Concentrated sulfuric acid typically has a hazard symbol of a skull and crossbones, indicating it is toxic, along with a corrosion symbol, indicating it is corrosive.
Because if there were to be an accident and the contents were spilled the emergency services have to be able to respond appropriately. E.g. If a corrosive substance spilled they need to know what it is and that it is corrosive. If the symbol on the same truck was 'flammable' then the response wouldn't be appropriate and people would be trying to cope with a different sort of spillage.
Yes, a solution is considered concentrated when there is a large amount of solute (salt in this case) dissolved in a given amount of solvent (water in this case). With 20ml of salt in 50ml of water, the concentration of the solution would likely be high.
The symbol for a concentrated acid is typically shown as "conc. HX," where "X" represents the specific acid. For example, concentrated sulfuric acid would be written as "conc. H2SO4."
On a container of oven cleaner in a spray can, you would likely find symbols indicating that the product is flammable, may irritate skin or eyes, and should be kept out of reach of children. For bleach fluids, you may find symbols warning of skin and eye irritants, advisories to avoid mixing with other chemicals, and guidance on proper ventilation during use.
You would most likely find a symbol indicating that the substance is corrosive, such as the corrosive symbol (skull and crossbones). It is important to handle concentrated acids with caution due to their corrosive nature.
Concentrated sulfuric acid typically has a hazard symbol of a skull and crossbones, indicating it is toxic, along with a corrosion symbol, indicating it is corrosive.
The hazard symbols that may be found on drain cleaner could include: corrosive symbol (causes burns), health hazard symbol (may be harmful if ingested/inhaled), and environmental hazard symbol (harmful to aquatic life).
All of the symbols are shaded.
The hazard symbol that would be on the lorry depends on the specific hazardous material being transported. Common hazard symbols include those for flammable, corrosive, toxic, and explosive materials as per international regulations.
An emergency vehicle approaching
You can usually find hazard symbols near dangerous materials or areas like maybe you would find lots of radioactive hazard symblols in chernobyl, where the atomic explosion happened.

You would likely see the hazard symbol for toxic substances on an insecticide, indicating that it is harmful if swallowed, inhaled, or absorbed through the skin. This symbol typically features a skull and crossbones.
Most likely - it would need to be tested for mold.
