What is the difference between ANSI 4 and ANSI 5?

 

ANSI (American National Standards Institute) / ISEA (Individual Protective Equipment Association) provides a set of standards and ratings for the identification and classification of industrial protective footwear. These standards deal primarily with abrasion and puncture resistance of protective footwear soles.

 

ANSI standards define various types of protective footwear, including ANSI 4 and ANSI 5. These standards are categorized according to the maximum impact and pressure that protective footwear can withstand.

 

1. ANSI 4: ANSI Class 4 is evaluated for the impact resistance of protective footwear. This rating means that they are able to withstand an impact of at least 50 pounds (about 22.7 kg).

 

2. ANSI 5: ANSI Class 5 evaluates the pressure resistance of protective footwear. This rating means that they are able to withstand at least 2,500 pounds (about 1,134 kg) of pressure.

 

It is important to note that the standards and ratings mentioned above are only some of the ANSI / ISEA standards for protective footwear. Other ratings and standards may exist depending on the specific work environment and requirements.

 

When selecting suitable protective footwear, the standards and ratings required should be based on the impacts and stresses likely to be encountered in the specific work scenario. It is important to ensure that you choose protective footwear that meets the requirements of the job and provides appropriate protection for the worker. When purchasing protective footwear, it is best to consult a sales professional or refer to relevant standards for accurate and reliable information.
