Practice the hazard symbols found on chemical products. What does the pictogram mean?
Instructions for Hazard pictograms
All hazardous chemical products must be clearly marked with a hazard symbol (also called a hazard pictogram or warning symbol) and risk and protection information in most countries including the EU and US. The label informs of damage that can occur during use.
Practice what the danger symbols stated in GHS hazard pictograms mean and pair the image together with the correct description. Hazard pictograms are one of the key elements for the labelling of containers under the GHS. These pictograms are the same as those recommended in the UN Recommendations on the Transport of Dangerous Goods, widely implemented in national regulations such as the U.S. Federal Hazardous Materials Transportation Act.
Level 1Multiple choice - On each level you will get up to ten questions with or without images, video and audio tracks. For each question you will get two or three possible answers. Only one of these is correct. It's up to you to find the right answer. If you guess incorrectly, you may try again, but you will not get any knowledge points for that round.
Level 2Questions with text answers - On each level you will get up to ten questions with or without images, videos and audio files. You must type the correct answer by yourself. If you make a mistake, you get to try again until you find the searched word or phrase. Once you figure out the correct answer, you will get knowledge points. If you're having trouble figuring out the correct answer, you can click on the button labelled Give up. It will reveal the correct answer to that specific question, but you will not get any knowledge points for that round.
The game creator may have allowed you to get feedback on your typing. If so, the textbox, where you type your answer, will turn red or green as you type. The game creator has also decided if the answer is case sensitive, ie if it is important that you type in correct case. Both of these settings may vary between the levels, which you'll be noticed of when you play a level. You may misspell a maximum of three times per question. On your fourth misspelling, the question will be classified as incorrectly answered.
