a temporary combustible structure should never be placed

A temporary combustible structure should never be placed close enough to another building or opening that a single fire could easily spread between them. In many safety codes and training materials, the commonly cited minimum is 100 feet from any other building or tunnel opening, unless a more specific local rule applies.

Key safety idea

• The phrase “a temporary combustible structure should never be placed closer than…” refers to the minimum separation distance that fire codes require between a flammable temporary structure and other buildings, shafts, or stored combustibles.

• Several regulations for construction and tunneling work prohibit combustible sheds or storage within about 100 feet of tunnel or shaft openings and similar critical structures.

Why distance matters

• Combustible temporary structures (sheds, site offices, change houses, storage huts) can ignite quickly and allow fire to spread to nearby buildings if they are too close.

• Separation distance reduces:
  • Radiant heat exposure
  • Ember travel risk
  • The chance that one fire will immediately involve another structure or a critical opening (like a shaft or tunnel).

Variations in actual code requirements

• Different jurisdictions can specify different minimum distances, and sometimes give a general rule such as “no combustible materials stored within 10 feet of a building” for outdoor storage areas, with larger distances for structures and special hazards.

• Fire safety guidance for temporary buildings stresses that the exact number of feet must come from local fire codes, building regulations, or the site’s fire safety plan; the 100‑foot figure appears in multiple regulations but may not be universal.

Practical takeaway for your topic

• For learning or general exam-style questions, the “fill in the blank” statement “A temporary combustible structure should never be placed closer than ___ feet from any other building” is most often answered as 100 feet , reflecting widely used regulatory examples.

• For real-world placement of any temporary combustible structure , the safe approach is to treat 100 feet as a conservative rule of thumb but always confirm the exact required distance with the current local code or the authority having jurisdiction.
