Dear Mrs. Stewart:
Thank you for your letter to the Occupational Safety and Health Administration (OSHA). We apologize for the delay in our response to your letter. You had a specific question regarding a possible OSHA statute for physical lifting procedures. This letter constitutes OSHA’s interpretation of only the requirements discussed and may not be applicable to any questions not delineated within your original correspondence. Your paraphrased scenario and question are below, followed by our response. Arturia prophet v.
Scenario: Your employer is requiring you to constantly lift 50 to 100 pounds.
As per Pressure Vessel Design Manual-Dennis Moss. Vesselsupports.rar: File Size: 495 kb: File Type: rar: Download File - Lifting Lug Design Spreadsheet. Lifting lugs click on button Crosby IP lifting clamps are available in a variety of models to allow the lifting and transferring of steel plates and other materials in a wide variety of industries. These industries include ship building, offshore, aircraft, construction and metal-processing. Topal clamps (Part of the Tractel Group).
Question: Does OSHA have a statute that addresses procedures for lifting heavy objects?
Response: OSHA does not have a standard which sets limits on how much a person may lift or carry. However, the National Institute for Occupational Safety and Health (NIOSH) has developed a mathematical model that helps predict the risk of injury based on the weight being lifted and other criteria. The NIOSH model is based on previous medical research into the compressive forces needed to cause damage to bones and ligaments of the back. The mathematical model is incorporated in the Applications Manual for the Revised NIOSH Lifting Equation, which can be found on the NIOSH website (http://www.cdc.gov/niosh/docs/94-110/). It should be noted, however, that this NIOSH document provides only voluntary guidelines
The difficulty with assessing risks associated with lifting is that weight alone does not determine the risk for back injury. Other factors include:
- How often you are lifting something.
- Whether you bend or twist while lifting.
- How high an object is lifted.
- Where the origin of the lift occurs; specifically, whether it is below knuckle height.
- Whether you hold the object away from you while lifting.
- How long you lift or hold the object.
Depending on these factors, an object that is safe to lift at one time can cause back problems another time.
NIOSH has a lifting equation (discussed in the above-referenced Applications Manual) for calculating a recommended weight limit for one person under different conditions. The lifting equation establishes a maximum load of 51 pounds, which is then adjusted to account for how often you are lifting, twisting of your back during lifting, the vertical distance the load is lifted, the distance of the load from your body, the distance you move while lifting the load, and how easy it is to hold onto the load.
The NIOSH mathematical model and lifting equation are fairly technical, and several state agencies have developed tools that may help you more readily determine whether a job puts you at risk for back injury. The Ohio Bureau of Workers’ Compensation has a calculator for assessing risk levels associated with lifting various weights, which is available at http://www.ohiobwc.com/employer/programs/safety/liftguide/liftguide.asp. Similarly, the Washington State Department of Labor and Industries [and the Oregon State Safety and Health Division have jointly] developed a calculator for analyzing lifting tasks, based on the NIOSH lifting equation, which is available at [http://www.orosha.org/interactive/lifting/lift_safety.html.]
While OSHA does not have a specific standard for the hazard you raised, employee exposure to hazards related to heavy lifting and back injuries may be addressed under Section 5(a)(1) of the OSH Act, commonly referred to as the General Duty Clause. The General Duty Clause states:
Avro bangla software. “Each employer -- shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees..”
If you would like more information on lifting hazards both OSHA and NIOSH have information on their respective websites which can be found at:
