Permanent scaffolding should be built for routine
maintenance operations on aircraft or other standard
configurations. Powered lift platforms or boom machines are
often used to reach high places. Some extend as high as 100
feet. Scissor lifts, the most common type, only go straight up.
Booms can provide greater access where there are obstructions in
the way. Continuous forced-air ventilation may be used to
control any hazardous atmosphere. Gas monitoring during the
operation may be necessary where unsafe conditions could develop.
When painting bridges, towers, or other tall structures, safety
nets or harnesses should be utilized. They not only provide
safety but also result in better workmanship. Safety harnesses
are much preferred to safety belts because they distribute the
shock from the safety line. Some harnesses have breakaway
sections to further distribute the shock. Suppliers of harnesses
provide detailed instructions for proper use.
13.6.3.2 Confined Areas. Confined areas such as fuel storage
tanks, boilers, and utility tunnels present the following
hazards:
a)
Buildup of flammable or explosive atmospheres or
