peligrosos

Peligrosos is the plural form of the Spanish adjective peligroso, meaning dangerous or hazardous. It describes persons, objects, situations, or substances that can cause harm, injury, or damage. The feminine plural is peligrosas, and the adjective agrees with the gender and number of the noun it modifies.

In everyday language, peligrosos is used across a wide range of contexts. Examples include animales peligrosos (dangerous animals), actos peligrosos (dangerous acts), materiales peligrosos (hazardous materials), and lugares peligrosos (dangerous places). The term is common in both informal speech and more formal writing.

In safety, health, and regulatory contexts, peligrosos appears in classifications and warnings. It helps designate risks to people or the environment, as in sustancias peligrosas or agentes peligrosos. In these settings, peligrosos is often paired with qualifiers such as para la salud (for health) or para el medio ambiente (for the environment) to specify the nature of the hazard. Labeling, risk communications, and safety data sheets frequently employ the term to alert and guide corrective actions.

Linguistically, peligrosos functions as a descriptive term rather than a prescriptive label. Its use relies on standard Spanish grammar, with agreement in gender and number with the noun it modifies.
