktif maddeler ise radyasyon yayar ve canlı dokularda kalıcı hasarlara neden olur. Çok tehlikelidir! Bu işaretin bulunduğu bölgelerde dolaşılmamalı ve özel giysiler kullanılmalıdır.
💡 Pratik bilgi: Bir laboratuvara girdiğinizde ilk yapmanız gereken şey, tüm güvenlik işaretlerini kontrol etmek ve acil çıkış noktalarını belirlemektir.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
