Dear Mr. De Clue:

Thank you for your inquiry of August 11, requesting an interpretation regarding the Occupational Safety and Health Administration (OSHA) standard at 29 CFR 1910.23(e)(4), with respect to the 4 inch (10.2 cm) nominal vertical height requirement for toeboards.

The enclosed Walking and Working Surfaces and Personal Protective Equipment Proposed Rulemaking released April 10, 1990, proposes to change the 4 (10.2 cm) inch vertical height requirement for toeboards to 3 1/2 inches (8.9 cm), at 29 CFR 1910.28(b)(7). We expect the Walking and Working Surfaces and Personal Protective Equipment final rule will be released the spring of 1993.

Mr. Terence Smith of the Office of Fire Protection Engineering and Systems Standards, Directorate of Safety Standards Programs, has advised us that the toeboard vertical height requirement most likely will not be lowered from 3 1/2 (8.9 cm) inches in the final rule.

Rather than complying with the OSHA existing requirement of 4 inches (10.2 cm) or the proposed requirement of 3 1/2 inches (8.9 cm) you may rope off the fall area below the billboard platforms to prevent employee access when the platforms are being used.

Thank you for your interest in occupational safety and health. If we can be of further assistance, please contact us.

Sincerely,

Patricia K. Clark, Director
[Directorate of Enforcement Programs]
