What are the two types of areas where cutting and welding can be permitted?

The correct response identifies that cutting and welding can be performed in an area made fire safe by removing combustibles. This is crucial because both processes generate heat and sparks, which can ignite nearby flammable materials and create fire hazards. By ensuring that the area is clear of combustibles, the risk of fire is significantly reduced, providing a safer environment for the welder and those nearby.

This principle is fundamental in safety guidelines and regulations regarding cutting and welding operations, as it prioritizes the reduction of fire hazards which can lead to serious accidents and damage. Removing combustibles not only protects the workers but also minimizes potential damage to property and equipment in the vicinity.

While other locations mentioned also contribute to safety, such as a designated area for cutting and welding or locations with controlled ventilation to ensure air quality, the removal of combustibles directly addresses the immediate fire risk that accompanies these operations.
