What is heavy duty scaffold rated for?
Light Duty – 25 pounds per square foot. Medium Duty – 50 pounds per square foot. Heavy Duty – 75 pounds per square foot. These ratings are based on the intended load, which is calculated by dividing the total weight to be placed between two spans of scaffolding by the total area between the two spans.
What is the working load limit of a scaffolding?
875 pounds
The type of scaffolding being used is rated as light-duty, or 25 pounds per square foot. Multiply 35 square feet by 25 pounds per square foot and the scaffolding can be loaded with no more than 875 pounds.
Can scaffolds be loaded in excess of their maximum intended rated capacity?
Scaffolds and scaffold components shall not be loaded in excess of their maximum intended loads or rated capacities, whichever is less.
What is the maximum load rating for a heavy duty work platform per bay?
675 kg
Heavy Duty – up to 675 kg per platform per bay including a concentrated load of 200 kg. Platforms should be at least 1000 mm wide.
Can I use a 2×12 for scaffolding?
2 pine boards may be used as a scaffold platform; whether §1926.451(a) and §1926.451(f)(16) are applicable when erecting and dismantling scaffolds.
What is the leading cause of scaffold accidents?
According to a recent BLS report, more than 70 percent of scaffold accident injuries are caused by: Scaffold support or planking giving way, either due to defective or damaged equipment or improper assembly, leading to falls and injuries to those below.
What is the maximum weight load of a catenary scaffold?
(r) “Catenary scaffolds.” (1) Maximum intended load — 500 lbs. (2) Not more than two employees shall be permitted on the scaffold at one time. (3) Maximum capacity of come-along shall be 2,000 lbs. (4) Vertical pickups shall be spaced not more than 50 feet apart.
Can you not work on a scaffold until?
Employees are not permitted to work on those construction or facility surfaces until it has been determined that the surfaces have the requisite strength and structural integrity to support the workers.
Do scaffold erectors need fall protection?
Employers are required to provide fall protection for employees erecting or dismantling supported scaffolds where the installation and use of such protection is feasible and does not create a greater hazard. In this scenario fall protection is already being used.
What is the maximum gap between scaffold and structure?
Originally Answered: What is the maximum gap between scaffold and structure? For normal maintenance work, it is 150 mm to 300mm. If you are doing the major installation of adding structural members, in such case it is 150 mm to 600 mm to facilitate enabling tools to e operated or gap to inserts member etc.
How many working platform are there is heavy duty scaffolds?
Heavy Duty Scaffold May have two working platform bays at any one time.
What does a yellow tag on scaffold mean?
CAUTION
Yellow – “CAUTION” tag(s), will replace all green “Safe Scaffold” tag(s) whenever the scaffold has been modified to meet work requirements, and as a result could present a hazard to the user. This tag indicates special requirements for safe use.
What’s the weight limit for medium duty scaffolding?
Medium Duty – 50 pounds per square foot. Heavy Duty – 75 pounds per square foot. These ratings are based on the intended load, which is calculated by dividing the total weight to be placed between two spans of scaffolding by the total area between the two spans.
What are the different types of scaffold load ratings?
Regulations across North America can vary, but the scaffolding industry has generally agreed on the following three load rating categories: Light Duty: Up to 25 pounds per square foot (122 kg/m2) of platform area, evenly distributed. Medium Duty: Up to 50 pounds per square foot (244 kg/m2) of platform area, evenly distributed.
How big is a square foot of scaffolding?
Example 2: The scaffold size is 7 feet long by 5 feet wide – a total square footage of 35 square feet. The type of scaffolding being used is rated as light-duty, or 25 pounds per square foot. Multiply 35 square feet by 25 pounds per square foot and the scaffolding can be loaded with no more than 875 pounds.
What are the safety factors for a scaffold?
The scaffolding selected must be able to withstand this load (the safety factor of four is designed into the rated load capacity). Scaffold and scaffold components shall not be loaded in excess of their maximum intended load or rated capacity, whichever is less. The rated load capacity of a scaffold is defined below.
