FROM:               JOHN B. MILES, JR., DIRECTOR 

SUBJECT:            Misapplication of Power Lawnmower Standard 29 CFR

It has been brought to our attention that in some instances the OSHA standard for consumer type power lawnmowers at 1910.243(e) have been cited by field staff when inspecting commercial lawnmowers.

The OSHA standard at 1910.243(e) derived from ANSI B71.1-1968 pertains only to consumer type lawnmowers used by employees. Commercial type lawnmowers are covered under 29 CFR 1910.212(a)(1) and (a)(3)(ii).

When inspecting commercial type lawnmowers under 1910.212, industry consensus standards should be used to verify hazards, industry knowledge, and appropriate abatement. Whenever an employee hazardous exposure is identified relative to a commercial type lawnmower, ANSI B71.4-1984, Safety Specifications for Commercial, Turf Care equipment should be referred to.
