Isolation in hazard control means which of the following?

Isolation in hazard control means which of the following?

• A. Substituting with a less hazardous material
• B. General ventilation
• C. Interposing a barrier between the hazard and the people
• D. Reducing exposure time through training

Answer: (C)

Isolation means physically separating the hazard from workers by a barrier or enclosure, creating a protected zone. It’s an engineering control that keeps people out of the hazard area rather than relying on ventilation, time limits, or PPE. Interposing a barrier between the hazard and the people fits this concept perfectly—it could be a sealed enclosure, a glovebox, a protective wall, or any structure that prevents direct exposure. General ventilation dilutes or removes contaminants but does not by itself separate people from the hazard. Reducing exposure time through training is an administrative control. Substituting with a less hazardous material tackles the hazard at the source rather than isolating people from it. So, creating a physical barrier to keep the hazard away from people best embodies isolation.
