Fall protection handout
Anchor your fall protection system properly
When I became comfortable with donning a harness, the next hurdle was determining a suitable anchor point. One of my mentors once told me to use the “pickup truck” test method.
He told me that if it looked like a pickup truck could hang from the anchor point, it was probably strong enough to be an anchor point considering a small truck weighs between 5,000 and 7,000 pounds on average. So, tying off to a 2 X 4 isn’t an appropriate anchor point.
While doing fall protection inspections, I often would apply this question to determine if an anchor point an employee was using was adequate.
OSHA section 1910.140(c)(13)(i) says that an anchor point must be capable of supporting 5,000 pounds for each worker. I recommend using the “pickup truck” test method to identify possible anchor point issues, but it shouldn’t be the only standard you use for determining one.
The issue isn’t just how much a worker weighs. The main issue is how much force and energy occurs during the fall. Also, consider how much force the anchor point absorbs. For example, in an average fall where 2,500 pounds of force occurs, a 5,000-pound rated anchor point allows for a 2:1 safety factor and won’t shear off.
A competent person must make a proper assessment to determine if an anchor point is rated correctly.
Here are four tips to help identify approved anchor points at your jobsite:
- Work with a qualified person, such as an engineer, to identify approved anchor points on the jobsite and to ensure they’re capable of supporting 5,000 pounds. The entire fall protection system depends on an adequate anchor point. There can’t be any guesswork. Do the homework and make sure each anchor point is sufficient.
- Ensure job-made anchor points are welded by a certified welder and approved by a professional engineer. Using job-made anchor points is common in building maintenance, especially with tank work. A welder would weld up anchor points onto the tank shell. A certified welder must pass tests showing an ability to produce quality welds using nationally recognized standards.
- Verify a handrail is rated for tie-off and approved in advance by the manufacturer. I’ve seen many different manufactured handrail brands where the sales representative claimed the workers could use the handrail as a tie-off point — this wasn’t always accurate.
Double-check with the manufacturer and get their written approval and engineering specifications showing the handrail is rated adequately. Many times, you’ll need to install the handrail a certain way.
If your planning to fabricate the handrail in the workplace, you’ll need an engineer to assist with determining its rating. OSHA only requires that the handrail be capable of supporting 200 pounds. So, the chances are that the handrail won’t be adequate for tie-off. - Install a horizontal lifeline properly and ensure it’s appropriately rated for every employee using it as an anchor point. Rate the lifeline for 5,000 pounds for every worker attached to it. For example, if there are two workers, rate it for 10,000 pounds.
When using a horizontal lifeline for an anchor point, it too must be installed properly. The steel cable must have an adequate diameter, clips must be installed properly (usually three at each end with proper spacing) and must not have been in service for lifting purposes.
Anchor points must be capable of supporting 5,000 pounds for every worker. Some workers argued about this saying they only weighed about 200 pounds.
