SUBJECT: OSHA Standard 29 CFR 1926.550(g) Cranes and
Derricks Suspended Personnel Platforms
Following the October 3, 1988, effective date of OSHA Standard 29 CFR
1926.550(g) (Cranes and Derricks Suspended Personnel Platforms), former OSHA
Training Institute students have requested clarification regarding OSHA's
policy on when and how it it permissible for employees to be hoisted on the
load lines of cranes and derricks.
This is to advise you that the following guidelines relating to this topic
are being provided at the Institute:
- Employees may be hoisted on the load lines of cranes,
on construction sites, only if it is more hazardous or infeasible to reach
the worksite by conventional means.
- Employees are not permitted to "ride the ball" under
any circumstances. Employees may only ride in a personnel platform that
complies with the requirements set forth in OSHA Standard 29 CFR
- All cranes that are used to hoist employees are
required to be fitted with anti-two blocking devices.
If members of your staff have any questions regarding this matter, please
contact Mr. Henry H. Hale, Chief of the Occupational Safety Training Branch,
on FTS 352-2500.
