Who Uses Scaffolds
Workers who use scaffolds can be divided into two groups: erectors/dismantlers and users.
Erectors/Dismantlers: Erectors and dismantlers are those workers whose are mainly responsible for assembling and disassembling scaffolding. This is done before other work can continue, and/or after they have completed the work.
Users: Scaffold users are those whose work requires them, at least some of the time, to be supported by scaffolding.
Qualified Persons
Employers are required to have a qualified person provide training all scaffold erectors, dismantlers, and users. The qualified person must also do adequate pre-planning to ensure the scaffold is erected properly.
Pre-planning includes:
- Determining the type of scaffold necessary for the job,
- Determining the maximum load of the scaffold,
- Assuring a good foundation, and
- Avoiding electrical hazards.
We'll cover responsibilities for qualified person later in the module.
In August, 1992, two workers were erecting an aluminum pump jack scaffold. As they were raising the second aluminum pole, the pole came into contact with an overhead power line.
The pole being raised was 29 feet 10 inches long and the line was 28 feet 10 inches high. The line was approximately 11 feet from the house. One employee died, and the other suffered severe burns and was hospitalized. The surviving employee noted he thought they had enough room to work around the power lines, which were not de-energized or shielded.
