Unit IV Quiz

A worker is welding on structural steel near a gantry crane. They are anchored 1 foot below their D-ring using a 6 foot shock-absorbing lanyard. Calculate the free-fall distance based upon the D-ring location. Show all calculations.

There is no minimum word count for this question, however, you must show your work/calculations.

Calculating free fall distance based on D-ring location:

D-ring ABOVE Anchor: Free fall distance = Lanyard length + Distance from D-ring to anchor

The free fall distance comes to 7 ft. which exceeds the maximum of 6 ft. per 29 CFR 1926.502(d)(16)(iii). A 5-foot shock-absorbing lanyard should be used at a minimum for this task to meet safety measurements.

A construction worker is anchored level with their D-ring, using a 6 foot rip-stitch lanyard. The Back D-ring height is 6.5 feet. Deceleration distance is 3.5 feet. The Safety factor is 2 feet. Calculate the total Fall Clearance distance. Show all calculations.

There is no minimum word count for this question, however, you must show your work/calculations.

Total Fall Clearance = Free Fall Distance (length of lanyard +/- distance from D-ring to anchor) + Deceleration Distance (if unknown assume 3.5 ft.) + D-ring Shift (if unknown assume 1 ft.) + Back D-ring Height (if unknown assume 5 ft.) + Safety Factor (typically 2 ft.)

Your employee is working on a scaffold, anchored to a trolley anchor 3 feet above their D-ring. They are using a 6 foot shock absorbing lanyard. The Back D-ring Height is 5 feet, and the Safety Factor is 2. The deceleration distance is 3 feet. Calculate the total Fall Clearance distance. Show all calculations.

There is no minimum word count for this question, however, you must show your work/calculations.

Total Fall Clearance = Free Fall Distance (length of lanyard +/- distance from D-ring to anchor) + Deceleration Distance (if unknown assume 3.5 ft.) + D-ring Shift (if unknown assume 1 ft.) + Back D-ring Height (if unknown assume 5 ft.) + Safety Factor (typically 2 ft.)

Explain five strategies for establishing an effective electrical safety program. What are some additional electrical safety program requirements for protection of workers whom must perform maintenance, service, or troubleshooting on equipment that is not, or cannot be, de-energized?

Your response must be at least 200 words.

Below are five of the strategies The National Institute for Occupational Safety and Health (NIOSH) recommends following in order to establish an effective electrical safety program.

Some electrical safety requirements for protection of workers whom must perform maintenance, service, or troubleshooting on equipment that is not, or cannot be, de-energized are listed below.

1. Develop and implement a comprehensive safety program and, when necessary, revise existing programs to address thoroughly the area of electrical safety in the workplace. This means if needed start at the bottom and create a plan to ensure your employees will remain safe in the work center.
2. Provide all workers with adequate training in the identification and control of the hazards associated with the electrical energy in their workplace. If employees are not trained thoroughly to spot hazards unnecessary injuries could occur.
3. Conduct safety meeting regularly. This encourages the employees to remain vigilante and aware of electrical safety in the workplace and also lets employees know that leadership cares about their safety.
4. Actively encourage all workers to participate in workplace safety. This falls in line with strategies number one and three you can create incentive programs to help with reporting safety issues during monthly meetings and encourage participation through the incentive program.
5. Conduct scheduled and unscheduled safety inspections at work sites. This helps ensure employees are following safety precautions at all times and encourages safe work practices.

1. Preform a flash hazard analysis in accordance with NFPA 70E, Article 130.3, or use table 130.7(C)(9)(a) (hazard/Risk Category Classifications) to identify the hazard/risk category of the job tasks that must be preformed on the energized equipment.
2. Establish a flash protection boundary around the equipment in question in accordance with NFPA 70E, Article 130.3(A).
3. Select the PPE that will be worn by the worker(s) who will preform the tasks in question on the energized equipment from table 130.7(C)(10) (Protective Clothing and PPE Matrix) based on the level of risk identified for these tasks in 130.7(C)(9)(a) in the first step above.
