Once the tow strap is cleaned and dried, it is important to inspect it for any signs of wear, fraying, or damage. Ensure the strap is in optimal condition before using it again. If any damage is detected, it is recommended to replace the strap to ensure safety during use.
Initial Inspection
The initial level of inspection involves checking each tow strap before it is put into service. It is essential that the correct tow strap is being used and that it meets the applicable requirements. The inspection is performed upon receipt to ensure no damage has occurred during transit.
The tow straps must also be verified to be the correct product as ordered and to comply with the manufacturer’s specifications. Without printed product specifications, this comparison cannot be accomplished. If written records for individual tow straps are to be maintained, documentation should be initiated at this level of inspection.
Record keeping at the initial level of inspection is not required.
Frequent Inspection
The frequent level of inspection is one that is done by the user or other designated person daily or before each shift in normal service conditions. In severe service conditions, the tow strap must be inspected before each use.
The entire tow strap should be thoroughly examined and removed from service if damage is detected.
If you are unsure whether the daily or pre-shift inspection has been done, take the time to inspect the tow strap before use. Never assume that someone else has completed the inspection.
A qualified person must also ensure that the tow strap is suitable for the intended use, hitch, load, and environment. Any condition that may present a hazard shall result in the tow strap being removed from service.
Written inspection records are not required for frequent inspections.
Periodic Inspection
All tow straps must be inspected periodically by designated personnel at regular intervals. To validate the frequent level of inspection, the periodic inspection should be done by someone other than the individual(s) who performs the frequent inspection.
The interval is based on:
- Frequency of use
- Severity of service conditions
- Nature of the work being performed
- Experience gained during the inspection of tow straps used in similar circumstances
- Recommendations to prevent damage should be evaluated to improve the service life of replacement tow straps.
Periodic inspection intervals shall not exceed one year.
The following time interval guidelines are recommended for periodic inspections:
- Normal Service: Yearly
- Severe Service: Monthly to Quarterly
- Special Service: As recommended by a qualified person
Written records of the most recent periodic inspection should be maintained. Reference to a unique tow strap identification number is not required.
Tow straps removed from service that are not repairable shall be destroyed and rendered completely unfit for any future use.
Overview
This bulletin contains important safety information about the use of tow straps. However, it DOES NOT contain all the information you need to know about handling, manipulating and towing vehicles safely. It is your responsibility to use tow straps safely and to consider all risk factors prior to using any tie down system. Failure to do this may result in severe INJURY or DEATH due to tow strap failure.
1. All Tow Strap Users Must be Trained and Knowledgeable
All tow strap users must be trained on the proper use of tow straps, including selection and inspection, cautions to personnel and environmental effects. A "qualified person" is described as:
“Who by possession of a recognized degree, certificate of professional standing or by extensive knowledge, training and experience has successfully demonstrated the ability to solve or resolve problems related to the subject matter and work.”
It is important that all tow strap users be knowledgeable about the safe and proper use and application of tow straps and securement practices and be thoroughly familiar with the manufacturer's recommendations and safety materials provided with each product. In addition, all users must be aware of their responsibilities as outlined in all applicable federal, state, provincial, and local regulations and industry standards (where applicable).
If you are unsure whether you are properly trained and knowledgeable, or if you are unsure of what the standards and regulations require of you, ask your employer for information and/or training—use tow straps until you are absolutely sure of what you are doing. Remember, when it comes to using tow straps, lack of skill, knowledge and care can result in severe injury or death to you and others.
2. Tow Straps Must Be Adequately Protected From Damage
2a. Avoid Environmental Degradation
Environmental factors such as exposure to sunlight, dirt, or gritty-type matter and cyclical changes in temperature and humidity, can result in an accelerated deterioration of tow straps. The rate of this deterioration will vary with the level of exposure to these conditions and with the thickness of the strap webbing. Tow straps that are used regularly should generally be permanently removed from service within a period of 2 to 4 years. All tow straps that are exposed to these conditions should be highly scrutinized during their inspections.
- Visible indications of such deterioration can include the following:
- Fading of webbing color.
- Uneven or disoriented surface yarn of the webbing.
- Shortening of the tow strap length.
- Reduction in elasticity and strength of the tow strap material due to exposure to sunlight, often evident by accelerated abrasive damage to the surface yarn of the tie down.
- Breakage or damage to yarn fibers, often evident by a fuzzy appearance of the web.
- Stiffening of the web, which can become particularly evident when tow straps are exposed to outdoor conditions without being used or cyclically tensioned.
3. Avoid Actions that Cause Damage to Tow Straps
You should always avoid any action that causes the types of damage identified in the previous section of this Safety Bulletin, including (but not limited to):
- Dragging tow straps on the ground, floor, or over abrasive surfaces.
- Twisting, kinking, or knotting the tie down.
- Exposing tow straps to damaging acids or alkalis.
- Using tow straps or allowing exposure to temperatures above 194°F (90°C) or below -40°F (-40°C).
- Using the tow strap against edges or surfaces that could damage the strap webbing.
- Running/driving over tow straps with a vehicle or other equipment.
Tow straps are affected by some chemicals ranging from little to total degradation. Time, temperature, and concentration factors affect the degradation. For specific applications, consult the manufacturer. In addition, water absorption can decrease a nylon tie down's strength by as much as 10–15% (its strength returns when the tie down dries completely). Consult a tie down manufacturer for specific application loss factors.
4. Always Use Tow Straps Properly
Tow straps must be used by trained individuals who understand the towing or recovery process. The following points are critical for safe and effective use.
4a. Assess the Load
Before using a tow strap, ensure the Minimum Breaking Strength (MBS) of the strap is at least three times the Gross Vehicle Weight (GVW) of the vehicle being towed. For example, if the MBS of the strap is 300k, the GVW of the vehicle should not exceed 100k. If the vehicle is unevenly balanced or has an unstable load, make sure to use the correct setup, such as a single line, double line, bridle, or V-brace, to ensure the load is properly distributed during towing.
4b. Use the Appropriate Tow Strap System
Choose the correct number of tow straps and ensure they are placed at the proper anchor points on both the towing and towed vehicles. The tow straps should be compatible with the weight of the vehicle and environmental conditions. Always consider the angle at which the strap is used—an improper angle can weaken the strap and reduce its effectiveness.
4c. Do Not Misuse Tow Straps
Tow straps are designed specifically for towing. Never use them for securing, lifting, or any other purpose outside of towing or recovery. Misusing them can lead to equipment failure or accidents.
5. Make Sure All Personnel are Clear of Tow Operations and Alert to Risks
Even with the best preparation and adherence to safety measures, unforeseen issues can still arise when using tow straps. All personnel must remain alert to potential risks throughout the towing process. Before applying or releasing tension on the tow straps, ensure the vehicle or equipment being towed is stable and secure.
Extra caution is essential when releasing tension, as vehicles or loads may shift unexpectedly, creating a risk of sudden movement. Have a clear plan for personnel to move to a safe location if the situation becomes hazardous. Additionally, ensure that everyone involved maintains stable footing to prevent slips or falls. Stay mindful of hazards associated with positioning or tossing tow straps, and take care to avoid creating risks for others in the vicinity.
6. Properly Store and Maintain Tow Straps
To ensure the longevity and reliability of tow straps, they should be stored in a cool, dry, and dark location. Keep them away from environmental or mechanical hazards, such as weld spatter, sharp edges, grinding debris, heat sources, or chemical exposure, which could cause damage.
Tow straps should remain clean and free from dirt, grease, or other contaminants. Clean straps with mild soap and water, ensuring they are thoroughly dried before returning them to storage or using them again. Proper storage and maintenance help prevent wear and extend the life of your tow straps.
