What confined space standards apply to construction companies?

Some confined space entry restrictions are built into the Part 1926 construction regulations. Some examples of the construction confined space regulations are:

• 1926.21(b)(6)(i)-(ii) — Safety Training and Education
• 1926.154(a)(1)-(2) — Temporary Heating Devices
• 1926.350(b)(4) — Gas Welding and Cutting
• 1926.352(g) — Fire Prevention
• 1926.353(b)(1)-(2) — Ventilation and Protection in Welding, Cutting, and Heating
• 1926.651(g)(1)-(2) — General Requirements
• 1926.956(a)-(b)(1)-(3) — Underground Lines

Other confined space requirements may be found throughout Subpart S (1926.800–1926.804 Underground Construction, Caisson, Cofferdams and Compressed Air.)

OSHA’s general industry standard for confined spaces (29 CFR 1910.146) became effective April 15, 1993. However, it does not apply to construction since confined space entries for construction employees pose conditions that are unique to the industry. The general industry standard may, however, apply to construction companies that perform confined space work at industrial sites.
