Identify two common on-scene hazards and one safety measure for each.

• A. Loud electrical wires – maintain distance and disallow contact; Structural collapse risk – establish safe zones and monitor integrity.
• B. Ice on ground – slip; Heat from flames – ignore.
• C. Loud noise – earplugs; Smoke – breathe normally.
• D. None.

Answer: (C)

Two common on-scene hazards are loud noise and smoke. Loud noise can cause hearing damage, so wearing hearing protection like earplugs or earmuffs reduces exposure and protects hearing. Smoke is dangerous because it contains toxic gases and obscures vision; the best safety measure is to stay low and move toward fresh air to minimize inhalation, using respiratory protection if you’re trained and equipped.
