Tow Strap Safety Bulletin

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, caution 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— do not 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 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, 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.

The entire tow strap must be inspected before each use and it shall be if ANY of the following are detected:

• Holes, tears, cuts, snags or embedded materials. 

• Broken or worn stitches in the load-bearing splices. 

• Knots in any part of the webbing. 

• Acid or alkali burns. 

• Melting, charring or weld spatters on any part of the webbing.

• Excessive abrasive wear or crushed webbing. 

• Signs of ultraviolet (UV) light degradation. 

• Distortion, excessive pitting, corrosion or other damage to hooks, shackles, or end fitting(s). 

• Any conditions which cause doubt as to the strength of the tow strap. 

3. Avoid Actions That Can 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 ensure the longevity and safety of your tow straps.

Where to Find Additional Information

This bulletin is not a comprehensive guide to ensure you are fully trained or knowledgeable in towing practices or tow strap use. However, it provides essential information on the safe and proper use of tow straps. If you require additional guidance regarding tow straps or your responsibilities under applicable regulations and standards, consult your employer.

Both you and your employer should utilize available resources to ensure you are sufficiently trained and informed to use tow straps safely and effectively.
