Which COSHH sign would indicate a harmful substance?

Explanation:
The main idea is recognizing what each hazard pictogram signals on COSHH labels. The harmful symbol uses a general warning mark (an exclamation point) to indicate substances that can cause irritation, sensitization, or mild acute toxicity. It flags potential harm but is not as severe as substances marked with the toxic symbol. The toxic symbol (skull and crossbones) warns of substances that can cause death or serious harm even in small amounts, while the flammable symbol shows a fire risk and the corrosive symbol warns that the chemical can damage skin, eyes, or metals. So the sign indicating a harmful substance is the one with the general warning mark.
